Description
programmable input. The tabs along the bottom of the notebook are used to select one of the
programmable inputs for setup.
To set up one of the programmable inputs, 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
programmable input function values. The following function types are available:
• Analog Input RP Gain Control (AI) This function controls the rear panel gain of one or more
audio inputs in response to changes in voltage applied to the programmable input. Normally
this function is used by connecting the wiper of a potentiometer to the programmable input so
that it acts as a "volume control" for the audio input channels that the function applies to. The
voltage may vary from 0 to 5 VDC. The range over which the gain of the audio input channels is
allowed to vary is controlled by the Rear panel input gain controls described below. This
function can be applied to any combination of audio input channels.
• Inc Input RP Gain 1dB (II) This function increments the rear panel gain of one or more
audio inputs in response to a contact closure. This is normally used with a momentary
contact switch. The range over which the gain of the audio input channels is allowed to vary
is controlled by the Rear panel input gain controls described below. This function can be
applied to any combination of audio input channels.
• Dec Input RP Gain 1dB (DI) This function decrements the rear panel gain of one or more
audio inputs in response to a contact closure. This is normally used with a momentary
contact switch. The range over which the gain of the audio input channels is allowed to vary
is controlled by the Rear panel input gain controls described below. This function can be
applied to any combination of audio input channels.
• Analog Output RP Gain Control (AO) This function controls the rear panel gain of one or
more audio outputs in response to changes in voltage applied to the programmable input.
Normally this function is used by connecting the wiper of a potentiometer to the program-
mable input so that it acts as a "volume control" for the audio output channels that the
function applies to. The voltage may vary from 0 to 5 VDC. The range over which the gain of
the audio output channels is allowed to vary is controlled by the Rear panel output gain
controls described below. This function can be applied to any combination of audio output
channels.
• Inc Output RP Gain 1dB (IO) This function increments the rear panel gain of one or more
audio outputs in response to a contact closure. This is normally used with a momentary
contact switch. The range over which the gain of the audio output channels is allowed to
vary is controlled by the Rear panel output gain controls described below. This function can
be applied to any combination of audio output channels.
• Dec Output RP Gain 1dB (DO) This function decrements the rear panel gain of one or
more audio outputs in response to a contact closure. This is normally used with a momen-
tary contact switch. The range over which the gain of the audio output channels is allowed
to vary is controlled by the Rear panel output gain controls described below. This function
can be applied to any combination of audio output channels.
• Recall Memory Preset (MP) This function initiates the loading of a memory preset in
response to a contact closure. This is normally used with a momentary contact switch, and
can be applied to any one of the memory presets stored in the DM84 memory.
• Toggle Mute Inputs (MI) This function toggles the mute status of one or more audio inputs
in response to a contact closure. If muted, a contact closure unmutes the channel, and vice
versa. This is normally used with a momentary contact switch, and can be applied to any
combination of audio input channels.
• Toggle Mute Outputs (MO) This function toggles the mute status of one or more audio
outputs in response to a contact closure. If muted, a contact closure unmutes the channel,
and vice versa. This is normally used with a momentary contact switch, and can be applied
to any combination of audio output channels.
• Toggle Mute Crosspoints (MX) This function toggles the mute status of one or more
matrix crosspoints in response to a contact closure. If muted, a contact closure unmutes
the crosspoint, and vice versa. This is normally used with a momentary contact switch, and
can be applied to any combination of matrix crosspoints associated with one particular
audio input channel.
