Allen & Heath ZED-24 Review: 24-Channel Analogue Mixer Built for Serious Work

If you've ever tried running a 16-channel mixer at a medium-sized venue and found yourself wishing for just a few more inputs, you already understand why the Allen & Heath ZED-24 exists. It sits in that sweet spot where you've genuinely outgrown compact mixers but don't necessarily need — or want — the complexity of a full digital console. For bands with multiple vocalists, churches with a worship team, or venues running regular live events, 24 channels of clean analogue signal path can be exactly what the situation demands.

Allen & Heath have been building mixers in Cornwall, England since 1969, and the ZED series represents their commitment to keeping high-quality analogue mixing accessible. The ZED-24 isn't just a bigger version of the ZED-12FX or ZED-16FX — it's designed from the ground up for scenarios where channel count, routing flexibility, and audio quality all need to work together without compromise. Let's dig into what makes this desk tick and whether it's the right fit for your setup.

What You're Actually Getting: The ZED-24 at a Glance

The ZED-24 is a 24-channel analogue mixing console featuring 16 mono mic/line channels and 4 stereo input channels, giving you a total of 24 input sources. It includes Allen & Heath's acclaimed DuoPre preamps, a built-in USB audio interface for direct-to-computer recording, 4 aux sends (2 pre-fade for monitors, 2 post-fade for effects), and a comprehensive EQ section on every channel. There's also a dedicated stereo return for external effects processors.

What separates this from the cheaper mixers flooding the market isn't necessarily the feature list — it's the execution. Every component, from the preamps to the EQ curves to the physical build, reflects decades of mixer design experience. That matters more than most people realise when you're in the middle of a gig and need things to just work.

DuoPre Preamps: Why They Actually Matter

Allen & Heath developed their DuoPre preamp technology specifically for the ZED series, and it's genuinely one of the standout features of this mixer. Each preamp uses a two-stage design — the first stage handles the initial gain with very low noise, while the second stage provides additional gain when needed without degrading the signal. The result is a preamp that delivers clean, detailed audio across a wide gain range.

In practical terms, this means you can plug in a dynamic mic like an SM58 and get a clean, full signal without cranking the gain to the point where hiss becomes noticeable. Equally, you can handle hot signals from active DI boxes or keyboards without clipping. The DuoPre design offers around 69dB of gain range with an equivalent input noise (EIN) of -127dBu — figures that genuinely compete with standalone preamps costing several hundred dollars each.

For Australian users working in diverse settings — from quiet acoustic sets at wine bars to louder pub rock gigs — this flexibility is invaluable. You're not constantly fighting the preamps to get a usable signal; they meet you where you need them.

Preamp Performance in Real Scenarios

Condenser microphones, which typically output a hotter signal, work beautifully with the DuoPre design. The 48V phantom power is switchable in groups, which is standard for this price range but still worth noting — you'll want to plan your channel layout so phantom-powered mics are grouped together. Ribbon microphones, which need very clean gain with minimal noise, also benefit from the low-noise first stage, though you'll obviously want to ensure phantom power is off on those channels.

Where the DuoPre really shines is with dynamic microphones at a distance — think drum overheads using SM57s or room mics. These scenarios demand a lot of clean gain, and cheaper preamps tend to introduce audible hiss. The ZED-24 handles this with noticeably less noise than competing mixers in its price bracket.

Channel Strip: Thorough Without Being Overwhelming

Each of the 16 mono channels on the ZED-24 features a surprisingly comprehensive channel strip. You get a high-pass filter (HPF) at 100Hz, which is essential for cutting low-frequency rumble from vocal mics and instruments that don't need sub-bass energy. The 4-band EQ includes two swept mids — and this is where the ZED-24 pulls ahead of most mixers at its price point.

The EQ That Makes the Difference

Having two swept mid bands (rather than fixed-frequency mids) gives you significantly more control over the most critical part of the frequency spectrum. The high-mid sweeps from around 600Hz to 6kHz, while the low-mid covers roughly 120Hz to 1.2kHz. This means you can pinpoint and cut a boxy frequency on a vocal, scoop out muddiness on an acoustic guitar, or add presence to a snare drum — all with precision that fixed-EQ mixers simply can't match.

The high and low shelving EQs round out the picture. Allen & Heath have voiced these curves based on decades of feedback from live sound engineers, and they're musical rather than clinical. A gentle boost on the high shelf adds air and sparkle without harshness, while the low shelf adds warmth without turning everything to mud. These are subjective qualities, sure, but they're consistently praised by engineers who've used A&H desks extensively.

The stereo channels get a slightly simplified 3-band EQ with a swept mid, which is perfectly adequate for keyboards, backing tracks, and other stereo sources that typically need less surgical attention.

Routing and Aux Sends: Flexible Enough for Most Scenarios

The ZED-24 provides 4 auxiliary sends — aux 1 and 2 are pre-fade (ideal for monitor mixes), while aux 3 and 4 are post-fade (suited for effects sends). For many live sound applications, this is the practical minimum, and it covers the most common scenarios well.

Two pre-fade monitor sends mean you can create two independent monitor mixes — typically one for the vocalist and one for the drummer or instrumentalists. If you're running in-ear monitors for a small band, two mixes might be all you need. For larger ensembles requiring more monitor mixes, you'd be looking at the step up to a digital console with more aux buses, but for community events, small venues, and function bands, two monitor sends handle the job.

The two post-fade aux sends work brilliantly for routing to external effects units — a reverb and a delay, for instance. Since they're post-fade, the effect level tracks with your fader moves, which is exactly what you want for effects processing in a live context.

Main Mix Bus and Groups

The ZED-24 features a main stereo mix bus with dedicated left and right outputs on balanced XLR connectors. There's no group bus system on this model, which is worth noting — if you need subgroups for grouping drums or backing vocals together, you'll need to look at larger format consoles. For straightforward mixing where each channel goes directly to the main mix, the ZED-24's routing is clean and logical.

There is, however, a dedicated mono output that can serve as a separate feed — useful for sending a mono mix to a separate zone, a recording device, or a broadcast feed. This kind of practical routing option shows Allen & Heath's understanding of real-world requirements.

USB Audio Interface: Recording Made Simple

The built-in USB interface on the ZED-24 provides a stereo send and return to your computer. It captures the main mix bus, which means you can record your live mix directly into a DAW (Digital Audio Workstation) like Logic Pro, Ableton Live, GarageBand, or Audacity with zero additional hardware.

Now, let's be upfront about what this is and isn't. This is a stereo USB interface — you're recording the two-track mix, not individual channels. If you need multitrack recording of every channel simultaneously, you're looking at a digital mixer with built-in multitrack USB or a separate multichannel audio interface. But for capturing live recordings of gigs, rehearsals, podcast sessions, or creating a stereo mix for later reference, the USB connection is genuinely useful and sounds excellent thanks to the quality of the analogue signal path feeding it.

The USB return also means you can play backing tracks from your laptop directly through the mixer without needing a separate audio interface. For function bands, solo performers, and theatre productions that rely on backing tracks, this is a practical convenience that simplifies the signal chain.

Recording Workflow Tips

One of the smartest ways to use the USB recording on the ZED-24 is for rehearsal capture. Set up your mix, hit record in your DAW, and you've got a reference recording of every rehearsal. Over time, this becomes an invaluable tool for identifying arrangement issues, balance problems, and performance improvements that you simply can't hear in the moment.

For podcast and content creation setups, the ZED-24 might seem like overkill — but if you're running a panel show with multiple hosts and guests, having 16 dedicated mic channels with professional-grade preamps and EQ, plus direct USB recording, actually makes a lot of sense. It's a one-box solution that sounds significantly better than most USB podcast mixers.

Build Quality and Physical Design

Allen & Heath have always been known for building mixers that survive the real world, and the ZED-24 continues that tradition. The chassis is a robust steel and aluminium construction that feels solid without being excessively heavy. The faders have a smooth, consistent action — they're not the long-throw motorised faders you'd find on a digital console, but they track accurately and feel professional under your fingers.

The knobs have a satisfying resistance that prevents accidental bumps from shifting your carefully dialled-in settings — anyone who's had a singer lean on the desk and knock the EQ sideways mid-song will appreciate this. The layout is clean and logical, with clear labelling and colour-coded sections that make it easy to navigate even in dim stage lighting.

At roughly 740mm wide and weighing approximately 11kg, the ZED-24 is portable enough for regular transport but substantial enough to feel planted on a table or in a rack. It's not a flyweight, but two people can easily carry it, and it fits in the back of most cars without drama.

Who Is the ZED-24 Actually For?

This is where honest assessment matters more than marketing hype. The ZED-24 excels in specific scenarios and isn't the right choice for others. Let's break it down clearly.

Ideal Users

• Small to medium venue owners — Pubs, clubs, cafés, and function spaces running regular live music with bands of 5-8 members. The channel count handles a typical rock or covers band setup comfortably, and the audio quality is a genuine step up from budget mixers.
• Churches and community organisations — Worship teams with multiple vocalists, instruments, and playback requirements. The straightforward analogue layout means volunteers can learn to operate it without extensive training.
• Schools and educational institutions — Drama productions, assemblies, and music programs benefit from the reliability and simplicity of analogue operation combined with professional sound quality.
• Rehearsal studios — The USB recording capability combined with generous channel count makes it perfect for capturing rehearsals and developing mixes.
• Project studios supplementing a DAW — Engineers who want a high-quality analogue front end for tracking, with the ability to sum and monitor through a proper console.
• Mobile DJs and event operators — Those running corporate events, weddings, and functions where multiple mic and music sources need professional mixing.

Probably Not the Right Fit If...

• You need multitrack recording — The stereo USB won't capture individual channels. Look at digital consoles like the Allen & Heath Qu series or a separate multichannel interface.
• You need extensive monitor mixes — Two pre-fade aux sends cover basic monitoring, but larger bands wanting individual in-ear mixes need more aux buses.
• You need scene recall and presets — As an analogue desk, every setting is manual. If you switch between multiple acts regularly and need instant recall, digital is the way to go.
• You need built-in effects — Unlike the ZED-16FX and ZED-22FX, the ZED-24 doesn't include onboard effects. You'll need external processors or pedals for reverb and delay.
• You need remote control — There's no wireless mixing app here. If iPad control from the stage is essential, digital mixers are your path.

How the ZED-24 Compares to Alternatives

Context matters when choosing a mixer, so let's look at where the ZED-24 sits relative to common alternatives Australian buyers consider.

Feature	Allen & Heath ZED-24	Yamaha MG24XU	Mackie ProFX22v3
Mono Channels	16	16	16
Stereo Channels	4	4	3
Preamp Quality	DuoPre (excellent)	D-PRE (very good)	Onyx (very good)
EQ Bands (Mono)	4-band, 2 swept mids	3-band, 1 swept mid	3-band, 1 swept mid
Aux Sends	4	6	4
Built-in Effects	No	Yes (SPX)	Yes (GigFX)
USB Interface	Stereo	Stereo	Stereo (24-bit)
Build Quality	Excellent	Very Good	Good

The ZED-24's key advantages are its superior EQ section (two swept mids versus one on competitors), its excellent DuoPre preamps, and Allen & Heath's renowned build quality. The trade-off is the lack of built-in effects — if onboard reverb and delay are important to you, the Yamaha and Mackie options include them. However, many experienced engineers prefer using quality external effects rather than relying on built-in processing, as standalone units typically sound better and offer more control.

It's also worth noting that the Yamaha MG24XU offers 6 aux sends compared to the ZED-24's 4 — a meaningful advantage if you need more monitor mixes. But EQ flexibility and preamp character are where many engineers feel the ZED-24 justifies its position.

Practical Tips for Getting the Best from the ZED-24

Gain Structure

Proper gain staging is critical with any analogue mixer. Start with all faders at unity (0dB mark), and use the PFL (Pre-Fade Listen) button on each channel while adjusting the gain knob. Aim to hit the nominal level on the meter with typical signal levels — this gives you headroom for peaks without introducing unnecessary noise. The DuoPre design is forgiving, but disciplined gain structure will always yield better results.

EQ Approach

A common mistake with the generous EQ section is over-processing. Start with everything flat, engage the high-pass filter on every channel that doesn't need sub-bass (that's most channels except kick drum and bass guitar), and then make subtractive cuts before adding any boost. The swept mids are your most powerful tools — use them to find and reduce problem frequencies rather than boosting everything.

Managing Without Built-in Effects

Since the ZED-24 lacks onboard effects, you'll want a dedicated reverb unit. Options range from affordable multi-effects processors like the TC Electronic M-One or Lexicon MX200 through to high-end units. Route via aux 3 or 4 (post-fade), and you'll have professional-quality effects that are arguably superior to what built-in mixer effects provide. Many experienced sound engineers actually prefer this approach as it gives them more control and better sound quality.

Specifications That Matter

• Frequency Response: 10Hz to 50kHz (+0/−1dB) — flat and extended
• THD+N: Less than 0.003% — exceptionally low distortion
• Mic Input EIN: −127dBu — very quiet preamps
• Channel EQ: 4-band with 2 swept mids (mono channels)
• Aux Sends: 4 (2 pre-fade, 2 post-fade)
• Main Outputs: Balanced XLR stereo, plus mono output
• USB: Stereo send/return at 16-bit/48kHz
• Phantom Power: 48V switchable
• Power Supply: Internal universal (no wall wart — a genuine plus for reliability)

The internal power supply deserves special mention. Many mixers in this class use external power adapters (wall warts), which are easy to lose, prone to interference, and generally less reliable. The ZED-24's internal PSU means one fewer thing to worry about at a gig — you just need a standard IEC power cable, the same type used by most pro audio gear.

Australian Buying Considerations

For Australian buyers, a few practical points are worth noting. The ZED-24 ships with a standard IEC power inlet and works on Australian 240V mains without any adapter or voltage converter needed. Allen & Heath products sold through authorised Australian dealers like MusiconStage come with full manufacturer warranty coverage valid in Australia.

Given Australia's climate — particularly in warmer states like Queensland and the Northern Territory — it's worth noting that the ZED-24's robust steel construction handles heat better than plastic-bodied alternatives. For outdoor events (common across Australian summers), the solid build quality provides extra peace of mind.

Availability is generally good through authorised dealers, though specific stock levels can fluctuate. If you're planning a purchase around a specific event or installation date, it's worth ordering with some lead time to avoid any supply delays.

Common Questions About the ZED-24

Can I use the ZED-24 for multitrack recording?

Not directly — the USB interface captures a stereo mix only. However, you can pair the ZED-24 with a separate multichannel audio interface connected to the direct outputs or insert points if multitrack recording is essential. Alternatively, consider the Allen & Heath Qu-24 if multitrack recording is a primary requirement.

Does it have built-in effects like reverb and delay?

No. Unlike the ZED-FX models (ZED-12FX, ZED-16FX, ZED-22FX), the ZED-24 does not include onboard effects. You'll need an external effects processor connected via the post-fade aux sends. Many engineers consider this an advantage, as dedicated effects units typically offer superior sound quality.

Is the ZED-24 suitable for a permanent installation?

Absolutely. Its reliable analogue design with internal power supply makes it well-suited for permanent installations in venues, churches, schools, and community centres. The straightforward operation means staff and volunteers can use it without extensive training.

How does it compare to moving up to a digital mixer?

The ZED-24 offers simplicity, reliability, and superior analogue sound quality at a lower price point than most capable digital consoles. Digital mixers add scene recall, built-in effects, remote control, and multitrack recording. If those features are essential, digital is the right move. If you value tactile, straightforward mixing with excellent audio quality, the ZED-24 is hard to beat.

Will it work with my Mac or PC for USB recording?

Yes. The USB interface is class-compliant on macOS and requires a standard driver on Windows. It works with virtually any DAW software including Logic Pro, GarageBand, Audacity, Ableton Live, and Reaper.

The Verdict: Who Should Buy the Allen & Heath ZED-24?

The Allen & Heath ZED-24 is a genuinely excellent analogue mixer for anyone who needs 24 channels of clean, professional-quality mixing without the learning curve and complexity of a digital console. Its strengths — outstanding DuoPre preamps, comprehensive 4-band EQ with swept mids, solid build quality, and practical USB recording — make it a standout in its category.

It's not trying to be everything to everyone. It doesn't have built-in effects, it won't do multitrack recording over USB, and it offers just four aux sends. But within its design brief, it executes brilliantly. The audio quality punches well above its price point, and the build quality means it'll still be performing years from now.

If you're running a small-to-medium venue, managing sound for a church or school, operating a rehearsal studio, or doing regular live gigs with bands that need solid channel count and genuinely good sound, the ZED-24 deserves serious consideration. It represents exactly what Allen & Heath do best — delivering professional audio performance in a practical, reliable package.
