I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world. Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!
AWPB-1W-VHF
Frequency Range: 175-240Mhz
£695.00 ex vat 
£834.00 inc vat
The UHF AWPB-1W amplifier delivers up to 1W output power with 12 dB small-signal gain, excellent gain flatness, wide dynamic range, and a low Noise Figure. It is designed to boost low-power radio microphone transmitters to a full 1W for applications such as sports audio links, car-to-car recording, IEM TX range extension, and similar long-range needs.
A custom-tuned, highly selective band-pass filter in the output stage sets the operating frequency range and effectively suppresses 2nd and 3rd harmonics.
Gain can be adjusted in 0.5 dB steps via the intuitive OLED interface. A real-time DC voltmeter monitors input voltage continuously, and the Lock Menu prevents unintended changes to user settings.The booster is compatible with any UHF wireless transmitter operating within the same tuning range, including Digital, Hybrid FM and Analog FM systems. Its wide input dynamic range accepts transmitter power levels from 0 dBm (1 mW) up to +18 dBm (63 mW).The AWPB-1W features a compact, custom-designed enclosure with an integrated heat sink and advanced PCB thermal design to minimize heat build-up. The CNC-machined aluminium housing is black-anodized and laser-marked, providing durability and reliable performance in demanding environments.
