Rotel Ultimate Guide to the RB-1072 Stereo Power Amplifier

Speaker Wire Connections 5

The RB-1072 has two sets of color coded terminals for each amplifier channel. Having two sets of terminals for each channel makes it easy to biwire the speakers. The speaker terminals accept bare wire, connector lugs, or “banana” type connectors (except in the European Community countries where their use is not permitted).

Route the wires from the RB-1072 to the speakers. Give yourself enough slack so you can move the components to allow access to the speaker connectors.

NOTE: Be sure to to notice the location of the LEFT and RIGHT speaker terminals and connect your LEFT and RIGHT speakers to the correct outputs. Take extra care if using two sets of wires to biwire your speakers.

If you are using banana plugs, connect them to the wires and then plug into the backs of the speaker connectors. When using banana plugs, the collars of the binding post terminals should be screwed in all the way (clockwise).

If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the speaker connectors, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counterclockwise) the binding post collar. Place the connector lug around the shaft, or insert the bundled wire into the hole in the shaft. Turn the collars clockwise 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.

Troubleshooting

Most difficulties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RB-1072, refer to the sugges- tions for the following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RB-1072. Check AC power connections at the amplifier and the AC outlet. Check the front panel power switch. Make sure that it is set to the ON position. If using 12V trigger power-on, make sure that a trigger signal is present at rear panel 12V TRIG IN jack.

No Sound

If the amp is getting AC power, but is producing no sound, check the PROTECTION INDICATOR on the front panel. If lit, see below. If not, check all of your connections and control settings on associated components. Make sure that your input connections and speaker connections match your system configuration.

Protection Indicator Is Lit

The front panel PROTECTION INDICATOR will light when the RB-1072 protection circuits have shut off the amplifier. Typically, this oc- curs only when the amplifier has overheated, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself.
