Colored LEDs (not Amber) indicate the 9305 module is in Normal Mode.
Ports 1, 2, 3, 18, 19, 20, 33, 34, 35, 36:
Solid Green LEDs indicate input data is present, carries pcm data and is near rate to reference
Ports 6 & 7:
Solid Blue indicates non-audio data is present, carries non-pcm data and is near rate to reference
Port 15:
Solid Red indicates input data is present, carries pcm data, is near rate to reference but has errors
(parity, or status CRC or bi-phase encoding)
6.3.1.3 HEADPHONE
MONITORING
A headphone socket on the right hand side of the module allows the user to monitor any of the inputs
(selected using Input Monitor Mode – described in Section 6.3.1.2).
The headphone volume is limited for safety reasons (approximately -10dB). This limited level can be
defeated by holding down the push button labeled HP Limit. The LED, normally green, will indicate when the
headphones are at full volume by turning red.
If a non-audio source (indicated by blue LED) is selected in Input Monitor Mode the headphone output will be
muted and cannot be defeated.
