SHOW AH500.2, 2-Channel Power Amplifier

SHOW AH500.2, a professional 2-channel Class D amplifier delivering 2 x 400W at both 100V and 70V, with up to 480W output at 100V or 500W at 70V when operating a single channel, and a frequency response of 100Hz–15kHz.

Each channel features an independent level control and LED indicators for signal, clip and protection, while input and output connections are provided via Euroblock terminals. The switching power supply and Class D design allow the high-power output to be integrated into a compact 1U chassis, suitable for installation in a standard 19” rack.

To protect both the amplifier and the connected system, the AH500.2 includes protection circuits against short circuit, open circuit, overheating, ultrasonic signals and RF interference.
