XTRA Full Rack Power Amplifier Series • Operation 13
ATTENTION:
•
Do not tin the wire leads before installing into the connector.
Tinned wires are not as secure in the connector and could be pulled out.
They may also break after being bent several times.
• Ne pas étamer les conducteurs avant de les insérer dans le connecteur.
Les câbles étamés ne sont pas aussi bien fixés dans le connecteur et
pourraient être tirés.
Ils peuvent aussi se casser après avoir été pliés plusieurs fois.
NOTES:
•
The XPA 2004 allows for bridged output of

(BRIDGE A)

(BRIDGE B)
inputs 1 (Bridge A) and 3 (Bridge B) only.
Bridging effectively doubles the output
power of those inputs. Inputs 1 and 3 are
the active inputs when in bridged mode
while inputs 2 and 4 are ignored.
• The XPA 4002 allows for bridged output of input 1. Bridging
effectively doubles the output power of input 1 while input 2 is
ignored.

High pass filter toggle switch — (see
figure 10 starting on page 10) Use a small
screwdriver to toggle this recessed two-position
toggle switch that alternates between Off (no filtering)
and 80 Hz. The XPA 2002-70V, XPA 2002-100V, and
XPA 4002-70V have two switches, one for each
output channel. The XPA 2003C-70V and XPA
2003C-100V have one switch for the line distribution
output channel (channel 3). Setting the switch to
80 Hz prevents the saturation of the speaker input
transformers by low frequency signals. Saturation can
result in severe distortion of the speaker output
signal.
NOTE: It is recommended that the high pass filter be left in the On position unless
filtering is applied to the signal upstream of the amplifier.

Mono audio output connector — Wire the included 2-pole, 5 mm screw lock
captive screw connector, marked “+” and “-,” for mono audio (see steps 1 and 2 on
the following page). Output is designed to power 70 V (XPA 2002-70V, XPA 4002-70V
and XPA 2003C-70V) or 100 V (XPA 2002-100V and XPA 2003C-100V) line distribution
systems and is rated at 200 watts (400 watts, XPA 4002-70V).
ATTENTION:
• You must use Class 2 wiring for this output to comply with UL requirements.
• Vous devez utiliser un câblage de classe 2 pour cette sortie afin de respecter
les exigences de l’UL.
NOTE: You must use Class 2 wiring for this output to comply with UL requirements.
