User manual MYRYAD MXA2080

[. . . ] · Use in a multi-room setup, possibly together with other MXA2080s, to deliver high-quality audio to a number of different rooms. INSTALLATION AND SAFETY This amplifier generates a significant amount of heat when operating and thus requires good ventilation. Do not place it on a rug or other soft surface into which it could sink, obstructing the air inlets in its underside. Do not allow papers or cloth to obstruct the ventilation grille in the top cover. The amplifier should not be installed in a built-in situation such as a bookcase or cabinet unless proper ventilation is provided. [. . . ] High quality RCA-to-RCA (phono-to-phono) interconnects should be used. Line outputs The line outputs are directly connected to the line inputs - without buffering. The line outputs allow power amplifiers to be "daisychained" so that more complex multiamplifier or multi-room systems may be built. Loudspeaker outputs Each channel is capable of driving any loudspeaker with a rated impedance of 4 ohms or greater. The loudspeaker terminals are high-current binding-posts, coded red and black. CAUTION: THE RED TERMINALS ARE MARKED WITH A HAZARD SYMBOL TO INDICATE THAT THEY CAN BE LIVE, READ ALL THE LOUDSPEAKER WIRING INSTRUCTIONS CAREFULLY. IT IS RECOMMENDED THAT READY-MADE LEADS BE USED WHERE POSSIBLE. For correct imaging it is important that the two loudspeakers are wired "in phase". To ensure correct phasing wire the black (-) terminal on the amplifier to the black or "-" terminal on the loudspeaker. The red (+) terminal on the amplifier should be wired to the red or "+" terminal on the loudspeaker. 3 7. Remote Trigger Control input/output If the MXA2080 is being used in a system without a Myryad preamplifier, processor or integrated equipped with My-Link, the REMOTE TRIGGER input may be used to allow the MXA2080 to be remotely switched into or out of STANDBY. If your preamplifier or processor has a TRIGGER output which delivers a DC trigger signal when the unit is switched on (or out of standby) then it can be linked to the MXA2080 to switch that out of/into standby also. A lead must be used which is fitted with a 3. 5mm mini-jack plug to connect to the MXA2080's REMOTE TRIGGER input socket. The lead must be wired according to the rules below Remote Trigger Control Details Connector to MXA2080 REMOTE TRIGGER input:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Note: If the TRIGGER input is active when the rear panel POWER switch is turned ON, then the amplifier will not power up into standby mode as usual. It will power up immediately into its "active" state - with its normal power-on mute delay (see FRONT PANEL CONTROLS, STANDBY below). The REMOTE TRIGGER output is wired directly to the input. [. . . ] Carefully check all wiring after switching amplifier POWER OFF. Allow amplifier to cool. Amplifier fails to respond to Smart My Link® remote commands from Myryad Preamplifier, Preamp-Processor or Integrated: · My-Link cable is loose or not connected. Check connections on all linked units. Loud buzz or hum: · · Interconnect cable pulled partially out of its socket. Defective interconnect cable. Incorrect operation - some functions not working: · Control processor latched. [. . . ]
