Factory Preset #5: SUBSYNTH
Putting the amplifier in SUBSYNTH mode allows you to turn on the
SubHarmonic Synth feature for use with a subwoofer on both channels. The
inputs are automatically summed, a 90Hz 4th order (24dB/octave) filter is
enabled on both Channel 1 and Channel 2, and the SubHarmonic Synth feature
is turned on at +12dB level. The XTi2 Series amplifiers come pre-loaded with a
preset that makes it easy to configure the amplifier for this operation.
Before you get started ensure that you:
1. Connect signal source to Channel 1 and Channel 2 using XLR connectors
(the amplifier inputs will automatically be summed together when
selecting this preset).
2. Connector the speaker as shown.
a. Connect a speaker to each channel output using Speakon©, Banana
Plugs, or bare wire
Follow these quick steps to configure the amplifier for SUBSYNTH operation:
1. Push the "Set/Enter" button and you will see the word "Preset" flashing.
2. Push the "Set/Enter" button again to enter the list of presets in the amplifier.
3. Push the "Next/Down" or "PREV/UP" button until the screen displays "SUBSYNTH".
4. Push the "Set/Enter" button to confirm your selection.
5. The display will now read "SUBSYNTH" with the Y icon and XOV icon highlighted.

Ensure Proper Cooling

When using an equipment rack, mount units directly on top of each other. Close any
open spaces in rack with blank panels. DO NOT block front or rear air vents. The side
walls of the rack should be a minimum of two inches (5.1 cm) away from the amplifier
sides, and the back of the rack should be open.
CAUTION: Before you begin installing your amplifier, make sure
it is disconnected from the power source, with the power switch
in the "off" position and all level controls turned completely
down (counterclock wise).
