The STS-K003 speech transfer systems provides assistance for clear communication where normal speech is impaired by use of glass, a security screen or other similar barriers.

Description

The STS-K003 speech transfer systems provides assistance for clear communication where normal speech is impaired by the use of glass, a security screen or other similar barriers.

An under-the-counter hearing loop is included with this system which provides additional assistance for hearing device wearers. The presence of the induction hearing loop makes the STS system compliant with 2010 ADA standards related to 1:1 communication for people with hearing loss.

Features
Energy-saving “green” standby mode is automatically used, achieving a power saving of up to 80%
Advanced audio processing features Automatic Gain Control (ACG), compression, and noise gate
Constant-current Loop drive (with engineer adjustable loop drive level)
Isolated audio line input/output allows additional ohmically isolated line level audio input or output to recording system (factory options, not available together)
LED column indicator aids adjustments and indicates power and status
Continuous self-testing means that no specialized equipment is required to confirm functionality
DC Power: 2.1mm DC jack
Power and status indication: Green/red LED column
