The front edge of the card provides LED indicators are provided to monitor power rails,

input presence/silence, input sample rate and local/remote mode.

The following table summarises the card edge LED functions and colours:

Name

LED Colour Description

+5V and 18V

Green

Illuminates when on-board power is OK

Ref

Red

Illuminates when either video or word clock is selected but no
valid reference input is present

Rem

Yellow

Illuminates when board has been last accessed by remote control

Sil1

Yellow

Silence detected on input 1

Sil2

Yellow

Silence detected on input 2

48k, 44k, 32k

or Auto

Yellow

Sampling Frequency (32, 44.1, or 48 kHz) or Automatic AES
Reference Mode (for 30-50kHz)

Status is also available using an active control panel and Statesman control. Please refer

to the appropriate chapter for further information.

Basic fault finding guide

The Power OK LEDs are not illuminated

Check that the frame PSU is functioning – refer to the appropriate frame manual for

detailed information

There are no audio outputs

Check that the silence threshold delay is not set to low

Check that functioning digital audio output sub-modules are fitted securely

Check that any audio cabling is intact

The audio output lacks high frequency content

Check the Low Pass Filter setting available under Options on a remote or front panel LCD

control.
