Meter Switch
The meter switch selects which signals are
monitored by the two LED meters. In the
input position, the left meter displays the
line input signal and the right meter is not
active. In the output position, the left meter
displays the left line output and the right
meter displays the right line output.
Stereo Intensity Control
The stereo intensity control determines the
amount of stereo simulation that is pro-
duced. The stereo intensity control is active
only when the internal system status switch
is set to the front panel position. In the fully
counterclockwise position, no simulated
stereo is produced. The mono input signal
is sent equally to the left and right outputs.
As the control is turned clockwise, the
amount of stereo simulation increases. The
size of the stereo image that is produced is
directly related to the setting of the stereo
intensity control.
Stereo Intensity Trim Control
To the lower left of the stereo intensity
control is a small opening in the front panel.
This opening allows access to a trim poten-
tiometer. This trim pot controls the stereo
intensity when the internal system status
switch is set to the fixed — music or fixed —
music & voice positions. This trim pot allows
the sound of the Generation II to be ad-
justed, but “hides” the control from unautho-
rized personnel.
Panel Controls Disabled LED
On the left side of the front panel is a yellow
panel controls disabled LED. This LED is lit
when the internal system status switch is
set to the fixed — music or fixed — music &
voice positions. It alerts the user that the
front panel mode switch and stereo intensity
potentiometer functions are not active. This
also indicates that the stereo intensity trim
potentiometer is active.
Mode LEDs
The operating mode of the Generation II is
displayed by two red LEDs labeled music
and music & voice. If the panel controls
disabled LED is lit, the fixed operating mode
will be displayed via one of the two LEDs. If
the front panel controls are active, the LEDs
will follow the operation of the mode switch.
Audio Signal Level LEDs
Two sections of the LED meter display the
audio input and output levels. These meters
are not intended to be calibrated, VU- or
peak-type, but strictly to provide a relative
level indication. The green LEDs show the
presence of low level signal in the Genera-
tion II. The yellow LEDs show the presence
of moderate signal levels. The red LEDs
light when the signal level approaches,
within about 10dB, the internal clipping
level.
Normal Operation
You should now feel confident that the
Generation II Stereo Simulator has been
carefully installed and is ready to go to
work. With normal audio input signals, the
green and yellow LEDs should light most of
the time. On peaks, the red LEDs may light.
However, if they light steadily, you should
reduce the level of the input signal. If you
have any questions concerning the unit,
now is a good time to give us at Studio
Technologies a call. Otherwise, set the
controls for your desired simulated stereo
sound and that’s it.
