programmable output. The tabs along the bottom of the notebook are used to select one of the
programmable outputs for setup.
To set up one of the programmable outputs, select a function type from the Function list. Once
selected, controls appear which are used to choose the specific feature or features of the DM84
that the function applies to. These choices will vary according to the nature of the program-
mable output function values. The following function types are available:
• Monitor Input Ch Activity (CA) This function monitors audio input channels and activates
the programmable output if the audio input has become "active", meaning that it has become
the dominant signal source on a designated audio output channel. Naturally the audio
input must be routed to the designated audio output via a mix matrix crosspoint assignment
for the function to work properly. This is useful if some action must be taken in response to
activity on specific audio input channels, such as in "video follows audio" applications. The
time response of this function can be adjusted by means of the Channel activity controls
described below. This function is configured by selecting:
• One or more audio inputs to be monitored
• Exactly one audio output, or the special selection ANY
The selection of a single specific audio output channel was introduced in DM84 firmware
version 1.2.0 and allows better control of "video follows audio" applications since only a single
audio input may be "active" at any time on a given output channel (NOM bus). Selecting audio
output ANY results in the same behavior found in earlier versions of the DM84 firmware where
the programmable output would become active if one of the monitored audio input channels
became the dominant signal source on any of the audio outputs.
• Monitor Prog Input State (IS) This function monitors a programmable input. The response
varies according to the function type selected for the programmable input:
• Analog Input RP Gain Control - Active when the gain is in the upper half of range.
• Inc Input RP Gain 1dB - Active when there is a contact closure on programmable input.
• Dec Input RP Gain 1dB - Active when there is a contact closure on programmable input.
• Analog Output RP Gain Control - Active when the gain is in the upper half of range.
• Inc Output RP Gain 1dB - Active when there is a contact closure on programmable input.
• Dec Output RP Gain 1dB - Active when there is a contact closure on programmable input.
• Recall Memory Preset - Active when the preset controlled by the programmable input is the
current preset.
• Toggle Mute Inputs - Active when the audio inputs controlled by the programmable input are
unmuted.
• Toggle Mute Outputs - Active when the audio outputs controlled by the programmable input
are unmuted.
• Toggle Mute Crosspoints - Active when the matrix crosspoints controlled by the program-
mable input are unmuted.
• Momentary Mute Inputs - Active when the audio inputs controlled by the programmable
input are unmuted.
• Momentary Mute Outputs - Active when the audio outputs controlled by the programmable
input are unmuted.
• Momentary Mute Crosspoints - Active when the matrix crosspoints controlled by the
programmable input are unmuted.
• Run a Macro on Close - Active when there is a contact closure on programmable input.
