The 0 position produces flat response. TREBLE Used to increase or decrease the high frequency response.
REMOTE CONTROL TRANSMITTER The remote control transmitter provided with this unit is designed to control all the most commonly used functions of the unit. If the CD player and tape deck connected to this unit are YAMAHA components designed for remote control compatibility, then this remote control transmitter will also control various functions of each component. For Control of This Unit 1 Tuner keys Controls tuner. +: Selects higher preset station number. –: Selects lower preset station number.
Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. English CONNECTIONS CONNECTIONS WITH OTHER COMPONENTS 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 “–”. Also, refer to the owner’s manual for each component to be connected to this unit.
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.
● ● Each antenna should be connected to the designated terminals correctly, referring to the following diagram. Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement.

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. SPEAKERS A B ON ON OFF OFF Adjusting the continuously variable LOUDNESS control This control provides compensation for the human ears’ loss of sensitivity to high and low-frequency ranges at low volume. This control is adjustable to retain full tonal range at any volume level.
Normally, if station signals are strong and there is no interference, quick automatic-search tuning (AUTOMATIC TUNING) is possible. However, if signals of the station you want to select are weak, you must tune to it manually (MANUAL TUNING).
PRESET TUNING MANUAL PRESET TUNING This unit can store station frequencies (selected by tuning operation) by using the PRESET STATIONS buttons. With this function, you can recall any desired station by only pressing the corresponding PRESET STATIONS button. Up to 40 stations (8 stations x 5 groups) can be stored.
English AUTOMATIC PRESET TUNING You can also make use of an automatic preset tuning function for FM stations only. By this function, this unit performs automatic tuning and stores FM stations with strong signals sequentially. Up to 40 stations are stored automatically in the same way as in the manual preset tuning method on page 16.
EXCHANGING PRESET STATIONS You can exchange the places of two preset stations with each other as shown below.
Battery installation English NOTES ABOUT THE REMOTE CONTROL TRANSMITTER Remote control transmitter operation range 2 Remote control sensor 1 3 Within approximately 6 m (19.7 feet) 30° 30° Battery replacement If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes ● Use only AA, R6, UM-3 batteries for replacement. ● Be sure the polarities are correct. (See the illustration inside the battery compartment.
TROUBLESHOOTING If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help. SYMPTOM Amplifier REMEDY Power cord is not plugged in or is not completely inserted. Firmly plug in the power cord. No sound. Incorrect output cord connections.
