QM-MD5x1, Slot 1 Analog Input Signal Descriptions (continued)
INPUT DESCRIPTION
QMLink5Preset# [This signal is operative only if Auto
Compensation is NOT enabled.]
Sets the preset number that will be recalled when
RecallQMLink5Preset is held high.
The peaking and boost values are applied to IN
5.
Valid analog values range from 1d to 254d. Out-
of-range values are ignored. If no preset
numbers are specified, IN 5 will recall preset 1
when the MD5x1 is rebooted.
VideoInpSelect Select the video source to be switched to the QM
output. Valid analog values range from 0 (for no
source) through 5. Out-of-range values are
ignored.
Thus to route a video source from RGB 4 to the
QM output, initialize VideoInpSelect to 4d.
AudioInpSelect Selects the audio source to be switched to the
program audio portion of the QM output. Valid
analog values range from 0 (for no source)
through 5. Out-of-range values are ignored.
Thus to route an audio source from AUD 4 to the
QM output, initialize AudioInpSelect to 4d.
RemoteMicSelectA Selects the remote microphone pair that will be
mixed with the two local microphones and
switched to the MIC 1 channel of OUT and the
mixing section of AUDIO OUT. This remote
microphone pair is referred to as MIC A-1 and
MIC A-2.
Valid analog values range from 0d to 1d. Out-of-
range values are ignored.
• 0d = No remote microphone source
• 1d = Remote microphone pair of IN 5
Peaking_5 Applies peaking at IN 5.
Peaking improves the transmission of the
encoded audio signal over cable lengths up to
300 feet.
Valid peaking values range from 0% to 100%,
adjustable in 1% increments. Peaking is also
programmable using DMT Software.
The following table lists recommended
peak/boost values for various cable lengths.
