The DLA speaker selector allows you to enhance your environment with rich audio in multiple locations. The DLA4 easily connects to your home theater/stereo receiver and up to four pairs of wired speakers routed throughout the home. The ATON DLA utilizes a logic circuit that actively monitors how many rooms are on, along with their respective volume levels, and delivers maximum available power to each room - simultaneously protecting the DLA and the amplifier from damage. Each DLA room output features an electronically controlled potentiometer, built with the highest-grade materials available to ensure super-flat frequency response and high power handling (125 W).
