Putting the digital module into operation
Connecting the microphone head and
the cable
왘Screw an MKH 8000 series micro-
phone head to the connection of
the MZD 8000 as shown.
Note:
During operation, the MZD 8000’s connection for the micro-
phone head provides 48 V phantom power.
왘First screw on a microphone head before connecting an XLR
cable.
To connect the cable:
왘Connect an XLR cable to the XLR-3M
socket of the MZD 8000.
The XLR connection locks into place
with an audible click.
Long cables and multiple connectors in
the cable path lead to a drop in the
CAUTION! Danger of damage to the device!
An incorrect supply voltage can cause damage to the
power supply unit, the MZD 8000 and to subsequent
devices.
왘Only connect the digital module to microphone
inputs and power supply units which supply
phantom power according to the AES 42 standard.

supply voltage and a deterioration in jitter characteristics, espe-
cially at high sampling rates.
왘If possible, use a continuous cable to connect the microphone
and the subsequent device.
왘For longer cable distances, only use AES/EBU cable.
Connecting the digital module to other devices
The MZD 8000 digital module receives and transmits electrical
signals according to the AES 42 standard (A).
If your mixing console does not support the AES 42 standard:
왘Use a format converter for conversion into other signals (B).
For additional information, visit the Internet at www.aes.org.
왘Synchronize all devices of the digital signal chain.
