Selecting Speaker Type
CAUTION: Incorrectly setting the Speaker Type selector switches can
damage speakers. Verify settings before activating amplifiers.
1) Turn the amplifiers off.
2) Turn the XTD off.
3) Use the chart in the Appendix to determine the setting that matches
your speakers. If your speakers are not listed, please contact USL.
4) Use a small screwdriver to set the rotary switches to the matching
setting.
5) Set the Bypass Mode switches to match the speaker configuration,
two-or-three-way. Up (or ON) is two-way; Down (or OFF) is three-
way. All switches must be set the same way - either all Up or all
Down.
6) Turn the XTD Volume pots fully counter-clockwise.
7) Set the Cinema Processor equalizer (or room equalizer) to “flat” (no
gain or attenuation) for all channels.
Setting Input levels
1) Turn on the XTD (but not the amplifiers).
2) Use a Pink Noise generator or other 0dB reference signal in the
Cinema Processor.
3) Note: The XTD is designed to accept signal levels up to +26dB
(6.25V rms) with a 0dB reference of 300 mV rms.
