ELEKTRA d4.100AB, d2.200AB, d1.1200D Product Manual

Troubleshooting

Problem Solution

Power LED off

Check the fuses, power cables and remote for correct

voltage, loose power connections
No Output (Power
LED is on)

Check the head unit for output, gain settings, RCA

connections, speaker cables and connections
No Output (Protect
LED is on)

Speakers may be shorted or damaged; amplifier may

be overheated or overloaded. Check for low voltage

Weak bass

Check speaker polarity and phase, crossover

settings, bass settings on the head unit
Amplifier switches
on and off

Check ground connection, power cable connections

and voltage, remote wire connection

Distorted output

Check gain settings on source and amplifiers.

Speakers may be also damaged.

Reference Amplifiers

Features

The  4.100AB,  2.200AB &  1.1200D delta ( ) series amplifiers
are Elektra’s reference car audio amplifiers. The  4.100AB is a 4
channel class AB amplifier that outputs 100W RMS x 4 into 4 ohms.
The  2.200AB is a 2 channel class AB amplifier that outputs 200W
RMS x 2 into 4 ohms. The  1.1200D is a monoblock class D
amplifier that outputs 1200 W RMS x 1 into 1 ohm.

The  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  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

 4.100AB Connections

 1.1200D 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)

11. Slave Output – connect to the slave amplifier (only when strapping)

12. Power Indicator – this indicates if the amplifier is running optimally

13. Protection Indicator – this indicates a problem. If this lights up, shut
down the amplifier to troubleshoot the problem.

14. Fuses – If blown, replace only with the same value and type of fuses

15. Phase – adjust this to control the output polarity

16. CH1/2 RCA input – connect to your CH1 and CH2 RCAs

17. CH3/4 RCA input – connect to your CH3 and CH4 RCAs

18. HPF/LPF switch – choose FULL, HPF or LPF crossover mode for CH1/2

19. HPF/LPF switch – choose FULL, HPF or LPF crossover mode for CH3/4

20. Gain Control – adjust this to control the gain for each channel pair

21. 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.
