as a source. The connection that has the most bass output is the correct connection. The incorrect
connection will have very little sound output as each of the two speakers will attempt to cancel the sound the
other is making due to the opposite polarity, and motion, of the drivers.
If you connect your speakers to the RA 971 with bare wire, strip approximately 1 1/2 mm (~1/2") of the
insulation from the end of the wire and connect to the terminal of the amplifier by turning it around the center
post of the speaker terminal. The RED or BLACK terminal knob should be turned counterclockwise to extend
the terminal for connecting. When you have wrapped the wire around the post, tighten the terminal by turning
the red or black knob clockwise to grasp the wire FIRMLY. Ensure that NO LOOSE WIRE is outside the
terminal housing. Repeat this operation for all of the terminals. If you use banana plugs or 4 mm plugs they
may be connected to the end of the speaker terminals by inserting them into the holes provided.

HUM AND NOISE IN A STEREO SYSTEM
In any high fidelity stereo installation it is possible for noise to be created by the physical location of some of
the components.
If your system has hum or excessive noise it is possible to diagnose this before trying to
have repairs made to a properly functioning component. If the system only hums with one of the source
components, it should be unplugged from the system. Turn the volume down or turn the power off before you
unplug the suspected component. If the system still hums after the suspected component has been removed,
you may require service. First though, you should disconnect all of the other components except the speakers.
If there is no hum after this then a source component in the system is either in need of physical relocation, has
a bad RCA patch cable or needs repair. Connect the components one by one until the problem reappears. If
you are unable to locate the source of the problem, consult your ROTEL

A FINAL WORD FROM ROTEL
We have designed this amplifier for high performance using test equipment and the human ear. We believe
that both methods are useful in the design of audio electronics.
This is time consuming but we feel that the
music benefits from this care and attention to detail.
We realize that there are many choices available and we
thank you again for choosing RA 971 to amplify your music.
Enjoy the music!
