This chapter describes the front panel of the DN9650 and DN9652 units, which 
comprise the following.

Ventilation grill   Air intake for internal 
cooling via an internal fan.  Do not obstruct.

N/A

CONTROL section   A green ETHERNET LED 
illuminates to show the communication status 
between unit and PC, as follows:

• Illuminated = traffic detected.

• Extinguished = no traffic detected.

AES50 AUDIO section (DN9650 only)   
Three sets of LEDs provide status information 
for the three AES50 audio connectors.  The 
green OK and red ERROR LEDs per set show 
the following:

• Pulsating green with red extinguished = 

synchronised and with audio activity.

• Green extinguished with red illuminated = 

loss of synchronisation and no audio 
activity.

ASYNCHRONOUS SAMPLE RATE 
CONVERTER section (DN9650 only)   This 
section shows the status of the configured 
clock source, which can be AES50 output, 
ASRC or network output.  Each source has a 
yellow ENABLED LED, which illuminates to 
show that the source is enabled.  The DN9650 
also has the facility to stop the output clock if 
the input clock fails.  This condition is indicated 
by the illumination of the red STOPPED LED.

For the LED status, see Table 1 “DN9650 ASRC 
LED status” on page 13.
