Citronic FLITE-600 is a self-contained 2 x 300W PA amplifier with a fully featured mixer built into a heavy-duty moulded flight case with dual locking catches and a sturdy carrying handle. Opening the lid reveals a 4-channel mixer section with an additional stereo input and further individual volume controls for the internal USB audio player and Bluetooth receiver. Above the mixer section is a dual UHF microphone receiver module for the supplied pair of handheld wireless microphones, which are stored neatly in a separate compartment alongside the mixer section. Playback of audio files from a flash drive inserted into the USB port is controlled from the top panel and can even be used to record audio to the USB flash drive or connected to a PC/mac computer as a USB audio device for playback and recording. The DSP effects section has 99 programs with 2 editable parameters for each, ideal for instruments or vocals. Just add passive speaker cabinets to provide a complete setup for mobile entertainers, fitness instructors, schools and almost anyone needing a fully featured, professional PA system.
