8X Series

Setting Standards.

Customer wishes and requirements are the only standard for Bittner. It is our pride to realise them in the most innovative way imaginable.

Confidence is good – two separate power supplies are better. And wear-free digital potentiometers, an integrated Noise Gate per channel, sequential remote power on, alive contacts for every channel pair, computer control – how much intelligent power fits into such a compact design?

8X – that’s multiple reliability. For the highest demands in sound and flexibility.

To handle a complete installation with only one dense power package – well, that’s what we call a standard.
