Avalon VT747SP

The Avalon VT-747SP is a 2U rack-mounted stereo valve-powered Class A optical compressor and limiter, with EQ.

TEC Award nominee, the Avalon VT-747SP offers excellent value and great sound - all in stereo, too. Adding the warm tones of valve compression to your mix comes easily with the Avalon VT-747SP. You have full dynamic control over the content - with LF and HF control over your side chain input, too. The Avalon TSP system lets you route your signals either through the valves or the clean, crisp Class A solid state circuits. After the compressor section on the VT-747SP is the 6-band graphic EQ panel which can, of course, be switched pre- or post- compression as you need.

Easily readable and logically laid out, the VT-747SP makes stereo operation simple and straightforward. Avalon has turned its pursuit of audio excellence into a life's work and with the Avalon VT-747SP it doesn't matter whether you are mixing an album, running a concert PA or just want to improve the sound of your playlist when you DJ, the VT-747SP enables you to share that goal.
