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.
