Quick start:

American Audio

®

would like to thank you for your purchase of this great audio product.

For those of you that are too impatient to read the entire user manual we have compiled these quick start instructions. We hope that you will at least read through these instructions to familiarize yourself with the basics of this mixer. The MX-1400 DSP is part of American Audio’s continuing evolution in audio technology. This unit has been built and designed to meet the needs of a typical DJ. We have attempted to provide you with the most reliable product on the market by using only components constructed of the finest material.

Master LeveL -

Use this level to control your main volume output. Try never to send an output of more than +4db to your system. Signal at levels higher than this will start to distort and may cause damage to your system and speakers. Remember that a distorted signal from you mixer will only be multiplied throughout your system.

channeL Gain LeveL -

The channel gain levels are not to be used as volume controls. Never use the channel trim to set the output volume. These controls are used to aid in distortion control. Use these control to preset your signal level before the crossfader. With your channel faders in the maximum position, use the channel trim level to set an average output level of about +4db on you master level meter.

headphones -

To avoid damaging your headphones always be sure the headphone volume level

(26) is set to minimum before plugging them in. To avoid sever hearing damage, never put the headphone on without making sure the headphone level is turned down.

Main Mic -

The main mic connector uses a combo plug that allows you to connect either a 1/4” unbalanced jack or by a standard 3-pin XLR balanced connector. The main mic also has an independent volume control. When feedback occurs when using the mic, try lowering the level this may reduce the feedback. Always leave the mic level to it’s minimum level when not in use.

note: We recommend that you use a 500-600ohm microphone for the best sound quality.

phono/auX Line LeveL seLector sWitch -

This switch is used to change the selected input from phono to line and vice versa. The switch selectors are on the rear panel.

(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.

MX-1400 DSP CLEaNiNG

Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue build up.

1. Use normal glass cleaner and a soft cloth to wipe down the outside casing.

2. Use a cleaner specially designed for electronics to spray in and around the knobs and switch.

This will reduce small particle built up that can effect the proper operation of the mixer.

3. Cleaning should be carried out every 30-60 days to prevent heavy built up.

4. Always be sure to dry all parts completely before plugging the mixer in.

Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, dust, dew).

MX-1400 DSP CROSS FaDER REPLaCEMENT

The crossfader is “hot Swapable” which means it may be replaced at any time, even when power is applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any other model fader may seriously damage your mixer.

Replacing the Crossfader:

1. Disconnect the mixers main power supply

2. Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws that hold the crossfader in place.

3. gently remove the crossfader from its seated position. You may need to wiggle the crossfader slightly to remove it.

4. After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the

PC board. grasp the crossfader by its base and pull the ribbon cable by its connector not the actual cables. The connector is designed to only fit one way, so don’t worry about the connec tors orientation.

5. Connect the new crossfader to the ribbon cable and replace in reverse order.
