GAIN

This command changes or reports back the input gain for a channel. The command supports all inputs, outputs, and subbuses.

[DEVICE] GAIN <CH> <W> <X> [<Y>]

Explanation

<CH>

CH= 1-8 Parameter to apply to select the microphone channel

CH= A-D Parameter to apply to select the line channel CH= 1-2 Parameter to apply to select the subbus channel

CH= * Parameter to apply command to all microphone channels

<W>

W=S Parameter to set subbus

W=I Parameter to set input

W= O Parameter to set output

<X>

X=-20–20 Parameter to set the level

X=Null Parameter to return the current level

<Y>

Y=R Parameter to indicate relative

Y=A Parameter to set the level absolute

Y= Null Parameter will default to R (relative)

Return Values

The command will return the updated level of the channel in the same format as the command. The level returned is always absolute.

Examples

The following command lowers the gain 3dB on microphone input channel 2. This command applies only to the box the serial The following is returned out the serial port indicating cable connects to since the device is not specified: an updated gain value:

GAIN 2 I -3 GAIN 2 I -12

GATE

This command reports back the microphone gating status of an AP800. This command is read only.

[DEVICE] GATE

Return Values

The command will return the current status of microphone gating for a given unit with a hex value.

Example

The following command requests the gate status from device

14:#14 GATE (When this command was issued, mics 1, 4, and 7 were gated on.)

The following is returned out the serial port, indicating an updated gate value: #14 GATE 49
