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 bve
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.

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 subve
, the
slave amp +ve to the
subwoofer –ve
and then connect the
master amp –ve to the slave amp –ve
.
