7 REMOTE BALANCED OUTPUTS
If the system being used in the remote zone is equipped with balanced
(sometimes called “differential”) inputs, it is best to use these balanced out-
puts on your PAV. A balanced signal from preamplifier to power amplifier
will offer the highest possible performance with the best immunity from
common-mode noise, such as electromagnetic interference (EMI) or radio
frequency interference (RFI). This characteristic immunity is particularly im-
portant when using long cable runs, as may be expected when sending a
signal to a remote location. The balanced output signal is made available by
way of precision male XLR connectors (requiring female XLRs on the PAV
end of the interconnecting cable).
The pin assignments of these XLR-type male outputs are:
1 2
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to your amplifier’s operating manual to verify that the pin assignments
of its input connectors correspond to the PAV. If not, wire the cable so that
the appropriate output pin connects to the equivalent input pin.
Connect the right-channel and left-channel balanced remote outputs of
the PAV to the appropriate balanced inputs of the remote system.
8 MAIN BALANCED OUTPUT
If the power amplifier being used to drive the Front Left and Front Right
speakers is equipped with balanced (sometimes called “differential”) inputs,
it is best to use the balanced main outputs on your PAV. A balanced signal
from preamplifier to power amplifier will offer the highest possible perfor-
mance with the best immunity from common-mode noise, such as radio
frequency interference (RFI). The balanced output signal is made available
by way of precision male XLR connectors (requiring female XLRs on the
preamplifier end of the interconnecting cable).
The pin assignments of these XLR-type male outputs are:
1 2
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to your power amplifier’s operating manual to verify that the pin as-
signments of its input connectors correspond to the PAV. If not, wire the
cable so that the appropriate output pin connects to the equivalent input
pin.
Connect the right-channel and left-channel balanced main outputs of the
PAV to the appropriate balanced inputs of the remote system.
9 SINGLE-ENDED MAIN OUTPUTS
Single-ended (“unbalanced”) outputs are provided for compatibility with a
wide range of associated components.
