Avalon VT-747SP

The Avalon VT-747SP Stereo Compresser. Vacuum-tube warmth and presence with solid-state flexibility. 

The Avalon VT-747SP 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 in 2 rackspaces. 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.

Features :

  • Stereo Class A 6-band discrete passive program EQ 
  • TSP twin signal path, vacuum tube bypass 
  • Low noise -92dB 
  • Fully balanced Class A input and DC coupled outputs 
  • Stereo dynamic 60dB high resolution output meters 
  • High-quality analog VU meter for gain reduction 
  • High headroom +36dB input before overload 
  • Spectral side-chain monitor for pre listen 
  • EQ pre-post selection for opto-compressor 
  • Sealed silver relays for all signal routing 
  • Internal discrete regulated power supplies
