When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”.
English CONNECTING SPEAKERS Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass.

Adjust the balance of the output volume to the left and right speakers to compensate for sound imbalance caused from speaker location or listening room conditions. Selecting the SPEAKER system Because one or two speaker systems can be connected to this unit, the SPEAKERS switches allow you to select speaker system A or B, or both at once.
Using the PURE DIRECT switch PHONO (MM/MC) switch You can enjoy the purest possible sound from your audio sources by setting this switch so that the indicator lights up. By doing so, the audio signals bypass the BASS, TREBLE, BALANCE, LOUDNESS controls, SUBSONIC FILTER switch, MODE switch and the PRE OUT/MAIN IN terminals, thus eliminating any alterations to the audio signals. Select either MM or MC position depending on your PHONO cartridge, Moving Magnet or Moving Coil type.
