What it does

When one horn per PA telephone is not enough. EXA-I adds a 100 W RMS amplifier to a SMART PA telephone and feeds more loudspeaker horns through line transformers. The number of speakers you need decides the amplifier you choose.

Part of a system

Plant PA system

Paging and private talk across a whole plant, in two architectures. MCS-II puts a 30 W amplifier in every PA telephone and needs no amplifier rack; MCS-III keeps line-powered phones in the field and drives 100 V loudspeaker lines from central 250 W amplifiers.
