Description
The Adastra VH175.0 is a handheld VHF microphone transmitter built as an optional addition or replacement for Adastra portable PA systems. It works with the DT50, QR12PA and QR15PA units, sending audio wirelessly at 175.0MHz over a range of up to 50 metres. If you already run one of these systems and need a spare or an extra handheld mic (microphone), this is a straightforward match.
Inside the housing sits a unidirectional dynamic capsule, which picks up sound from the front and rejects noise from the sides and rear. That helps keep speech clear and cuts down on unwanted background pickup, so it suits presentations, announcements and general voice work. The mic measures 270mm long with a 45mm diameter barrel and weighs 190g, giving it a solid feel in the hand without being heavy over a longer session.
Power comes from a single 9Vdc PP3 battery, which is supplied in the box, so you can get started without a separate trip to the shop. The VH175.0 is one of a range of frequency-matched transmitters from Adastra, sitting alongside the 952.413 (174.1MHz) for the DT50, the 952.417 (174.8MHz) for the EZPA Lite and the 952.411UK for the H25 PA unit. Check that the frequency of your handheld matches the receiver in your PA system before you buy, as each transmitter is tied to a set channel.
