QT-256 World's Smallest Broadcast Quality Wireless Microphone Transmitter
Progressively since it’s inception, through the earliest prototypes and several revisions, we have seen the Q5X series of micro-transmitters evolve toward this latest generation offering its best performance specifications yet. To date, the QT-256 has risen to advanced levels meeting improved transmit/reception distances, increased fidelity, and exceptional overall reliability including the length of transmitting the rechargeable battery life promises. Enabling installation and applications that never before have been possible in athlete user sized RF transmitters under game conditions and league application guidelines, we continue to make great use and credit the designers and the unique packaging of the QT-256.Its ease of use and flexibility in our varying arena of sports application uses enable us to move ahead as leaders in television sports technology users.
I've used two Quantum QT256 wireless systems on the second season of Lifetime's TV series Wild Card. They were invaluable on our lead actors due to wardrobe and personal preferences. These units are the size of a Zippo lighter and can hide under the skimpiest of costume. Their sound is open and natural; very "boom-like" Excellent compliment to the rest of my sound package.
Gear worked great, sounded awesome. I foresee player mics in all our futures....sigh. My only issue with the Quantum's is the rechargeable function. I feel safer with batteries I have control over. Although they were turned on at 9:30am and lasted until I turned them off at 3pm
The QT 256 worked wonderfully. They were unobtrusive, easy to use and sounded great.
Thanks for all your help.
I had the opportunity to use Quantum5X RF mikes on a documentary I was working on for the National Hockey League. The Q5X transmitters are smaller and lighter than any other transmitter I have ever used and they are already being used by NHL refs and NBA players for their live broadcasts. So when it came time to mike each of the linesmen and referees for our documentary, they were happy to wear the Q5X transmitter. They knew its small size and light weight would not affect their ability to do their job on the ice.
The Q5X system seems to be well-suited for professional sports. I had no problem with the rechargeable battery lasting the entire game and the range was impressive even though I was working off battery power without the benefit of an antenna booster. Additionally, its small size and its resistance to moisture make it an interesting alternative where other RF transmitters simply cannot be worn.
All in all, the Quantum5X is an impressive device with enormous potential.

State of the Art
The 256 transmission frequencies of the QT-256® are selectable from 600-698 MHz. It has proprietary DCS-QT compounding, pre-emphasis and provides high quality broadcast audio with RF output power ranging from 30-250mW. The included ¼″ whip antenna is fastened with a Small SSMA bulkhead connector. The audio connector is a high-end 4-pin LEMO which cleverly doubles as a battery charging port. LEMO lavaliers by Countryman, DPA or Sanken are available separately.
Receivers
The QT-256® is designed to work flawlessly with the Q5X series of receivers: QR-1000, QR-2000 and QR-500. It could also be modified to be compatible with some other wireless mobile and rack mount receivers.
