    This level of performance has been implemented using the highest level of workmanship and materials. You can be assured that the Ayre MX-R will provide you a lifetime of musical enjoyment.

  • Page 4: Installation

    Installation The Ayre MX-R is easy to hook up and use. The following guidelines will ensure that the installation goes smoothly. Location A good location for your mono power amplifier is on the floor near your loudspeaker, in an open-backed cabinet, or on a shelf.
  • Page 5 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 are available from your Ayre dealer.

  • Page 6: Loudspeaker Outputs

    The AyreLink communication system provides a convenient way to control your audio system. There are two AyreLink ports on the rear panel of the MX-R amplifier. Each port has four contacts and contains both an input and an output. Both ports function identically and may be used interchangeably.
  • Page 7 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, connect the AyreLink ports of your amplifiers in daisy-chain fashion as described above.

  • Page 8: Operation

    Status LED and Standby Button Green = Standby Blue = Operate 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 operating state.
  • Page 9 The AyreLink system transmits the “Operate” command sequentially with a brief delay between components, avoiding overload of the AC power supply. 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.

    LED of the MX-R amplifier. There is no directly accessible brightness control for the status LED on the MX-R. However if there are no other linked components available to adjust the brightness, a special configuration mode allows the desired brightness level to be selected.
  • Page 11 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...

  • Page 12: Trigger Control

    A trigger control allows one component to control the “Standby” state of another component. If there are no other AyreLink components to control the operation of the MX-R amplifier, it may be convenient to use the trigger control from another component.
  • Page 13 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.
  • Page 14 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 action of the front-panel button.

    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 panel of the preamplifier.

  • Page 18: Ac Line Voltage

    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 (brown-out),...
  • Page 19 “Standby”.) DC Offset The Ayre MX-R incorporates a circuit to detect the presence of DC at the output terminals which could be harmful to the loudspeaker. In this situation, the status LED glows red and the amplifier will not operate.
  • Page 20 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 front panel of the preamplifier.
  • Page 21 Flashing Red Flashing Violet 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. DC Offset – Excessive DC offset is present at the amplifier output.

  • Page 22: Warranty Statement

    Please take a moment to fill out and return the enclosed warranty registration card. Warranty Your Ayre MX-R power amplifier is warranted against defects in workmanship and materials for a period of five years from the date of purchase.
