Description
This kit pairs the Vision AV-1900 mixer amplifier with a pair of Vision SP-1800 passive wall loudspeakers, giving a complete sound system for meeting rooms, classrooms, lecture theatres and small halls.
The AV-1900 is a Class-D amplifier delivering 2 x 50W RMS into 8 ohms. It has four inputs that each accept a balanced microphone or a line-level source, with rear-panel gain trim and switchable 48V phantom power on every mic input. Input 3 can be used as a Bluetooth 5.0 receiver, input 4 is duplicated on the front panel, and RS-232 allows control from a room control system. Rack ears and two 5m speaker cables are included.
The SP-1800 speakers are 3-way designs with a 5.25in woofer, 1in mid-range and 0.5in tweeter, a bass reflex port and a metal grille. They are rated at 50W RMS, 8 ohms, and come in white ABS with wall brackets that tilt 30 degrees up or down.
