Australian Monitor HS250-V2: 250W Class D Mixer Amplifier

Australian Monitor HS250-V2: 250W Class D Mixer Amplifier The Australian Monitor HS250-V2 is a professional-grade 250W mixer amplifier designed for high-density installations in corporate, educational, and hospitality environments. This 1RU unit is part of the next generation of Class D amplifiers, offering a significant reduction in weight and heat generation while maintaining powerful audio performance. The V2 update introduces an enhanced Bluetooth 5.1 module, which allows for advanced customization of the broadcast name and security PINs via a PC application. Versatile Input and Mixing Capabilities The HS250-V2 features a nine-channel mixer consisting of seven external and two internal audio inputs. The rear panel provides six universal mic/line inputs with options for XLR, Euroblock, and RCA connectors, while a 3.5mm jack is available on the front panel for quick auxiliary connections. The unit includes a built-in MP3/WAV player that supports playback from an onboard SD card slot, allowing for automated music or custom messaging. For system security, the amplifier includes a magnetic concealment cover that hides the gain and tone controls, preventing unauthorized adjustments after the system has been commissioned. The priority muting system is highly flexible, allowing channels 1 through 3 to duck background music or tones based on four different priority modes. Integrated Tones and Modern Connectivity The embedded tone generator comes pre-loaded with five standard tones, including bell, alert, evac, and chime. Users can also upload up to 11 custom user tones via the SD card slot to suit specific facility requirements. The programmable Bluetooth 5.1 module is a standout feature for commercial spaces, enabling staff to stream music from mobile devices with a secure, named connection that prevents accidental pairing from neighboring rooms. The amplifier supports 4-ohm, 70V, and 100V outputs, making it suitable for a wide variety of speaker configurations. Its efficient Class D design and universal power supply allow it to operate reliably under diverse power conditions and in tight rack spaces where airflow might be limited.
