Avalon VT-747SP Stereo Compressor EQ

The Avalon VT-747SP Stereo Compressor|EQ lets you choose between tube tone and the classic Class A discrete transistor sound. Ideal for high-performance DAW input signal conditioning, stereo bus compression-EQ, stereo keyboards, and analog mastering applications. This Avalon Compressor combines a stereo tube-discrete Class A opto-compressor with musical 6-band program EQ, L-R output level and gain reduction metering, and internal regulated power supplies. All in just 2 rackspaces.
