Designer 2 channel amplifier featuring 150 watts of class D power in a sleek 2U design.

An amplifier should be transparent, it should literally be just wire with gain. At Origin, we pride ourselves in offering no-compromise amplifiers to drive our loudspeakers. Whether you require a stereo or multi-channel version, our amplifiers feature high-efficiency, Class-D power that is built to last and will reproduce every nuance of every recording.


A2150 – Two Channel, Stereo Amplifier

  • At 150 watts of power to each channel and 300 watts to one channel in bridged mode and the ability to consistently drive a 4-ohm load, this is a workhorse that can be used as a building block in any system.
  • Its automation and protection circuits serve to make it a perfect choice for home theater or multi-room/multi-zone applications.

Class-D Power

  • This switching type amplifier class has incredible efficiency, above 90%, as higher power is demanded.
  • This means substantially less heat is produced even though the amplifier is able to produce substantial power.
  • This also means a reduction in size as smaller heat sinks are required and the electronic circuitry can be more compact and reside in a smaller chassis.

Bridgeable Circuit

  • Bridging two channels into one drives almost triple the power into a single output. This feature creates greater flexibility in system design when additional power is a requirement.


  • Origin amplifiers can be placed in a rack or inside furniture and require no direct access to function.
  • They are turned on out of standby mode either by sensing the audio signal from a preamp or receiver or by a 12-volt signal from any number of components.
  • They also have a 12-volt output to trigger other components as necessary.


  • Built-in circuits that sense both thermal overload or a short-circuit in the speaker connections, will shut down the amplifier until the temperature level returns to normal operating levels or the short in the connections is corrected.
  • This protects the amplifier from permanent damage and avoids costly service visits and repairs.
