Bedrock Talkbox Speech Tester (BTB65) for STIPA Compliance Testing

The BTB65 can be used as an electronic signal source by utilizing the line-out connection. Or it can be used as a calibrated acoustic signal source, due to its integrated loudspeaker. The TalkBox is designed to accurately play the STIPA test signal, as well as several other test signals. The device features an interactive LCD touchscreen which allows you to easily control all features and monitor its settings at a glance.

STIPA = Speech Transmission Index for Public Address Systems.

• Touchscreen front panel. The user interface of the BTB65 shows virtually all buttons and controls on a single screen, allowing you to monitor the status of the device at a glance.
• Plays STIPA test signals (according to IEC-60268-16 rev4-2011 and draft rev5-2016).
• Play noise (pink, white) and sine waves (125 to 8000 Hz).
• Plays back calibrated speech signals, to announce the beginning and end of tests and to obtain a subjective impression of speech intelligibility while testing (male and female speech, in US, UK, SP, FR, GE or NL).
• Signals are played back with automatically calibrated spectrum and level (no user calibration needed - optional adjustment of nominal level).
• Can also be used as an electronic signal source through the featured line-out jack.
