T25 Tube Compressor API Select
8
5.3 IN/out Switch
The IN switch is a soft IN/out button that defeats the compression action silently, but allows the signal
to pass through the FET amplifier and tube circuitry.
IN: Toggle to switch compression IN or out
• Activates gain reduction when engaged
• Audio passes through T25 circuitry without gain reduction when disengaged
• Illuminates when engaged
5.4 Bypass Switch
The BYP (Bypass) switch is a relay hard-wired bypass that routes the signal directly from the INPUT
XLR to the OUTPUT XLR, without going through any electronics.
BYP (Bypass): Toggle to engage the hard-wire bypass
• Signal bypasses all T25 circuitry when engaged
• Illuminates when engaged
NOTE: When the T25 is powered off, BYP is engaged allowing audio to pass directly through the
device. This allows the T25 to be powered off when not in use in order to prolong tube life.
5.5 Stereo Link Switch
The channels 1 and 2 of the T25 Tube Compressor function can be linked together for stereo operation.
This will prevent “center-image shifting” caused by differing amounts of gain reduction on each channel
when compressing correlated stereo signals and mixes. Examples include stereo piano or guitar, drum
overheads, or any other audio recorded with a stereo array. The T25 can also be used as stereo mix
bus compressor when used in linked mode.
The controls on both channels must all be set exactly the same in order to achieve equal gain reduction
on both sides of a stereo program when the link is engaged.
LINK: Toggle to link channels 1 and 2 for stereo operation
• Activates side-chain summing before the RMS detectors
• Set controls on both channels identically for equal gain reduction
