KAC-M1814
Compact 4-Channel Digital Amplifier
The Multi-Application KAC-M1814 Compact 4 channel Class-D amplifier with 400 peak power supports louder volume for Car, Marine and Motorsports users with low-noise. Plastic covered connector helps to keep out water and dust and the Conformal Coating provides vibration resistance and helps prevent the PCB from rusting.
RCA Line-In terminal or Speaker Level Input, with Signal Sensing Turn-on, to connect any type of receiver. A.ch and/or B.ch Filter Frequency Control and Filter Switch to apply HPF / OFF / LPF. Bridgeable Connection. Pre-amp and Power-amp sections are separated to reduce radiation noise.
Multi-Application
Compact design with controlable interface to adjust the sound from a receiver.
① Filter Frequency Control (A.ch/B.ch)
② Filter Switch to apply HPF / OFF / LPF (A.ch/B.ch).
③ Line In terminal
④ Input Sensitivity Control (A.ch/B.ch)
Conformal Coating
Conformal coating is a special film that protects circuit boards, components, and other electronic devices from adverse environmental conditions.
It provides increased dielectric resistance, operational integrity, and protection from corrosive atmospheres, humidity, and airborne contamination such as salt-spray, dirt and dust.
