ADASTRA 100V Class D Multi-Zone Amplifier, 2x 120W, 1U Rack Mount

The ADASTRA 100V Class D Multi-Zone Amplifier is a versatile and powerful solution designed for demanding professional audio installations. This multi-channel slave amplifier provides independent outputs for both 100V line and 4-16 Ohm speakers, offering exceptional flexibility for zoning systems and public address applications. Its efficient Class D circuit design and toroidal transformer allow it to deliver robust 2x 120W RMS power while fitting into a compact 1U rack-mount housing.

Each amplifier channel features its own independent line input, which can be switched to a global auxiliary input. This provides the option to route the same audio source to multiple channels, ideal for background music or announcements across different zones. A dedicated paging microphone input with VOX override and switchable +20V phantom power ensures clear voice alerts and announcements. For critical safety applications, a 24V mute terminal can be connected to an alarm panel for emergency evacuation override, automatically muting all other audio.
