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 a good idea to have a clear installation plan. To 

create your installation plan, you need to consider sev-

eral design parameters including what sound sources 

will be used, if announcement paging in necessary, 

which rooms need to have sound, if remote volume 

control is required, which type of speakers will do the 

best job for the room they are covering, and your wir-

ing 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 S zone is ideal. The S zone 

provides four 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 

S zone also has a special Ducking feature so when you 

speak into the microphone, the volume of the music 

is automatically lowered. You can connect line level 

signals on all four input channels, so signals from TAPE, 

CD, DVD or Karaoke 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. For example, in a 

small to medium size restaurant, you may want back-

ground music from a CD in one room, Disco Karaoke 

in another room, the ability to have a hostess paging 

parties for their tables and a cook paging a waitress to 

pick up an order. The Samson S zone can accomplish 

all of this easily.

Creating the Audio Zones

You can create separate audio environments using up 

to four S zone’s outputs, each connected to the input 

on the SZ series amplifier. You can connect one or 

more speakers with a total load impedance of 4 ohms 

or more to the SZ Series amplifier's output.  Obviously, 

(or perhaps not so obviously) we call an output a zone 

on the S zone, but a zone is also the area where you 

want to have sound. So, think about where you want 

to distribute the sound.  The SZ Series amplifiers and S 

zone can accomplish all of this easily. In addition, the 

S zone let’s you easily connect a remote control level 

for each of the zones, so you can control the volume 

in the room even if the audio equipment is located 

somewhere else.
