SETTING POWER ECONOMIZING MODE
When you set power economizing mode to "ECO ON" or "ECO
AUTO", the unit reduces power consumption by conducting four
ECO operations as follows.
¢ The unit (all the illumination of the display and the buttons)
blacks out when the power is turned off. Only the red indicator
lights up.
¢ If DIMMER (1-3) is selected, the illumination of the display and
the buttons brighten for 10 seconds only when you press a
button, or turn VOLUME or MULTI JOG.
¢The display dimmer mode is set to dimmest, the button
illumination lights off, and the volume is set to minimum (0)
when the unit turns on by timer recording.
ein addition to the three operations of ECO ON, the unit
automatically turn itself off if you do not operate it and the sound
source is mute for 10 minutes (only when "ECO AUTO?" is
selected).
7 Press ECO.
"ECO MODE' will be displayed.
2 Press ENTER within 4 seconds.
The current power-economizing mode status will be displayed.
If the power-economizing mode is off: ECO OFF.
If the power economizing mode is on: ECO ON or ECO AUTO.
3 Turn MULTI JOG within 4 seconds to select the 2
power-economizing mode.
Example: When "ON" is selected.
4 Press ENTER within 4 seconds to set the mode.
If the clock is not set, the unit does not black out.
Instead, the DEMO will begin when the power is turned off.

4-Channel Multi-Amplifier System
es SS
To provide reinforcement for the ultra-low frequencies, in addition
to the Left/Right 2-channel amplifier used to reproduce mid-to-
high-range frequencies, this system incorporates a second L/R
2-channel amplifier just for reproduction of ultra-low frequencies
— making it, in effect, a 4-amplifier system. By utilizing discrete
amplifiers for mid-to-high-frequencies and low frequencies, high-
quality sonic reproduction that is virtually free from distortion
can be realized.
This Multi Amplifier System, which utilizes independent circuitry
for the different frequency ranges, enables superb sonic
reproduction free from distortion.

Built-in Subwoofer System
The built-in subwoofer System has a separate subwoofer cavity
area that is part of the loudspeaker cabinet structure, which acts
as a sonic filter to cut distortion components. (In the Multi Amplifier
System, the ultra-low frequency signals transmitted from their
own independent amplifier are reproduced in this area.) This
separate construction gives a clear, rich definition to bass
reproduction and it can realize clear, well-defined mid-to-high
frequency signals.
And AIWA's built-in subwoofer system incorporates a subwoofer
capable of powerful, satisfying bass performance with true stereo
separation.
