  • Page 8: Rf Emissions

    INSTALLATION EMC (RF Emissions) The high frequency resonant converters in the E Series amplifiers have been designed to have very low radio frequency (RF) emissions, which can cause interference with other equipment. In order for this to be optimised, the amplifier should be mounted in a metal rack enclosure, which should have a separate (technical) Earth.

  • Page 9: General Information

    These systems can handle very high transient signals which far exceed their RMS power rating. The E Series amplifiers have been designed to match this requirement and can deliver huge levels of power for short durations. In order to protect themselves and the loudspeakers that they are driving, continuous signals, such as sine waves, are automatically detected and reduced (ramped down) to a safe level.

  • Page 10: Connections

    Connections INPUTS Note: This amplifier is wired to the latest industry recommendations. PIN1 is connected directly to the chassis/mains earth. If ground loops (mains hum) are encountered remove the screen connection from the other end of the cable and leave it open circuit. If problems persist, consult your dealer/supplier, DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE THE AMPLIFIER.

  • Page 11: Outputs

    OUTPUTS The speaker outputs are via Neutrik Speakon connectors: 2-pole (NL2FC) or 4-pole (NL4FC) connectors can be used. Terminations (all connectors) are as follows:- Pin +1 = +ve signal output Pin -1 = -ve signal output For ease of installing bi-amped or bridged speakers, output connector A also carries output B and output connector C also carries output D.

  • Page 12: Operation

    These are active when the signal is 3dB below the limiting level. Limiter/OCM Indicators (Red LED) The E Series amplifiers incorporate signal limiters, which are preset to prevent clipping with high levels of drive. The red LEDs on the front panel illuminate to indicate operation of the limiters. The output current monitor (OCM) may activate to limit the output current of the amplifier channel - this can occur even if the amplifier has not reached clipping point.

  • Page 13: Fault Indicator

    Normal dynamic signals will not cause the amplifier to overheat unless the ventilation is inadequate. (See installation section and maintenance section.) Fault Indicator (Audio Protection – red LED) If the outputs are shorted or if DC is present, the protection circuit will disengage the outputs and the A/P LED will illuminate.
  • Page 14 The gain should be set to match the signal from the source, e.g. mixer, controller, equaliser etc. AIR FILTER The filter behind the air intake apertures on the front of E SERIES amplifiers should be cleaned or replaced periodically, e.g. 3-6 months. (Filters in amplifiers located in more 'dirty' atmospheres may require more frequent maintenance).
