labBGN - Background noise hardware platform

Enquiry Item

labBGN is the key hardware component for operating HEAD acoustics background noise simulation systems. With the hardware platform and the corresponding simulation software (3PASS lab, 3PASS flex, 3PASS reverbHAE-BGNHAE-car), it is possible to record, equalize and realistically playback background noises as well as reverberation (impulse responses) – reproducible across different laboratories.

labBGN provides a maximum of ten channels: Thus, users are able to connect e.g. eight loudspeakers and one stereo subwoofer to the labBGN concurrently.

In conjunction with the simulation software (3PASS lab, 3PASS flex, 3PASS reverbHAE-BGNHAE-car), microphone arrays MSA I or MSA II (recording, equalization) as well as loudspeakers and power amplifiers, labBGN forms a powerful background noise simulation system.

Product Overview

Highlights

  • Record, equalize and playback true-to-reality background noise scenarios with labBGN
  • The hardware platform is used in conjunction with the background noise simulation software (3PASS lab, 3PASS flex, HAE-BGN, HAE-car)  as well as the software for simulation for reverberation (3PASS reverb)
  • In conjunction with the corresponding simulation software, labBGN supports fast and easy equalization of the whole simulation system

 

Product Features

  • labBGN provides one D-Sub 25-pin multi-functional socket for connecting eight loudspeakers (TASCAM compatible)
  • The hardware platform has two XLR output connectors for connecting a two-channel subwoofer or additional two loudspeakers
  • labBGN provides a 10-channel display of inputs and outputs as well as an ADAT input / output and HEADlink socket
  • Via the digital interface (AES/EBU) users are able to exchange audio data, e.g. with the hardware platform labCORE
  • labBGN enables monitoring of audio signals by headphones via 6.3 mm phone jack
  • Users are able to control all settings via software of 3PASS lab, 3PASS flex, 3PASS reverb HAE-BGN, or HAE-car
