Manual abstract: user guide MYRYAD MXA2080
Detailed instructions for use are in the User's Guide.
[. . . ] 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. If the amplifier is moved shortly after operation take care not to touch the heatsinks, which are accessible from below, as they may be very hot. [. . . ] A second cable can then run from the MYLINK OUT socket on the MXA2080 to the MY-LINK IN socket on a third Myryad component (if desired) and so on in "daisy-chain" fashion. Inexpensive interconnects may be used as the My-Link bus carries only control signals, not audio, so these cables have no effect on sound quality. Please note: · Manually switching the MXA2080 into standby will not switch other My-Linked units into standby. · When the My-Link is connected it is recommended that no connection be made to the REMOTE TRIGGER input (see below). Line inputs The line inputs can be driven from the line outputs of any good quality preamplifier (such as the Myryad MXP2000) or any other suitable line level source. 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. 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.

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

IF YOU ARE IN ANY DOUBT ABOUT MEETING ANY OF THESE CRITERIA, OR PREPARING A SUITABLE LEAD, ASK YOUR DEALER OR INSTALLER TO HANDLE THIS FOR YOU.
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. [. . . ] If the problem persists return unit to approved Service Agent.

TROUBLESHOOTING GUIDE
Some of the most common problems: No sound from any channel: · · · Power turned off or system in standby mode. Check and replace if necessary.
·
·
Loudspeaker cable pulled loose. Protection relay has operated because of a short circuit loudspeaker wire or amplifier overheating (see Fault Condition Indication on Page 6). 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. [. . . ]
