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 loudspeakers will present any problems for the RA 03 See your authorized Rotel dealer if you have any questions Speaker Wire Selection Use insulated two conductor stranded wire to connect the RA 03 to the speakers The size and quality of the wire can have an audible effect on the performance of the system Stan dard speaker wire will work but can result in lower output or diminished bass response particularly over longer distances In general heavier wire will improve the sound For best performance you may want to consider special high quality speaker cables Your authorized Rotel dealer can help in the selection of cables for your system Polarity and Phasing The polarity the positive negative orientation of the connections for every speaker and amplifier connection must be consistent so all the speakers will be in phase If the polarity of one connection is reversed bass output will be very weak and stereo imaging degraded All wire is marked so you can identify the two conductors There may be ribs or a stripe on the insulation of one conductor The wire may have clear insulation with different color condu

5. A 03 has both thermal and over current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions The protection circuits are independent of the audio signal and have no impact on sonic performance Instead the protection circuits monitor the temperature of the output devices and shut down the amplifier if temperatures exceed safe limits Most likely you will never see this protection circuitry in action However should a faulty condition arise the amplifier will stop playing and the LED indicator on the front panel will light up If this happens turn the amplifier off Let it cool down for several minutes and attempt to identify and correct the problem that caused the protection circuitry to engage When you turn the amplifier back on the protection circuit will automatically reset and the indicator LED should go out In most cases the protection circuitry activates because of a fault condition such as shorted speaker wires or inadequate ventilation lead ing to an overheating condition In very rare cases highly reactive or extremely low imped ance speaker loads could cause the protection circuit to engage If the protection circuitry triggers repeatedly and you are unable to isolate and correct the faulty condition contact your authorized Rotel dealer for assistance in troubleshooting English Troubleshooting Most difficulties in audio systems are the
