TOA / A-3606D PA amplifier 60W

The TOA A-3606D is a 60W PA amplifier compatible with high/low impedance, featuring four microphone inputs, three auxiliary inputs, and a built-in two-zone selector. In addition to individual volume control for each input, it includes priority broadcasting, chime, signal processing, and status check functions. It also employs a PFC (Power Flow Correction) circuit. It is ideal for paging and background music broadcasting in schools, offices, supermarkets, and other similar settings.
