CAUTION  
Do not connect this unit or other components to the main power until all connections between components are  
complete.  
All connections must be correct: L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. If the connections are faulty,  
no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be  
unnatural and lack bass. Refer to the owner’s manual for each of your components.

CONNECTIONS  
CAUTION  
The IMPEDANCE SELECTOR switch must be set to the appropriate position before connecting speaker sets. See  
page 4 for details.  
Do not let the bare speaker wires touch each other or any metal part of this unit. This could damage this unit and/or the  
speakers.  
Do not connect this unit or other components to the main power until all connections between components are  
complete.  
Bi-wire connection  
1
Remove approximately 10 mm (3/8 in) of  
insulation from the end of each speaker  
cable and twist the exposed wires of the  
cable together to prevent short circuits.  
Bi-wire connection separates the woofer from the  
combined midrange and tweeter section. A bi-wire  
compatible speaker has four binding post terminals. These  
two sets of terminals allow the speaker to be split into two  
independent sections. With these connections, the mid and  
high frequency drivers are connected to one set of  
terminals and the low frequency driver to another set of  
terminals.

Connect the other speaker to the other set of terminals in  
the same way.  
CAUTION  
When making bi-wire connections, set the IMPEDANCE  
SELECTOR switch to HIGH or LOW depending on the  
impedance of your speakers:  
6 Ω or higher: HIGH  
4 Ω or higher: LOW  
Connecting via banana plug  
(Except for Asia, U.K. and Europe  
models)  
See page 4 for more information about the IMPEDANCE

frequency response.  
The center position produces a flat response.  
Notes  
• For the A-S500, audio signals are not output via the LINE 2  
REC or LINE 3 REC output jacks when LINE 2 or LINE 3 is  
selected with the REC OUT selector.  
• For the A-S300, audio signals are not output via the LINE 2  
REC or LINE 3 REC output jacks when LINE 2 or LINE 3 is  
selected with the INPUT selector.  
• This unit must be turned on in order to record.  
• The VOLUME, BASS, TREBLE, BALANCE and  
LOUDNESS controls and the PURE DIRECT switch have no  
effect on the source being recorded.  
• Check the copyright laws in your country before recording from  
records, CDs, radio, etc. Recording copyright-protected  
material may infringe on copyright laws.  
BASS  
When you feel there is not enough bass (low frequency  
sound), rotate clockwise to boost. When you feel there is  
too much bass, rotate counterclockwise to suppress.  
Control range: –10 dB to +10 dB (20 Hz)  
TREBLE  
When you feel there is not enough treble (high frequency  
sound), rotate clockwise to boost. When you feel there is  
too much treble, rotate counterclockwise to suppress.  
Control range: –10 dB to +10 dB (20 kHz)  
Adjusting the BALANCE control  
The BALANCE control adjusts the sound output balance  
of the left and right speakers to compensate for sound  
imbalance caused by speaker locations or listening room  
conditions.  
Adjusting the LOUDNESS control  
Retain a full tonal range at any volume level, thus  
compensating for the human ears’ loss of sensitivity to  
high and low-frequency ranges at low volume.  
REC OUT  
(A-S500 only)  
CAUTION  
1
Rotate the REC OUT selector on the front  
panel to select the source you want to record  
(A-S500 only).  
If the PURE DIRECT switch is turned on with the  
LOUDNESS control set at a certain level, the input signals  
bypass the LOUDNESS control, resulting in a sudden  
increase in the sound output level. To prevent your ears or  
the speakers from being damaged, be sure to press PURE  
DIRECT switch AFTER lowering the sound output level  
or AFTER checking that the LOUDNESS control is  
properly set.

Do not drop the remote control.  
Do not leave or store the remote control in the  
following types of conditions:  
– high humidity, such as near a bath  
– high temperature, such as near a heater or a stove  
– extremely low temperatures  
Do not use old batteries together with new ones.  
Do not use different types of batteries (such as alkaline  
and manganese batteries) together. Read the packaging  
carefully as these different types of batteries may have
