KEY POINTS:
Setting the Volume – To set up the system, the amplifier/receiver should be at the lowest
volume setting. The XSS speaker selector\volume control should be the highest volume
setting. Slowly adjust the amplifier/receiver to a level that is acceptable before any
clipping or distortion is heard. The clipping and distortion point is where the
amplifier/receiver is at its maximum performance. Any excessive usage beyond this point
will cause the system to be overworked and subject to shutting down.
Mark the Amplifier/Receiver Setting – To be sure the amplifier/receiver volume setting
is not adjusted after installation; use a label maker on the amplifier/receiver to note the
maximum volume setting and that no adjustments should be made.
Figure A: The arrow indicates the maximum volume setting.
Avoid Amplifiers/Receivers with only 8-Ohm Power Rating – Amplifiers that only list 8-
Ohm power ratings are subject to poor performance below 8-Ohms. Speakers will not
consistently present impedance at the manufacturer’s specification. It is strongly
suggested to use an amplifier/receiver that is flexible with speaker loads down to 4-
Ohms. Amplifiers/Receivers made in the 80’s and 90’s are typically not the best
performers. The XSS2400W/XSS26100W is compatible with all Xantech amplifiers
except the PA4100X.
Do not use Bridge-type Amplifiers (including internally bridged amplifiers) - The XSS
Speaker Selector\Volume Control is not recommended for bridge-type amplifiers. Using
a bridged amplifier with the XSS2400W/XSS26100W may seriously damage the
amplifier and speaker selector. If you are not sure your amplifier is bridged please contact
the manufacturer.
