SSL - XLogic Alpha Channel Strip - Recording studio converter

The SSL XLogic Alpha Channel is a fairly traditionally set-out channel strip, comprising a mic/line/instrument front end with a three-band console-style equalizer, all packed in a stylish 1U rack case. The EQ is, in essence, a mono version of the three-band EQ used in the stereo channels on the G-series console, while the preamp is a slightly modified version of the VHD mic pre from the E-series Signature Channel.

At the end of the signal chain is what SSL refer to as a Lite Limiter, adjusted by means of a single control. A single Neutrik Combi connector handles the input options (unbalanced jack with 1MΩ impedance, or balanced XLR) while the analogue output is on a balanced jack rather than the more usual XLR, which makes it simpler to connect to a patchbay or typical audio interface. An analogue insert point is also furnished on a pair of quarter-inch jacks, and a couple of RCA phono sockets allow two units to be linked for precise stereo tracking. Both the send and main outputs have a low (40Ω) impedance, ensuring that the unit will be comfortable with any load and also capable of driving long cable lengths where necessary.

Two further RCA phono connectors handle S/PDIF in and out, so this unit can be used to feed a relatively inexpensive soundcard (provided, of course, that it has an S/PDIF input) and the recorded result won't be compromised by budget converters. By default, the Alpha Channel's internal clock runs at 44.1kHz, with a 24-bit converter resolution. However, if sync'ed to an external digital source, the unit will operate at sample rates in excess of 96kHz (32Khz to 108kHz).
