This guide provides startup instructions for experienced, professional installers to set up and operate the XPA Ultra Series audio
power amplifiers. All references are to the XPA Ultra Series User Guide which can be found on www.extron.com.
Step 1 — Powering Down Equipment
Be sure that power to the amplifier is turned off first.
ATTENTION:
Adjust the audio level to = (full attenuation) prior to powering the amplifier in Step 7 on page 2.
Turn off all other equipment and disconnect the power cables. Verify that the amplifier is disconnected from the power source
before proceeding.
amplifier does not reach or exceed +122 °F (+50 °C). No more than four stacks of XPA Ultra amplifiers should be arranged one-
on-top-of-the-other in a rack without an open space between the stacks (see the figure to the right).
XPA Ultra amplifiers can also be arranged above or below another
non-XPA Ultra device. In this case, the environment around the amplifier should not reach or exceed +122 °F (+50 °C).
Step 2 — Captive Screw Audio Cable Wiring
Wire the source output to the amplifier 3.5 mm captive screw input connectors as shown in the following illustrations.

Step 3 — Speaker Wiring
Wire the speakers to the amplifier output using the included 4-pin, 5 mm captive screw connectors as shown below. Each port
has a screw flange to secure the plug to the connector.

ATTENTION:
• Do not tie channel output pins to each other or to ground. Doing so will short out the outputs, damage the amplifier, or
both.
• Ne pas lier les sorties 1 et 2 des canaux entre elles ou à la terre. Les sorties pourraient être court-circuitées et/ou
l'amplificateur pourrait être endommagé.
•
To avoid risk of damage to the amplifier or the speakers, always connect low-impedance speaker loads (8Ω/4Ω) and
high-impedance speaker loads (70V) to the appropriately marked output connectors on the amplifier.
• Pour éviter tout risque de détérioration de l'amplificateur ou des enceintes, connectez toujours les charges de l'enceinte
faible impédance (8Ω/4Ω) et les charges de l'enceinte haute impédance (70V) aux connecteurs de sortie correctement
identifiés sur l'amplificateur.
NOTE: You must use Class 2 wiring for this output to comply with UL requirements.
