•
Aud:
To adjust the audio gain, turn Modify wheel 3. Use this to fine-tune the
console's response from a line level audio signal input active in the Audio mode.
•
GM:
To raise or lower the console's Grand Master level, turn Modify wheel 4.
This only controls traits that are assigned to the Grand Master in the fixture's
definition. Typically this is used as a master control for all fixture dimmer traits.
All procedures in this User Guide begin at the MLC 16D Main Screen. You
can return to the MLC 16D Main Screen from any of the Record or Edit
menus by pressing

Installation and Setup
Power Supply
The MLC 16D requires 120 VAC to operate. To turn the console on:
1
Connect the AC power cable (supplied) to a source of AC power.
2
Press the power switch located next to the power input connector.
DMX512 Input and Output
Leviton ships the MLC 16D console with two DMX512 output connectors and one
DMX512 input connector. One output connector is a standard USITT specified
5-pin female XLR. The other is a 3-pin female XLR connector used by some fixture
manufacturers. The input connector is a standard USITT specified 5-pin male XLR.
Be sure the fixture connector pin-out matches that of the MLC 16D. For
example, Martin fixtures use a 3-pin XLR, but reverses pin 2 and 3 from
the norm. Pins 2 and 3 of the 3-pin XLR can be swapped internally to
support these situations. See the chapter "3-Pin XLR Pin Reversal" for
details.
The DMX512 digital signal provides the highest speed, precision, and noise
immunity. When connecting DMX512:
•
Use cable that is specified as RS-485 or RS-422 compatible (shielded, 1 or 2
twisted pair) and use the largest gauge available (22-18 gauge is good for long
runs of 1000 ft).
•
Daisy chain the cable only (no star or home runs) and terminate the end of the
cable with a 120-ohm resistor. (See the fixture's manual for proper terminating
practices).
Using Audio Input
You can use a line level audio signal from an audio source such as a CD player or
mixer to trigger steps in patterns and shows based on the beat of the audio
source. When a line source is present (connected with a standard ¼-in. RCA jack)
and the
Audio
button LED is on, Audio mode is active and will override hold times
programmed in patterns. You can control the audio gain using the Modify wheel 3
and the LCD display. A higher value increases the gain.
