Adastra 5-channel 240watt 100V Wifi Amplifier

This Adastra 5-channel 19" rack-mountable mixer-amplifier, designed for commercial sound installations to power 100V line speakers or standard low impedance speakers. Input options include XLR (with switchable phantom power), mic/line jack, and RCA line. A switchable ‘voiceover’ feature automatically lowers the background music volume when a signal is detected via mic input 1, and rear panel 24V contacts can mute all except mic input 1 when triggered. A built-in audio player section can play mp3 files from a USB or stream audio wirelessly from Bluetooth®. A main feature of the RM-WIFI models is the ability to connect to a wired or wireless network for streaming audio from internet radio, playback services or even from a local NAS drive. Setup and control for this function is entirely via the WiiM Home­­ smart phone app with a choice of streaming services embedded. Outputs on screw terminal are via 4 switchable zones with a separate "always on" output for priority alert speakers.
