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.
7. BPM DISPLAY: There are BPM DISPLAYS (34, 35) for the two channels
assigned to each side of the CROSSFADER (27). They update approximately
every 2.5 seconds and digitally display the Beats Per Minute allowing you to
match the beats visually. BPM DISPLAY (34) reflects the Beats Per Minute of the
channel assigned to the left side of the CROSSFADER, and BPM DISPLAY (35)
reflects the Beats Per Minute of the channel assigned to the right side of the
CROSSFADER.
NOTE: A [- -] reading will appear on the BPM DISPLAY if the track
has unclear beats. The [- -] reading will also appear if there is no
signal present.
8. The BEAT OFFSET INDICATORS (36) light when the tracks of the two channels
assigned to the crossfader are within 11 BPMs of each other and display how
aligned the beats of the two channels are. When the RED LEDs light, the beats
are not aligned. When the YELLOW LEDs light, the beats are almost aligned.
When the GREEN LED lights, the beats are aligned perfectly.
NOTE: If the diffence between the two channel’s beats exceed 11
BPM, the BEAT OFFSET INDICATORS will not light.
SUGGESTION: You can use the BPM DISPLAYS to determine which tracks
have similar or the same Beats Per Minute. When mixing two tracks with
similar Beats Per Minute, you can use one source’s pitch control to align the
Beats Per Minute with the other source’s BPM. The BPM DISPLAYS and the
BEAT OFFSET INDICATORS update every 2.5 seconds and will reflect the
change in BPM and indicate when the beats are aligned.
NOTE: Beat mixing is a skill that requires practice. Not every track
has a strong beat, and beat mixing works best with tracks with
clear and strong beats.
9. OUTPUT CONTROL SECTION: The level of the AMP OUT (44, 56) is controlled
by the MASTER (41) slide and the BALANCE CONTROL (40). The BOOTH (42)
control adjusts the level of the BOOTH OUTPUT (45). HINT: The booth OUTPUT
is used by some DJs to run monitor speakers in their DJ booth. You can also use
it as a second ZONE or AMP output. Activating the MONO (39) button (the mono
LED will light) makes the master output mono.
10. 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. The
MIC/TALKOVER (9) switch controls MIC 1 and MIC 2 and has three settings.
When the MIC/TALKOVER (9) switch is in the left position, MIC 1 and MIC 2 and
talkover are off. When the MIC/TALKOVER (9) switch is in the center position
MIC 1 and MIC 2 are on, the MIC INDICATOR (8) will glow, but talkover is off.
When the MIC/TALKOVER (9) switch is in the right position, MIC 1 and MIC 2
and talkover will be on and the volume of all sources except the Mic inputs are
lowered by 16 dB. The TREBLE (4) and BASS (5) controls allow you to fully
adjust the tone of MIC 1 and MIC 2. MIC 1 LEVEL (7) controls the level of MIC 1.
The MIC 2 LEVEL (6) controls the level of MIC 2.
11. CUE SECTION: By connecting a set of headphones to the HEADPHONE (13)
jack, you can monitor any or all of the channels. Press the CUE ASSIGN (20)
buttons for channels 1 - 4 to select the channel or channels to be monitored and
their respective LED indicators will glow. Use the CUE LEVEL (10) control to
adjust the cue volume without effecting the overall mix. By rotating the CUE PGM
PAN (12) control to the left you will be able to monitor the assigned cue signal.
Rotating to the right will monitor the PGM (program) output. Use the CUE SPLIT
(11) button to split the signals from cue and program so that cue will be heard in
one earphone and program will be heard in the other earphone.
12. DISPLAYS: The PEAK HOLD LED METER (37) indicates the MASTER
OUTPUT (44, 56) left and right channel levels. The individual channels each
have their own PREFADER INPUT LEVEL PEAK HOLD LED METERS (38)
which reflect the GAIN (14), HIGH (15), MID (16), and LOW (17) rotary control
adjustments. The CHANNNEL SLIDES (19, 22, 24, 26) will not effect the
PREFADER INPUT LEVEL PEAK HOLD LED METERS (38).
