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 on 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 and have 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 an input 

channel on the SZ240 or SZ480 amplifier. You can con-

nect one or more speakers with a total load imped-

ance of 4 ohms or more to each output of the SZ series 

amplifier.  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.
