Installation Note: S-video (Y/C) signals are more susceptible to degradation
over long wire runs. The quality of wire used makes a
significant difference, but regardless, it is generally
inadvisable to run S-video cables more than twenty feet (6
meters). Composite video signals tend to hold up better over
longer runs, especially when high quality 75
cable such as
Madrigal MDC-2 is used.
8 BALANCED MAIN OUTPUTS (L, C, R)
The pin assignments of these XLR-type male outputs conform to the inter-
national AES standard, and are as follows:
12
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal (inverting)
Connector ground lug: chassis ground
Refer to your power amplifiers operating manual to verify that the pin as-
signments of its input connectors correspond to the Audio Video Preampli-
fier. If not, wire the cable so that the appropriate output pin connects to the
equivalent input pin, or reverse the leads of both your speaker cables to re-
verse the reversal and restore correct polarity.
High quality single-ended outputs are also provided for compatibility with
power amplifiers lacking balanced inputs.
Connect the left-front, center and right-front outputs of the Audio Video
Preamplifier to the corresponding inputs on your power amplifier(s).
9 SINGLE-ENDED MAIN OUTPUTS (ALL CHANNELS)
The first six of these eight RCA connectors provide the main 5.1 channels
normally associated with a high quality multichannel system: the left-front,
center and right-front outputs of the AVP2 are duplicated here in single-
ended form (for compatibility with power amplifiers lacking any balanced
input capabilities), along with the left-surround, right-surround and
subwoofer channels. Connect these outputs to the corresponding power
amplifier channels.
In addition, two auxiliary output channels are provided, labelled aux 1
and aux 2. These channels are used for any of several applications such as
support for 7.1 channel systems (using either separate side and rear chan-
nels Dual Drive surrounds), or as additional subwoofer channels. Select
the best use for your particular system in the Setup Menu, according to
your speaker configuration.
10 REMOTE ZONE OUTPUTS
The AVP2 includes a second signal path (beyond the primary one used in
the main listening room) that can feed a remote zone, or a record path for
making recordings, or both. There is one limitation: the remote and record
outputs always contain the same signal.
