Sennheiser SK 6000 BK A5-A8 Digital Wireless Bodypack Transmitter
The Sennheiser SK 6000 BK A5-A8 (Article Number: 506319) is a professional, high-end digital wireless pocket transmitter from Sennheiser’s flagship Digital 6000 series. Designed for broad scale theater productions, top-tier live music tours, major broadcast operations, and complex corporate settings, this high-performance bodypack provides maximum spectral efficiency and absolute signal reliability under demanding conditions.
This specific variant operates in the A5-A8 frequency band (550.000 MHz to 638.000 MHz). With an 88 MHz switching bandwidth, it features advanced, intermodulation-free technology that allows users to operate across a dense RF environment without experiencing interference dropouts.
Key Performance and Technical Attributes
-
Intermodulation-Free Equidistant Grid Architecture: Inheriting technology from the legendary Digital 9000 series, the SK 6000 handles signals linearly without generating intermodulation distortion. This permits an equidistant channel frequency grid, allowing operators to stack channels evenly across tight frequency windows without calculating complex intermodulation math.
-
Proprietary Audio Codec (SeDAC/SePAC): Employs Sennheiser’s high-tier Performance Audio Codec to deliver clear, artifact-free digital audio resolution. It replicates studio-like audio purity across a broad 30 Hz to 20,000 Hz frequency response while maintaining a wide dynamic range (greater than 111 dBA).
-
High-Density (LD) Transmission Mode: When dealing with ultra-congested spectral bandwidth, switching into Link Density mode allows you to host up to 5 individual audio links per 1 MHz of bandwidth, maximizing spectrum layout without sacrificing signal tracking stability.
-
Robust Magnesium Alloy Housing: Built using a specialized matte-black magnesium shell that delivers live-compatible ruggedness and moisture protection while remaining light on the actor’s or musician's belt line.
-
Secure Signal Encryption: Outfitted with integrated hardware-based AES 256 encryption and proprietary Digital 9000 encoding protocols, making it a reliable solution for private corporate events, state installations, and high-security live broadcasts.

System Deployment and Hardware Interfacing Advice
Locking the 3-Pin LEMO Audio Interface: The SK 6000 uses a premium, moisture-resistant 3-pin connector. It pairs seamlessly with high-tier lavalier microphones (such as the MKE 1, MKE 2, MKE 40) and specialized headworn boom mics (like the SL Headmic 1 or HSP series). Ensure that you push the micro-connector into the socket until the outer collar locks with a distinct physical click. Always pull directly on the knurled metal collar to disconnect—never yank on the flexible microphone wire.
Battery Architecture Warning: To maintain low operational costs and stable weight balance, the SK 6000 does not bundle power elements out of the box. You must provision either a BA 61 rechargeable lithium-ion battery pack (delivering roughly 6.5 hours of continuous transmission tracking) or a B 61 dry battery case configured to host three standard AA batteries. Ensure that you monitor real-time battery telemetry via the backlit LCD screen or remotely inside your EM 6000 receiver channel layout.

First ball was great!
Color: Black Green, Size: 8 Inch
This ball was great! My dog loves it. I ordered another smaller one. It had no pump and the inside was separated from the outside piece so it couldn’t be pumped up.

Fun and durable
Color: Flag, Size: 6 Inch, Color: Flag, Size: 6 Inch
I have a 5 month old teething Whippet puppy and this toy is a favorite. She loves carrying it around by the straps, playing tug, and trying to chew it. I think it’s pretty tough and durable for someone her size. I could see how a shepherd might destroy it quickly, though.
I was surprised to find you have to inflate it, but the pump and needles are included and it hasn’t lost any air over several days of rough play. (I kick it and toss it to her. We tug with the straps. She carries it everywhere.) The material feels like a heavy duty soccer ball, just smaller. It’s the perfect size for her.
I’d definitely buy it again.

It's a (smaller) soccer ball with nylon straps. Will no last long for aggressive chewers.
Color: Black Green, Size: 8 Inch
As the item title states, it's a soccer ball with straps. It feels like a soccer ball, but smaller and doesn't make any noises. The 8 inch size just right for my 50 lb dog. He can't get his mouth around the ball, but can bite down on the straps as we kick it around. He also plays and tosses it around by himself. It's also easy to clean.
It's a good item, but suffers from two issues.
01) The nylon straps are tough, but not as durable as I though. My dog is aggressive chewer and has managed to chew them up a bit.
02) There is a nylon strap that is longer than all the others, so he tends to focus on that one. After about 15 days of playing with hit, he's managed to chew that strap up to the point that it's almost falling off. It would be nice if all the straps were the same, larger, size.

Highly recommend
Color: Black Green, Size: 8 Inch
I was skeptical that it would hold up to our aggressive chewer puppy (staffyX) - especially during teething. But it has survived past teething into adult chompers and is still fantastic! Its his favorite outside toy, especially the tags make it fun (and those have been holding up well too). If/when it fails, I'll buy another one.

great design, poor overall quality
Color: Black Green, Size: 8 Inch
My dog loves these balls. The "tags" are a great design. The problem I have is the quality as they aren't tough enough. He goes through them pretty quickly tearing off the tags and puncturing the ball. He doesn't get that these actually cost money!
Each one also comes with a small pump, which I guess is great for a one time buy?, but man, if you don't own a pump just buy one and keep one. I have no use for several of these cheap pumps. How about offering the pump as an add-on for a dollar or two?
