Custom Installation Compatibility (RX-Z9,
RX-V2500, RX-V1500, RX-V757, RX-V657 and
RX-V557)
• Multi-Zone Capabilities
These receivers have a variety of features that
allow flexible custom installation for enjoying
sound in two or three rooms (zones) of your
home. The RX-V2500 and RX-V1500 provide
audio output to Zones 2 and 3, and the
RX-V2500 offers video output (including
S-Video) for Zone 2 as well. The RX-Z9/
RX-V757/RX-V657/RX-V557 deliver audio output
to Zone 2. Zone 2 power amplifier assignability
and speaker terminals mean that Zone 2 can be
fully independent with its own 2-channel power,
while you still enjoy 5.1-channel sound in the
main room (except RX-V557).
• Convenient Control
A switch for selecting Main Zone or Zone 2
power is conveniently located on the front panel
(except RX-V1500). All five receivers provide a
remote control for Zone 2, and the RX-V2500
also offers Zone 2 and 3 volume control, mute
and input selection.
• Other Features
All six receivers include trigger output for
automatic powering of other components
(RX-Z9/RX-V2500 has two), remote control IR
code input and output (RX-Z9/RX-V2500 has
two), and an RS-232C interface for using a PC or
touch-screen controller to configure the receiver.
They also provide speaker A, B or A+B selection.
Subwoofer Crossover and Phase Selection
(RX-Z9, RX-V2500, RX-V1500, RX-V757,
RX-V657, RX-V557 and RX-V457)
Adjusting the balance between the subwoofer
and the other speakers can result in significantly
better sound quality. By selecting the proper
crossover frequency, the subwoofer can
compensate for the low-range deficiencies of the
other speakers. These receivers allow you to
select nine crossover frequencies: 40, 60, 80, 90,
100, 110, 120, 160 and 200 Hz. In addition
providing a wider choice than most other
receivers, the steps between 80 and 120 Hz are
only 10 Hz apart for more precise adjustment.
There may be cases where the low
frequency output from the front speakers
Since the surround back amplifiers are automati-
cally assigned, no physical re-wiring is necessary.
For example, while Zone 2 is switched off, the
Main Zone can enjoy 7.1 surround sound. When
Zone 2 is switched on, the Main Zone can still
enjoy 5.1 surround sound, plus Zone 2 can enjoy
stereo playback. No need for re-wiring!

overlaps with the higher end of the subwoofer
output, meaning that part of the frequency
range will be output by both the front speakers
and the subwoofer. This is not a problem as
long as the phases of the sound waves from
the two sources match, but if they are out of
phase, they will cancel each other out,
resulting in those frequencies being lost. In this
case, the phase switch can be used to
eliminate the problem(except RX-V1500).
Easy-Operation Learning-Capable
Control Unit with LCD Dispaly
(RX-V2500, RX-V1500 and
RX-V757)
The remote control can “learn” the
functions of other components, so
you can use it as a single remote
for the entire system. It can be
preset with control codes for TV,
DVD, VCR, CDR, and other
components. They also are all
controllable from the remote, and
Volume, Mute, Input Select controls
are available for each zone as well.
