 Amplifier Control

APRT!:

 

The following scenarios assume that 

the amplifier is connected to the Q-SYS Core via 
Q-LAN. 

 hen the amplifier is not connected 

to the Q-SYS  ore, it is in a Fault mode, and 

not operational unless previously configured 

for fail-over or standalone mode as part of a 

Q-SYS design. 

With the exception of the Power 

Switch, found on the rear panel, all of the 
following controls are on the front panel.

Refer to — Figure 13 for location of front-panel controls.

Off Mode   

•  Rear-panel power switch is off, the 

amplifier is not operable. 

Rhe power 

switch is the T  Iains disconnect.

•  The front-panel power button (1) is 

not illuminated.   

•  Turn the power switch to ON. The 

amplifier enters the mode in which it was 
when power was removed – Run, Mute All, or Standby.

Run Mode

•  From Standby or Mute All mode, press and 

release the power button on the front panel. 
The amplifier is in Run Mode.

•  The power button (1) is illuminated green.
•  The amplifier is fully operable; audio can pass.

Standby Mode

•  From Mute All or Run mode, press and hold 

the power button (1) on the front panel for 
approximately four seconds.

•  The power button illuminates solid red.
•  The amplifier is not operable; audio will not pass.

Mute All Mode 

•  From the Run Mode, quickly press and release the 

power button (1).

•  The power button flashes red, all output Mute buttons (2) are red.
•  The amplifier output is disabled, but the front panel is 

fully operable.

SEL Buttons (3) 

•  Channel gain can be adjusted from the Q-SYS 

Designer software or from the front panel of the amplifier.

•  Use the SEL button to select one or more than one 

channel to change gain settings. All selected channels 
will change at the same time. 

•  If two or more outputs are bridged or in parallel, pressing 

one button in the group selects all channels in that 
bridged or parallel group.

NEXT (4) and PREV (5) Buttons

•  Navigates forward and backwards 

through the screens.

ID Button (6)

•  Press this button to display a screen with the 

amplifier's network name. In addition, the ID buttons 
on the associated Q-SYS Amplifier component and 
the associated Q-SYS Configurator item flashes. Press 
again, or click one of the other ID buttons, to stop the 
flashing and exit the screen.

•  When prompted, press this button to change the 

amplifier configuration to match the configuration of the 
associated Q-SYS design.

Master Control Knob (7)

•  Adjusts the Gain for the selected channel or 

channels. At least one channel must be selected.

•  When one or more channels are selected, turn the Master 

Control knob to jump to the Gain screen. After a few 
seconds with no activity, it returns to the earlier screen.

•  If there is more than one channel selected, and the 

gains for those channels are different, the difference is 
maintained unless the gain is raised or lowered to the 
limits for both channels.
