Radial ProD2 Stereo Direct Box: Eclipse Transformers That Actually Deliver
Radial ProD2 Stereo Direct Box: Why Aussie Keyboardists Swear By It

So you're hunting for a stereo DI that won't let you down when it matters most? The Radial ProD2 has been a studio and stage staple for years. And there's a bloody good reason for that.
Here's the thing. Not all direct boxes are created equal. Some colour your signal in ways you don't want. Others introduce noise that'll drive your sound tech mental. But the ProD2? It just works. Quietly. Reliably. Every single time.
What Makes the ProD2 Different?
Let's cut straight to it. The Eclipse ETDB2 transformers are the real heroes here. Radial didn't just grab off-the-shelf components – they designed these transformers specifically for maximum signal integrity and smooth frequency response. You get that warm, musical character without the mud.
Why does this matter for keyboardists? Because your Nord, your Moog, your whatever-synth-you're-rocking – it deserves to hit the mixing desk exactly how it left your instrument. Clean. Full. No compromise.
Key Features That Actually Matter
- Dual-channel stereo design – perfect for stereo keyboards, synths, and drum machines
- Eclipse ETDB2 transformers – Radial's custom design for exceptional linearity
- -15dB pad switches – tame hot signals from active electronics
- Ground lift on each channel – eliminate hum and buzz independently
- Merge function – combine both channels to a single output when needed
- All-steel construction – this thing's built like a tank (and I reckon it'd survive one)

Who Should Actually Buy This?
Honestly? If you're gigging with stereo keyboards, this is pretty much the standard. Session players, touring musicians, worship teams – the ProD2 shows up on stages everywhere. And in studios? Heaps of engineers keep a pair permanently patched.
But here's where I'll be straight with you. If you're just running a mono synth through a bedroom setup, you probably don't need stereo. A single-channel DI would do the trick. The ProD2 shines when you're actually using both channels.
Real-World Applications
Think about this. You've got a digital piano sending stereo samples. Without a proper stereo DI, you're either collapsing to mono (losing all that spatial detail) or dealing with two mismatched DI boxes. Neither option's ideal, yeah?
The ProD2 keeps your stereo image intact while isolating your signal path from the venue's potentially dodgy earth. Ground loops? Sorted. RF interference from that sketchy lighting rig? Handled.
Eclipse Transformers: The Technical Bit
Look, I could go deep on transformer specs. But what you actually need to know is this – the ETDB2 design gives you extended low-frequency response without the typical trade-offs. Translation? Your sub-bass synth patches won't turn to mush.
The high end stays open too. Bright piano tones, shimmering pads, percussive attacks – they all come through with clarity. It's the kind of transparent performance you'd expect from gear costing significantly more.

Frequently Asked Questions
Does the ProD2 require phantom power or batteries?
Neither! It's a passive DI, so it just works. Plug in and go – no power source needed.
Can I use it for acoustic guitar pickups?
Absolutely. While it's optimised for keyboards, it'll handle any high-impedance source beautifully. Stereo acoustic setups with dual pickups? Perfect match.
What's the merge function for?
When you've only got one DI input available on the desk, merge combines both channels. Useful for when venues are light on inputs.
Is the rugged build actually necessary?
After you've seen a road case go tumbling? Yeah, you'll appreciate the tank-like construction. This gear gets thrown around more than you'd think.
Final Verdict: Should You Buy It?
Here's my honest take. The Radial ProD2 isn't the cheapest option out there. But it's the one professional keyboardists actually choose when their signal matters.
The Eclipse ETDB2 transformers deliver. The build quality's proven over thousands of gigs. And that ground lift on each channel independently? Absolute lifesaver in venues with electrical gremlins.
If you're serious about your keyboard sound – whether that's live performance or studio recording – the ProD2 is an investment that pays off every time you plug in.
