Featuring the same specs and features of the standard 7603 but with a British tinge thanks to Carnhill I/O transformers, the 7603 XMod from Chameleon Labs is a rackmounted mic / line / Hi-Z preamp, EQ, and DI box for studios. Sporting extremely low noise, excellent dynamics, and 100% discrete, Class-A circuitry with 3-band inductor-based EQ control, this unit is an ideal starting point for any input signal.
The 7603 XMod features fantastic audio specs thanks to new custom-wound input and output transformers with nickel laminations and bobbin assemblies. Combined with high-permeability Mu-Metal enclosures, this ensures your audio signals have absolutely minimal noise with maximum dynamics and bandwidth. Inputs include a front-panel Hi-Z input for passive or low-output instruments, an XLR mic input, and an XLR line input, with selectable 600 or 1200-ohm operation on the mic input. Controls include variable input gain, high- and low-frequency shelving EQ with mid-frequency boost/cut, output gain control, phase reversal, and selectable VU meter, just to name a few. A universal internal power supply ensures global power compatibility. And with a steel enclosure with aluminum front panel and milled aluminum knobs, the 7603 is built to last. The 7603 XMod is designed and built in North America.
The Model 7603 XMod is based on high audio performance design techniques. By employing classic circuit design, film capacitors, a mechanical gain selector, and custom-wound transformers, Chameleon Labs ensures that the Model 7603 will exhibit classic audio sound.
