 NTI TalkBox greatly simplifies the acoustical feed of the STI-PA intelligibility test source signal into closed reinforcement systems. It presents the standardised voice-like acoustical signal emission simulating a human talker according to IEC 60268-16, combined with a TNO certified speech intelligibility signal at standardised levels. The built in combination of solid-state generator and DSP ensures the highest playback accuracy and lowest sample frequency deviations with minimised jitter effects. NTI TalkBox features human head-like dimensions and is based on a Solid-State-Generator with CF-card. It perfectly equalises the STI-PA test signal and replays it at the precisely correct playback sampling rate, also minimising systematic errors throught the internal amplifier and precision loudspeaker.

If you require a full 12 months certificate, the unit will be ordered from the NTI factory and not supplied from stock. |
