EAW DX8 instruction manual Logic Inputs, Logic Outputs

The logic functions assigned to each individual logic input and output are configured using the DX8- PC application. In addition, each logic input and output can be assigned a descriptive name (up to

32 characters) for easier identification within the PC application.

Note: Logic I/O functions are set from the PC application only.

Logic Inputs

The following functions can be activated by the logic inputs:

Force On

Force Off

Input Mute

Output Mute

Group Mute

Preset Recall

Force-on/Force-off

This provides a means to temporarily increase or decrease the gain of a channel with an external switch, remote control, or through the priority function. This is defined in the Audio Input window in the DX8-PC software application. These are momentary functions and are active only when the logic input pin is active (held low). It forces the input fader level to the Force On Level or Force Off Level selected for that channel.

See “Audio In” on page 25 for more information about the Force-on and Force-off function.

Mute

An input, output, or group can be muted with a Logic Input. This function can be activated in one of four ways:

•Momentary: The mute/enable function is continuously active while the logic input is continuously active.

•Latch On: The mute function is activated when the logic input goes from inactive to active.

•Latch Off: The mute function is deactivated when the logic input goes from inactive to active.

•Toggling: The mute function toggles its state when the logic input goes from inactive to active.

Preset Recall

This function can be activated as a momentary function or as a latching function. When activated as a momentary function, the preset state is recalled only when the logic input is active. When the logic input is inactive, the DX8 returns to its base state as long as no other momentary function is in force. Normally, the base state is the state the DX8 was in prior to activating the preset state.

When activated as a latching function, the preset state is recalled when the logic input goes from inactive to active. See “Presets” on pages 22 and 29 for more information about the preset recall function.

Logic Outputs

The logic outputs indicate the state of the following conditions, selectable in software:

Input Signal Present

Output Signal Present

Input Channel Open

Output Channel Open

Preset Active

Priority Inactive

Auto-gate Status

Signal Present

A logic output can indicate whether a signal greater than –40 dBFS is present on an input or an output. Select the channel from the DX8-PC application.

Channel Open

A logic output can indicate when a channel or mix output gain is greater than –40 dBFS. For an input, this includes either the Bus A or B mix level. For the output, it is either the A or B mix output. Select the channel from the DX8-PC application.

Preset Active

A logic output can indicate when a particular preset is active. Choose the preset indicated by the logic output from the DX8-PC application.

Priority Inactive

A logic output can indicate whether an Input Force-on Priority is active, as selected from the DX8-PC application.

Auto-gate Status

A logic output can indicate when an Input Gate is active. Auto-gate is selected in the Automix window (see "Automix" on page 24 for more information about the Auto-gate function).
