TECPRO Loudspeaker station LS351

Description

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.

• Hands-free or headset operation
• Loudspeakers selected for clear voice reproduction
• Built-in flush-mounted electret microphone
• Microphone On/Off button offers push-to-talk or latching characteristics
• Acoustic feedback cancellation preset
• Side-tone preset for headset
• XLR 4-pin input socket for gooseneck microphone or headset
• Single and dual-circuit versions available on some models
• DC and 20kHz ‘Call Alert’ signaling send and receive
• 24kHz ‘Remote Mic Kill’ send and receive
• 28kHz ‘Override’ signal recognition for preset volume restoration

This has an 80mm loudspeaker and an electret microphone. Construction is based around a rigid aluminium extrusion with ABS side panels. The microphone, loudspeaker and associated controls are mounted on a machined top plate.

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. Dimensions: 245 x 120 x 90 (l x w x h) mm. Weight: 1150g.
