Bedrock Elite - Model BTB115 -Advanced Talkbox: Acoustic Signal Generator for Testing

SHARE
The Bedrock BTB115 Advanced Talkbox is a versatile acoustic signal generator designed for precise audio testing. It supports various test signals, such as STIPA and full STI, which are crucial for assessing speech transmission index intelligibility. The device emulates a human speaker's directivity and characteristics, enabling users to establish a calibrated testing environment with ease. Key features include straightforward operation through three capacitive touch displays, which grant users control over the device from both the front and back. The intuitive menu structure allows for easy navigation, and remote control options via WiFi or Bluetooth add convenience. Additionally, the BTB115 offers a balanced line output for those requiring an electronic signal instead of an acoustic one. Its integrated laser distance meter ensures accurate microphone placement, enhancing measurement precision. Overall, the BTB115 Talkbox is a critical tool for audio professionals needing reliable signal generation for perceptual audio quality testing.

The Bedrock BTB115 advanced talkbox is an advanced acoustic signal generator that supports a variety of test signals, including STIPA and full STI. Designed to match a human talker in terms of directivity pattern and other characteristics, the BTB115 Advanced Talkbox removes the hassle out of creating a calibrated test setup.

 

The Bedrock BTB115 Advanced TalkBox offers the following features:

  • Playback of STIPA and full STI signals according to IEC- 61268 re 5 (2020).
  • Playback of noise signals (pink/white), g. for quick evaluation of frequency transfer functions.
  • Playback of sine waves and
  • Spoken messages for announcing the beginning and end of test sessions (also to be used to obtain a subjective impression of speech quality) in 6 languages (US/UK/FR/SP/GE/DU), each in a male and a female voice.
  • Playback of user-uploaded signals, calibrated on-the-fly through the powerful internal DSP.
  • Full-colour 4” LCD touch screen at the back, two round 8” displays on the front.
  • Balanced XLR line output (calibrated in dBU)
  • Phantom power XLR line/ Mic input.
  • Integrated class 2 laser pointer and laser distance meter (range 03-1.50m). SPL at the test position is calculated from the distance.
  • Rubber feet on bottom and back of device allow forward- facing and upward-facing Standard UNC camera thread mount provided for tripod use.
  • Powered and charged from 12V through an external AC adapter (included), or USB-C power adapter.
  • USB-C data cable for firmware updates, remote control and user uploads.
  • Wireless control via WiFi or bluetooth
  • Internal 4800 mAh NiMH battery pack for up to 3 hours of off-grid use.
 

Technical specifications of the BTB65 talkbox include:

  • Effective frequency range 80 – 16,000 Hz
  • Acoustic output level at 1 meter distance (vocal efffort) adjustable in 1 dB steps between 54 and 72 dB.
  • Line output adjustable in 1 dB steps between -30 and -12 dBU.
  • Noise, STIPA and Full STI signals conform to target spectra within 1 dB (measured at 1/3 octave resolution).
  • User calibration of the device supported with BAMT1 measurement microphone (not included).
