Speaker Selection
If only one set of speakers will be used at any given time, the speakers may have an imped- ance as low as 4 ohms. If there are times when both the A and B speakers will be used, all the speakers should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loud- speakers will present any problems for the

Polarity and Phasing
The polarity – the positive/negative orienta- tion of the connections – for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the po- larity of one connection is reversed, bass output will be very weak and stereo imaging de- graded. All wire is marked so you can iden- tify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with dif- ferent color conductors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and negative conductors and be consistent with every speaker and amplifier connection.
Speaker Connection
Turn off all the components in the system be- fore connecting the speakers. The

If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counter- clockwise) the binding post thumbscrews. Place the connector lug or wire around the bind- ing post shaft. Turn the thumbscrews clock- wise to clamp the connector lug or wire firmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connectors.
IR Inputs and Outputs

This 3.5 mm
NOTE: The IR signals from the EXTERNAL REMOTE IN jack can be relayed to source components using external IR emitters or hardwired connections from the IR OUT jacks.
IR Output ![12 Volt Trigger Outlet](/images/new-backgrounds/17411/1741115xi10.webp)
The IR OUT 1 and 2 jacks send IR signals re- ceived at the EXTERNAL 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 to pass along IR signals from a remote control when the sensors on the source components are blocked by installation in a cabinet.
See your authorized Rotel dealer for informa- tion on IR repeater systems.
NOTE: The EXT REM IN jack located next to the these jacks is for use with an external IR sensor duplicating the front panel IR sen- sor and located in the primary zone.
