XPA U 1004 SB and XPA U 2002 SB • Operation

WARNING:
AVERTISSEMENT :
• 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 (8 Ω/ 4 Ω) et
les charges de l’enceinte haute impédance (70 V) aux connecteurs de sortie
correctement identifiés sur l’amplificateur.
NOTE:
You must use Class 2 wiring for this output to comply with UL requirements.
To
wire the stereo audio output, do the
following steps:
1.
Strip and insert the speaker wires into the
connector and tighten the captive screws.
Make sure to observe correct polarity.
2.
Insert the wired connector into the amplifier output,
and secure the plug by tightening the screws on
either side..

— (see
on page 14) On the XPA U 1004 SB, connect a
3-pole, 3.5mm captive screw connector for remote volume control on channels three
and four. On both amplifiers, there is a 5-pole captive screw port. The bottom port use
a 3-pin captive screw plug for volume control of channels 1 and 2 on the V, C, and G
pins, and a 2-pin captive screw for standby on the STANDBY and G pins.
Remote Volume Control Port
Pins V, C, and G (1, 2, and 3) control
volume by varying the DC voltage from
0 V (full attenuation) to 10 V (maximum
volume) with full muting in effect when
pin C is connected to ground (pin G).
Do not tin the wires!
