USB

The dBbox2 has a mini USB connector for external power and to update the

firmware. Any USB outlet may be used to power the device, a computer or

even an iPhone mains adaptor using the correct mini USB lead.

Firmware updates will be available on our website, please see:

http://www.ctpsystems.co.uk/support.html

All new firmware may be downloaded from here along with instructions and

drivers.

Levels

All dB references in this manual relate to the following:

The dBbox2 '0dB' output level is 0dBu, that is it generates 0.775 volts into a 10k ohm

load, the most common input impedance these days. Into a 600 ohm load it will be

approximately 0.3dB lower. The dBbox2 balanced analogue output impedance is 75

ohms. Inevitably the dBbox2 will sometimes be plugged into a source with phantom

power or something unpleasant on the line and the unit must be able to protect

itself. This protection comes at a price which includes a slightly higher output

impedance in order to overcome these possibilities, hence the variation.

If you have any firmware problems with your dBbox2 or you spot any incorrect

details in our manual please let us know so we can correct. Thank you.
