4. Front Panel 1. Rack Mounting Ears Two front panel mounting holes are provided on each mounting ear. 2. Fan Outlet Grills ELXA Series amplifiers are cooled by two rear-mounted fans. Cool air flows over the heat sinks and exhausts through the back grills. Make sure these outlets remain clean to allow unrestricted air flow. -

5. Operation 5.1. Connecting Power ELXA Series amplifier power requirements are rated at: a) „idle“ b) 1/8th power („typical“ music conditions) c) 1/3rd power („continuous“ music conditions) d) Maximum rated power (circuit breaker limited) The maximum power current draw rating is limited only by the front panel circuit breaker. Consult the specification in the Appendices section for figures on the current that each amplifier will demand. -
Page 9: Connecting Outputs
amplifiers are configured with “Pin 3 hot”). The unused connector can be used to jumper the audio input to another amplifier input. 5.4. Connecting Outputs Speakers are connected using 5-way Output Binding Post or Speakon connector, depending on version supplied. Please note that on the 5-way Output Binding Post version of the ELXA, two pairs of 5-way binding posts are provided for each channel, so that paralleling of speakers is possible. -

6.6. Bridged Mono Mode Connections 7. LX Clip Limitting At the amplifier’s full power limit, or clipping point, LX will be activated. This is indicated by an illumination of the Limiter LED. The channel gain is automatically reduced, protecting the loudspeakers from potential damage from the high power, continuous square waves that would otherwise be produced. -
Page 12: Lrs Short Circuit Protection
LRS Short Circuit Protection If an output is shorted (i.e. defective speakers or crossed speaker wires) the LRS will automatically protect the amplifier. The load will be disconnected by the thermal protection circuitry (output relay opens) and the amplifier will be shut down. Please remove the short circuit and switch on the amplifier again to restart the amplifier. -
