H4SOUND H4PA 2 150
The H4PA-2-150 is a two channel Class-D power amplifier with an output
power of 150W per channel. Both channels can be configured either as a 100V - high
impedance output, or a low impedance 4Ω output (T version) or are exclusively used with 4Ω
output (standard version). With both analog XLR and digital USB-B inputs for each channel, it
provides a flexible platform for various applications, such as bars, restaurants, offices, etc. The
built-in DSP platform provides an excellent basis for further upgrades regarding user
experience, audio signal processing and ease of integration. The 1HE low profile of the
amplifier makes it perfect for tight and volume restricted spaces, while natural convection
cooling of the amplifier ensures quiet operation in every application, without overheating
concerns. The amplifier boasts a multitude of protective features, ensuring the amplifier stays
protected even in the case of unwanted operation.
