Capture that classic SSL sound in your mixes!
The Solid State Logic X-Rack Microphone Amp Module is an angelically pure and versatile input section with a choice of three separate input amplifiers: Mic amp, front panel instrument input, or line input. Designed for transparency and versatility with a set of high and low-pass filters, phase reverse, and everything you need from a very classy workhorse.
Please note: The X-Rack XR621 Mic Amp Module works in conjunction with the XR622 XR Master Module.
