To listen to an analog input on the phones output:
1. Ensure that the output volume is adequate (see
Adjusting the Headphone Volume
2. Press the button next to the corresponding channel to open the channel settings.
3. Use the fourth button to send this channel to the Phones Output (left and right) The button turns
green, indicating that temporary routing has been established. The green button is also shown on the
main screen and in the phones output settings.
To remove the temporary phones routing:
• Deactivate the routing by either pressing its button in the corresponding input channel, or
• by opening the phones output and deactivating the mode there. If there was a previous routing, it will
be re-established immediately.
9.2. MADI Input
The AVB Tool accepts up to two MADI signals, one electrical (BNC input) and one optical via SFP option
(LC input).
To connect a MADI signal:
1. Ensure that you have set the correct sample rate and clock source in the
CLOCK
section.
2. Connect the cable to the corresponding input.
3. Open a
MADI
tab in the input section to see the current LOCK and SYNC state.
9.2.1. MADI at High Sample Rates
The MADI standard (AES10) allows transport of audio at sample rates beyond 48 kHz by reducing the
number of available channels.
Double speed (88.2 kHz, 96 kHz)
Double speed audio signals can be transmitted and received in two different ways. Manufacturers can
implement one or both modes, usually referred to as "96k frame" and "S/MUX 2" or "legacy" mode. It is
important to use the same mode on both sender and receiver side because S/MUX 2 and legacy mode
are not compatible. Both modes transport the audio signal transparently.
96k frame
The so-called "96k frame pattern" (AES10) can be detected at the receiver side automatically. In this
mode, the frame numbers and corresponding user bits equal the number of channels submitted. The "56
Ch." setting corresponds to 28 audio channels at 88.2 kHz and 96 kHz sample rates. The "64 Ch." setting
