A 7603 with UK Carnhill Transformers

The Chameleon Labs Carnhill 7603-XMod channel strip gives you Class A clean mic gain and British-sounding tone shaping at an intermediate price. This rackmountable unit makes a great front end for your vocals, kick drum, or bass guitar, and also adds real analog thump and shimmer to your previously recorded takes - great for working out of the box. The 7603-XMod is an update to Chameleon Labs' first-ever product, the 7602, and sounds better than ever thanks to discrete EQ op-amps, Carnhill UK input and output transformers, and a custom internal power supply (no wall wart) to keep this unit running at its peak.

Chameleon Labs 7603-XMod Microphone/Line Preamplifier at a Glance:
  • An update to the Chameleon Labs 7602
  • Inductor-based EQs provide musical tone shaping
  • MuMetal casing protects signals from interference
A update to the Chameleon Labs 7602

Pro and project studios have sung the Chameleon Labs 7602's praise since its release. This was one of the first affordable channel strips to bring the coveted 1073 pre/EQ sound to the masses. Chameleon Labs have made the 7602 even better in the all-new 7603-XMod channel strip. For starters, they gave the 7603-XMod its own proprietary internal power supply for solid performance without the wall wart. They've also upgraded this XMod with Carnhill input and output transformers for better grounding, richer mic gain, and a fuller-sounding DI. Finally, gain staging is even easier in the 7603-XMod thanks to a backlit VU meter with custom ballistics for a precision response.

Inductor-based EQs provide musical tone shaping

Sound professionals all over the world rely on inductor EQs from legends like Rupert Neve for their musical-sounding boosting. The 7603-XMod's 3-band inductor EQ section is intuitive to use and easy on the ears, letting you sweeten vocals and goose guitars instantly in the midst of any busy session with a distinctly British flavor. These three EQ modules each feature discrete op-amps true to their vintage designs. Additionally, an onboard highpass filter lets you tune out rumble and HVAC noise that can eat up your bandwidth. Tone purists here at Sweetwater applaud Chameleon Labs for giving the 7603-XMod an EQ in/out toggle for sonic versatility.

MuMetal casing protects signals from interference

The 7603-XMod has excellent shielding to keep interference from degrading your signal. The MuMetal chassis does a great job of keeping Wi-Fi, RFI, and other wireless signals from tarnishing a performance.

Chameleon Labs 7603-XMod Microphone/Line Preamplifier Features:
  • Identical to the 7603, but upgraded with UK Carnhill input and output transformers
  • Classic 1970s analog British sound
  • A musical front end for your mics, instruments, and DI signals
  • Class A mic preamp with +70dB of gain and low distortion
  • 3-band inductor EQ with discrete op-amps for powerful analog tone shaping
  • Highpass filter keeps unwanted rumble from muddying your mix
  • Proprietary power supply delivers solid performance without the wall wart
  • MuMetal chassis keeps out Wi-Fi, RFI, and other wireless signals
  • Color-coded milled aluminum knobs keep you organized
  • Mic/line, +48volt phantom, polarity, and EQ in/out toggles
  • Switchable 300/1200-ohm mic impedance provides the best sound for your dynamics and condensers
  • VU meter with custom ballistics delivers precision performance
The classic 1970s analog British sound at a competitive price: the Chameleon Labs 7603-XMod!

Killer Sonics, Flex EQ, Great Price!

Think of it as the preamp for Engineers who are self-confident enough to buy for sonic quality and don't rely on the big-name alternatives to attract clients. With the 7603 you get quality craftsmanship and sonic excellence at a lower price. Doesn't hurt that it's also darn sexy!

The 7603 is a workhorse in the studio. Great on Vocals, guitars, drums, you name it.
Tons of gain, flexible metering, and a musical EQ. 

I've owned a couple 7602mkII for 10 years and was stoked to add the 7603 (xmod) pres to my rack!

An absolute necessity!

If you are looking for an amazing, colorful pre amp, look no further than the 7603 XMod. This thing is an absolute beast! Wether your recording an acoustic guitar or vocals, the XMod will allow you to really dial in your tones. The 7603 is very well built, here in Washington, and no expenses were spared on the hardware. It is a solid hunk of metal, and is extremely durable. If you have the opportunity to add this piece of gear to your arsenal, don"t pass it up!

Returned it.

I own and love my chameleon labs 7721 compressor and that is why I decided to give this preamp a shot. These are now made in china and there seems to be no quality control. I received mine with a big spacing at the top and my microphone cable would get stuck in the input I would have to yank it out, you see how that could be a big problem over time. I returned it and I'm still in the market for a great preamp.
