Selects either the Programmable Inputs or the Programmable Outputs notebook.
Selects on of the 11 programmable inputs or 8 programmable outputs for setup.
Programmable Input Function Select: Selecting a function type from the Function list
causes the controls used to setup the specific feature or features of that function to appear
in below the list. These feature(s) vary according to the nature of the programmable input
function values.
When certain functions have been selected and the control panel is connected to a
DMTH4, the Test button is enabled. Pressing this button simulates a contact closure on the
programmable input and is very useful for testing the function. The following function types
are available:
Analog Input RP Gain Control (AI): 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 audio input channel gain range is
controlled by the Rear panel input gain controls.
Inc Input RP Gain 1dB (II): Increments the rear panel gain of one or more audio inputs
in response to a contact closure. Normally used with a momentary contact switch. The
audio input channel gain range is controlled by the Rear panel input gain controls.
Dec Input RP Gain 1dB (DI): 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 audio input channel gain range is controlled by the Rear panel input gain
controls.
Analog Output RP Gain Control (AO): 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 programmable
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 audio input chan nel gain range
is controlled by the Rear panel input gain controls.
Inc Output RP Gain 1dB (IO): Increments the rear panel gain of one or more audio out-
puts in response to a contact closure. Normally used with a momentary contact switch.
The audio input channel gain range is controlled by the Rear panel input gain controls.
Dec Output RP Gain 1dB (DO): Decrements the rear panel gain of one or more audio
outputs in response to a contact closure. Normally used with a momentary contact
switch. The audio input channel gain range is controlled by the Rear panel input gain
controls.
Recall Memory Preset (MP): Initiates the loading of a memory preset in response to a
contact closure. Normally used with a momentary contact switch, and can be applied
to any one of the memory presets stored in the DMTH4 memory.
Toggle Mute Inputs (MI): Toggles the mute status of one or more audio inputs in re-
sponse to a contact closure. If muted, a contact closure unmutes the channel and vice
versa. Normally used with a momentary contact switch and can be applied to any
combination of audio input channels.
Toggle Mute Outputs (MO): 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. Normally used with a momentary contact switch, and can be applied to any
combination of audio output channels.
