Q-221™ Controls and Features Cont.
6. CHANNEL FADER - These faders are used to control the output signal of any source assigned to
its particular channel.
7. FADER CURVE SWITCH - This switch is used to change the way the crossfader will operate. The
crossfader can operate in two different modes, NORMAL CURVE and QUICK CURVE (Quick Curve is
usually used for crabbing).
8. Q-START ON/OFF SWITCH - This function works in conjunction with a compatible American DJ “Q”
Start CD player. When used with a compatible CD player, you can use the crossfader to start and stop
the CD play. The ON/OFF “Q” START (8) switch activates the fader “Q” start feature. When the fader
“Q” start feature is activated sliding the CROSSFADER (14) from left to right will play or cue any CD
player connected to the controller jacks (16) on the rear of the unit.
For example, connect a compatible dual CD player connect to mixer channels one and two (refer
to your CD player manual for proper set-up). Be sure the Fader “Q” Start feature is activated on
both channels. Slide the crossfader to the channel one position (full left) and begin playback on
CD drive one. Slide the crossfader to the channel position (far right). This will immediately
trigger the play function on CD drive two and return CD drive one to cue mode. To return to
normal fader operation turn the Fader “Q” Start ON/OFF SWITCH (8) to the OFF position.
9. MAIN POWER SWITCH - This is the main power ON/OFF button. A yellow LED above the power
switch will glow to indicating power is ON. Before main power is applied, be sure you have made all con-
nections to the mixer. Also be sure your amplifi er(s) is tuned off. Remember to avoid damaging pops,
mixer on fi rst and turned off last.
10. MASTER VOLUME CONTROL - This rotary knob is used to control the master output level
(volume). To avoid distorted output try to maintain an average output signal level +4 dB. Be sure this
volume control is always set to zero before turning the unit on.
11. CUE MIXING CONTROLLER - This knob selects the channel for monitoring. The monitor signal
comes from the Prefader. This means it will not be affected by the channel faders. You can monitor
each channel individually. Connect your headphones to the HEADPHONES jack. Turn the CUE MIXING
CONTROL knob to channel you wish to monitor. If the CUE MIXING CONTROL (11) is set to the center
position, you can monitor both the channels at once.
12. CUE LEVEL VOLUME CONTROL - This knob adjusts the headphone volume output level. Turning
the knob in clockwise direction will increase headphone volume output.
13. HEADPHONE JACK - This jack is used to connect your headphones to the mixer allowing you to
monitor the cue source. Use headphones only rated at 8 ohms to 32 ohms. Most DJ headphones are
rated at 16 ohm, these are highly recommended. Always be sure the CUE LEVEL VOLUME (12) is set
to minimum before you put the headphones on.
14. FEATHER FADER PLUS CROSSFADER - This fader is used to blend the output signals of chan-
nels one and two together. When the fader is in the full left position (channel 1), the output signal of
channel one will be controlled by the master volume level. The same fundamentals will apply for chan-
nel two. Sliding the fader from one position to another will vary the output signals of channels one and
two respectively. When the crossfader is set in the center position, the output signals of both the chan-
nels one and channels two will be even.
