Your Ayre V-1x offers a significant advance in the musical
performance of audio power amplifiers. The warmth and
immediacy of a live performance are apparent from the first
listening. The combination of superb resolution and a
natural, relaxed quality will draw you into the music, time
and time again. This level of performance has been
implemented using the highest level of workmanship and
materials. You can be assured that the Ayre V-1x will
provide you a lifetime of musical enjoyment.
Installation and
The Ayre V-1x is easy to hook up and use. The following
guidelines will ensure that the installation goes smoothly.
Do not stack the Ayre V-1x
directly with other components,
as this may restrict the air
flow or induce hum into the
audio circuitry.
The Ayre V-1x produces a moderate amount of heat during
It is important to maintain an adequate supply
of air flow to avoid overheating the amplifier .
Good locations for your amplifier are on the floor, or in an
open-backed cabinet or rack. If the amplifier is placed in a
cabinet, be sure to provide at least three inches (75 mm) of
air space on all sides of the amplifier.
The receiver for the infrared remote control is mounted
behind the bottom recess on the amplifier’s front panel.
Although the transmitter’s beam will reflect off of most
wall surfaces, a direct line of sight from the listening
position will ensure the maximum range. The beam will
also travel through glass if necessary.

The input selector switch for
one channel will be in the
“up” position, while the other
channel’s input selector switch
will be in the “down”
The power amplifier can be driven by a preamplifier or
directly from a source (tuner, CD player, etc.) that has a
level control. There are two sets of input connectors on the
rear panel of the Ayre V-1x. The RCA jacks 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.
Using the incorrect position on
the input selector switches will
not harm the equipment, and
the amplifier may even seem to
operate normally. However,
some sonic degradation occurs
in this situation.
Selecting “Unbal” connects the inverting input to ground
through an isolation resistor. Therefore, the incorrect
setting of this switch forces a balanced source to operate in
unbalanced mode. Conversely, if the selector is set to “Bal”
while using an unbalanced source, the unused inverting
input is susceptible to hum pick-up and radio-frequency
The heavy-duty output
terminals of the Ayre V-1x
are designed to work best with
spade lugs.
The Ayre V-1x drives the loudspeakers with balanced
outputs. Since none of the output terminals are grounded,
connecting any of them to ground may result in serious
damage to the amplifier.
Do not use any speaker switch-box, accessory,
or test equipment that has a common ground
connection for both channels.
There are two sets of output terminals per channel, making
it easier to bi-wire your speakers. These terminals are wired
in parallel, providing identical output signals.

The master power switch on
the rear panel also
incorporates a circuit breaker.
There are two power switches on the Ayre V-1x. The master
power switch on the rear panel is normally intended to be
left on. The front-panel switch selects between the
“Standby” and “Operate” modes.
The Ayre V-1x features a sophisticated power monitoring
system. When first plugged in to an AC power source, the
front panel indicator light will glow red for approximately
90 seconds. During this time, the unit is in “Warm-Up”
mode and the front-panel switch is inoperable.
The remote control can also be
used to select the “Standby”
and “Operate” modes.
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 “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 300 watts to 30

Should the AC line voltage drop below 80% of normal
(brown-out), the unit will revert to “Warm-Up” mode and
the indicator light will glow red. After the voltage returns
to normal, the initial warm-up cycle will begin again.
The Ayre V-1x also incorporates a sensor to detect the
presence of DC at the output terminals. In this case, the
amplifier reverts to “Warm-Up” mode, the indicator light
glows red, and power is immediately removed from the
output stage. If the fault is still present when the front
panel switch is pressed to “Operate” after the warm-up cycle
is completed, the unit will immediately revert to the
“Warm-Up” mode again.
Remote Control
The remote control included with the Ayre V-1x has four
buttons. The single button on the left side of the hand-held
transmitter will select the “Standby” and “Operate” modes
on the amplifier, duplicating the action of the front-panel
switch. The three buttons on the right side of the remote
control will operate an Ayre preamplifier.
100 to 500 hours of music
played through the system will
assure full break-in.
Page 6
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.
In Case of
Should the Ayre V-1x amplifier ever fail to operate, please
check the following:
Is the unit in the “Operate”
The rear switch is the master power switch, and is normally
intended to be left on. The front switch is the
Standby/Operate switch. To operate the amplifier, the front
panel indicator must be glowing blue.
Are all of the connections to
the amplifier secure?
Check to see that the input and speaker connections on the
rear of the V-1x are in place. Also, be sure that the amplifier
is connected to a working AC outlet.
Is the AC circuit breaker OK?
The power switch on the rear of the unit incorporates an AC
circuit breaker. In the case of an overload, the circuit
breaker automatically sets the switch to the “off” position.
To reset it, press the switch to the “on” position.
If the circuit breaker immediately resets itself to the “off”
position, do not attempt further repairs. There are no
user-serviceable parts in the Ayre V-1x. If the amplifier still
does not operate, bring the unit to your dealer for assistance.
Do not remove the amplifier cover. Hazardous
voltages may exist inside the unit.
