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. 5 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. If removed, no sound will be output from this unit. q If you will use this unit with an external unit connected between the PRE OUT and MAIN IN terminals, make sure that the CD DIRECT AMP switch and the PURE DIRECT switch on the front panel are turned off. q If you will use this unit as a power amplifier, connect the outputs of an external control amplifier etc. In that case, this unit's controls will not function except the PHONES jack and the SPEAKERS switches, so use the controls on the external control amplifier to make volume adjustment etc. q 6 OPERATIONS AX-590 2 7 1, 6 4 7 3 7 1, 6 4 7 4 l2 l0 8 6 4 3 2 AX-490 2 3 Select the speakers to be used.

By doing so, the audio signals bypass the BASS, TREBLE, BALANCE and LOUDNESS controls, thus eliminating any alterations to the audio signals. AX-590 only * The SUBSONIC FILTER switch and the PRE OUT/MAIN IN terminals are also bypassed. Using the CD DIRECT AMP switch You can enjoy the purest possible CD sound from your CD player by setting this switch so that the indicator illuminates. By doing so, CD's input signals are sent to the built-in amplifier special for CD directly bypassing the INPUT selector, BASS, TREBLE, BALANCE and LOUDNESS controls, and then sent to the power amplifier. This signal routing reproduces the purest CD sound eliminating any alterations to the CD signals. AX-590 only * The SUBSONIC FILTER switch and the PRE OUT/MAIN IN terminals are also bypassed. PURE DIRECT CD DIRECT AMP Setting the SUBSONIC FILTER switch AX-590 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 Note If both the CD DIRECT and PURE DIRECT switches are on, only the CD DIRECT switch will function. OFF When you listen with headphones Connect the headphones to the PHONES jack. [. . . ] The distance or range within which the remote control transmitter can be used decreases. The PHONO (MM/MC) switch on the rear of this unit is set to the improper position. The CD DIRECT AMP or PURE DIRECT switch is ON. Direct sunlight or lighting (of an inverter type of flourescent lamp etc. ) is striking the remote control sensor of the main unit. The batteries of this remote control transmitter are too weak. Replace the batteries with new ones. 13 SPECIFICATIONS Minimum RMS Output Power per Channel Maximum Input Signal (1 kHz, 0. 007% THD) Channel Separation (Vol. [. . . ]
