compatible dual CD player connected to channels one and two. When the Fader "q" Start option is turned on, sliding the crossfader to the far left position will trigger playback on CD player 1. When the crossfader is pushed to the far right position, playback on CD player 2 will begin, and CD player 1 will return to the cue position. Refer to your American Audio CD player user manual for setting CUE POINTS. Turn the ON/OFF SWITCh to the OFF position to disengaged “q” Start function and resume to a normal fader. 21. 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 channels one and channels two will be even. 22. Lcd screen - For in ForM ation see pa Ge 17. 23. cross Fader curve adJust Ment - This rotary knob is used to change the way the cross- fader will operate. The crossfader can operate in different modes, “NORMAL CURVE”, “ qUIC k CURVE” or any variation of the two. ( quick Curve usually used for scratching). 24. spLit cue - This button will activate the "Split Cue" function. When used with a set of stereo headphones, the Split Cue function will assign the Cue signal to the left channel of the headphones and the Program (main output) signal to the right channel of the headphones. Essentially splitting the cue signal in half. This process will allow for headphones mixing. The Cue mixing Control (20) will also work in conjunction with function. Please note that this function will only work with a set of stereo headphones. 25. 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 (26) is set to minimum before you put the headphones on. 26. cue LeveL voLuMe controL - This knob is used to adjusts the headphone volume output level. Turn the knob in a clockwise direction to increase the headphone \ volume. 27. cue MiXinG controL - This functions allows you to monitor the Cue level as well as the Program (main output) level in your headphones. A channels Cue Level may only be monitored if the channels Cue (12) function is selected. To select a channels cue function press the Cue button (12) that is directly associated with the specific channel you wish to monitor. You may use the mixing function to blend both the Cue level and the Program level together. You can vary the output level to either hear more or less of either of the two levels. Turning the Cue Mixing knob to the CUE position (left) will allow you to hear more of the Cue level. Turning the knob to the PgM position (right) will allow you to hear more of the Program level (main output). You may also use the Cue Mixing Control to hear either the Cue level or the Program level exclusively. If the knob is in the full CUE position you will only hear the cue level, if the knob is in the full PgM position you will only hear the main output. This function is especially useful when mixing without an monitor. 28. taLkover controL - This function decreases all signal output except the microphone signal. The amount of decrease is preset to -14d b and is not user selectable. 29. Mic 2 voLuMe controL - This fader controls the output volume of miCroPhone 2 (2). however, master volume is controlled by the MASTER VOLUME CONTROL (14).\ 30. Mic 1 voLuMe controL - This fader controls the output volume of miCroPhone 1 (1). ©American Audio® - www.americanaudio.us - MX-1400 DSP Instruction Manual Page 11 MX-1400 DSP CONTROLS aND FUNCT iONS cont.
however, master volume is controlled by the master volume Control (14).
31. channeL voLuMe Fader - These faders are used to control the output signal of any source
assigned to its particular channel. however, master volume is controlled by the master volume
Control (14).
32. Fader assiGn sWitch - This switch assigns a channel to the Crossfader (21). When a
channel is assigned to the left side of the Crossfader (21) that channels output level is routed to
and controlled by the Crossfader (21). Sliding the Crossfader (21) to left position will send the
volume output of the assigned channel to the master volume level (14), siding the Crossfader
(21) to right position will cut that channels volume to master volume level (14). The reverse is
true for the right channel fader assign switch. When the assign switch is set to the "OFF" position the
crossfader will have no function.
33. Mic 1 on/o FF button - This switches MIC 1 On and Off.
Mic 2 on/o FF button - This switches MIC 2 On and Off.
34. MiCROPhONE 2 TREbLE CONTROL - This knob is used to adjust the treble levels of the
Microphone with a maximum signal gain of 12db or maximum signal decrease of -12db. Turning the
knob in a counter-clockwise direction will decrease the amount of treble applied to the microphone
signal, turning the knob in a clockwise direction will increase the amount of treble applied to micro-
phone signal.
MiCROP hONE 2 MiDRaNGE CONTROL - This knob is used to adjust the midrange levels of a
channel allowing for a maximum midrange gain of 12db or maximum decrease of -12db. Turning the
knob in a counter-clockwise direction will decrease the amount of midrange applied to a channel
signal, turning the knob in a clockwise direction will increase the amount of midrange applied to a
channel signal.
MiCROPhONE 2 baSS CONTROL - This knob is used to adjust the low frequency levels of the
microphone with a maximum signal gain of 12db or maximum signal decrease of -12db. Turning the
knob in a counter-clockwise direction will decrease the amount of bass applied to the microphone
signal, turning the knob in a clockwise direction will increase the amount of bass applied to micro-
phone signal.
35. MiCROPhONE 1 TREbLE CONTROL - This knob is used to adjust the treble levels of the
Microphone with a maximum signal gain of 12db or maximum signal decrease of -12db. Turning the
knob in a counter-clockwise direction will decrease the amount of treble applied to the microphone
signal, turning the knob in a clockwise direction will increase the amount of treble applied to micro-
phone signal.

36. channeL Gain controL - This adjustment is 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. An improper gain level adjustment will send a distorted
signal throughout the entire audio line which may damage speakers and amplifiers. To properly set a
channels gain level control:
1. be sure the master volume Control (14) is set to level 8.
2. Set the Channel fader (31) to level 8.
3. begin playback on an audio source connected to the channel you are adjusting.
4. Use the gain Control to adjust an average output volume of +4 db.
5. Repeat this step for all channels.
