Operation Manual

Integrated Processing Features

Delay

There is up to 50msec of delay available in the signal processing for time aligning your speakers. The software 

allows you to enter the amount of delay needed in the form of seconds, feet, or meters and does the calculation 

for you.

PeakX Plus Limiter:

Feed-forward output limiter with user-adjustable attack, release and threshold (0.1 dB resolution), plus 
integrated feedback limiter to minimize amplifier clipping.

Advanced Thermal Control

In this section, you can tailor the fan speed to specific applications. You have the choice of the following modes:

•  Normal

•  Early

•  Full-Speed

The fan mode can be changed using the front panel buttons at start-up or in the software. The default mode is 

normal and should work fine for most applications. Early mode turns the fan on sooner at a “lower” temperature, 

and Full-speed mode turns the fan on full-speed full-time. Full-speed mode is not recommended for “dirty” 

environments.

Advanced Monitoring

This feature allows you to have software visibility of both the Power Supply Temperature and AC Line voltage. 

AC Line voltage is “derived” from the amplifier rail voltage and is an approximation of the AC line voltage. This 

allows you to monitor the health of your amplifiers and provides for troubleshooting.

Front Panel Lock-Out

To disable or lock the buttons from the front panel, hold the Prev and Next at the same time until the screen says 

“locked”. The rotary knobs (attenuators) will still operate. To unlock, hold Prev and Next until the screen says 

“unlocked”.

The front panel can also be locked out from the software as well from the main panel.  However once it is locked 

in the software, it can only be unlocked from the software. You cannot unlock from the front panel. 

The rotary 

knobs (attenuators) will still operate.
