uate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage.7English Input Signal Connections 4 See Figure 2 The RMB-1085 has standard unbalanced RCA-type input connectors, the type used on nearly all audio equipment. There is an RCA input for each of the ?ve ampli?er channels. These RCA inputs accept audio signals from preampli?ers or surround sound processors. Use high quality audio interconnect cables for best performance. Speakers The RMB-1085 has ?ve sets of speaker con- nectors, one for each ampli?er channel. Speaker Selection The nominal impedance of the loudspeaker(s) connected to each channel of the RMB-1085 in the various operating modes should be no lower than 4 ohms. Speaker Wire Selection Use insulated two-conductor stranded wire to connect the RMB-1085 to the speakers. The size and quality of the wire can have an au- dible effect on the performance of the system. Standard 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 ap- propriate cables for your system. Polarity and Phasing The polarity – the positive/negative orientation of the connections – for every speaker and ampli?er connection must be consistent so all the speakers will be in phase. If the polarity of one connection is mistakenly reversed, bass output will be very weak and stereo imaging degraded. All wire is marked so you can identify the two conducto...
