Connections and
Installation
The Ayre V-6xe is easy to connect and use. The
following guidelines will ensure that the installation
goes smoothly.
Location
Do not stack the Ayre V-6xe
directly with other components,
as this may restrict the air
flow or induce hum into the
audio circuitry.
A good location for your power amplifier is on the
floor between your loudspeakers, or in an
open-backed cabinet, or on a shelf. The Ayre V-6xe
produces a moderate amount of heat during
operation. Be sure to provide at least three inches
(75 mm) of air space above the amplifier.
It is important to maintain an adequate
supply of air flow to avoid overheating
the amplifier.
Inputs
The Ayre V-6xe can be driven either by a
preamplifier or a surround-sound processor. There
are two sets of input connectors for each installed
channel on the rear panel of the Ayre V-6xe. The
3

RCA connectors accept signals from unbalanced
sources, while the XLR connectors are for balanced
sources. A small toggle switch near the input
connectors selects either the balanced or unbalanced
inputs.
When you have a choice, a balanced connection
will offer slightly higher sound quality than an
unbalanced connection.
Note that the input selector switch for some
channels will be in the “up” position, while the
input selector switch for other channels will be in
the “down” position.
Only one set of inputs (balanced or
unbalanced) may be connected at a
time.
Pass-Through Outputs
The pass-through output
connector is wired in parallel
with the input connector.
Each channel features a pass-through output,
supplied via an XLR connector. This allows
multiple channels to be driven with a single source
and is especially useful for subwoofers, passive bi- or
tri-amplification, or distributed sound systems.
Simply use a balanced cable to connect the
pass-through output of one channel to the XLR
input of another channel on the same amplifier, or of
another amplifier with true balanced inputs.
The pass-through output does
not convert unbalanced sources
to a true balanced signal.
If you wish to drive an unbalanced amplifier from
the pass-through outputs, you will need to use
XLR-to-RCA adapters at the pass-through outputs.
These are available from your Ayre dealer.

Loudspeaker Outputs
The heavy-duty output
terminals of the Ayre V-6xe
work best with speaker cables
using spade lugs.
The Ayre V-6xe drives the loudspeakers with
balanced outputs. Since none of the output
terminals are grounded, connecting any of them to
ground may result in damage to the amplifier.
Do not connect the loudspeaker
outputs to any speaker switch-box,
accessory, or test equipment that has a
common ground connection.
AC Power
The V-6xe may be plugged directly into an
unswitched wall outlet. Although proprietary RFI
(radio-frequency interference) filtering is built into
the amplifier, in some situations an AC power-line
filter (such as those offered by Ayre) may provide
additional sonic benefits.

Controls and
Operation
The Ayre V-6xe has a front panel control for normal
stand-alone operation. The amplifier may also be
controlled via a “trigger” input in a home-theater.
Power Switches
The master power switch on
the rear panel also
incorporates a circuit breaker
that acts as a resettable fuse.
There are two power switches on the Ayre V-6xe.
The master power switch on the rear panel is
normally intended to be left on at all times. The
front-panel switch selects between the “Standby”
and “Operate” modes.
When the master power switch is first turned on,
the front panel indicator light will glow red for
approximately one second. During this time, the
unit is in “Warm-Up” mode and the front-panel
switch is inoperable.
Red = Warm-Up
Green = Standby
Blue = Operate
After the circuitry has stabilized, the indicator light
will change to green, indicating that the unit is in
“Standby” mode and is ready for operation. When
the listener presses the front-panel switch, the unit
is in “Operate” mode and the indicator light glows
blue.

In the green “Standby” mode the output stage is
turned off, while the input circuitry remains
powered. This allows the unit to warm up quickly
for optimal sonic performance, while reducing the
power consumption from 60 watts per installed
channel to 20 watts.
Trigger Input
Use a 1/8" mini-phone plug
with a positive voltage of
between +5 and +12 VDC
at the tip to operate the trigger
input.
A trigger input is provided on the rear panel of the
V-6xe to allow for remote switching between the
green “Standby” and blue “Operate” modes. The
two trigger input jacks are wired in parallel. Either
jack can act as an input or a pass-through output to
allow for “daisy-chaining” of multiple devices.
The unit is shipped from the factory in the
level-sensitive mode, which is compatible with most
equipment. During level-sensitive operation,
applying a voltage to the trigger input will force the
amplifier to the “Operate” mode. In this state, the
front panel switch is inoperative. When the applied
voltage drops to zero, the unit reverts to “Standby”
and the front panel switch may be used to manually
control the unit.
Some equipment instead utilizes pulses as a trigger
signal. The V-6xe can also accommodate these units.
To change trigger modes, turn the rear panel switch
“Off” for about 30 seconds to discharge the internal
voltages. Then press and hold the front panel switch
while turning the rear panel switch “On”. The status
LED will rapidly flash red (about 10 Hz) to indicate
that the pulse-sensitive mode has been selected.
7

Repeating this procedure will revert the unit back
to the level-sensitive mode, as indicated by the
status LED slowly flashing red (about 1 Hz).
In the pulse-sensitive mode, a positive-going pulse
edge will toggle the amplifier between the
“Standby” and “Operate” states, duplicating the
action of the front-panel switch.
When using the trigger input, the front panel
switch is still operative. However, operating the
unit with the front panel switch may put the unit
out of “sync” with the control device. If this
should occur, simply press the front panel switch
again to restore “sync”.
Channel Configuration
Each channel of the V-6xe is a self-contained
module (except for the power supply). Additional
modules may easily be installed by your authorized
Ayre dealer.
The V-6xe will hold a maximum of six channels.
There are three independent power supplies
installed. One power supply feeds the two left-hand
slots, another feeds the two center slots, and another
feeds the two right-hand slots.
Break-In
100 to 500 hours of music
played through the system will
ensure full break-in.
Due to the manufacturing processes used for the
wires and capacitors, a break-in period is necessary
for the amplifier to reach its full sonic potential.
