tangle in BLUE above the pushbutton. The BLUE light
indicates that the main speakers are off and no pro-
gram can be heard from them.
To hear program from both main and remote
speakers, both the MAIN and REMOTE pushbuttons
must be out and the BLUE lights must be off.
FRONT PANEL JACKS
TAPE INPUT - TAPE OUTPUT
When a tape recorder is plugged into the front
panel jacks all the facilities for TAPE 2 are automatic-
ally switched to the front panel jacks. A tape recorder
plugged into the TAPE 2 INPUTS and OUTPUTS on
the back panel is automatically disconnected.
Use the front panel pushbutton TAPE 2 to record
or playback from a tape recorder plugged into the
front panel jacks.
HEADPHONES
The front panel HEADPHONE jack has been de-
signed to feed low impedance dynamic headphones.
Electrostatic headphones generally require higher
power than dynamic headphones. They must be con-
nected to the output connectors on the power am-
plifier.
Plug headphones into the front panel HEADPHONE
jack. Adjust the front panel VOLUME control for com-
fortable headphone listening. (See Pg. 8}
An amplifier in the C 28 provides the power that
feeds both the HEADPHONE jack on the front panel
and the LINE OUTPUT jacks on the rear panel. If you
choose to listen to headphones only it is not neces-
sary to operate the power amplifiers that feed the
loudspeakers.
To turn the power amplifiers off use the switch on
the top panel of the C 28 marked POWER AMPLIFIER.
This switch controls the AC to the green POWER
AMP receptacles on the back panel. With this switch
in the OFF position nothing will be heard from the
speakers.
Balancing your Stereo
The performance and enjoyment of a stereo sys-
tem is greatly increased when the sound is properly
balanced. The balance of the stereo system is af-
fected by many things including room acoustics,
furniture placement, room shape, small differences
in loudspeakers, etc. Factors that affect proper stereo
balance are correct phase for both channels and
equal program loudness.
TO BALANCE LOUDNESS
1. Set the MODE to MONO.
2. Play a familiar recording.
3. Turn the BALANCE control to the 12 o'clock posi-
tion.
4. While the program is playing, stand between the
two loudspeakers. Listen for a difference in loud-
ness between speakers. Balance the system by
adjusting the controls on the power amplifiers.
Next, set the MODE selector to STEREO. If there
is then a difference in loudness turn the BAL-
ANCE control toward the speaker that is not as
loud. Adjust the BALANCE control until the sound
is equally loud from both speakers.
