8.1 MADI INPUT

The button INPUT sets the input to optical or coaxial. The section INPUT STATE helps to avoid

errors caused by wrong, missing or not correctly connected inputs, and makes handling the

digital MADI format much easier. A total of 38 LEDs display the state of the current input signal.

The SYNC LED lights up as soon as a valid signal is present at the input. An un-synchronous

input signal will be signalled by flashing of the SYNC LED. A missing or invalid input signal will

cause the ERROR LED to light up.

Audio data present in the input channels is signalled by one AUDIO LED per stereo channel.

The green LED is lit as soon as one of the channels of an 2-channel block contains audio data,

that is no longer digital zero.

64-channel and 96k frame format are displayed by one LED each. With those LEDs off, the

input signal is 56-channel and 48k frame format.

8.2 MADI OUTPUT

The buttons FRAME and FORMAT configure the MADI output signal as follows:

FRAME: 48k or 96k frame. 48k frame can be used with Single, Double and Quad Speed. 96k

frame is limited to the range 64 kHz to 96 kHz (Double Speed).

FORMAT: 56-channel or 64-channel format.

8.3 AES

The INPUT STATE of the 32 inputs is displayed by a total of 67 LEDs.

Each input has its own SYNC LED. If a valid input signal is applied, SyncCheck is active auto-

matically. SyncCheck takes the chosen clock (internal, external, etc.) as reference and com-

pares it with the input clocks. Inputs which are not synchronous will be signalled by flashing of

the corresponding SYNC LED.

An AES/EBU or SPDIF signal in the range of 60 kHz to 100 kHz will turn the DS (Double

Speed) LED on. An AES/EBU or SPDIF signal in the range of 162 kHz to 200 kHz will turn the

QS (Quad Speed) LED on.

The AUDIO LEDs light up as soon as the digital signal carries information other than digital

zero. The channel doesn't matter. So there is only one channel of audio information necessary

for the LED to light up. The amount of level is not indicated.
