3.0 Overview
The T25 Tube Compressor provides a comprehensive suite of controls:
• ATTACK: Sets the time it takes the compressor to respond after levels rise above threshold
• RELEASE: Sets the time it takes the compressor to return to unity gain after levels fall below
threshold
• RATIO: Sets the amount of compression applied to levels above threshold
o Four fixed ratios: 2:1, 4:1, 8:1, and 20:1
• IN THRESH (Input/Threshold): Sets the input level/threshold
o Sets the level at which compression begins (threshold)
• Out MAKE-UP (Output/Make-up Gain): Sets the compressor output level/make-up gain
• D-S: Toggles to activate the de-esser function
o Accentuates compression of high-frequency content
• THRUST
®
: Toggles to activate the patented THRUST
®
filter circuit
o Reduces heavy low-frequency content in the detection path
• IN: Toggles to switch compression IN or out
• BYP (Bypass): Toggles to engage the hard-wire bypass
• LINK: Toggles to link channels 1 and 2 for stereo operation
• GR:10-segment LED gain reduction meter
• PEAK: +18dBu LED peak indicator
