About Rotel A family whose passionate interest in music led them to manufac- ture high fidelity components of uncompromising quality founded Rotel over 30 years ago.
Getting Started Thank you for purchasing the Rotel RB-971 Stereo Power Ampli- fier . When used in a high-quality music or home theater system, it provide years of musical enjoyment. The RB-971 is a high-power , two-channel power amplifier , pr ovid- ing the highest level of audio performance.
Polarity and Phasing The polarity — the positive/negative orientation of the connec- tions — for every speaker and amplifier connection must be con- sistent 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.
Bridged Mono Operation [See Figure 3 for bridged operation jumper setting and connec- tion illustration.] The two channels of the RB-971 can be “bridged”.
