Sennheiser ESFERA 5.1 Surround Sound System

Complete 5.1 surround microphone system including SPM 8000 X/Y microphone package and SPB 8000 processor

Product Description


How much more impressive and emotional are sports broadcasts that also manage to convey the spirit and atmosphere of the venue they take place at? An atmosphere, however, is something that surrounds you, while most of the time broadcasters have to resort to conventional stereo equipment. Mainly because of tight timing or owing to the fact that setting up surround sound gear is not supported by the infrastructure. These problems are now solved.

The solution is the Sennheiser ESFERA 5.1 Surround Sound System. It enables you for the first time to generate and broadcast 5.1 surround sound using two ordinary standard audio cables. All you need is the SPM 8000 microphone on location and the SBP 8000 basic unit at any given point within the production or post-production process before the audio signal is aired. The compact build of the microphone unit, which can be mounted on a camera, allows even sideline interviews or the application in tight spaces.


Surprisingly compact and easy to set up, the SPM 8000 actually consists of two RF condenser mics in XY-array. Fitted with technology of the legendary MKH series, it features a natural and detailed sound, and is also weatherproof and rugged, making it the perfect choice for outdoor use. Sports broadcasters will appreciate its extremely low inherent noise, which lets even the softest sound details be heard. The SPM 8000 comes with an all-in package including a basket windshield and a swing mount. Just as complete as the atmosphere you will be getting across to the audience.


The 19 in processing unit is fitted with the unique chip brains to convert a perfectly normal stereo audio signal supplied by two standard cables into a full-fledged 5.1 surround experience at a sampling rate of 96 kHz. For a broadcast- friendly signal the built-in compressor can be engaged. The SPB 8000 excels with a clear design and four directly selectable presets that can be modified via the Ethernet interface. The processor software allows you to individually define your surround soundscapes via the PC interface.


The software of the SPB 8000 allows you to individually define the parameters of four different surround sound settings which can be saved, and activated at the push of a preset button.


  • Can be used as a high-quality stereo microphone or, with the SPB 8000, as a compact 5.1 microphone
  • Very natural, detailed sound
  • Weather-proof and rugged
  • Exceptionally low inherent self-noise prevents masking of delicate sound structures

  • Input switchable between analog and digital AES3 signals
  • Switchable compressor
  • 4 programmable presets for storage of 5.1 surround parameters

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
