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. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers. q q q One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the SPEAKERS A or B terminals. Use speakers with the specified impedance shown on the rear of this unit. Banana Plug connections are also possible (except for Scandinavian models). Simply insert the Banana Plug connector into the corresponding terminal. How to Connect: Red: positive (+) Black: negative (­) Unscrew the knob. 5mm (1/4") insulation from the speaker wires. ] Tighten the knob and secure the wire. ABOUT THE ACCESSORY TERMINALS AC OUTLETS (SWITCHED) AX-470> Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this unit's POWER switch or the provided remote control transmitter's POWER key. These outlets will supply power to any component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts. <Except Australia, U. K. and Europe models of PRE OUT/MAIN IN terminals <For AX-570 only> REMOTE CONTROL (PHONO) connector If you have a YAMAHA turntable with a terminal for remote control, connect it to this connector by using the cable provided with the turntable. q VOLUME, BASS, TREBLE, BALANCE, LOUDNESS controls and PURE DIRECT switch settings have no effect on the material being recorded. 7 Adjusting the BALANCE control 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. <AX-570> BALANCE l 2 3 4 L5 5R 0 l 2 3 4 <AX-470> SPEAKERS SPEAKERS Adjusting the BASS and TREBLE controls BASS l 2 3 4 5 5 0 l 2 3 4 2 3 4 5 5 4 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. TREBLE l 0 l 2 3 1 LOUDNESS l 2 FLAT 30 dB l0 9 BASS : Turn this clockwise to increase (or counterclockwise to decrease) the low frequency response. 3 4 5 6 7 Set to the "FLAT" position. 8 TREBLE : Turn this clockwise to increase (or counterclockwise to decrease) the high frequency response. 2 Set to the loudest listening level that you would listen to. 3 LOUDNESS l 2 3 4 5 6 7 FLAT 30 dB l0 9 8 Turn so that the desired volume can be achieved. 8 ENGLISH Using the PURE DIRECT switch You can enjoy the purest possible sound from your audio sources by setting this switch so that the indicator illuminates. By doing so, the audio signal bypasses the BASS, TREBLE, BALANCE and LOUDNESS controls, eliminating any alterations to the audio signal. * Concerning AX-570 only, the SUBSONIC FILTER switch and the PRE OUT/MAIN IN terminals are also bypassed. Setting the PHONO switch <For AX-570 only> Select either MM or MC position depending on your PHONO cartridge, Moving Magnet or Moving Coil type. However, if you use a high output MC cartridge, select MM position. PHONO MC PURE DIRECT MM Setting the SUBSONIC FILTER switch <For AX-570 only> If you set this switch to "ON" position, undesirable ultra-lowfrequency signals caused by turntable rumble or warped records can be cut out without losing sound quality. SUBSONIC FILTER ON OFF When you listen with headphones Connect the headphones to the PHONES jack. When listening with headphones privately, set both the SPEAKERS A and B switches to the OFF position. PHONES 9 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, tuner, turntable, equalizer, and tape deck connected to this unit are YAMAHA components, then this remote control transmitter will also control various functions of each component.
