Russound X225 Two-Channel Amplifier (150/225W)

Two-Channel Amplifier (150/225W)
Discontinued - No Direct Replacement

The Russound X225 is a 2-channel dual source power amplifier with auto-source switching. It features Primary and Secondary audio line inputs with a loop out to another zone, receiver, or device from the secondary source. A speaker-level input can be connected and assigned as either the primary or secondary source. This amplifier can be used for power upgrades in zones for large speaker selector or volume control systems.

The X225 is rated at 225 watts per channel into 4 ohms, and 150 watts into 8 ohms. Each amplifier output channel incorporates robust protection circuitry for reliability and safety under extreme circumstances. With the Stereo/Bridge Mono switch in the Bridge Mono position, both amplifier channels are combined for a higher powered mono output. In Bridge mode the X225 is rated at 470 watts of power into a single 8 ohm load. The 12V Trigger In/Out allows the amplifier to be activated by other devices or to activate other electronics via a 3.5 mm mini phone plug cable, with 100mA current capability.


  • Volume and balance allows for control at the component instead of volume control or keypad
  • A/B speaker switching easily toggles output between two sets of speakers or zones
  • Signal sensing inputs automatic turn on/off and switching to second source
  • Bridgeable - delivers higher output for use with a subwoofer or outdoor speakers
