NOTE:
wire the audio output, do the following steps:
To
1. Strip and insert the speaker wires into the
connector, making sure to observe correct polarity,
and tighten the captive screws.
2. Insert the wired connector into the amplifier
output, and secure the plug by tightening the
screws on either side, as shown to the right.

Remote Volume Control Port

The XPA U 3502 provides remote volume ports for Channels 1 and 2; each port
independently controls the volume for their respective channels. The upper port controls
Channel 2 and the first three pins of the lower port
controls Channel 1. Both ports use a 3-pin captive
screw plug for volume control on the V, C, and G
pins; the lower port also includes a 2-pin captive
screw connector for standby on the STANDBY and
G pins (see
for more information).
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), as shown
in the image to the right.
Options for remote volume control include the Extron
VCM 110 AAP, VCM 200 series, MLC 64 RS VC D, and Extron Control products with the
digital Remote Volume Control Port, such as the MLC 100 Plus and IPCP Pro 255 volume
controllers. For information on these devices, including part numbers, go to
com. Third-party 10k potentiometer volume controllers can also be used for remote volume
and mute control.
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 endom-
magé.
To avoid risk of damage to the amplifier or the speakers, always connect low
impedance speaker loads (8Ω/4Ω) to the appropriately marked output con-
nectors 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) aux
connecteurs de sortie correctement identifiés sur l'amplificateur.
You must use Class 2 wiring for this output to comply with UL requirements.
