The CRS201-H infrared wireless microphone system is ideal for classrooms, boardrooms, computer training rooms and hotel meeting rooms. The slim, fully lockable, wall-mounted infrared receiver/amplifier/mixer accepts three different line level inputs. Because the CRS201-P is wall-mounted, there are no freestanding or rack-mounted components to take up closet space or be knocked off a shelf and no unsightly tangle of wires.
