Connecting the A-933 —Continued
Speaker Connection Precautions
You can connect one or two sets of speakers (A/B) to
the A-933, and select which set outputs sound, or use
both sets at the same time.
• Connecting one set of speakers (A or B): Only con-
nect speakers with an impedance of 4 ohms or more
but less than 16 ohms. If you use speakers with a
lower impedance, and use the A-933 at high volume
levels for a long period of time, the built-in protection
circuit may be activated.
• Connecting two sets of speakers (A and B): Only
connect speakers with an impedance of 8 ohms or
more but less than 16 ohms. If you use speakers with
a lower impedance, and use the A-933 at high volume
levels for a long period of time, the built-in protection
circuit may be activated.
• Disconnect the power cord from the wall outlet
before making any connections.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals to only positive
(+) terminals, and negative (–) terminals to only nega-
tive (–) terminals. If you get them the wrong way
around, the sound will be out of phase and will sound
unnatural.
• Unnecessarily long and very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the
positive and negative wires.
Doing so may damage the
A-933.
• Don’t connect more than one
wire to each speaker terminal.
Doing so may damage the
A-933.
• Don’t connect a speaker to more than one pair of
speaker terminals.
Before Making any Connections
• Always refer to the instructions that came with the
component that you are connecting.
• Do not plug in the power cord until all connec-
tions have been properly made.
• Do not bind audio cables with power cords and
speaker cables. Doing so may adversely affect the
sound quality.
• To prevent interference, keep power cords and
speaker cables away from the tuner’s antenna.
RCA Audio Connection Color Coding
• Red connectors are used for the right channel, and
white connectors are used for the left channel.
• Push each plug in all the way to make a good con-
nection (loose connections can cause noise or mal-
functions).
