Press DEMO/ECO.
To re-activate the DEMO mode, press DEMO/ECO until the display window demonstrates the functions of the unit.
To change the brightness of the display
Press DEMO/ECO twice during power on.
The display is dimmer than usual, press DEMO/ECO again to restore normal display.
Using the headphones
Connect the headphones to PHONES jack with a stereo mini plug (ø3.5 mm, 1/8 inch).
No sound is output from the speakers while the headphones are plugged in.

SETTING ECO (POWER ECONOMIZING) MODE
Setting this unit to power economizing mode reduces power consumption.
Press DEMO/ECO repeatedly (during power off) until "ECO MODE" is displayed.
The display disappears and the indicator beside the POWER lights up.
4-Channel Multi-Amplifier System
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 (200Hz - 20 kHz), 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
