AESQbox



The Qbox Goes Digital

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.

A New "Generation"
But what do you do when transmit audio in an AES/EBU digital audio system and nothing comes out the other end? How can you verify that the sending unit is actually generating good data, that the data actually contains audio or that a receiving unit is working properly? In fact, some digital systems are so quiet that the total lack of hum and hiss can sometimes make it difficult to determine whether the system is even on at all. So, an AES/EBU digital system presents special troubleshooting challenges.

After gathering ideas from prospective users at trade shows and through email, Whirlwind engineers designed the AESQbox.

Following is a brief description of the AESQbox and it s functions. For a detailed description, you may download a detailed white paper here.

MODE Selections
Three operating modes are selectable with a MODE switch:
IN/OUT Normal Mode

PASS THRU The digital audio received on the input is passed through to the output at the same sample rate so that the audio content may be monitored – the AESQbox is acting like both a "wiretap" and a "repeater".

CABLE TEST The analog audio is delivered to the AES output where you may then test your digital cable by connecting from the output back to he AES input, which should allow the user to hear the audio. This could also be described as a "self test" mode for the unit as well as to verify the integrity of the cable.


Digital Input Section
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, 1/8" TRS stereo line/headphone output or with the built in speaker. The channel monitored by the speaker is selectable with a switch.

Digital Output Section
The SOURCE switch allows selection of MIC, TONE or AUX IN (a 1/8" TRS stereo unbalanced jack) as the analog audio source.
  • The built-in TONE generator provides 440 Hz for the left channel and 880 Hz for the right.

  • The built-in MIC is an electret condenser type and feeds both the left and right channels.

  • The AUX IN accepts line level stereo audio.
The analog signal is converted to AES/EBU digital and output via the male XLR jack and BNC.

Quality Audio
One of the requirements of this design is to produce high quality audio.  The headphone/speaker 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. 

Other Stuff
The AESQbox operates on 4 AA size batteries or with a 6V external power supply (included). A POWER indicator shows that power is on and allows the user to assess battery condition - when it gets dim, time to change the batteries.

Inputs and outputs are both DC and transformer isolated to prevent inadvertent damage to the unit.

Those are the basics but as the case with the original analog Qbox, we're sure that users will find other tips and tricks for the AESQbox that we haven't planned for.

NEW FEATURES!

Since its introduction in 1997 the Qbox has become one of Whirlwind's most successful "Black Boxes" ever. Now, we've added the features that have been most requested by Qbox users over the years:
  • A quieter headphone amplifier section for improved listening quality.

  • A handy MONITOR switch that allows the user to listen to a balanced signal or to separate unbalanced signals on pins 2 or 3 (referenced to pin 1), such as a two-channel intercom.

  • A switch that unconnects the two XLRs from each other so tone or internal mic can be sent out of one while you listen to what's coming back on the other. Or connect the XLRs together and "loop-through" or daisy-chain units.

  • An improved, test-tone oscillator circuit that more closely maintains the selected level into a wide range of load impedances..
The Qbox is the all-in-one audio line tester ideal for applications such as live sound, maintenance, installation work - anywhere audio runs down a cable. The Qbox includes a microphone, a speaker, a test tone generator, outputs for standard headphones, a 1/4" jack for line-in or a 2k Ohm (telephone) earpiece out, plus voltage presence LEDs for confirming phantom or intercom power. A handy clip attaches the Qbox to your belt or equipment rack.

For an instant hands-free intercom, simply plug in headphones and hook up one Qbox on each end of a line.

Use it to monitor a standard 3-wire intercom feed or talkback from the main audio console. The Qbox can quick-check dynamic mics without firing up the entire system. It provides a handy mic or line-level tone for activating a signal path or identifying a specific cable in a pile of cable ends. Powered by a single standard 9V alkaline battery and housed in rugged ABS, the Qbox is light yet able to withstand the wear and tear of fieldwork.

The SOURCE section of the Qbox lets you send a tone or the signal from the built-in condenser mic at mic or line levels.

The SPEAKER volume control lets you confirm incoming signals at mic or line level.

Cab Driver


The CAB DRIVER is a test device for checking the operation of the 
speaker components within enclosures. A pink noise signal source is 
sent through pushbutton selectors to an assortment of speaker connectors, 
including Speakon NL8 and NL4, 1/4" TS and banana jacks.

The pink noise level can be adjusted to appropriate levels for subwoofers, 
midrange cones and compression drivers and tweeters. There is also an XLR 
line output for feeding the pink noise to self-powered speaker units.
A DC OHMS TEST button applies 5 VDC to the output terminals selected with 
the pushbuttons for observing cone movement to identify speaker and cabling 
polarity errors. This also performs a DC Ohms test where three LEDs indicate 
approximate ranges of 4, 8, or 16 Ohms. This helps identify blown drivers in 
cabinets where the cones cannot be readily observed or in cabinets with multiple 
drivers in series parallel configurations.

The CAB DRIVER is powered by 4 AA batteries or can be powered by an external 
6 VDC power supply (not included). 

Dimensions 4.75" W x 4.5" D x 2.5" H.
