Product Description
The original Whirlwind Qbox was developed in response to requests for a simple test device that could generate or listen to signals, from mic level to amplifier drive level, at any point in a sound system. The Qbox does that with a built in condenser microphone or test tone generator. It also listens with its built-in speaker or headphone jack. There are lights to verify the presence of phantom or intercom power and it can be used as an intercom, monitor speaker, setup generator, etc. This unit supports the Divide and Conquer principle of troubleshooting. By substituting a Qbox at a problem point in a system, the user can easily verify signal presence or generate signal to determine if the problem lies farther down the line. The AESQbox recognizes digital sample rates from 32 kHz to 192 kHz. A set of INPUT SAMPLE RATE indicators shows the following sample frequencies in kHz 32, 44.1, 48, 88.2, 96, 176.4, and 192. A FAULT LED indicates problems with the data stream or hardware. The digital audio is converted to analog and may be monitored via a high quality unbalanced, 18 TRS stereo lineheadphone output or with the built in speaker. The channel monitored by the speaker is selectable with a switch. One of the requirements of this design is to produce high quality audio. The headphonespeaker amp circuit has superb THD and noise specs and the line output will have near pro-quality sound. The idea is that this unit can also double as a quality, portable AES-to-Line or Line-to-AES converter.
