DLS ULTIMATE A4 – The Big Four 4-channel amplifier ULTIMATE series A4 is a powerful 4-channel amplifier. The amplifier is 1 ohm stable and provides an output power of 4 x 85 Watts with 4 ohm stereo and 2 x 250/400 Watts with 4/2-ohm mono bridge-connection. Built-in variable 50-125 Hz low-pass filter for subwoofer on all channels.
In addition, a built-in variable 20-200 Hz high-pass filter that can be used as a subsonic filter or high-pass filter for front systems.
The frequency of the filter can be switched so that two of the channels can be used for mid-range woofer. Dual power terminals where you can connect dual power feeds and DLS Power Cap.
