The PA-20B amplifier is a very compact monaural amplifier specially designed for fixed or mobile applications. Its small size and light weight make it easy to integrate into a small space. The amplifier is class D, so it has high efficiency and low heating. Operation at 12 to 15V DC is perfect for portable use or for installations where direct AC power is not available. This amplifier is the ideal solution for information points, cash desks and vehicles using a roof speaker system. The amplifier is equipped with a Bluetooth module, which prevents physical galvanic connection to sound sources and thus eliminates the possibility of hum and noise. The USB 5V power plug can be used as a charger for external devices. There is a main switch on the front panel, and there are also 2 microphone inputs with 6.35 mm TRS jacks, rotary volume controls for both microphones and an AUX input, and easy EQ tone correction settings. There is one stereo AUX input on the rear panel with RCA and 3.5 mm jacks. The rear panel also has a DC connector ø5.5 / ø1.5mm for connecting the input supply voltage 12V to 15V / DC and terminals for connecting a load with an impedance of 4Ω. The amplifier includes a switched power supply 230V AC / 15V DC / 2A.
