Description

The Adastra H25B is a fully integrated PA unit built into an ergonomic ABS handheld housing. It runs from either the mains or an internal rechargeable battery, giving you up to 25W of output whether you have a socket nearby or not. That makes it a practical choice for demonstrations, speech reinforcement in classrooms and general mobile public address where you need to be heard clearly without a lot of setup.

For hands-free speaking, the H25B comes with a VHF wireless neckband microphone system. The beltpack transmitter uses a quartz crystal locked carrier at 174.1MHz for stable tuning, and it works at distances up to 35m from the main unit. The neckband style keeps your hands free while you move around, which suits teaching, guided tours and product demos. The beltpack runs on a single 9Vdc PP3 battery and weighs just 76g without it.

Alongside live speech, the unit handles background music through three sources. A built-in Bluetooth receiver lets you stream from a phone or tablet, an internal USB media player takes a USB stick (US: flash drive), and there's an FM radio tuner too. The main unit measures 155 x 183 x 285mm and weighs 2.74kg, with a frequency response of 100Hz to 12kHz and a signal-to-noise ratio above 75dB. Battery life reaches up to 7 hours for voice use and around 2 hours when running a signal source.
