MT113-102/103 - 3 in Mixer, 1 fixed line level output and 10W amplifier Card

The MT113-102/101is a Stereo Audio Power 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 amplifier. The MT113-102has 70 Volt output for Sound reinforcement speakers and MT113-103has Stereo Output to drive 8 Ohms speakers direct.

Mixing of input is selected via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker™ Basic Enclosure. The MT113-102/103can accept balanced or unbalanced audio inputs and the output can be wired for either balanced or unbalanced audio output.

The MT113-102is primarily designed to utilize the 70 Volt speaker system. It has on board Transformer to convert low impedance signal to high voltage, high impedance output signal. This card can supply total of 10 Watts of power to the speakers.

The MT113-103is primarily designed to utilize the standard 8 Ohms stereo speaker systems. This card can deliver full 5 Watts of power to each speaker.

Through RS-232 control, the MT113-102/103can be controlled to adjust signal level of each input in 32 steps. In addition the volume, treble and bass of the output amplifier can be adjusted in 32 steps.

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

Phantom Power +12V can be connected to the microphone input using dip-switch located on the PCB.
