Monitor Audio Installation Amplifiers are designed to have the best possible performance with the least amount of rack space. Despite being entry-level, the IA60-4 has a full DSP matrix configuration and flexible power options. It can be set up to deliver four 60W channels, two 125W channels, or a single 250W channel with no performance loss when power sharing is used. All of this from a sturdy, space-saving 1U half-size design. The IA60-4 is perfect for small garden systems, height channels in home theater Atmos systems, and two zone stereo applications. Note: Installation kits for the rack and wall/desk are sold separately.
