SHOW AH150.2 2-Channel Power Amplifier

SHOW AH150.2, a professional 2-channel Class D amplifier delivering 2 x 135W at 100V and 70V, with up to 150W output when operating a single channel and a frequency response of 100Hz–15kHz.

Each channel features an independent level control on the front panel, along with LED indicators for signal, clip and protection, while a separate power indicator provides clear operating status. Inputs and outputs are provided via Euroblock connectors, making the amplifier easy to integrate into permanent professional audio installations.

The amplification system is based on a switching power supply and Class D circuitry, offering a compact 1U design for installation in a standard 19” rack. The AH150.2 also features protection against short circuit, open circuit, overheating, ultrasonic signals and RF interference.
