The IA125-4 is a deceptively powerful amplifier that packs ultra-high-density amplification into its compact 1U half-rack form. It delivers 4-channels of 125 W or 2-channels of 250 W. Plus, it can be used in power sharing mode to support Monitor Audio’s THX Ultra certified, Cinergy 100 speakers within a home theatre system or medium sized garden. It’s the ideal amplifier for two zone stereo applications and height channels within home theatre systems.
Note: Rack and wall/desk installation kits sold separately.
