The MZD 8000

The MZD 8000 digital module is an AES 42 A/D converter for all
microphone heads of the MKH 8000 series.

The MZD 8000 has the following features:

• Direct screw-on connection for the
microphone heads of the MKH 8000 series

• 2-channel 24 bit A/D converter,
dynamic range 115 dB

• Studio grade preamplifier and converter

• Sampling rate 44.1 kHz, 48 kHz, 88.2 kHz,
96 kHz, 176.4 kHz and 192 kHz

• Integrated, remote-controllable DSP functions such as
low-cut filter, attenuation and gain

• Digital output in AES 42 format

• External synchronization via AES 42, Mode 2

Putting the digital module into operation



쐋

Connecting the microphone head and
the cable

왘 Screw an MKH 8000 series micro-

phone head to the connection  of
the MZD 8000 as shown.

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.

왘 Only connect the digital module to microphone

inputs and power supply units which supply
phantom power according to the AES 42 standard.

Note:

During operation, the MZD 8000’s connection for the micro­phone head provides 48 V phantom power.

왘 First screw on a microphone head before connecting an XLR

cable.

To connect the cable:

왘 Connect 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

5

supply voltage and a deterioration in jitter characteristics, espe-

cially at high sampling rates.

왘 If possible, use a continuous cable to connect the microphone

and the subsequent device.

왘 For longer cable distances, only use AES/EBU cable.

Connecting the digital module to other devices

A

B

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:

왘 Use a format converter for conversion into other signals (B).

For additional information, visit the Internet at www.aes.org.

왘 Synchronize all devices of the digital signal chain.

6

To connect the microphone:

왘 Use a suitable cable to connect the MZD 8000 to the micro-

phone input of a format converter or a mixing console.

왘 When connecting the cables, make sure that the connectors

are properly locked.

Remote controlling the MZD 8000

Via the AES 42 interface, you can make the following settings to
the MZD 8000.
Depending on the software or the format converter used, some
settings are possibly not supported.
For information on software updates, visit the Internet at
www.sennheiser.com.
