Acclaimed Sound Devices Astral® series of wireless transmitters includes new Test and Measurement (T&M) mode

Last updated

Up until now, users wishing to measure the frequency and phase response of their loudspeaker systems have had to rely on either cumbersome hardwired microphones, or utilize subpar wireless systems, with undesirable phase and frequency response. Now, with Astral ARX16/ ARX8 v1.63 and Astral Mini/Astral TX v7.64, users can utilize an Astral ARX16 or Astral ARX8 receiver along with Astral TX or Astral Mini transmitters to very accurately measure the phase and frequency response of loudspeaker arrays, with near cable-like response.  

This response, combined with the following features of Astral TX transmitters and Astral ARX16 or Astral ARX8 receivers make the Astral system ideal for demanding situations utilizing high-quality balanced measurement microphones:  

  • Built-in fully-balanced high-performance microphone preamp 
  • Built-in 48V phantom power 
  • GainForward™ architecture: no gain adjustment needed at the transmitter 
  • Full remote-control (including power on/off) of transmitter from the receiver 
  • Global operation, tuning from 169 MHz – 1525 MHz on both the transmitter and the receiver (470 MHz – 1525 MHz for Astral Mini) 
  • Full AutoAssign one-button frequency assignment for all transmitters 
  • Easy-to-use GUI for simple operation
