Quadruple 1U 19″ rack-mountable amplifier with 4 input channels and 4 independent speaker outputs. Each output can deliver up to 60W into low impedance speakers (4 or 8 ohms) or 100V by connecting either the top or bottom screw terminals on the back An internal media player can play audio files from a USB pen drive, tune into FM radio stations or connect via Bluetooth® to a smartphone for wireless playback of stored audio tracks. A paging mic input has a Vox toggle function for bypassing other channels. 2 additional balanced inputs can be selected to accept mic or line input with switchable phantom power. Channels 1 to 3 also have Bass and Treble controls for tone adjustment. A separate line input has an RCA connection or screw terminal and, if required, can be changed to accommodate the internal media player. Each of the four inputs can be selected to any or all four output zones, each with a separate output level control and line level output for expansion to further amplification ifiers or powered speakers. An optional CS4 call station can be added if a specific paging area is required, providing a fully independent and flexible zone system for background music, recorded information and announcements.
