ULTRAZONE ZMX8210
Installation8
Connect the potentiometer to pins V and SHD. Connect the mid
tap to pin C (see Fig. 3.2).
Volume potentiometer

Alternatively, you can control the volume by using a positive con-
trol voltage of max. 11 V DC. The voltage needs to be inserted
between the pins SHD and C.
When using a voltage source to remote control the vol- +
ume level, make sure that the control voltage does not
exceed 11 V DC or else your unit could be damaged.
Selecting stereo channels 7 and 8
To select the stereo channels 7 and 8, you need a push-button
switch and optionally two LEDs.
Connect the push-button switch to pins SHD and SEL. You can
add two LEDs to indicate the selected channel. They have to be
connected in parallel with a reverse polarity between the pins IND
and SHD (see Fig. 3.3).

Basic operation3.2
Using the ZMX8210 is easy to learn and is very similar to using a
standard mixer. Complete the following steps:
Hook up the unit as described in Chapter 3.1.1)
Adjust the LEFT, RIGHT and AUX LEVEL knobs 2) [17] to center
position and turn the LEVEL knobs {5} of each channel fully
to the left.
Turn on the ZMX8210 and the other devices you want to use 3)
(amplier and loudspeakers last).
Apply an audio signal (line or microphone signal) to an input 4)
channel.
Press the +48 V push-button switch 5) {2} in case you want to
use a capacitor microphone.
Press the push-button switches L, R and AUX 6) {3} to select
the buses to which the input signals are sent.
Turn the LEVEL knob of the corresponding channel to the 7)
right until
you have reached the required volume level =
or the 0 db LED glows continuously. =
If the CLIP LED lights up, you need to adjust the level by slowly
turning the knob to the left. For especially strong input signals, use
the PAD push-button switch {1} to attenuate the signal further.
Repeat steps 4 to 7 with additional signal sources. Use chan-8)
nels 7 or 8 for stereo signal sources.
In case you are using a microphone, press the MIC LOW CUT 9)
push-button switch [11] to reduce low-frequency rumble such
as subsonic noise.
Press the EQ ON push-button switch 10) [14] and adjust the LOW,
LOW MID, HIGH MID and HIGH knobs of the equalizer section
(15) to modify the sound.
Use the LEVEL knobs of the LEFT, RIGHT and AUX buses 11)
[17] to adjust the volume level of the OUT L, OUT R and AUX
outputs (zones).

Rack mounting4.1
The unit requires the height of 1 U to t within a 19" rack. Please
make sure to provide approximately 4" of space for the connec-
tors on the rear panel. Please use M6 rack screws and nuts when
rack-mounting the unit.
Audio connections4.2
The ZMX8210 connections are Euro-type connectors. You require
special PCB connectors for the cabling. You can purchase the
connectors at well-assorted electronics retailers. The ZMX8210
connectors' pin assignment is printed on the rear panel of the unit.
Alternatively, refer to the following diagrams.
