Application3.
The ZMX8210 is a user-friendly rack mixer which is principally
used for xed installations to direct public address in different
zones or facilities, such as cafés, practices and houses of wor-
ship. With one unit, you can provide a maximum of three zones
with different signals.
In case you need to use further signals, simply link to units to-
gether. The ZMX8210 can handle line-level sources, dynamic
microphones and phantom-powered capacitor microphones as
input signals.
Examples of application3.1
In comparison to conventional rack mixers, the ZMX8210 offers
several advantages for xed installations and PA equipment that
is being used by laymen. With the Euro-type connectors and the
easy usability, the ZMX8210 optimally fullls the requirements of
these kind of applications.
Directing public address to up to three zones3.1.1
The following application example shows a typical cabling of three
zones in mono mode. Distribute the signal to zones 1 – 3 by using
the routing switches (L, R, AUX) of the particular input channel.
Instead of three independent mono zones, it is also possible to
have one stereo zone (LEFT / RIGHT bus) and one mono zone
(AUX bus).
Using multiple ZMX8210s3.1.2
In case the eight input channels of the ZMX8210 are not enough,
you can link two units together by using the BUS LINKS connec-
tors. The output buses of the two units are connected by routing
the input signals of both units to the output buses. This gives you
additional inputs.
The output signal can be on both units. To use two units together,
please complete the following steps:
Set one unit to master mode and the second to slave mode 1)
by using the SLAVE/MASTER switch [22].
Using a shielded, 4-pin conductor cable to connect the BUS 2)
LINKS connector of the MASTER unit to the corresponding
connector of the SLAVE unit.
Remote control of the ZMX82103.1.3
The ZMX8210 provides a 5-pin REMOTE connector to remote
control
the volume level of the LEFT and RIGHT buses. =
channel selection of channels 7 and 8. =
The remote control can be realized by using simple compo-
nents.
Volume level of the LEFT and RIGHT buses
To be able to remote control the volume level of the LEFT and
RIGHT buses, you need a potentiometer. Use a
10 kΩ potentiometer to achieve a maximum attenuation of =
30 dB.
100 kΩ potentiometer to achieve a maximum attenuation of =
60 dB.
