Avalon Design VT-737sp Direct Recording Channel

Avalon VT-737SP - single-channel Class-A tube dynamic processor that combines a tube microphone preamplifier, an instrument DI, an opto-compressor, and a 4-band parametric EQ.

Features:

• Vacuum triode tube signal path
• Microphone preamplifier with +48V phantom power
• Instrument DI with front panel connector
• High-gain switch increases the gain amount of the preamplifier
• Complete dynamic control from soft compression to hard-knee limiting, adjustable via threshold, ratio-compression, attack, and release controls
• Special spectral control including de-esser available via dual sweep mid EQ to side-chain switch
• Selectable discrete Class-A equalizer between Pre/Post compressor
• High and low frequency bands providing characteristics of a fully passive design
• Dual mid bands include variable frequencies and switched Q-width selection
• Extended mid frequency range in high and low bands using 10 frequency multipliers
• Output level control provides variable control over the entire signal path
• Large display VU meter for monitoring output level and compressor gain reduction
• Selectable power supply
