TECPRO LS351 Loudspeaker station, Single circuit

Tecpro Communication system – Talkback loudspeaker stations

The LS351 derives power either directly from the 24V DC Tecpro line, or from an optional external 24V PSU. A green LED indicates power is present. Connection to the intercom system is via a pair of 3-pin XLR connectors which allow the LS351 to be ‘daisy chained’ with other user stations.

Series 2 Tecpro LS300 Loudspeaker Stations provide local monitoring of intercom circuits without the need to wear headphones. The built-in microphone makes them suitable for hands-free operation, allowing full-duplex simultaneous talk and listen conversations to take place. If required, a headset may be plugged in, disabling the internal microphone and speaker. LS300 Loudspeaker Stations offer single circuit operation as standard. Dual circuit versions are available on some models.
