OPTION DIP SWITCHES

AUTO POWER-DOWN
SWITCH 1

Down=ON=Auto Power-down function 
enabled,

 UP=OFF=Auto Power-down function 
disabled. This switch is used to override 
the Auto Power-down feature of the 
amplifi er and unconditionally force the 
amplifi er to the on state.

MONO/STEREO
SWITCH 2

Down=Stereo, Up=Mono. When in Mono 
mode, the Left and Right audio inputs are 
actively summed together and fed to both 
the Left and Right output channels. 

When in stereo mode, Left and Right 
inputs are independent. 

NOTE: The IT-A25-M70 mono version of 
the product requires this switch to be set to 
mono mode when using stereo sources.

When operating the IT-A25-S8 in bridged 
output mode, this switch should also be set 
to mono mode.

Up=Professional Audio input levels, 

Down=Consumer Audio input levels. 

When down, this switch provides an

When up, this switch accommodates 
the higher signal levels provided by 
professional AV mixers.

OUTPUT BOOST
SWITCH 4

Up= +12dB, 

Down= Unity. When up, this switch 
provides an additional 12 dB of gain to 
provide additional fl exibility.
