Allen & Heath CQ-18T vs CQ-12T vs CQ-20B: Which Compact Digital Mixer Suits Your Setup 2025

Allen & Heath CQ-18T 18 Channel Touchscreen Digital Mixer

If you've been researching compact digital mixers for your venue, worship space, or mobile rig, you've probably noticed Allen & Heath's CQ series popping up everywhere. And for good reason—these mixers represent a genuine shift in what's possible at the mid-range price point.

The CQ-18T sits right in the middle of this lineup, and that positioning raises an important question: is it the sweet spot, or are you better served by stepping down to the CQ-12T or up to the CQ-20B? After examining these mixers across real-world applications, I'm going to break down exactly what each one offers and help you figure out which actually makes sense for your situation.

Understanding the CQ Series: What Makes These Mixers Different

Before diving into comparisons, it's worth understanding why the CQ series exists at all. Allen & Heath already had the Qu series (excellent but aging) and the SQ series (professional but pricey). The CQ line fills a specific gap: bringing genuinely professional audio quality and workflow to users who don't need 32 channels or extensive expansion options.

All three CQ mixers share the same core DNA:

XCVI FPGA core – the same processing architecture found in their flagship dLive systems
96kHz operation – double the sample rate of most competitors at this price
Built-in Wi-Fi – proper dual-band wireless, not an afterthought
Bluetooth audio streaming – for background music and playback
USB recording/playback – multitrack to your computer or stereo to SD card
Automatic Mic Mixer (AMM) – genuinely useful for conferences and worship

The differences come down to channel count, physical format, and whether you need that touchscreen on the mixer itself.

Allen & Heath CQ-18T: The Middle Ground

The CQ-18T is the model we're focusing on today, and it occupies an interesting position. With its 7-inch touchscreen and 18 input channels, it's designed for operators who want hands-on control without relying solely on an iPad or laptop.

CQ-18T Specifications at a Glance

Inputs: 16 mic/line inputs (6 mono + 2 stereo channels with individual preamps), plus stereo USB and Bluetooth
Outputs: 6 configurable outputs plus headphones
Faders: 6 motorised 60mm faders with layer switching
Screen: 7-inch capacitive touchscreen
Processing: 4-band PEQ, compressor, gate on every channel; 8 stereo FX engines
Recording: 18x18 USB audio interface at 96kHz; stereo SD card recording
Connectivity: Dual-band Wi-Fi, Bluetooth 5.0, Ethernet

What makes the 18T particularly appealing is that touchscreen. Unlike the rack-mount CQ-20B, you can walk up to this mixer and see exactly what's happening—no app required. For volunteer operators or situations where you need quick adjustments, that's genuinely valuable.

Audio Quality: Are They Actually Different?

Here's something that might surprise you: all three CQ mixers sound identical. They use the same XCVI processing core, the same preamp designs, and the same converters. The 96kHz sample rate isn't marketing fluff—it genuinely provides headroom and transient response that you can hear, particularly on drums and acoustic instruments.

The preamps themselves offer 60dB of gain with remarkably low noise. If you're coming from an analogue mixer or an older digital desk, you'll notice the difference immediately. There's a clarity and openness that makes mixing easier, not just "better sounding."

So audio quality shouldn't factor into your decision between these three. Pick based on channel count and workflow preferences.

Channel Count: How Much Do You Actually Need?

This is where most people get the decision wrong. They count their current inputs and buy accordingly, without considering:

Growth: Will you add instruments or speakers?
Flexibility: Do you occasionally host larger events?
Aux sends: More outputs mean more monitor mixes

CQ-12T: When 12 Channels Is Enough

The 12T makes sense for:

Solo performers or duos with backing tracks
Small acoustic acts (2-4 performers)
Podcast studios with up to 4 hosts plus sources
Small meeting rooms where simplicity matters
Backup mixer for larger rigs

Eight mic preamps handles: drums (kick, snare, overhead), bass DI, two guitars, and two vocals. That's a full small band. Add the stereo inputs for keys or backing tracks, and you're sorted.

CQ-18T: The Practical Middle Ground

The 18T opens up possibilities:

Full drum miking plus complete band
Worship teams with 4-6 vocalists plus instruments
Corporate events with multiple presenters and sources
Theatre productions with several cast mics plus playback
Recording studios wanting a compact interface with real mixing capability

Those extra preamps and the two additional outputs give you room to breathe. Running three or four monitor mixes becomes practical, not a compromise.

CQ-20B: When You Need the Inputs

The 20B is for situations where you're regularly using 12+ mic inputs:

Full band with complete drum miking and multiple vocalists
Larger worship teams
Conference setups with many speaking positions
Installed systems where rack mounting matters
Theatre with significant cast mic requirements

Touchscreen vs App Control: What's the Real Difference?

The CQ-20B relies entirely on the CQ-MixPad app (iOS, Android, Mac, Windows). There's no screen on the unit itself. For some users, this is actually preferable—you're mixing on a large tablet screen with full visibility. For others, it's a dealbreaker.

The CQ-12T and CQ-18T offer both options. You can use the built-in touchscreen for quick adjustments and the app when you want the bigger view. In practice, most users settle into a hybrid approach: setting up on the app, then using the physical faders and screen during the event.

When the Touchscreen Matters

Volunteer operators: Walking up to a mixer and seeing levels is intuitive
Quick adjustments: Grabbing a physical fader is faster than unlocking an iPad
Backup: If your tablet dies, the show continues
Training: Easier to teach when there's hardware to point at

When App-Only Works Better

Installed systems: The mixer lives in a rack; you operate from anywhere
Multiple operators: Several tablets can connect simultaneously
Remote mixing: Adjust from the stage, the audience, wherever
Screen size: A 12.9-inch iPad shows more than a 7-inch screen

Connectivity: Wi-Fi, Bluetooth, and USB Explained

All three CQ mixers include identical connectivity, which is genuinely impressive at this price point.

Built-in Wi-Fi

The dual-band Wi-Fi (2.4GHz and 5GHz) creates its own network or joins an existing one. In a typical venue, you'll create the mixer's own network to avoid congestion. The 5GHz band offers faster, more reliable control—use it whenever possible.

Up to 5 devices can connect simultaneously. This means your sound operator, monitor engineer, and performers can all have their own control access.

Bluetooth Audio

The Bluetooth 5.0 input streams audio from phones or tablets for background music, playback during breaks, or walk-in music. It's not designed for critical listening—there's inherent latency—but for ambient music, it's perfectly functional.

USB Audio Interface

This is where the CQ series punches well above its weight. The CQ-18T provides 18 channels in, 18 channels out at 96kHz. That's a professional-grade audio interface built into your mixer.

Use cases include:

Multitrack recording of your entire show
Virtual soundcheck (record a performance, replay it later for mixing practice)
DAW integration for studio work
Streaming with individual channel control

SD Card Recording

For simpler needs, the SD card slot records stereo or multitrack audio directly. No computer required. For archiving gigs or creating demos, this is brilliantly simple.

Processing Power: What You Get on Every Channel

Every input channel includes:

High-pass filter: 20Hz to 400Hz, essential for cleaning up mics
4-band parametric EQ: Fully sweepable with adjustable Q
Compressor: With sidechain filter and comprehensive controls
Gate: For drums and controlling bleed

The 8 stereo FX engines provide reverbs, delays, and modulation effects. These aren't afterthought effects—they're derived from Allen & Heath's professional processing and sound genuinely usable without external gear.

Automatic Mic Mixer (AMM)

The AMM feature deserves special mention. For spoken word applications—conferences, panel discussions, worship services with multiple readers—it automatically manages gain sharing between microphones. When someone speaks, their channel opens; when they stop, it closes. This reduces feedback risk and cleans up your mix significantly.

Real-World Applications: Which Mixer Wins?

Best for Small Venues and Solo Operators: CQ-12T

If you're running a small café, acoustic venue, or corporate meeting room, the CQ-12T delivers professional quality without overwhelming complexity. The smaller footprint matters in tight spaces, and 12 channels handles most small-venue scenarios comfortably.

Best for Worship and Mid-Size Venues: CQ-18T

The CQ-18T hits the sweet spot for worship applications and venues running 5-8 piece bands. You get enough channels for proper drum miking plus a full band, enough outputs for multiple monitor mixes, and that touchscreen makes training volunteers significantly easier. The Allen & Heath CQ-18T represents the best balance of capability and usability for most users.

Best for Installed Systems and Larger Productions: CQ-20B

When the mixer lives in a rack and operators work from tablets, the CQ-20B makes sense. The additional channels handle larger input counts, and the rack format integrates cleanly into permanent installations.

What About Competitors?

The CQ series doesn't exist in a vacuum. Here's how it compares to common alternatives:

Behringer X32 Producer / XR18

The Behringer options cost less, but the CQ series offers genuinely better preamps, 96kHz operation (vs 48kHz), and more refined processing. If budget is extremely tight, Behringer works. If audio quality matters, the CQ series justifies the premium.

Yamaha TF1 / TF-Rack

Yamaha's TF series is more expensive and larger. The TF1 offers more faders and a bigger screen, but you're paying significantly more. For users who don't need 32+ channels, the CQ series offers equivalent audio quality at a lower price point.

QSC TouchMix Series

The TouchMix-16 and TouchMix-30 Pro compete directly. They offer similar touchscreen control and channel counts. The differences come down to processing philosophy and brand preference. Both are excellent; audition if possible.

PreSonus StudioLive Series

PreSonus offers strong DAW integration and competitive pricing. The StudioLive 16R is worth considering if you're heavily invested in PreSonus software. The CQ series generally offers superior preamp quality and processing.

Making Your Decision: Key Questions

Before purchasing, answer these honestly:

How many mic inputs do you regularly use? Count your typical show, add two for unexpected needs.
Do you need hands-on control? If yes, eliminate the CQ-20B. If you prefer app control, the 20B saves money on the touchscreen.
How many monitor mixes do you need? The 12T's 4 outputs handle simpler setups; the 18T/20B's 6 outputs give more flexibility.
Is rack mounting essential? Only the CQ-20B fits cleanly into a rack.
What's your operator experience level? The touchscreen models are more intuitive for volunteers and occasional users.

Value Analysis: What You're Paying For

All three CQ mixers deliver exceptional value when you consider what's included:

Professional-grade preamps and processing
Built-in Wi-Fi (no dongle needed)
Multi-channel USB audio interface
SD card recording
Bluetooth streaming
Comprehensive processing on every channel
8 stereo FX engines

Buying these components separately would cost more than the mixer itself. The CQ series represents genuinely good value at Australian street prices.

Final Recommendation

For most Australian buyers—worship venues, small-to-medium live sound, corporate AV, recording studios wanting a compact interface—the CQ-18T represents the best overall choice. It balances channel count, physical control, and capability without the compromises of the smaller 12T or the app-only operation of the 20B.

The touchscreen matters more than you might expect. Having a visual reference and physical faders creates a more intuitive workflow, particularly when training others or making quick adjustments during an event.

If you're certain 12 channels will always be enough, the CQ-12T saves money without sacrificing audio quality. If you genuinely need 16+ mic preamps and prefer rack mounting, the CQ-20B delivers.
