See the tuner's instruction manual for more information. See your MD recorder's, CDR's, or cassette deck's instruction manual for more information. Synchro Recording When using a CDR, MD recorder, or cassette deck to record from a CD player, you can start the recording process simply by starting playback on the CD player. · Simply connecting an cable will not enable the system functions. You must make an analog audio connection between the A-933 and each component as well. · See the instruction manual supplied with each component for more information about the system functions. · When using the A-933 as a power amplifier (MAIN IN function), the system functions are unavailable. 10 Connecting the A-933--Continued 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 connections 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. Left (white) L Right (red) R · Push each plug in all the way to make a good connection (loose connections can cause noise or malfunctions). Right! Wrong! Connecting Your Speakers 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 connect 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 negative (­) 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. · Don't connect more than one wire to each speaker terminal. · Don't connect a speaker to more than one pair of speaker terminals.

[. . . ] When only SPEAKERS B is selected (B indicator on), speakers connected to the SPEAKERS B terminals, and a connected subwoofer will output sound. · To use a turntable with a moving-coil (MC) type cartridge, you need a commercially available MC phono preamp (page 15). Noise can be heard. · Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so don't bundle them together. · An audio cable may be picking up interference. Try repositioning your cables. The tone controls don't work. · If the TONE/DIRECT indicator is green, Direct mode is selected and the tone controls have no effect. [. . . ]
