Using the Servo 550 in the bridged mono mode is a great way to power a separate subwoofer system as an enhancement to your overall sound. The 550 also shines in other live sound reinforcement uses, monitoring, and dedicated recording applications like powering near and midfield monitors and passive headphone distribution systems. Audio/Video installers appreciate the 550's versatility, quiet performance, and reliability for distributed sound, clubs, restaurants, and home theater settings.
