QUICK START GUIDE

AUDIO INPUTS

There are two audio inputs 

on balanced XLR connectors 

labelled TOP and SUB. These 

provide the audio input signal 

to the TOP amplifier and SUB 

amplifier respectively.

AUDIO THRU OUTPUTS

There are two audio THRU 

outputs on balanced 

XLR connectors that are 

connected in parallel to the 

audio inputs. These outputs 

are unprocessed and are 

not buffered. They may be 

used to daisy-chain multiple 

amplifier units.

MODE SWITCH

This switch toggles the 

amplifier between ‘INPUT Y’ 

and ‘DUAL’ input modes. 
In ‘INPUT Y’ mode, the 

amplifiers receive their Input 

ONLY from the connector 

labelled ‘TOP’. This signal 

drives both the SUB and TOP 

outputs.
In ‘DUAL’ mode, a separate 

signal is required at the input 

labelled ‘SUB’ to drive the 

subwoofer (SUB output).

for the tops labelled TOP A
