3.Application

The ZMX8210 is a user-friendly rack mixer which is principally used for fixed 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.

3.1Examples of application

In comparison to conventional rack mixers, the ZMX8210 offers several advantages for fixed installations and PA equipment that is being used by laymen. With the Euro-type connectors and the easy usability, the ZMX8210 optimally fulfills the requirements of these kind of applications.

3.1.1 Directing public address to up to three zones

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).

3.1.2 Using multiple ZMX8210s

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:

1)Set one unit to master mode and the second to slave mode by using the SLAVE/MASTER switch [22].

2)Using a shielded, 4-pin conductor cable to connect the BUS

LINKS connector of the MASTER unit to the corresponding connector of the SLAVE unit.

3.1.3 Remote control of the ZMX8210

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.
