d4.100AB 4 Channel Amplifier


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.

Connections

4ch Connections
  1. Output Terminals – connect to your speakers using at least 16AWG wire
  2. +12V Power Terminal – connect using a fused 4AWG to the battery +ve
  3. Remote – connect to the remote wire to turn the amplifier on/off
  4. Ground Terminal – connect using 4AWG to an electrical/chassis ground
  5. Line Input – connect to your source’s RCA cables
  6. Remote Bass Control – connect to your optional bass remote
  7. Low Pass Filter – adjust this to filter out unwanted high frequencies
  8. Subsonic Filter – adjust this to filter out unwanted low frequencies
  9. Bass Boost – adjust the bass boost level between 0dB to 12dB
  10. Master Input – connect to the master amplifier (only when strapping)
