Output

The Output function controls the output levels from the unit.

Using the Stereo Control

This button controls the tracking of the Gain/Attenuator levels. If the LED is gray, then the two channels do not track each other. If the LED is blue, then the channels will track each other. Clicking on the button will toggle the setting.

Mute Control

This button determines if the output signal will be muted. A gray LED indicates that the signal is not muted, while a red LED indicates that the signal is muted. Clicking on the button will toggle the setting.

Using the Relay Control

This button activates and deactivates the output relays. A gray LED indicates that the audio path is not complete. A green LED indicates that the audio path is complete. Clicking on the button will toggle the setting.

Gain

To change settings, click on the arrow next to the number in the text box. A selection list will appear. The list may or may not be scrollable. Click on the desired entry to make a selection.

Digital I/O

In Mute (RX)

Mutes the AES receiver data stream.

Out Mute (TX)

Mutes the AES transmitter data stream

Pass Through

Routes the input from the receiver directly through the transmitter to the card’s output (the output data from the DSP is bypassed). Either the In-Mute or Out-Mute will mute the output when Pass Through is on. Data may still be received when Pass Through is on. Pass Through is only valid with a 48 kHz bit stream, or with a non-48 kHz bit stream and Sample Rate conversion enabled. A non-48 kHz sample rate with no sample rate conversion will result in an error when the Pass Through option is selected.

SRC

Clicking on the SRC button turns on the Sample-Rate-Converter. The SRC is used to convert non-48 kHz data streams into 48 kHz data streams compatible with the ISP-100.

Note: Turning on the SRC will result in a 20-bit output data stream except in the case of Pass Through.
