8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied
MT109-100; however, we would like to offer suggestions for the following:
8.1 LED is Not Lit
Cause 1:
The card is not plugged in.
Solution: Plug the card in all the way. If the LED turns on, the problem
is solved. If the LED is still not on, see Cause 2.
Cause 2:
The card is not plugged in all the way.
Solution: Push the card in all the way. If the LED is still not on, see
Cause 3.
Cause 3:
The card cage slot has a problem.
Solution 1: Test the card in other slots of the card cage. If the slot was
damaged, the card may work in other slots. If other slots work
and the LED turns on, the problem is the card cage slot. The
card cage may require service. Please, call ALTINEX at
(714) 990-2300. If the other slots do not work and the LED is
still not lit, see Solution 2.
Solution 2: Take any other known good card with an LED and verify that
the slot used is good by seeing if the other card’s LED lights in
that slot. If it lights, then the original card may be the source
of the problem. Please, call ALTINEX at (714) 990-2300.
8.2 No Sound
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.
Cause 2:
The proper card input 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.
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.
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.
8.3 Sound Distortion
Cause 1:
The source level is above 1 Vp-p.
Solution: Make sure that the source level is below 1 Vp-p. If the sound
is still distorted, see Cause 2.
Cause 2:
The destination amplifier provides excessive amplification.
Solution: 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, call ALTINEX at (714) 990-2300.
8.4 Sound Level is Low
Cause 1:
Input volume is low.
Solution 1: Turn up the source volume. If the 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.
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 MT109-100 card from between
the source and the destination amplifier. If the problem persists,
call ALTINEX at (714) 990-2300.
