other cleaning detergents,
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DONOTUSE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
CONNECTION.
OPERATION:
5. MIC JACK:
1/4" microphone input jack (5).
6. VOLUME:
Overall volume is controlled by the VOLUME (6) control.
10.BASS:
The BASS (10) control adjusts the relative level of the low
frequencies in the sound.
11. PHONE JACK: 1/4" headphone input jack (11).
12.MONO:
When the MONO (12) button is activated (LED is fit), the two
stereo channels are blended together to produce monophonic sound.
This blend minimizes rumble and surface noise in old monophonic
records. Push the button a second time (LED goes out) to get back to
stereo mode.
13.MUTE:
Pushing this button reduces the volume of the amplifier output
signal by approximately 20 dB. Pressing the button a second time
removes the muting. The MUTE (13) has no effect on the microphone
volume.
14.LOW CUT:
The output from a turntable usually contains strong but
inaudible impulses at infrasonic frequencies (below 20Hz) due to disc
warps, stylus/tonearm resonance, and vibrations that reach the
turntable. If these are amplified at full strength, they may waste
amplifier power and muddy the sound. The LOW CUT FILTER (14)
attenuates these unwanted signals.
15.LOUDNESS:
When pressed, the LOUDNESS (15) button engages a
"loudness compensation" circuit which, at low-to-medium volume,
boosts the bass and treble response.
USING THE GROUND LIFT SWITCH:
Depending on your system configuration, sometimes applying the
ground will create a quieter signal path. Sometimes lifting the ground
can eliminate ground loops and hum to create a quieter signal path.
1. With the unit on, listen to the system in idle mode (no signal present)
with the ground applied (the GROUND LIFT SWITCH (25) in the left
position).
2. Then turn the power off before moving the GROUND LIFT SWITCH
(25). Lift the ground by moving the GROUND LIFT SWITCH to the right,
turn the power back on and listen to determine which position will
provide a signat devoid of background noise and hum. Keep the
GROUND LIFT SWITCH in the ground position if the noise level remains
the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE UNIT IN ANY WAY. TERMINATION
OF THE AC GROUND CAN BE HAZARDOUS.
