the use to the presence of un-insulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock.

CAUTION

IMPORTANT SAFETY INSTRUCTIONS

The exclamation point within the equilateral triangle is intended to alert the user to the
presence of important operation and maintenance (servicing) instructions in the literature
accompanying this appliance.

CAUTION

To prevent electric shock, do not use this polarized plug with an extension cord, receptacle or other

PART NAMES AND FUNCTIONS

1. Source input selector switch - These
switches are used to select the input
source assigned to each channel. Each
channel may only be assigned one input
source at a time.

2. Input gain - These knobs are used to
adjust the audio source signal input gain
for a channel. Never use the gain control
to adjust a channels output volume.
Setting the gain level properly will ensure
a clean output signal.

3. Channel EQ control - These knobs are
used to adjust the high, mid and low
range levels of a channel allowing for a
maximum midrange gain of 10dB or
maximum decrease of -35dB. Turning
the knob in a counterclockwise direction
will decrease the amount of high/mid/low
range applied to a channel signal, turning
the knob in a clockwise direction will
increase the amount of high/mid/low
applied to a channel signal.

4. Mic Ievel - Adjusts microphone level.

5. Mic treble/bass EQ - These knobs are
used to adjust the treble (or bass) levels
of the microphone with a maximum
signal gain of 12dB or maximum signal
decrease of -12dB. Turning the knob in a
counterclockwise direction will decrease
the amount of treble (or bass) applied to
the microphone signal, turning the knob
in a clockwise direction will increase the
amount of treble (or bass) applied to
microphone signal.

6. Channel fader - Adjusts the volume for
CH1 and CH2.

7. Mic ON/OFF/Talkover switch - To set
mic on and off, when switch at the
talkover position, the mic on, the sound
level for everything other than mic will
decrease to around 14dB.

8. PFL/Master switch - The position of
this switch will determine the level meter
mode. In the “Master” position, the meter
will detail the out level of the left and right
channels. In the “PFL” position, the left
side of the meter will indicate monaural
level of the PGM.

9. Crossfader - Used to mix the signals
from the 2 channels.

10. FX ON button - This button functions
as an effect Master on/off button and is
used to activate and deactivate the
effects.

11. Cue mixing - Used to preview
channel audio to your headphones.
Listen here before bringing up channel
faders or moving the crossfader.

12. Cue level - This knob is used to
adjust the headphone output level.

13. Master knob - Adjust the level of the
master output.

14. Level meter - The dual LED's
indicators are used to detail either the
master output level, a combination of the
master output level or the PGM monaural
level.

15. Effect select knobs - Used to select
the type of effect mix desired, 3 functions
(Echo, Zip and Roll) can be choosed.

16. Effects cue - Used to select the beat
effects to be monitored with headphones.

17. Effects mode switch - Used to select
the desired crossover effect mode.

• Fader : In this mode you can use the
crossfader to control the crossover
effects and perform start/stop (recue)
functions.

• Off : Crossover effects are disabled.

• Auto : In this mode you don’t have to
use the crossfader : simply push one of
the buttons and the mix will be done
automatically in full beat sync!

18. TAP/BPM button - Tap this button to
switch TAP/BPM function.

19. Effect beat selector buttons - To
select different beat (also change the
time parameter) accoding to the
measured BPM of the effector.

20. Depth feedback (parameter Y) - Used
to adjust the value of the parameter Y
(mix ratio or resonance or feedback) of
the effector.

21. Time array (parameter X) - Used to
adjust the value of the parameter X (time)
of the effector.

22. Effects selector - Used to select
desired effects.

23. Input selector - Used to select the
source to be effected.

24. Effects indicator - When any of the
effects are in use, these indicators will
grow to match any of the effects that may
be functioning.

25. Depth feedback display - The depth
feedback digital display will indicate the
parameter ratio percentage.

26. Time array display - This display will
signify the pitch percentage speed. Any
adjustments will be based on this default
setting.

27. BPM display - This meter will display
the source BPMs to be effected.

Front Panel

28.

Mic input jack - This jack will accept a

standard 1/4” male plug.

29. Fader start switch - When the unit
has been connected with a control cable
to a CD player, this is th e ON/OFF switch
for the function to automatically start
playing and stop (back cue) of the CD
player using the channel fader or
crossfader.

30. Crossfader curve switch - Used to
select the rising curve patterns for the
crossfader function.

31. Channel fader curve control - Adjusts
the curve of the channel faders between
quick, normal, or long fade.

32. Channel fader curve mode switch ­Used to select the channel fader curve
desired.

33. Headphones jack - Used to connect
your headphones to the mixer.

Rear Panel

34. Power switch - Turn this unit power
ON/OFF.

35. AC inlet - Use the accessory power
cord to connect to an AC power outlet.

36. Master balanced output - These 1/4”
TRS jacks provide a balanced line level
output.

37. Master outputs - Left & Right line
level unbalanced RCA.

38. Rec out - The record out level is
dictated by the channel and cross fader
level, it is not influenced by the master
volume control.

39. Send out jack - Connects to the input
of an outboard signal processor.

40. Return input jack - Connects to the
output of the outboard signal processor
to create an effect loop.

41. Line input jacks - These jacks are
inputs for any line level device.

42. Ph/Aux input jacks - These jacks are
inputs for a phono (RIAA) stage for
magnetic (MM) cartridge or a line level
device.

43. Aux/Phono selector switches - These
switches are used to change the mode of
phono input jacks. When connecting
turntable to these jacks be sure the
switch is in the phono position, and when
using line level input devices select AUX.
Always be sure main power is shut off
before change the position of the
Aux/Phone selector switch.

44. GND terminals - Connect each of
your turntable ground leads to either of
the two ground terminals.

45. USB socket - Use the accessory USB
cord to connect to a PC.

46. Fader start control jacks - Connect

QUICK SETUP DIAGRAM

Study this setup diagram. Make sure all faders are at "zero" and all devices are off. First,
connect all input sources and processors. Next, connect your microphone and monitor
headphones. Finally, connect the stereo outputs to the power amplifier(s) and/or audio
receivers such as tape decks. Plug your mixer into AC power. Now you are ready to switch
everything on.

IMPORTANT: Always switch on your audio input sources such as turntables or CD players first,
then your mixer, and finally any amplifiers. When turning off, always reverse this operation by
turning off amplifiers, then your mixer, and then input devices.
