2
Connections and
Installation
The Ayre AX-7e is easy to connect and use. The
following guidelines will ensure that the installation
goes smoothly.
Location
Be sure to provide at least
three inches (75 mm) of air
space above the unit.
A good location for your integrated amplifier is in
an open-backed cabinet or on a shelf. The AX-7e
produces a moderate amount of heat during use.
It is important to maintain an adequate
supply of air flow to avoid overheating.
The infrared beam of the
remote transmitter will also
travel through glass.
The receiver for the infrared remote control is
mounted behind the display lens on the front panel.
A direct line of sight from the listening position
will ensure the maximum range.
Inputs
The Ayre AX-7e offers two pairs of balanced inputs
and two pairs of unbalanced inputs. Balanced
connections are made via three-pin XLR connectors,
3
while unbalanced connections are made via RCA
connectors.
When you have a choice, a balanced connection
will offer slightly higher sound quality than an
unbalanced connection.
The FET switches used in the input selector
circuitry offer transparent, noise-free switching,
with no moving parts. Please be aware that they can
be overloaded if the output voltage from the source
component is too high.
Do not use a source component that has
an output level greater than 4 V rms
unbalanced, or 8 V rms balanced.
Using a source component with too great an output
level will cause distortion.
The input connectors on the
rear panel are labeled to
match the input selector
buttons.
In this modern era of diverse source components, it
has become impractical to pre-label the inputs with
the actual name of the source. Instead, the AX-7e
has simple icons that allow you to easily remember
the selector button associated with each source.
Tape Outputs
By connecting the “Tape Out” jacks on the rear of
the AX-7e to a recorder with analog inputs,
recordings may be made directly from the other
source components connected to your amplifier. The
tape outputs are switched on and off at the front
panel. Please refer to the section “Controls and
Operation” for further information.
4
If a recorder is not installed in
your system, the “Moon” input
performs exactly like the other
unbalanced inputs.
If you are connecting a recorder to your
system, be sure to connect its outputs to
the “Moon” input of the AX-7e.
This will prevent the undesired possibility of
creating a feedback loop when making a recording.
Loudspeaker Outputs
The heavy-duty output
terminals of the Ayre AX-7e
work best with speaker cables
using spade lugs.
The Ayre AX-7e 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 AX-7e 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.
Removing the AC power from
the unit will cause it to lose
its memorized settings and
revert to the default settings.
When the unit is first connected to AC power, the
input selector will default to “Star”, the volume will
be at “11”, the display will be “On”, and both the
mute and record output will be “Off”.
5
Controls and
Operation
The Ayre AX-7e integrated amplifier may be
controlled using either the front panel buttons or
the included remote control handset.
Remote Control
The supplied remote control handset can operate
both the AX-7e integrated amplifier as well as an
Ayre CD player. The controls to operate the CD
player are grouped towards the top of the handset,
while those for the integrated amplifier are grouped
towards the bottom.
The remote control handset uses 2 x AAA batteries,
which must be installed before use. Access to the
battery compartment is achieved by sliding the
cover on the rear of the unit.
Volume Control
The Ayre AX-7e’s exclusive volume control yields
superlative sonic performance. Field-Effect
Transistor (FET) switches combine with discrete
6
metal-film resistors to create a volume control with
crystal-clear transparency and no moving parts. The
volume control comprises 66 individual levels, each
with a step size of 1.0 dB allowing for precise
selection of the desired volume setting.
The volume level is changed by pressing the black
bar above the front-panel display. The remote
control may also be used to change the volume.
When the unit is first connected to AC power , the
volume level defaults to “11”, a relatively low
setting. After that, the current volume setting is
retained in memory when changing inputs or when
the unit is placed in “Standby”.
Mute
The mute button provides an easy way to
temporarily turn the volume of the AX-7e to “zero”.
The current volume control setting is retained in
memory and appears on the display. When the unit
is placed in “Standby”, the mute function is reset.
7
Input Source Selection
The input selector buttons are located at the right
side of the unit. Icons that match the connector
labels on the rear panel (Star, Planet, Comet, Moon)
are used to denote the inputs.
When the unit is first connected to an AC power
source, the “Star” input is selected by default. After
that, the current input selection is retained in
memory, even when the unit is placed in “Standby”.
The input selector utilizes sophisticated FET
switches. Both the signal and ground connections to
each source component are switched, so that any
un-selected components are completely disconnected
from the system. This avoids any problems with
undesired ground loops.
Tape Output
The “Tape Output” function
does not operate on the “Moon”
input. This avoids the
When the “Tape Output” button is pressed, the
indicator will light up and the signal from the
currently selected source component will be routed
to the “Tape Out” connectors. This allows a
recording to be made.
undesired possibility of
creating a feedback loop.
Turn the “Tape Output” off unless a recording is
being made. This will completely disconnect the
recorder from the AX-7e (including the ground
connection), avoiding the possibility of undesired
ground loops.
8
Display
The display of the AX-7e may be turned off, if
desired. A single blue light indicates that the
display is turned off. When further commands are
received, either from the front-panel buttons or the
remote control, the display will be activated for a
few seconds to confirm the command, and then turn
off automatically. Pressing the “Display” button
again will turn the display on.
Standby
The Ayre AX-7e is very energy-efficient, and only
consumes about as much power as a standard light
bulb when playing. If you wish to further reduce
power consumption when not playing music, the
unit may be placed in standby mode. In standby
mode, the output stage is turned off and usage of
electricity is minimized.
Processor Pass-Through
When using the Ayre AX-7e in a surround-sound
system for home theater, it is desirable to use the
“Processor Pass-Through” mode. This mode allows
your two-channel music sources to be routed
directly through the AX-7e, avoiding the sonic
degradation of most processors, and at the same time
allows the front two channels of the theater system
to integrate with the AX-7e with the touch of a
single button.
9
If you are using a surround-sound processor, connect
the front left and front right outputs of the processor
to one of the inputs on the AX-7e. Please note that
the AX-7e can accept either balanced or unbalanced
signals.
To activate the “Processor Pass-Through” mode for
that input, remove the AC power from the AX-7e
for at least 10 seconds. Then, while pressing the
input selector button corresponding to the chosen
surround-sound processor input, re-connect the AC
power.
The chosen input is now programmed for “Processor
Pass-Through” operation, disabling the now
redundant volume control of the AX-7e. When that
input is selected, the preamplifier section of the
AX-7e is set to unity gain (0 dB), and the volume is
controlled directly from the surround-sound
processor. The volume indicator of the AX-7e will
display “PP” to show that the “Processor
Pass-Through” mode has been selected for that
input.
10
To clear the “Processor Pass-Through” mode from
an input and restore normal operation, remove the
AC power from the AX-7e for at least 10 seconds.
Then, while pressing the “Mute” button, re-connect
the AC power.
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
printed circuit boards, wires, and capacitors, a
break-in period is necessary for the amplifier to
reach its full performance potential.
