Connect the SPEAKERS terminals to your speakers with cable of the proper gauge, cut as short as possible. If the speakers are improperly connected, no sound will be heard. Connect each speaker making sure that the polarity (+ and –) is correct. ● ● One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either SPEAKERS A or B terminals. Use speakers with the specified impedance shown on the rear panel.
GND terminal (for turntable use) PRE OUT/MAIN IN terminals Connecting the ground wire of the turntable to this terminal will normally minimize hum, but in some cases better results may be obtained with the ground wire disconnected. Removing the jumper pins enables this unit to independently perform the functions of a control amplifier and a power amplifier. These terminals are for connection of a signalprocessing system such as a graphic equalizer or sound processor.
VOLTAGE SELECTOR switch (General model only) Make sure that the power to the unit is off, before you set the switch. Select the appropriate setting for your speaker system. If the pre-set setting is incorrect, set the switch to the proper voltage for your area. Upper position English IMPEDANCE SELECTOR switch Consult your dealer if you are unsure of the correct setting. WARNING 4 Ω: If you use either speaker system A or B, the impedance of each speaker must be 4 Ω, or higher.

Setting the SUBSONIC FILTER switch AX-592 and AX-892 only You can enjoy the purest possible sound from your sources by setting this switch so that the indicator illuminates. The signals bypass the BASS, TREBLE, BALANCE and LOUDNESS controls, the SUBSONIC FILTER switch (AX-592 and AX-892 only), and the PRE OUT/MAIN IN terminals (AX-592 and AX892 only), eliminating any alterations to the signals.
