Product Description
DLS Ultimate A4 - 880Watts 4 CH Amplifier
DLS ULTIMATE series A4 is a powerful 4-channel amplifier. The amplifier is 1 ohm stable and provides a power output 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 subwoofers on all channels.
- Additionally, 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 on the filter can be switched so that two of the channels can be used for mid-range woofers.
- Dual power terminals where you can connect dual power feeds or a DLS Power Cap.
- Output for electronically controlled cooling fan.
- RMS output per channel at 13,8 volts, 20 Hz - 20 kHz , < 0,1% distortion.
The Ultimate series amplifiers are known for the good sound quality with a detailed, high resolution sound. The amplifiers are often used in SQ competitions in both IASCA and EMMA competitions. The amplifiers are used in cars winning both European and World championsships.
