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, 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.
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 AlWA's built-in subwoofer system
incorporates a subwoofer capable of powerful, satisfying bass
performance with true stereo separation.

To search for a station quickly (Auto Search)
Keep the + or > button pressed until the tuner starts
searching for a station. After tuning in a station, the search stops.
To stop the Auto Search manually, press the < or W button.
The Auto Search may not stop at stations with very weak signals.
When an FM stereo broadcast contains noise
Press MONO TUNER on the remote control repeatedly while
pressing SHIFT so that "MONO" lights up on the display.
Noise is reduced, although rece~tion is monaural.
To restore stereo recep;ion, p;ess this button until "MONO"
disappears.
To change the AM tuning interval
The default setting of the AM tuning interval is 10 kHz/step. If
you use this unit in an area where the frequency allocation system
is 9 kHz/step, change the tuning interval.
Press POWER while pressing +>.
To reset the interval, repeat this procedure.

When the AM tuning interval is changed, all preset stations are
cleared. The preset stations have to be set again.
