About: DS18 SMD-200.4AB 4-Channel Class AB Amplifier with Voltmeter and Digital LED Lights
Introducing the SMD-200.4AB— engineered by DS18 in collaboration with Steve Meade Designs. Built for superior audio performance, it features premium Korean components and Sky High Car Audio’s OFC Internal Wiring. With DS18’s reputation as the LOUDEST in pro audio and Steve Meade’s industry-standard installation peripherals, this amp is built for extreme power and convenience.
Manufactured using premium components from Korea, this amplifier guarantees the reliability and powerful sound quality that Steve Meade Designs is known for. The SMD-200.4AB is not only visually striking but also engineered for top-tier performance. It delivers an impressive 150W x 4 RMS at 4-ohm, 200W x 4 RMS at 2-ohm, and 400W x 2 RMS bridged at 4-ohm: driving even the most demanding setups with ease.
The SMD-200.4AB is designed for audiophiles seeking superior sound quality. As a Class AB amplifier, it prioritizes clarity and detail, delivering pristine audio performance. Equipped with a precision attenuation knob for easy bass control, it maintains a .10% THD, ensuring exceptional Total Harmonic Distortion levels. With 4 AWG power and ground inputs and a 120A fusing requirement, it’s built for robust power delivery. Additional features include selectable 2/4 channel inputs and Tiffany RCA connectors for the highest quality signal transfer in your setup.
