Cautions
1. All operating instructions should be read before using this equipment.
2. To reduce the risk of electrical shock, do not open the unit. There are
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
3. Do not expose this unit to direct sunlight or to a heat source such as a
radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.
5. When moving this equipment, it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DO NOT USE SPRAY CLEANERS OR LUBRICANTS ON CONTROLS
OR SWITCHES.
Connections
1. Make sure that the POWER (22) switch is in the off position.
2. This unit comes supplied with a 15 volt AC adaptor. Plug the male pin
of the adaptor into the rear panel POWER JACK (6). Then plug the
adaptor into a proper power source.
3. To connect the mixer to your amplifier, use the MASTER (1) jacks on
the rear panel.
4. The unit is equipped with one microphone input. The MIC JACK (15)
is a 1/4" (6.35 mm) and is located on the front panel.
5. On the rear panel are 2 stereo PHONO/LINE (3, 4) inputs, 1 stereo
PHONO (5) input and 1 stereo LINE (2) input. The PHONO/LINE
SWITCHES (8, 9) enable you to set the (3, 4) inputs to Phono or Line.
The PHONO (5) input will accept turntable inputs only. A GROUND (7)
screw for you to ground your turntables is located on the rear panel.
The stereo LINE (2) input will accept any line level input such as a CD
player or a cassette player.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (26) jack.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER (22) switch. The power will turn on and
the POWER LED (21) will glow RED.
2. CHANNEL 1: The GAIN (12) control allows you to individually adjust
the gain of Channel 1. Switch (13) allows you to select PHONO 1 (5)
or the LINE 1/PHONO 2 (4) inputs. CHANNEL SLIDE (14) controls the
input level of this channel.
3. CHANNEL 2: The GAIN (23) control allows you to individually adjust
the gain of Channel 2. Switch (24) allows you to select the LINE 2/
PHONO 3 (3) or the LINE 3 (2) input. The CHANNEL SLIDE (25)
controls the input level of this channel.
4. CROSSFADER SECTION: The CROSSFADER (20) allows the mixing of
one source into another. The left side of the CROSSFADER is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER in
your unit is removable and, should the need arise, can be easily
replaced. Crossfader units are available in two varieties: part RF-45
(which is identical to the crossfader supplied with this mixer) has a
45 mm travel from side-to-side, while the PSF-45 is equipped with a
special “curve” designed for scratch mixing.
To install a new crossfader:
1. Unscrew the outside FADER plate screws (B). Do not
touch the INSIDE SCREWS (C).
2. Carefully lift the fader and unplug the CABLE (D).
3. Plug the new fader into the cable and place it back in the
mixer.
4. Screw the fader to the mixer.
5. TALKOVER SECTION: The purpose of the talkover section is to allow
the program playing to be muted so that the mic can be heard above
the music. When the TALKOVER (11) button is pushed, the
TALKOVER INDICATOR (10) will glow and the volume of all sources
except MIC are reduced by -16 dB. MIC (17) controls the level of the
talkover MIC.
6. CUE SECTION: By connecting a set of headphones (26), you can
monitor either Channel 1 or Channel 2. Select Channel 1 by moving
the CUE SWITCH (19) to the left. Move to the right for Channel 2.
Use the CUE (18) control to adjust the headphone volume without
affecting the overall mix.
7. DISPLAY: The DISPLAY (16) indicates the MASTER output left and
right levels as controlled by the MASTER LEVEL (27).
