    Never stack other hi-fi components on top of the amplifier. Due to the layout of Rega’s amplifier circuit designs, they are virtually insusceptible to Electro Magnetic interference, and by virtue of the extruded aluminium case, emit practically no Electro Magnetic radiation.

  • Page 7: Amplifier And Speaker Protection

    01/04/03 12:32 Page 7 Amplifier and Speaker Protection The power LED will flash if the following has occurred. 1) Thermal cutout has been activated. If the amplifier reaches a temperature liable to cause internal electronic damage a thermal protection sensor will activate, and protect the speaker, and alert the user of the fault condition.

  • Page 8: Short Circuit Protection

    If in the event that the speaker leads are shorted, the short circuit protection will protect the output stage from excessive currents. This innovative Rega protection circuit is not placed in the audio signal path and therefore does not affect sound quality.

  • Page 9: Power Amplifier Inputs

    12:32 Page 9 Power Amplifier Inputs The Exon 3 can be used in conjunction with any pre-amplifier with a standard line output level (approximately 1V). The red (Input) socket on the back of the amplifier is for input from the pre-amplifier.

  • Page 10: Input Connections

    Page 10 Input Connections All connections are made using RCA (phono) type connectors. The sockets on all Rega amplifiers are clearly marked red and white. Input: the lower row marked in RED. Link: the upper row marked in WHITE. Important: Always turn off the amplifier when changing leads, especially speaker cables.

    This prevents audible clicks being heard through your speakers as you switch on your equipment. A start-up delay has been designed on Rega amplifiers to prevent any damage being done to your speakers when your system is initially switched on.
