A14 Dual Stereo Mixer-Amplifier 4 x 100W
Comprehensive 1U PA amplifier with 2 independent stereo zones and a global microphone input. Each zone has an independent audio player module which can select between USB / microSD mp3 player, FM tuner, Bluetooth receiver, 2 stereo line inputs (rear panel RCA) and another line input on the front panel (3.5mm). Playback can be controlled from the front panel or by the supplied I.R. remote control handsets. In addition, each player has an Aux 4 setting allowing it to connect to the other player module, meaning either one of these players can be used for both zones if needed. Mic inputs 1 and 2 are live to both output zones at all times. 2 pairs of speaker connections on the rear panel are connected using removable Euroblock screw terminals, which can drive up to 2 x 8 Ohm speakers on each of the 4 channels. The housing is 1U 19" rack-mountable and is supplied with front and rear brackets, which may be rotated for mounting flat against a wall or under a counter top. Overall, a complete solution for completely independent background music, audio visual and voice announcements in venues with 2 separate areas.
