Grenada Audio analyzer A8

A8 is a true multi-channel audio analyzer, which supports analog 8-channel simultaneous input/output and digital interface (BT, I2S, HDMI, PDM, etc.) expansion. It is an ideal test equipment for consumer equipment such as home theater receiver/professional Mixing console, etc.

Product Description

A true multi-channel analyzer that is not only a quick test, but also a simultaneous evaluation of multi-channel audio performance. Today's mainstream A/V receivers, media players and multi-channel audio products such as automotive audio and video testing still use the traditional two-channel audio analyzer combined with audio switch to achieve, its slow test speed, multi-channel complex relationship can not be evaluated and other problems have been plaguing product developers. The A8 audio analyzer solves the shortcomings of traditional testing methods, not only providing ultra-fast test speeds, but also testing complex relationships between multiple channels.

Key features:

  • Analog 8-channel input and output
  • SPDIF/TOSLINK/AES/EBU digital interface is supported as standard
  • Support BT/HDMI/I2S/PDM and other digital interface expansion
  • Supports simultaneous testing of multi-channel audio, including:
  • One-to-many/many-to-one channel resolution vs. phase difference
  • Maximum power over time for all channels
  • In combination with the switch box, up to 192 test channels can be realized
  • Complete and powerful electroacoustic testing functions
  • Code-free automation and comprehensive API interface
