Rotel RX-1050 owner manual Protection Circuit, Specifications

RX-1050AM/FM Stereo Receiver

IR OUT Jacks

See Figure 6.

The IR OUT 1 & 2 jacks send IR signals re- ceived at the ZONE REM IN jack or the EX- TERNAL REM IN jack to an infrared emitter placed in front of a source component or to Rotel CD players, cassette decks, or tuners with a compatible rear panel IR connector.

This output is used to allow IR signals from Zone 2 to be sent to the source components, or to pass along IR signals from a remote in the main room when the sensors on the source compo- nents are blocked by installation in a cabinet. See your authorized Rotel dealer for information on IR repeater systems.

NOTE: The EXT REM IN jack located to the right of these jacks is for use with an external IR sensor duplicating the front-panel IR sen- sor and located in the primary zone. It should not be used for ZONE 2 IR connections.

Protection Circuit

A thermal protection circuit protects the am- plifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RX-1050’s protection cir- cuit is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the am- plifier if temperatures exceed safe limits.

Should a faulty condition arise, the amplifier will stop playing. If this happens, turn the amplifier off, let it cool down for several min- utes, and attempt to identify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset.
