MT113-102/103 - 3 in Mixer, 1 fixed line level output and 10W amplifier Card
The
MT113-102/101
Amplifier Card designed for use with the MultiTasker™. When installed in the Basic Enclosure (MT100-100), This card allows connection of up to three line level balanced/ unbalanced microphone inputs. The Card has a built in dual 5W power amplif ier. The Volt output for Sound reinforcement speakers and

7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts: function, card ID, and unit ID. [Function, Car d ID, Unit ID]
Example:
[VERC3U2] VER = Function C3 = Card ID
U2 = Unit ID For detailed information regarding function, see each command description.
Card ID is an assigned value from 1 to 19, which represents the number of slots. Card ID 0 (C0) is used for the controller (see user’s guide for the MT100-100). Changing the position of a card will significantly affect the commands recorded on software definitions or a thir d par t y contr ol system .
Unit ID has a value from 0 to 9. Unit ID 0 should be used for single unit operation. If the Unit ID is set t o 0, then each command can be used without Ui (use command [SETU0]; see user’s guide for the MT100-
100).
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit I D ot her than zero
[VERC3]: equivalent to
