The versatile Class A/B RL-LA400.4 will drive DD REDLINE Series Coaxials and components with warm, accurate sound. For added versatility, we’ve included an RCA pass through for chaining to a second amplifier, and the rear channels can be bridged to drive a subwoofer for a complete audio upgrade from a single amplifier!
When paired with a DD AUDIO SC2 or SC4 active line output converter, the REDLINE LA Series amplifiers provide a seamless factory integrated amplification solution.
The REDLINE LA Series amplifiers utilize spade terminals for clean and secure connections on both the power input and speaker outputs.
