using the highest levels of workmanship and  
materials. You can be assured that the Ayre  
CX-7eMP will provide you a lifetime of musical  
enjoyment.

Connections and  
Installation  
The Ayre CX-7eMP is easy to connect and use. The  
following guidelines will ensure that the installation  
goes smoothly.  
Location  
The infrared beam of the  
remote control will also travel  
through glass.  
A good location for your CD player is at an easily  
accessible height in an open-backed cabinet or on a  
shelf. 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. However, the  
infrared beam will also reflect off of most wall  
surfaces with a reduced range.

Analog Outputs  
It is not normally  
recommended to use both sets of  
analog outputs  
The Ayre CX-7eMP offers both balanced and  
single-ended outputs. Balanced connections are  
made via three-pin XLR connectors, while  
single-ended connections are made via RCA  
connectors.  
simultaneously.  
When you have a choice, a balanced connection  
will offer slightly higher sound quality than a  
single-ended connection.  
Digital Filter  
The digital filter of the Ayre CX-7eMP features two  
user-selectable algorithms. A selector switch is  
located on the rear panel. One algorithm produces  
greater accuracy in the time domain and is labeled  
“Listen”. The other algorithm produces greater  
accuracy in the frequency domain and is labeled  
“Measure”.  
It is recommended that the selector switch be set  
to the “Listen” position. However some listeners  
may prefer the additional high-frequency energy  
provided by the “Measure” position.  
Digital Output  
The Ayre CX-7eMP features a balanced AES/EBU  
digital audio output on the rear of the unit. This  
may be used when connecting to a digital recording  
unit or other device, such as an external  
digital-to-analog converter (DAC). A switch on the  
4
 
rear panel allows the digital audio output to be  
turned off when its use is not required.  
An adapter is available from Ayre should you  
need to connect the digital output to an S/PDIF  
input that uses an RCA connector.  
AC Power  
The CX-7eMP may be plugged directly into an  
unswitched wall outlet. Although proprietary RFI  
(radio-frequency interference) filtering is built into  
the CD player, in some situations an AC power-line  
filter (such as those offered by Ayre) may provide  
additional sonic benefits.

Controls and  
Operation  
The Ayre CX-7eMP CD player may be controlled  
using either the front panel buttons or the included  
remote control handset. Basic functions are available  
at both locations, while additional functions are  
available only at the remote control handset.  
Remote Control  
The supplied remote control handset can operate  
both the CX-7eMP CD player as well as an Ayre  
preamplifier or integrated amplifier. The controls to  
operate the CD player are grouped towards the top  
of the handset, while those for the preamplifier or  
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.  
6
 
Standby/Operate  
The “Standby/Operate” button toggles the unit  
between normal operation and standby mode. When  
in standby mode a green status LED is illuminated,  
and the critical internal circuitry remains powered.  
This ensures optimal sound quality with a  
minimum of warm-up time.  
If a disc is in the player when it is turned on, it will  
read the disc’s Table of Contents (ToC) and display  
the total disc time and total number of tracks  
Pressing either the “Open/Close” or the “Play”  
buttons will also bring the unit out of standby  
mode.  
Open/Close  
The “Open/Close” button opens and closes the CD  
drawer.  
An open drawer may also be closed with either  
the “Standby” or “Play” buttons.

The “Previous” button will back to the start of the  
current track. Additional presses will move to  
previous tracks.  
The “Previous” button on the front panel can  
activate two separate functions, depending on  
how long the button is pressed. A quick button  
press (less than about ½ second) will activate the  
“Previous” function. A longer button press will  
activate the “Reverse Scan” function.

Display  
The display of the Ayre CX-7eMP has a time section  
on the left, a track section in the center, and a status  
indicator section on the right. When the disc is  
stopped, the display will indicate the total disc time  
and the total number of tracks. When the disc is  
playing, the display will indicate the elapsed time in  
the current track and the track number being  
played.  
Normally all three sections are illuminated. Pressing  
the “Display” button once will change the time  
section to a “Time Remaining” mode that shows the  
time remaining in the current track.  
The right-most decimal point in the time display  
will illuminate to indicate that it is currently in the  
“Time Remaining” mode.  
Pressing the “Display” button again will turn off the  
time section of the display altogether. Pressing the  
“Display” button a third time will turn off all  
sections, except for a blue status LED that indicates  
the display is off.  
When the display is off, pressing any key will  
wake up the display for a few seconds. If the disc  
is playing, pressing “Play” will wake the display  
momentarily without affecting playback.  
Pressing the “Display” button once more will restore  
normal operation.

Additional Functions  
The following functions are available only via the  
remote control handset.  
Number Keys  
The number keys allow quick navigation to the  
desired point on the disc.  
To enter a number greater than “9”, simply press  
the desired number keys in order. For example,  
to enter “23”, first press “2” and then “3”.  
Pressing the number keys for the desired track will  
begin play of that track, even if the disc is stopped.  
Repeat  
Pressing the “Repeat” button scrolls through normal  
mode, “Repeat Disc” mode, and “Repeat Track”  
mode. The repeat modes are indicated by red LEDs  
on the right side of the display area.  
The “Repeat Disc” mode is indicated by an arrow  
in the shape of a loop. The “Repeat Track” mode  
is indicated by the looping arrow combined with  
the number “1”.  
The “Repeat” mode will be cleared when the disc is  
stopped, the drawer is opened, or the unit is placed  
in “Standby”.  
11  
 
Random  
Pressing the “Random” button will play the tracks  
on the disc in random order. Play will commence as  
soon as the “Random” button is pressed.  
The “Random” mode is indicated by a decimal  
point after the track number.  
When the “Random” mode is selected, a  
randomized play list is generated. The “Previous”  
and “Next” buttons will navigate through this  
randomized play list in the normal fashion.  
To exit the “Random” mode, press the “Random”  
button again. Pressing either the “Stop” button or  
the “Open/Close” button will also exit the  
“Random” mode.  
If the unit is played in both “Repeat Disc” and  
“Random” modes simultaneously, the same  
randomized play list will be repeated  
continuously. Exiting and entering the “Random”  
mode will generate a new randomized play list.  
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 CD player to  
reach its full sonic potential.  
12  
 
The upper section of the remote  
control supplied with the Ayre  
CX-7eMP is used to control  
the CD player functions.  
The lower section of the remote  
control (shown with  
greyed-out buttons) may be  
used to control an Ayre  
preamplifier or integrated  
amplifier.
