Solid State Logic XLogic Alpha Channel Overview

  • 1Description

The Solid State Logic Alpha Channel is a rackmount analog channel strip offering a single channel of microphone preamplification, equalization, dynamics processing, and analog-to-digital conversion for singers, producers, and engineers in homes, studios, and live stage applications. With up to 75 dB of gain and Variable Harmonic Drive, the Alpha Channel can deliver anything from clean and smooth tones for soft vocals to ragged and gritty distortion for pounding drums. Its XLR-1/4" combo jack accommodates mic-, line-, and instrument-level input signals.

Eliminate problematic rumble and proximity effect via the 40/80/120 Hz high-pass filter. Tonal sculpting is easily achieved with the Alpha Channel's 3-band EQ—the LF band works in shelf or bell mode, the MF band has a variable Q control, and the HF band is a dedicated shelving curve. Connect your favorite outboard processor such as a compressor to the 1/4" insert jacks, position it before or after the EQ at the push of a button, and even mix the dry send signal with the return.

Activate the intelligent auto limiter to avoid clipping through the integrated 24-bit / 192 kHz ADC, which sends digital signal to the S/PDIF output jack. A separate analog output is presented on a balanced 1/4" TRS socket. The Alpha Channel also features adjustable output gain, a -20 dB pad, a polarity switch, and selectable 48V phantom power. The Alpha Channel occupies 1 RU of rack space and includes a detachable power cable.
