BASS, MID AND TREBEL CONTROLS
These controls are used to adjust the tonal bal-
ance of program material to suit individual listen-
ing preference.
TUNING METER
The Model 2252 is equipped with two meters, a
SIGNAL STRENGTH Meter and a TUNING
Meter.
1. The SIGNAL STRENGTH Meter indicates the
signal strength of any AM or FM broadcast.
2. The TUNING Meter operates on FM only and
indicates correct center tuning of the station.
GYRO-TOUCH TUNING CONTROL
AM
Switch the SELECTOR to AM and tune to the
desired station. Then rotate the GYRO-TOUCH
TUNING knob slightly back and forth until the
maximum reading is obtained on the SIGNAL
STRENGTH Meter. The TUNING Meter is not
used for AM.
FM
Switch the SELECTOR to FM and tune to the
desired station. Then slowly rotate the GYRO-
TOUCH TUNING knob back and forth until
maximum reading is obtained on the SIGNAL
STRENGTH· Meter and the TUNING Meter
points to the center scale position. The multiplex
section of the Model 2252 is equipped with elec-
tronically triggered circuits which mute inter-
station noise and automatically switch to the
proper mode of operation for stereo and mono-
phonic FM broadcasts. In addition, the STEREO
indicator light automatically indicates a stereo
broadcast.

FM-25/lS SWITCH
To listen to a Dolbyized FM broadcast, connect a
Dolby noise reduction adaptor between the TAPE
lOUT and IN jacks on the rear panel of the
Model 2252. Depress the FM-25/lS pushswitch,
and depress the TAPE 1 MONITOR switch. With
the FM-25/lS switch in, the audio output signals
an~ preset internally to standard Dolby level, and
the de-emphasis time constant applied to the
signals is also switched to 25/lsec automatically.
SYSTEM l-SPKR-SYSTEM 2 SWITCHES
These switches select the loudspeaker terminals
to which audio power is fed. Either the SYSTEM
1 or the SYSTEM 2 stereo pair of loudspeakers
may be operated individually, or simultaneously
if both switches are depressed. When the two
SYSTEM l-SPKR-SYSTEM 2 switches are in the
normal "out" position, all loudspeaker terminals
are internally disconnected from the power ampli-
fier section. The signal at the headphones jack is
not affected by the SYSTEM l-SPKR-SYSTEM 2
switches. The "out" position allows "private
listening" when stereo headphones are used.
NOTE: Volume level should be reduced to
minimum when switching speakers.
PHONES JACK
This jack accepts headphones utilizing a standard
three conductor phone plug (see Figure 6). It is
internally connected to the power amplifier sec-
tion through isolation resistors to provide ade-
quate sound level with popular low impedance
headphones as well as with high impedance units.
Two or more sets of headphones may be used
with the aid of "Y" connectors. However, output
level will drop as additional headphones are
added. The headphone jack output is not affected
by the SYSTEM l-SPKR-SYSTEM 2 switches.
FM MUTING SWITCH
When tuning to FM broadcasts with the MUTING
switch in its "in" position, the muting circuit will
eliminate interstation noise. To prevent muting
very weak stations along with the noise, the
muting action may be switched off by releasing
the MUTING pushswitch.
LOUDNESS SWITCH
The LOUDNESS switch compensates for human
hearing characteristics by boosting the bass and
treble response at low volume levels to achieve a
more pleasing tonal balance.
