Description
The Adastra VH174.8 is a handheld VHF microphone transmitter built as an optional addition or replacement for Adastra portable PA units. This particular version runs on 174.8MHz and is matched to the EZPA Lite system, so it slots straight into that setup without any fuss. If you already own an EZPA Lite and need a spare handheld, or you want a second mic for a bigger group, this is the part you are after.
The transmitter offers up to 50m of range, which covers most halls, classrooms and small event spaces comfortably. Inside sits a unidirectional dynamic capsule, so it picks up the voice in front of it while keeping unwanted sound from the sides and rear to a minimum. That helps cut down on feedback and background noise when you are working close to speakers. Power comes from a single 9V PP3 battery, which is supplied in the box, so there is nothing else to buy before you start.
At 270mm long and 45mm in diameter, the body has the familiar feel of a stage microphone (US: mic), and it weighs 190g, so it sits well in the hand over longer sessions. Do check the frequency before ordering, as Adastra makes matched versions for different units: 174.1MHz and 175.0MHz for the DT50, 174.8MHz here for the EZPA Lite, and a separate handheld for the H25 PA unit. Getting the right frequency means your transmitter and receiver talk to each other cleanly.
