USING HEADPHONES
To listen in privacy or monitor the audio source inputs so you can locate
an exact passage or selection before mixing it, insert a pair of stereo
headphones (not supplied) with a 1/8-inch plug into the headphones jack
on the lower right front corner of the mixer. Your local Radio Shack
store sells a wide selection of headphones.
Listening Safety
Do not listen at extremely high volume levels. Extended, high-volume
listening can lead to permanent hearing loss. Follow these guidelines to
protect your hearing, especially when you use headphones.
Always start by setting the volume to the lowest level possible before
you begin listening.
Put the headphones on, then gradually increase the volume as necessary.
Once you set the volume, do not increase it. Over a period of time,
your ears adapt to the volume level, so a volume level that does not
cause discomfort might still damage your hearing.
Caution: As you begin to mix, be careful not to get into the habit of
always increasing volume levels to achieve the proper balance.
You can bring high levels down just as easily as you can bring
low levels up. Try to keep the independent level controls in
the middle position (3 to 8), and adjust the overall volume
with the MASTER volume control as well as the volume control
of your input audio equipment. Listening at excessive volume
levels will soon give you "Tired ears" and you won't be as
pleased with your finished product later.
MONITORING THE INPUTS
You can listen to the audio input sources before mixing them so you can
monitor them and decide when to mix in a desired input at the proper time.
1. Set POWER OFF/ON to ON to turn on the mixer's power. The VU meter's
indicator lights.
2. Turn on the audio input source you want to mix, and set it to play
(or continuously talk into the microphone).
3. Set the MONITOR OUT/IN switch that corresponds to the audio input
source you turned on in Step 2 to IN.
Note: Do not slide up the MASTER volume control before you are ready
to put the sound "on the air."
4. Slowly slide up MONITOR until you hear the signal through the
headphones at the desired volume level.
5. Set MONITOR OUT/IN to OUT.
6. Repeat Steps 2-5 to select and adjust the volume level of the other
audio input sources, one at a time.
MIXING THE INPUTS
You can select up to six of the eight available audio input sources for
mixing.
1. Set the selected audio input sources to play.
2. Set the corresponding MIC 1, MIC 2, MIC 3/PHONO, MIC 4/CD 1, 2, and
CD 3, volume controls to approximately 8-10.
3. Set the following controls as desired.
Control Setting Audio Source
MIC 3/PHONO MIC 3 To mix the microphone
connected to the MIC 3 input jack.
PHONO To mix the turntable connected to
the PHONO input jack.
MIC 4/CD 1 MIC 4 To mix the microphone connected to
the MIC 4 input jack.
CD 1 To mix the CD player connected to
the CD 1 input jack.
4. Slide up the MASTER volume control until you get an average reading
of 0 on both output level VU meters.
Notes: Once you set the MASTER volume control, do not move it away from
its initial setting. To get the desired output volume, see Steps
7 and 8.
The output level VU meter indicates the total output signal levels
(both the left and right channels) of all input sources being
mixed.
5. Set the MASTER OUTPUT level selector:
To 0.775V for high sensitivity input, such as in an area with low
background noise.
To 1.5V for low sensitivity input, such as in an area with high
background noise.
6. Set EQUALIZER ON/BYPASS as desired (See "Using the 5-Band Frequency
Equalizer").
7. When adding an audio input source, adjust the corresponding MIC 1,
MIC 2, MIC 3/PHONO, MIC 4/CD 1, CD 2, and CD 3, volume controls
so you get an average reading of 0 on both output level VU meters.
8. Adjust the receiver amplifier's (not the mixer's) volume control to
the desired volume.
9. To turn off the mixer, set POWER ON/OFF to OFF. The VU meter's light
turns off.
USING THE DJ'S MICROPHONE
One of the four microphone inputs (MIC1) is designed for the operator's
(or DJ's) microphone. To improve the sound of the DJ's voice, adjust BASS
and TREBLE as desired.
USING THE 5-BAND FREQUENCY EQUALIZER
You can tailor the sound processed through the mixer to match your
acoustic surroundings and suit your personal preference. With the five
sliding frequency controls, you can vary the level of a narrow band of
frequencies centered around the noted frequency (60 Hz, 250 Hz, 1 kHz,
4 kHz, 16 kHz).
Set EQUALIZER ON/BYPASS to ON to turn on the frequency equalizer. Then
slide the control up to boost the indicated frequency range or down to
reduce it. Each level can be increased up to a maximum of + 12 dB and
decreased down to a minimum of - 12 dB.
Note: If you set the control to the center position, the frequency range
is unaltered.
60 Hz Adjust the frequencies in the low bass range (low organ notes
and bass drums). Reduce rumble or other low frequency noise.
250 Hz Adjusts the frequencies in the low to middle bass range (low
organ notes, bass drums, timpani and some low-bass).
1 kHz Adjust the range of frequencies in the middle frequency range
where the ear is most sensitive (vocals).
4 kHz Adjust the range of frequencies in the lower high frequency
range (flutes, oboes, violins, piccolos, and other treble
instruments). Boosting this range adds vibrancy to the upper
voices. Too much can make the music sound harsh.
16 kHz Adjusts high-frequency sounds (cymbals, flutes, and violins).
To turn off the frequency equalizer and disable the frequency controls,
set EQUALIZER BYPASS/ON to BYPASS.
