d4.100AB Four Channel Amplifier
Features
The delta (d) series amplifiers are Elektra’s reference car audio amplifiers.. The d4.100AB is a 4 channel class AB amplifier that outputs 100W RMS x 4 into 4 ohms.
The d series amplifiers feature high power and high efficiency MOSFET circuit design with overload, short circuit, thermal and low voltage protections. An optional bass remote control is available separately.
The d series amplifiers are designed with a double sided PCB in a symmetrical layout, Toshiba outputs, 105°C capacitors and Tiffany-style RCA connectors in a black and gold brushed aluminum chassis.
