MT113-100/101

3 in Mixer, 1 fixed line level output and

30W amplifier Card

The MT113-100/101is a Stereo Audio Power Amplifier Card designed for use with the MultiTasker. This card allows the connection of up to two line level balanced/unbalanced inputs and one microphone. The card has a built-in, dual 15W, power amplifier. The MT113-100has a 70 Volt output for sound reinforcement speakers and the MT113-101has stereo output to drive 8 Ohms speakers direct.

Mixing of inputs is selected via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker enclosure. The MT113-100/101can accept balanced or unbalanced audio inputs and the output can be wired for either balanced or unbalanced audio output.

The MT113-100is primarily designed to drive a 70 Volt speaker system. It has an on-board transformer to convert a low impedance signal to a high voltage, high impedance output signal. This card can supply total of 30 Watts of power to the speakers.

The MT113-101is primarily designed to utilize standard 8 Ohms stereo speaker systems. This card can deliver a full 15 Watts of power to each speaker.

The MT113-100/101has a separate power supply that is used to the drive output of the power audio amplifier. This power supply has universal power input and can operate from 90 to 240 volts AC.

Through RS-232 control, the MT113-100/101can be controlled to adjust the signal level on each input in 16 steps. The output volume, treble and bass of the amplifier can be adjusted in 16 steps.

All three inputs to the amplifier are mixing inputs and can be adjusted from 0db to –60db.
