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.
