Wired IEM Pack / Headphone Amp
Wired IEM packs take the line level output from a mixing desk, and amplify it to a suitable strength to drive headphones or earbuds. They are a good low cost alternative to wireless in-ear systems, and are ideal for players that don't move around much, like drummers or keyboardists.
Each pack runs on a 9v battery (included with the hire) which means no trailing adaptors. They can accept a mono or stereo signal, with balanced XLR connectors and an auxiliary minijack input for backing music or click tracks.
Sound quality is excellent and the beltpack itself is lightweight and easy to handle.
