Behringer's ADA8000, or the Ultragain Pro-8 Digital to give it its full name, is a conceptually simple product that should interest anyone who uses ADAT connectivity within their system. Its mains-powered 1U rack format houses eight mic/line preamps with phantom power, and these feed an oversampling delta-sigma A-D converter, which in turn sends eight channels of 24-bit digitised signal out of the back panel via an ADAT lightpipe connector. These preamps use the same Invisible mic preamp circuitry found in the newer Behringer mixers, and my experience of them so far has been favourable. Phantom power is switchable globally, so the preamps may be used with active DI boxes or capacitor mics that need a 48V power source, and each of the channels has a rotary gain control (with up to 60dB of gain) plus a pair of LEDs to show signal present and clipping. The line input is on a balanced TRS jack and mic/line input selection is accomplished simply by deciding which socket to plug in to.

The unit also features an ADAT lightpipe input that feeds a D-A converter, where the analogue signals emerge as electronically balanced XLR outputs on the rear panel. There's a word-clock BNC input to allow control from a master clock source, and a slide switch on the rear panel sets the unit to master or slave mode (with a choice of ADAT or word-clock sync) at a choice of 44.1kHz or 48kHz internal clock rates. I would have preferred this switch on the front panel, where it would be more accessible, and I'd have liked more digital status displays, though I don't know where they could have put them.
