3.3.3 Explanation of Menu Parameters

by channel

Parameters so marked can be set for either Channel 1, Channel 2 or both channels together.

{STATUS}

MODULE: displays the status of the different board alarms.

FPGA FAILURE

Faulty programmable component.

REAR PANEL ERROR

Indicates an absence of the rear panel or an incompatibility between the module and the rear

panel. The STATUS led turns on flashing red.

INTERNAL

No valid reference signal connected.

EXTERNAL

The signal connected at the rear BNC is selected as reference for the card.

FRAME

The internal frame signal is selected as reference for the card; for Assy# 0696-1200-2xx only
the JP1 jumper has to be set accordingly with the reference generator card installed in the
Densité frame.

CARD EDGE

The signal coming from an adjacent module via the rear panel is selected as reference for the
card (only when used with the AMX-1101 rear panel).

CHANNEL (1/2):

displays the status of the corresponding analog input channel.

OVERLOAD (L/R)

Indicates an internal signal level higher than –0.5 dBFS.

MUTE (L/R)

Indicates a muted channel.

TONE

indicates the tone generator is active.

NO SIGNAL (L/R)

Indicates an internal signal level lower than the selected threshold during a user-defined
period.

ALL OK

indicates an absence of alarms.

{TONE}

by channel

Activates the tone generator. The internal tone generator provides a 1 kHz (- 18 dBFS) sine wave. The EBU mode
provides channel identification: left channel is cut off for 250 ms every three seconds.

{LEVEL}

by channel

Adjust the input level. This adjustment is made within a range of -96 dB to +12 dB in 0.5 dB steps. The default value is
0 dB.

{MUTE}

by channel

A mute command starts with a soft mute, followed by an AES silence. Automatic mute is performed on non-audio or
non valid samples.

{0dBFS SETTING}

Enables the selection of the RMS value of the input sine wave voltage associated with the digital full scale 0 dBFS.

{OUTPUT SAMPLE RATE}

Selection of the output sample rate.

{OUTPUT WORLD LENGTH}

by channel

Selection of the quantization value.

{CHANNEL STATUS}

by channel

ORIGIN

“origin” signal message (4 ASCII characters).
