The Whirlwind Qbox-AES is a portable, multipurpose testing device that allows you to troubleshoot digital and analog audio signals. The unit has two sections; a Send section and a Receive/Monitor section. The Test Mode switch selects between analog or digital testing modes.

In the AES test mode, LEDs light up to indicate the sampling rate of the incoming digital audio from the BNC or XLR inputs. The digital signal is decoded and output through the built-in speaker or the 3.5mm jack for connection to other gear. The digital Send section converts a choice of analog input signals into AES-3 and S/PDIF digital formats and delivers them to the output connectors through the Send Level and Sample Rate controls. The In-line Monitor function lets you insert the Qbox-AES into an AES stream for real-time monitoring.

In analog test mode, XLR connectors are used to send and receive analog audio signals. Microphone, oscillator, and Aux signals are routed to the male XLR through the Send Level control. The female XLR receives the analog input and delivers it to the speaker with volume control. A three position switch allows the selection of a balanced input or unbalanced pin 2 or pin 3 to be monitored separately. LEDs indicate the presence of phantom power at the male XLR.

The Qbox-AES is powered by the included 6 VDC power supply or can operate for up to six hours on four AA batteries (1 hour if speaker is at full volume).

  • Tests both AES digital and analog signals
  • Transmit and Receive sections can be used independently or can be set to In Line Monitor where the Qbox-AES is acting like a repeater
  • Send/Receive Test Mode allows the operator to pass the digital signal through a cable and back into the Qbox-AES to verify cable integrity and bandwidth capability
  • Operates with battery or wall adapter power
Receive Section
  • Receives and identifies 44.1, 48, 88.2, 96, 176.4, and 192 kHz sample rates
  • Converts AES digital to analog and outputs the analog via built-in speaker or Line/Phones Monitor jack
  • Listen to individual A and B streams or summed together through the speaker
Send Section
  • Transmits at 48, 96, and 192 kHz sampling rates
  • Generate AES digital from analog Line In jack, built-in dual-tone generator, or built-in condenser microphone
  • LEDs indicate reference output level
