Welcome to Ayre Your Ayre MX-R mono power amplifier offers a significant advance in the musical performance of high-fidelity equipment. 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 leve[...]

Connections and Installation The Ayre MX-R is easy to hook up and use. The following guidelines will ensure that the installation goes smoothly. Location Do not stack the Ayre MX-R directly with other components, as this may restrict the airflow or induce hum into the audio circuitry. A good location for your mono power amplifier is on the floor ne[...]

Input The MX-R mono power amplifier can be driven by a preamplifier or directly from a line-level source (e.g., D/A converter or CD player) that has a volume control. A balanced input connector is provided to achieve the highest sound quality. Should it be necessary to connect a single-ended preamplifier or source component, high-quality adapters a[...]

Loudspeaker Outputs The heavy-duty output terminals of the Ayre MX-R work best with speaker cables using spade lugs. The Ayre MX-R drives the loudspeakers with balanced outputs. Since neither of the loudspeaker output terminals are grounded, connecting them to ground may damage the amplifier. Do not connect the loudspeaker outputs to any speaker sw[...]

When connecting the linked components to form a chain, be careful not to connect the two ends of the chain. Closing the chain to form a loop will cause the AyreLink system not to function. If there are no other AyreLink components in your system, the MX-R amplifiers may also be controlled by a trigger output from another component. In this case, co[...]

Controls and Operation The Ayre MX-R has a front-panel button for conventional stand-alone operation. The amplifier may also may be controlled by other linked components via the AyreLink communication system. Alternatively the AyreLink port may be used to accept a trigger signal from another component, thereby controlling the amplifier’s operatin[...]

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, yet reduces the power consumption from 120 watts to 45 watts. AyreLink The AyreLink communication system provides integrated control functions for your audio system. Linked[...]

Turning on a linked power amplifier will also turn on all other linked power amplifiers. Standby A short press on the standby button of a linked component will turn that individual component off. A longer press (more than two seconds) will turn off all linked components. A long button press provides a simple way to turn the entire system off from a[...]

Customization and Configuration The MX-R power amplifier is configured from the factory for flexible operation in most audio systems. However, in certain installations it may be desirable to change the factory default settings or create an alternate control connection. Display Brightness Normally the brightness of the status LED is controlled by ot[...]

One press – Low brightness Two presses – Medium brightness Three presses – High brightness After the ten-second configuration period has elapsed, the status LED will revert to green (”Standby” mode). If no button presses are detected during the ten second period, the unit will revert to the factory default setting (high brightness). Chang[...]

Rear view of MX-R amplifier. An adapter cable must be fabricated to connect the trigger output of the control component to the AyreLink port of the MX-R amplifier. The easiest way to do this is to remove the modular (RJ-11) connector from one end of a two-line telephone line cord. (This is the type of cord that connects the telephone set to the wal[...]

During level-sensitive operation, applying a voltage to the trigger input will set the amplifier to the “Operate” mode. When the applied voltage drops to zero, the unit reverts to “Standby”. In the pulse-sensitive mode, a positive-going pulse will toggle the amplifier between the “Standby” and “Operate” states, duplicating the actio[...]

15 In Case of Trouble The Ayre MX-R provides comprehensive protection for both the amplifier and your loudspeakers, including faults that may occur in your source components. Overheating A sensor located on the audio module will shut the amplifier off if the chassis temperature reaches 155° F (70° C). If the unit is operated at high playback leve[...]

the amplifier has cooled will be displayed on the front panel of the preamplifier. To restore the unit to the blue “Operate” mode, simply press the front-panel button. If the amplifier is linked to an AyreLink-equipped preamplifier with an alpha-numeric display, restoring operation of the amplifier will clear any messages displayed on the front[...]

If the amplifier is linked to an AyreLink-equipped preamplifier with an alpha-numeric display, restoring operation of the amplifier will clear any messages displayed on the front panel of the preamplifier. (Messages may also be cleared by placing the preamplifier in “Standby”.) AC Line Voltage If the AC line voltage drops below 75% of normal (b[...]

If the amplifier is linked to an AyreLink-equipped preamplifier with an alpha-numeric display, restoring operation of the amplifier will clear any messages displayed on the front panel of the preamplifier. (Messages may also be cleared by placing the preamplifier in “Standby”.) DC Offset The Ayre MX-R incorporates a circuit to detect the presen[...]

After correcting the suspected fault condition, a press of the front-panel button is required to return the unit to the green “Standby” condition. If the amplifier is linked to an AyreLink-equipped preamplifier with an alpha-numeric display, a message indicating that the proper amplifier operation has been restored will be displayed on the fron[...]

playback levels. The amplifier will automatically revert to “Standby” (green) when it has cooled. Be sure to correct the problem before continuing to use the amplifier. Red DC Offset – Excessive DC offset is present at the amplifier output. If there are any unusual noises coming from the loudspeaker, immediately disconnect the amplifier from [...]
