1 -
Power LED - Indicates the power state, no color - off, red - standby mode, blue - on.
2 -
Master Volume - Controls the overall volume of the sats and subs together.
3 -
Sub Volume - Used to set the relative level of the subwoofer volume to the sat volumes.
At MAX there is about +12dB more gain available over the sat levels, but this will vary
based on the efficiency of the sats and subs used.
4 -
Sub Crossover - set the crossover point for the subwoofer between 40Hz and 150Hz. 80Hz
is marked as a reference.
5 -
Sat Crossover - sets the crossover point for the sats. Turned all the way to the left, there is
a switch position which defeats the crossover and runs the sats full range. Once the con-
trol is rotated towards the 40Hz position, the crossover will be switched in and provides a
range of 40Hz to 150Hz. 80Hz is marked as a reference.
6 -
45Hz Boost switch - allows the addition of +4dB of bass boost for the subwoofer.
7 -
Phase switch - switches the polarity of the subwoofer to allow better matching to the
sats in certain situations - the setting depends on the specific installation and James
recommends you start in the 0 degree setting.
8 -
Rack ears - for rack mounting the amplifier - these can be removed if needed for shelf
mounting.
