4 Advanced Operation
Presets: A preset is a group of DSP and amplifier settings for a particular speaker. Turn an Encoder to view Presets 1 through 20. To recall a preset, press the Encoder, then press and hold the Encoder to confirm. For more information on presets, see Section 4.3.
The preset currently in use is displayed in the upper right corner.
(A)Active means that the amplifier is operating exactly according to that preset.
(M)Modified means that the amplifier is operating according to the preset but with some settings changed.
If a preset number is flashing, it is not in use.
In the example shown below,
•Preset 7 is in use (it’s in the upper right corner).
•The amplifier settings have been modified (M) since Preset 7 was loaded.
•The large “7” is not flashing, which means that Preset 7 is in use.
•Preset 7’s

In the example shown below, you turned down an Encoder knob two notches after load- ing Preset 7.
•Preset 7 is in use (it’s in the upper right corner).
•Preset 7 is active (A). That means the amplifier is operating exactly according to that preset.
•The large “5” is flashing because Preset 5 is not in use.

Output Mode: Press an Encoder knob to select DUAL or BRIDGE (Bridge Mono). You will be prompted to confirm your choice. Press and hold an Encoder knob to confirm your choice. DUAL is the default. The Bridge indicator on the front panel will illuminate when the amplifier is bridged.
Input Y: Press an Encoder knob to select STEREO or Input Y. You will be prompted to confirm your choice. Press and hold an Encoder knob to confirm your choice. When INPUT Y is enabled, Channel 1's input signal feeds both channels. STEREO is the default. (This screen will not display in Bridge Mono mode).
Me/You Amp Finder: Allows users to identify a specific amplifier in a large network of amplifiers without having to compare address infor- mation. Me/you can be turned on/off from software and/or the front panel. Press an Encoder knob to turn on the Me/You amp finder. When on, the
When you see this screen, press an Encoder knob to enter the Advanced Menu, described next. You can go to the Advanced Menu screen from the Attenuation screen by pressing
Menu/Exit > Prev > Prev.
Attenuator Limits: You can set the minimum attenuation from 0 dB to
NOTE: The attenuator setting must be below the attenuator limit that you are trying to set. For example, if the attenuator is set at
Attenuator Limits
Attenuator Link: Allows either attenuator (Encoder) to control both channels. Push an Encoder knob to select Independent or Linked. Once the attenuators are linked, any difference in channel attenuation will be maintained, and the word LINK appears on the Attenuation screen.
LED Meter Display Type: Press either encoder to make the

Bar Meter Display Type: You can select what the bar meters will display in the Attenuator Screen. Press an Encoder knob to select Attenuation, Input Levels, Output Levels, or Thermal %.
Attenuation is displayed as the length of the bar meters in the Atten- uation screen that appears on startup. Input Levels and Output Lev- els are displayed as both average and peak in the bar meters.
Thermal % indicates the amplifier temperature in percent, where 100% is the maximum allowable temperature. If Thermal % reaches 100%, the amplifier is out of thermal headroom and has shut down.

Clip Limiter: Limits the output signal to prevent excessive clip- ping. Press an Encoder knob to select ON or OFF for each channel. OFF is the default.
