d1.1200D Monoblock Amplifier
Features
The delta (d) series amplifiers are Elektra’s reference car audio amplifiers. The d1.1200D is a monoblock class D amplifier that outputs 1200 W RMS x 1 into 1 ohm, or 2400 W RMS x 1 into 2 ohms (strapped).
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
- Output Terminals – connect to your speakers using at least 16AWG wire
- +12V Power Terminal – connect using a fused 4AWG to the battery +ve
- Remote – connect to the remote wire to turn the amplifier on/off
- Ground Terminal – connect using 4AWG to an electrical/chassis ground
- Line Input – connect to your source’s RCA cables
- Remote Bass Control – connect to your optional bass remote
- Low Pass Filter – adjust this to filter out unwanted high frequencies
- Subsonic Filter – adjust this to filter out unwanted low frequencies
- Bass Boost – adjust the bass boost level between 0dB to 12dB
- Master Input – connect to the master amplifier (only when strapping)
- Slave Output – connect to the slave amplifier (only when strapping)
- Power Indicator – this indicates if the amplifier is running optimally
- Protection Indicator – this indicates a problem. If this lights up, shut down the amplifier to troubleshoot the problem.
- Fuses – If blown, replace only with the same value and type of fuses
- Phase – adjust this to control the output polarity
- CH1/2 RCA input – connect to your CH1 and CH2 RCAs
- CH3/4 RCA input – connect to your CH3 and CH4 RCAs
- HPF/LPF switch – choose FULL, HPF or LPF crossover mode for CH1/2
- HPF/LPF switch – choose FULL, HPF or LPF crossover mode for CH3/4
- Gain Control – adjust this to control the gain for each channel pair
- Crossover – adjust this to control the HPF/LPF crossover frequency
Strapping TWO ?1.1200D’s: Connect source’s RCAs to the master amplifier only. Connect a single RCA cable from the master amplifier connection to slave amplifier connection (from #11 to #10 in connection diagram).
Connect the master amp +ve to the subwoofer +ve, the slave amp +ve to the subwoofer –ve and then connect the master amp –ve to the slave amp –ve.
