Proprietary HeatBlock material products block heat of wireless mic transmitters

K-Tek introduces Stingray HeatBlock transmitter pouches, and HeatBlock Pieces, a new way to protect the talent from heat produced by wireless microphone transmitters worn on set.

Wireless microphone manufacturers have made great strides in producing smaller and more powerful transmitters for their devices that are often body worn. However, this technology can generate uncomfortable heat when positioned next to the body. To solve this issue, K-Tek designed HeatBlock transmitter pouches and handy swatches of the same fabric, HeatBlock Pieces.

After extensive research and field-testing, K-Tek devised the new Stingray HeatBlock line. The secret is a patented, heat resistant material that is both soft to the touch, and flexible enough to comfortably be worn against the body. The proprietary three layer material is specifically engineered to withstand a continual temperature of up to 240°C (464F°), well above the range at which the electronics are specified.

The results are positive, earning praise from professionals. “Since I’ve been using HeatBlock pouches I no longer hear complaints from the actors, about the transmitters being too hot,” explains award-winning Production Sound Mixer, Steven Tibbo C.A.S., who is known for his work on features, documentaries and TV series such as Modern Family.

This advanced material is soft and comfortable to wear against skin yet offers superb insulating characteristics to eliminate the discomfort associated with wearing wireless transmitters. A series of three pouches snugly encase most popular transmitter brands. Fabricated without protrusions or sharp corners, they can be used with or without transmitter clips. What’s more, every pouch and HeatBlock Piece is meticulously hand-sewn at the K-Tek headquarters in California, USA.

Available in three sizes, there’s a Stingray HeatBlock Pouch to fit most popular microphone transmitters, including the Zax ZMT and the Lectro SSM, SMV and SMQV models. Heatblock Pieces are sized to correspond with the Pouches and come in a set of six with two of each size.
