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.
- Up to 8x 400 W @ 4 Ohm in only 2 RU
- 4 separate stereo amplifiers
- Ideal for fixed installations: Controls from the back panel only
- High Tech SMT Design
- Protection Circuits: DC, LF, HF, Thermal, Short Circuit, Current Limiter, 3 ms Muting Delay
- All inputs and outputs pluggable with PHOENIX connectors
- 2 High-End toroidal transformers
- 2 seperate power supplies
- LED indicators for SIGNAL, CLIP, PROTECT, POWER
- Temperature controlled, variable speed low noise fans
- Softstart
- Sequential Remote Power On
- 4 Alive Contacts
- Digital wear-free Volume Controls (can be operated manually)
- SXL Dataport
- Noise Gate (switchable)
- 3 Years Warranty
8XT – The Ideal Pair!
Simply connect an 8X amplifier to an 8XT multi-channel output transformer and you’ll be ready to meet our European norms and standards.
