Mic Gain
The Crimson 3 features two identical microphone preamps. The preamps are ‘discrete’,
which means they use single transistors instead of ICs, usually found in high-end pre-
amps. This allows the preamp to be perfectly optimized for its task.
Use the Mic Gain control to adjust the microphone preamp level. The adjustable gain
range spans from +7 to +60 dB. To achieve the best recording level, the -6 dB LED should
flash from time to time: you have enough headroom left. If the LED permanently remains
on, it means that the level is at the brink of overloading — in such cases, you should
reduce the Mic Gain value.
The OVL LED indicates that the Crimson 3’s AD-converter is overloading, which should
be strictly avoided.
IMPORTANT:
Line Input 1|2 has preference over Mic Input 1|2. If you cannot hear a microphone signal,
check whether a jack plug is inserted into Line 1 or 2.
