Stereo mode routes the signal from both the A and B inputs through a single 

series of DSP modules. Each DSP module processes both the A and B signals 

with identical, linked settings. The linked Delay and Limit parameters can be 

controlled from Stereo mode’s consolidated Channel A+B control window 

(which displays automatically when Stereo mode is selected).

Bi-Amp 1

Bi-Amp 1 mode splits the Channel A input signal in the XOver DSP module at 

a programmable frequency point, and then routes the resulting high and low 

frequency signals through a parallel chain of DSP modules with independent 

equalization, delay, and limiter settings. The Delay and Limit modules for the split 

high and low frequency signals can be linked and programmed with identical 

settings by clicking on the Channel Link button below the Mode window. In 

Bi-Amp 1 mode, Output A routes low frequencies to a low-range speaker, while 

Output B connects to a high-frequency transducer.

Bi-Amp 2

Bi-Amp 2 mode operates identically to Bi-Amp 1 mode, except that the signals 

are swapped between Outputs A and B (i.e., Output B handles low frequencies 

while Output A handles high frequencies). The swapped A and B output routing 

allows the user to quickly correct reversed high/low speaker connections without 

having to physically access the amplifier’s back panel and manually change the 

speaker connection.

Bridge

Bridge mode combines the signals from Inputs A and B into a blended mono 

signal and then routes the resulting mono signal through a single chain of 

DSP modules, leading to a combined mono output. The mono output signal is 

identical at Outputs A and B, and the amplifier responds to a single combined 

speaker load.

Delay/Peak Limiter

Channel Link

In Dual Mono, Bi-Amp 1, and Bi-Amp 2 modes, the Channel Link virtual button 

will appear just above the Delay and Peak Limiter controls. When you click on 

the Channel Link virtual button, the button will light up, and the Delay and Peak 

Limiter controls for both channels will display identical values.

Delay

The Delay function digitally slows the final signal output from the amplifier by a 

programmable amount (expressed as either distance or time). This signal delay helps 

prevent phase and synchronization problems caused by sound traveling through 

air over long distances, e.g., between speaker arrays separated by long distances or 

between a performance stage and distant sound reinforcement speakers.
The Delay controls also simultaneously display the amount of signal delay in 

milliseconds (ms), meters (m), and feet (ft), which can be useful if you already 

know the precise distance between speakers.

Programming signal delay

1.  Program the signal delay by using either of these two methods:
a)  Rotate the Delay virtual knob clockwise until you achieve a suitable amount 

of signal delay. The ms, m, and ft text boxes will each display equivalent 

values as you rotate the virtual knob.

b)  Type a delay value directly into one of the text boxes below the Delay virtual 

knob (ms, m, or ft, depending on your preference). The Delay virtual knob 

will rotate to a position matching the delay value you have entered.

2.  Choose between 0° and 180° phase either by clicking on the Phase virtual 

button or by clicking directly on 0° or 180° directly below the virtual button. 

When the Phase virtual button is engaged, the virtual button will light 

yellow and the indicator next to 180° will light up.

Peak Limiter

The Peak Limiter helps protect your speakers by preventing signal spikes at the 

amplifier's output stage.
The Peak Limiter controls include a dedicated virtual knob with matching 

numerical displays in dBfs (decibels relative to full scale), Vp (Voltage(peak)), 

as well as a rating in Watts, which appears only when you choose an Ohm setting 

from the Load pulldown menu.
The BEHRINGER Amp Remote software also allows you to see the amplifier's total 

output as a rating in Watts. This Watt rating allows you to connect speakers with 

lower power ratings and then adjust the limiter to match the speakers' maximum 

Watt rating.

Note:

 the Amp Remote software does not automatically detect or show the total 

speaker load connected to the amplifier.
Controls for Hold and Release times appear near the bottom of the window, each 

with a matching numerical display.

Programming the output limiter

1.  Program the output limiter by using either of these two methods:
a)  Rotate the Peak Limiter virtual knob counter-clockwise until you find an 

adequate limiter setting for your sound system. The dBfs (decibels relative 

to full scale) and Vp (Voltage [peak])  text boxes will each display equivalent 

values as you rotate the virtual knob. 

b)  Type a limiter value directly into one of the text boxes below the Peak 

Limiter virtual knob (dBfs or Vp). The Peak Limiter virtual knob will rotate to 

a position matching the delay value you have entered.

2.  Choose a Load value from the Load pulldown menu (none, 2, 4, 8, or 16 Ohms) 

that matches the total combined load of all speakers connected to the 

amplifier's outputs. If your combined speaker load in Ohms does not exactly 

match 2, 4, 8, or 16 Ohms, choose the next lower Ohm setting from the Load 

pulldown menu (i.e., if your total combined speaker load equals 4.25 Ohms, 

select the 4 Ohm setting). When you select a Load setting, an additional Watt 

rating for the limiter will appear above the Load pulldown menu.
