The Show AH150.8 installation power amplifier delivers 150 W per channel on 70 V or 100 V lines when all eight channels are driven simultaneously. Its Class-D amplification uses switching power circuits.

Input sensitivity is 0.9–1.1 V, and input impedance is 20 kΩ for a balanced connection or 10 kΩ for an unbalanced connection. It features protection against short circuits, open circuits, overheating, ultrasonic signals and RF interference, as well as protection during power-on and power-off, and muting. The inputs and outputs are Euroblock type.
