The six zone system configuration uses two quad 120 Watt amplifiers. The design utilises 100 volt line technology.

At the heart of the system is the 8 zone matrix unit to route the music and paging signals to the selected zones.

On the front panel, for each zone, are music source selector switches a music volume control and a preset paging volume control. If required the mixer could be connected to the fire alarm system so that the music signals can be muted when activated.

The client required a number of local systems so that these areas could play different music to that of the main system. We felt this would not be cost effective and suggested installing facility panels. These panels would offer flexibility and prove more cost effective. The Facility panels are connected to the main control equipment thus separate/local amplifiers are not required. The panels offered the provision of a local music and microphone input so that a local music source connected to the panel would play music over the loudspeakers in the local areas only. However, should the main system broadcast an announcement the local music would mute until the broadcast has finished.

The level of paging is set at the zone amplifier and then the level of music is set using the matrix music level control. Music broadcasts will only be muted in the zone or zones paged, other zones remaining unaffected. Note that for the basketball hall, there are two amplifiers, one for each side of the hall. Thus the output levels on each side of the hall can be adjusted separately which would be particularly useful if there was a basketball competition. The side of the hall where the audience would sit could have an increased sound level compared with the other side.

There was also a requirement for R.N.I.D. Approved AFILS systems (Audio Frequency Induction Loop Systems). These loop systems where connect to the PA system so that broadcasts would be received by the hard of hearing.
