The Hill Audio IMM-2320V2B Media Preamp/Mixer combines a 3-input stereo mixer with 2 microphone inputs and an internal media player. The auto-talkover feature of the microphone section allows automatic attenuation of the music signal by an adjustable amount when speaking into a microphone. This makes the unit a perfect companion for fitness instructors or presenters who have no hand free to lower the program level while speaking. The internal media player sports an IR remote for added comfort; it also features a jingle player, which runs both in a one-shot and a scheduled mode. Two master outputs with fire evacuation facilities like external mute and emergency signal priority functions complete the feature set of this comprehensive unit. The IMM-2320V2B is the ideal core unit for fitness sound systems, hospitality sound systems and mobile sound systems deployed for educational or promotional applications and also has an additional built-in Bluetooth module.
