REPEATER AMPLIFIERS
Your MIRAGE repeater amplifier has several improvements over our standard model
amplifier.
RACK-MOUNT HEATSINK
The large rack-mount heatsink with horizontal fins keeps the transistor temperature low
longer life in high duty cycle applications. All of the transistors are mounted on 1/4"
plates which have been milled into the aluminum heatsink. This provides
faster transmittal of heat from the devices.
AIR-FLOW CHASSIS
The perforated chassis cover allows heat tha
components to escape outside the amplifier. This, of course, will increase components
PC board life in high duty cycle.
DUAL OVER-TEMP PROTECTION
The amplifier has two temperature protection sensors; one
circuit board. If the amplifier is used under conditions that cause it to overheat, the relay

going into the amp.
REDUCED RELAY WEAR
Repeater operation greatly increases the number of times the relays must change over.
