MT113-100/101
3 in Mixer, 1 fixed line level output and
30W amplifier Card
The MT113-100/101 is 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 MT113-100 has a 70 Volt
output for sound reinforcement speakers and the
MT113-101 has 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 MT113-100/101
can accept
balanced or unbalanced audio inputs and the
output can be wired for either balanced or
unbalanced audio output.
The MT113-100 is 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 MT113-101 is primarily designed to utilize
standard 8 Ohms stereo speaker systems. This
card can deliver a full 15 Watts of power to each
speaker.
The MT113-100/101 has 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 MT113-100/101 can
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.
