LIMITER 
Set DRIVE back close to 0, and engage the LIM IN, then adjust the LIM IN control to set the 
desired amount of limiting, and compensate with the LIM OUT control. Setting the LIM IN 
switch to the top SC HPF position engages the limiter with a hpf on the sidechain. Set the 
meter switch to LIM to show gain reduction on the meter. The limiter comes after the eq and 
DRIVE, and before the HARM circuits, so when it is engaged, DRIVE effects how hard the limiter 
is driven, and LIM OUT effects how hard HARM is driven. 
PARALLEL MIXING 
The PREAMP fader, which is essentially a dry signal (unless the GAIN is overdriven) allows the 
parallel mixing with the fully processed CHANNEL fader and the dry MIX fader.  The faders are 
additive so they may require balancing to maintain headroom. The preamp fader has an 
access point on the rear panel, and any other signal from the unit (EQ, or LIMITER for 
example) can be patched here. An external signal (effects, pedal, etc.) can also be patched 
here. 

*The Imperial Channel is as much an instrument as a classic channel. It has several gain stages 
that are collectively capable of massive amounts of gain. High and low frequency instability 
and noise are possible especially at high gain settings, extreme limiting, and LMF shelf boosts, 
so be aware to keep headphone and speaker levels in check at all times.
