Tester - all in one audio line tester/generator/intercom

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).
