ABOUT YOUR MT110-104 2
MT110-104
16x16 Balanced Stereo Audio
Matrix Switcher Card
The
MT110-104
is a Balanced Stereo Audio Matrix
Switching Card designed for use with the
MultiTasker™ system. When installed in a
MultiTasker™ enclosure, this card allows any input to be independently switched to any of the outputs.
Also, any input may simultaneously drive multiple outputs. All outputs can have only one input source.
All inputs and outputs can be wired for unbalanced or balanced audio, allowing longer cable runs and superior noise resistance.
These cards utilize AC coupling on their inputs for ideal signal transfer characteristics. Switching is controlled with easy-to-use ASCII commands from a control system or computer connected to the RS-
232 port of a MultiTasker™ enclosure. Each card consumes four slots in a MultiTasker™ enclosure and all input and output connections are accomplished via captive screw pluggable terminal blocks.
Although designated as a 16x16 matrix switcher, the
MT110-104
can be used in a variety of ways to provide different capabilities. For example, one
MT110-104
can be used to create two 8x8 stereo audio matrices or a 4x4 and a 2x2 audio matrix.
Each stereo pair must be switched together; you cannot switch the left and right channels of an input independently. The
MT110-104
features individual volume trim control on each input via the RS-232 control.

TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no problems in the supplied
MT110-104.
However, we would like to offer suggestions for the following:
8.1. NO SOUND
A) Cause 1: The source has a problem.
Solution:
Check the source and make sure
that it is working at an
appropriate volume level and all
source connections are correct. If
the source is working and there
is still no sound, see Cause 2.
B) Cause 2: The proper input card may not be selected.
Solution:
Select the card input that is used, by RS-232 accessible
commands in section 7. If no
sound is present, see Cause 3.
C) Cause 3: Cable connections to the destination are incorrect.
Solution:
Make sure that cables are
connected properly. Also, make
sure that the continuity and
wiring are good. If there is still no
sound present, see Cause 4.
D) Cause 4: The destination amplifier has a problem.
Solution 1:
Make sure that the destination
amplifier is powered. If there is
still no sound, see Solution 2
Solution 2
: Set the volume of the destination
amplifier to a reasonable level. If
there is still no sound, call
ALTINEX at (714) 990-2300. or
1-800-ALTINEX.
8.2. DISTORTED SOUND
A) Cause 1: The source level is above 1Vp-p
Solution:
Make sure that the source level is below 1V p-p. If the sound is still
distorted, see Cause 2.
B) Cause 2: The destination amplifier provides excessive amplification.
Solution 1:
Make sure that the source signal
level is high enough so that the
destination amplifier does not
have to provide excessive
amplification and thereby distort
the signal. If there is still sound
distortion, see Solution 2.
Solution 2:
Call ALTINEX at (714) 990-2300
or 1-800-ALTINEX.
8.3. SOUND LEVEL IS LOW
B) Cause 1: The volume levels are inappropriate.
Solution 1:
Turn up the source volume. If sound level is still low, see
Solution 2.
Solution 2:
Turn up the destination amplifier volume. If the sound level is still
low, see Cause 2.
B) Cause 2: Poor signal transmission.
Solution:
Check the cables for continuity
and make sure that connections
are wired properly to verify that
there is good signal transmission.
Note: Test the system by removing the
MT110-
104
card from between the source and the
destination amplifier. If problem persists,
call ALTINEX at (714) 990-2300 or 1-800-
ALTINEX.
