1. Power Switch

5. DSP Control

Press the power switch in to turn on the amplifier. As a general rule, turn it on after your preamplifier or receiver is turned on. When you have finished listening for the night, turn it off before your preamplifier or receiver are turned off. These precautions will help prevent turn-on and turn-off thumps in the subwoofer.

After a period with no input signal, the amplifier will automatically turn itself to standby mode, where it is effectively off. It can however, turn back on auto- matically when an audio input signal is present, or if a 12 VDC trigger voltage is applied to the Trigger inputs.

2. IR Receiver

The area in front of this IR Receiver window should be kept clear and unob- structed, so the amplifier can receive IR commands from the remote control.

3. Power LED

This LED will turn blue when the ampli- fier is on, and red when it is in standby mode.

4. DSP Display

This vacuum fluorescent display (VFD) shows the status of the amplifier's controls. Multiple menus allow full con- trol of the amplifier's parameters and performance.

This control allows selection and ad- justment of the amplifier's parameters. It can be turned clockwise, counter- clockwise, and pressed-in to navigate through the DSP menus.

Turning the control counterclockwise will move the display backwards through its menus, and allow values to be decreased.

Turning the control clockwise will move the display forwards through the avail- able menus, and allow values to be increased.

Pressing the control in will allow the selection of a parameter.

6. Rack Ears

The amplifier comes with two rack ears that allow it to be mounted in a standard 19 inch rack.

Allow one rack space for the amplifier, and one rack space minimum above and one below it for ventilation.

The rack ears are easily removed using three existing screws as shown.
