System 1230 Stereo  (130-1250)    Basic Operation      Faxback Doc. # 16393
Rack System

You can use your system's amplifier and frequency equalizer with all of the
system 1230's audio sources.

Follow these steps to operate your system.

1.  Turn VOLUME to MIN.

2.  Press POWER to turn on the system.  The indicator on the VOLUME knob
    lights.

    NOTE:  The system waits about 3 seconds before it turns on the
           speakers.  This protect the speakers from signal spikes as the
           system warms up.

3.  Press one of the source selection buttons to choose the audio source.

    NOTE:  If you press BAND SELECT or a memory station button, the system
           automatically selects TUNER.

4.  Start the audio source.

5.  Adjust VOLUME for a comfortable listening level.

6.  Adjust BALANCE and frequency equalizer controls as desired.

Surround-Sound

You can add rear speakers to enjoy a surround-sound effect from any program
source.  To use surround-sound, press in SURROUND.  (See "Connecting
Additional Speakers", Faxback Doc. # 16392).

Frequency Equalizer

Adjust the five slide controls on the frequency equalizer for the desired
sound.  You can adjust the tone in five frequency ranges.  Slide the
control up to boost the indicated frequency range, or down to reduce the
frequency range.  If you set the control to the center position, the
frequency range is unaltered.

  50 Hz - Use this control to boost or cut the frequencies in the low bass
          range.  Low organ notes and bass drums fall within this range. 
          You can also use this control to compensate for poor bass
          response in recordings or to reduce rumble or other low-frequency
          noise.

 250 Hz - Use this control to adjust frequencies in the middle-bass range.
          Timpani and some low-brass instruments fall within this range.

  1 KHz - Use this control to adjust the range of frequencies where the ear
          is most sensitive.  Vocals are within this range.

4.5 KHz - Use this control to adjust the range of frequencies that includes
          vocals and upper-midrange instruments.  The clarinet and
          saxophone fall within this range.

 15 KHz -  Use this control to adjust high-frequency sounds.  Cymbals,
           flutes and violins fall within this range.

Power Level Master

The power level meter shows you stereo output power level.  As the volume
increases, more power level indicator light.

Headphone Listening

For private listening or to monitor while you record, you can connect low-
impedance headphone (not supplied) with a 1/4 inch plug.  To connect the
headphones, insert the headphone cord's plug into the PHONES jack. 
Connecting headphones mutes the external speakers.

Hearing Comfort and Your Health

Do not listen at extremely high volume levels, especially when using
headphones.  Extended, high-volume listening can lead to permanent hearing
loss.

To protect your hearing, follow these guidelines when you use headphones.

    Set the volume to the lowest setting before you begin listening.  After
    you begin listening, adjust the volume to a comfortable level.

    Once you set the volume, do not increase it.  Over time, your ears
    adapt to the volume level, so a volume level that does not cause
    discomfort might still damage your hearing.
