The CROSSFADER CURVE BUTTON (19) allows you to adjust the kind
of curve the crossfader has. Depress the crossfader curve button
to make the curve steep and cutting (perfect for scratching).
Release the crossfader curve button to make the curve gradual
and gentle. The CROSSFADER REVERSE SWITCH (29) allows you to
reverse the crossfader so that CHANNEL 2 is controlled by the left
side of the crossfader and CHANNEL 1 is controlled by the right side
of the crossfader.
NOTE: When the CROSSFADER REVERSE SWITCH
(29) is activated (moved to the right), only the crossfader
reverses. The Channel Slides, Gain and tonal controls do
not reverse.
5. PUNCH IN: The PUNCH IN BUTTONS (18, 44) allow you to add a
channel’s signal to the mix when the crossfader is set to the opposite
channel.
6. BPM DISPLAY: There are BPM DISPLAYS (25, 37) for Channel 1 and
Channel 2. They update approximately every 2.5 seconds and digitally
display the Beats Per Minute allowing you to match the beats visually.
BPM DISPLAY (25) reflects the Beats Per Minute of Channel 1, and
BPM DISPLAY (37) reflects the Beats Per Minute of Channel 2.
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.
7. The BEAT OFFSET INDICATORS (30) light when the tracks of Channel
2 and Channel 3 are within 11 BPMs of each other and display how
aligned the beats for Channel 1 and Channel 2 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.
8. OUTPUT CONTROL SECTION: The level of the MASTER OUTPUT (3) is
controlled by the MASTER (43) control.
NOTE: The RECORD OUT (5) has no level control. The
level is set by the channel slides and the gain controls of
the selected channel. The tonal qualities are set by the
low, mid and high controls of that same channel.
9. 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 (14) switch has three settings. When
the MIC/TALKOVER (14) switch is in the left position, the mic and
talkover are both off. When the MIC/TALKOVER (14) switch is in the
center position the mic is on, the MIC INDICATOR (15) will glow, but
talkover is off. When the MIC/TALKOVER (14) switch is in the right
position, the mic and talkover will be on and the volume of all sources
except the Mic input are lowered by 16 dB. MIC LEVEL (17) controls
the level of the MIC. The MIC EQ (16) control allows you to fully adjust
the tone of the MIC.
10. CUE SECTION: By connecting a set of headphones to the HEADPHONE
(38) jack, you can monitor either channel or both together. Move the
CUE SWITCH (40) to the left to monitor CHANNEL 1. Move the CUE
SWITCH (40) to the right to monitor CHANNEL 2. By rotating the CUE
PGM PAN (41) 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 LEVEL (42) control to adjust the
headphone volume without effecting the overall mix.
11. DISPLAY: The peak hold, dual function DISPLAY (27) indicates either
the MASTER output left and right levels or the channel 1 and channel
2 levels. You can choose the option you want by pressing the
DISPLAY (28) button.
NOTE: When the DISPLAY (27) is in the channel 1/channel 2
display mode, by adjusting the individual channel gain
controls, you can increase or decrease the signal to match
the other channels signal. The channel slides and
crossfader have no effect on the display readings.
