Operating The ZM Series
Pre Announcement Chime
The ZM series mixer offers a useful Chime function to alert
listeners of an upcoming page. Simply press the front panel
Chime switch to play the chime.
In addition, the ZM series mixer can be set for one of four
selectable Chime tones by moving the internal shorting
jumpers as show in the figure below:
Priority Control
Channel 1 and 2 can be set for Priority operation. When
microphone channel 1 and 2’s Priority switch is set to the “ON”
position, the other input channels will mute whenever signal
is present on the microphones connected to Channel 1 and 2.
Priority Mic Muting
In addition to the priority muting on microphones connected
to Channels 1 and 2, there are three levels of priority muting
which is always active. The priority muting is set in three
groups in the following order.
Chime and Tele page
Remote Mic
Channels 1 through 6
This means if there is a Tele-page or the Chime switch is
pressed, the Remote Mic and input Channels 1 through 6
are muted. If there is a signal on the Remote Mic, Channel
1 through 6 will be muted. The signals in the same priority
group will stay on together.
Connecting the Input Sources
Next, make the signal input connections, using the Euroblock
input connectors on the rear panel. If your mixer has balanced
outputs, we recommend the use of three-conductor cabling
and connectors (unbalanced two-conductor connections
can also be used, but you’ll get better signal quality and less
outside noise and hum if you use balanced lines).
On the front panel of the ZM Series, turn all the Channel input
controls fully counterclockwise (to their “MIN” setting). Then
connect the supplied heavy-gauge 3-pin “IEC” cable to the rear
panel IEC connector and to any grounded AC socket.
Press the front panel Power switch in order to turn on the ZM
Series. The Power LED will light and the Protection LED will go
on. After approximately five seconds, the Protection LED will
go off (you’ll hear a click when this occurs).
Apply an input signal to the ZM Series at or about +4dBu. Now
set the channel level to about half way up.
While the input signal is present, slowly raise the Master level
control until the desired sound level is achieved.
The SIGNAL and PEAK LED indicators will show you the
continuous power output of the ZM Series as signal is being
passed. For the best signal-to-noise ratio, the ZM Series
should normally be run with the Master level control at or
near maximum (fully clockwise, at the “MAX” position) and the
PEAK segments should light occasionally (but not frequently)
during peak levels. If the signal is too loud, use the Input level
controls attenuate the signals as necessary to achieve the
desired speaker level.
