Should this product be used in an electromagnetic eld that is amplitude
modulated by an audio frequency signal (20 Hz to 20 kHz), the signal to
noise ratio may be degraded. Degradation of up to 60dB at a frequency
correspondingto the modulation signal may be experienced under extreme
conditions (3V/m,90% modulation).
2.3 Connecting up
Connect up the unit(s) as required:
• AES50 cables from AES50-equipped device (for example, a console) to rst
DN9620.
• Optical/copper snake from rst DN9620 to second DN9620.
• AES50 from second DN9620 to other AES50-equipped device (for example,
an I/O unit).
• Mains power IEC connectors to both DN9620s.
For an example, see section 5 - Connections.
2.4 Powering the unit on/o
Switch on the mains on/o switch of both DN9620s (rear panel). The blue
