5.5 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 XTi2.5 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:
2. Connect signal source to Channel 1 and Channel 2 using XLR connectors (the amplifier inputs will automatically be
summed together when selecting this preset).
3. 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.
