About: Behringer SD8 8x8 I/O Stage Box

Digital mixing has revolutionized virtually everything in the live- entertainment production workflow. Now we’ve come up with the perfect solution for connecting the onstage talent with your Front of House (FOH) console, and the rest of the world – the ultra-cool and ultra-affordable SD8 Stage Box! The SD8 provides 8 MIDAS-designed remote-controllable mic preamps, 8 balanced analog XLR returns at the stage end, plus an integrated 2-port ULTRANET distribution hub for direct connection to our P16-M personal monitor mixers – without any additional hardware required. Plus the SD8 is extremely compact and comes with rugged protective bumpers, so you can toss them directly on stage wherever you need them. The best part – all it takes is a single Cat 5e cable per stage box. And If you need more inputs, or just want to keep your cable runs short and tidy, putting an SD8 at stage front and another behind the drum riser gives you an additional 8 inputs for drum and guitar/ bass amp mic’ing.

When used as part of a complete X32 system, as many as three SD8 Stage Boxes can be cascaded via the built-in AES50 ports to provide up to 24 bidirectional inputs and 24 balanced XLR outputs. An onboard ULTRANET distribution hub provides power and 16 channels of audio to 2 BEHRINGER POWERPLAY P16-M personal monitor mixers per SD8, all via inexpensive Cat 5e cabling – and without any additional hardware. Two of the programmable inputs are also compatible with Hi-Z sources, so you can connect keyboards, acoustic and bass guitars, etc., with no DI box required. The SD8 also features a USB port for fast and easy system updates via your PC.

MIDAS - The Legend in Sound Quality

Ever since its formation in the 1970s, MIDAS has had a long history of innovation and leadership in the world of audio mixing consoles. Employed by the most famous touring acts and installations world-wide, legendary MIDAS consoles such as the XL4 and Heritage H3000 quickly became industry standards.

MIDAS has earned their impeccable reputation due to their no-compromise approach for audio and build quality and in particular for their Award-winning Mic Preamps which are considered by industry experts as the industry’s best sounding designs. Building on this legacy, the XL8 and PRO Series of Live Mixing Systems continue this great heritage of Award-winning audio quality.

BEHRINGER is proud to incorporate MIDAS designed mic preamps for the ultimate in high-quality audio reproduction in both live and studio environments. Find out more about MIDAS’ amazing legacy by visiting their extensive website.

Remotely Controllable Preamps Make Setup a Breeze

The SD8 Stage Box is a studio/live sound engineer’s dream come true. Setup is extremely easy, with virtually all parameter control taking place at the console – including the award-winning MIDAS-designed mic preamps, +48 V phantom power, destination routing, etc. Just put the SD8 where you want it, run a few Cat 5e, mic and instrument cables – and head for the console. The SD8 makes setting the stage up virtually foolproof!

8 Servo-Balanced XLR Outputs

The SD8 features 8 XLR balanced outputs, allowing you to connect to your amp racks, active loudspeakers and monitors. Thanks to its reference-class Cirrus Logic* 24-bit converters, SD8’s digital operation eliminates even the slightest possibility of Radio Frequency Interference (RFI) and crosstalk. You get ultra-pristine audio performance, no matter your application – something unheard of in this class!

ULTRANET – Seamless Integration

The world-renowned engineers at MIDAS, KLARK TEKNIK, TURBOSOUND and BEHRINGER have all come together to create something truly innovative that will change your live and studio workflow forever – welcome to ULTRANET. This revolutionary technology seamlessly transmits up to 16 independent channels of 24-bit digital audio and control data via a single Cat 5e cable between compatible digital devices – including mixers, I/O stage boxes, powered loudspeakers and personal monitoring systems. Advantages realized through ULTRANET digital networking, versus traditional analog methods, include: all audio signals are impervious to Radio Frequency Interference (RFI); signal crosstalk is eliminated, and ease of use translates directly into a significant amount of time saved during show setup or installation.

ULTRANET effectuates a powerful digital eco-system that gives you unparalleled control over every element of your audio production environment from one convenient location.
