POWER REQUIREMENTS
Power consumption for your model of the ES series amplifier is indicated on the rear panel for 1/8th output power.
Ensure that your mains voltage is the same as the rear panel mains voltage marker (+/- 10%).
MOUNTING
The ES Series amplifiers are one or two rack units high (1U) (2U) and will fit a standard EIA 19” or rack.
Typically amplifiers may be stacked directly on top of each other with no need for spacing between units, unless installed in high
ambient temperature environments where a single rack unit space between amplifiers will assist cooling further.
COOLING
The mixer amplifiers are cooled by axial fans which draw air inside the amplifier and expel the heated air outside the amplifier.
An unrestricted airflow into and out from the amplifier must be provided. Any restriction of the air flow will cause heat to build up within
the unit and possibly force the unit into its thermal shutdown mode.
If the amplifiers are to be operated in an environment where the airflow is restricted such as sealed racks, cooling should be
supplemented by extra cooling fans to evacuate the heated air and aid the flow of cool air through the unit.
OUTPUT WIRING
When wiring to your speakers always use the largest gauge wire your connector will accept. The longer the speaker lead the greater
the losses which will result in reduced power and less damping at the load. We recommend using a heavy duty, two core flex (four core
flex if bi-amping) 10 to 12 gauge (2mm2 to 2.5mm2 or 50/0.25 or equivalent) as a minimum.
SPEAKER OUTPUT
The output terminal strip accepts wire sizes from 16-22AWG (1.5mm2 – 0.35mm2) or spade lugs. The following table should be used
as a guideline for cable sizes. Regulations in your area may require different gauged wire and should be checked before using.
