Designing an Installation Plan
If you are a professional installer, you’ll probably want
to skip over this section, however if you are setting
up your system for the first time, this section can help
make your installation a little bit easier.
Before you start plugging, stripping and connecting
wires, it is a good idea to have a clear installation plan.
To create your installation plan, you need to consider
several design parameters including what sound
sources will be used, if announcement paging in nec-
essary, which rooms need to have sound, if a remote
paging mic is required, which type of speakers will do
the best job for the room they are covering, and your
wiring plan.
Selecting the Sound Sources
If you are using multiple sound sources, you'll need
some type of mixer and for fixed installations, a zone
mixer like the Samson ZM series is ideal. The ZM series
provides six input channels with the ability to con-
nect up to six input sources. On input Channel’s 1 and
2 there is an input for connecting microphones with
phantom power to operate condenser type mics. The
ZM series also has a special priority feature so when
you speak on the microphone, the music is automati-
cally muted. You can connect line level signals on four
input channels, so signals from TAPE, CD, DVD or Ka-
raoke players, Audio/Video TV monitors, Radio Tuners,
DJ mixers or any other line level device can be used as
a sound source. You may also be able to connect the
output from a Home Hi-fi receiver if it’s equipped with
a line level output.
Creating the Audio Zones
You can create separate audio environments using up
to five ZM series’s outputs, each connected to an input
channel on the ZM75 or ZM125 amplifier. You can
connect one or more speakers with a total load imped-
ance of 4 ohms or more to each output of the ZM Se-
ries amplifier. Obviously, (or perhaps not so obviously)
we call an output a zone on the ZM series, but a zone
is also the area where you want to have sound. So,
think about where you want to distribute the sound.
The ZM series can accomplish all of this easily. In ad-
dition, the ZM series let’s you easily connect a remote
microphone for paging.
