On the main display window there is  a series of LED’s 
which light-up as power output is increased.  This is in-
tended as a guide only and provides an indication of how 
hard the system is working.

Remote Eye 

The  Infrared Eye in the shape of a small mouse is placed at a location desirable for line of sight 
and the jack plug inserted into the panel marked as “Remote”. 
 

RM1 

Provides for full remote control of all functions and enables the user to setup the entire listening 
sound stage without moving from the listening position.  Once settings are stored, and assuming 

it is then desirable to turn the

 so that only the cabinet is visible, then this can be 

achieved without compromising the remote function. The remote eye feature enables the

 to be placed out of sight once setup is complete with user presets easily selectable 

by pressing one of the P1 - 4 buttons.

 This function parameter setting allows adjustment of the roll off (crossover) from the LFE 

input received via the RCA line level connector. This parameter enables high frequencies to be 
filtered out above the displayed setting with a 24dB slope from sources connected to this input.  
Most but not all AV decoders offer an adjustable pre filtered output for the LFE content.  Offering 
this fully adjustable setting for the LFE crossover gives a more flexible use for this input and 
enables the user to make adjustments over a wider frequency band and result in better 
integration possibilities.  Selecting above 120hz results in the “LFE bypass” circuit option.  The 
LFE bypass circuit sets the crossover to 200hz and only gain is adjustable.  The adjustment 
range is from 20hz to 120hz & bypass, incremented in single digit steps.  This highly accurate roll 
off adjustment enables precise matching of crossovers when using a multiple subwoofer set-up. 

Hi

 This function parameter setting allows adjustment of the gain from the inputs received via the 

Speakon and RCA line level left and right connectors. This parameter enables adjustment of gain 
and thus sound pressure output produced in relation to the input from sources connected to 
these inputs.  The adjustment range is from –99 to 0 incremented in single dB digit steps.  This 
highly accurate gain adjustment enables precise matching of gains when using a multiple 
subwoofer set-up.
