For 4CH mode, Group A (CH1 and CH2) and Group B (CH3, CH4) both require stereo
input signal. All 4 channels will work independently.
For 2CH mode, Only Group A (CH1 and CH2) requires stereo input signal, Group B
(CH3, CH4) will receive the same signal as Group A. 2CH model is for source unit
that has only 1 stereo output signal.
The amplifier has dual input sensitivity differential inputs which will
receive either
High level (Speaker output) or Low level (RCA) signals from your car stereo's source
unit
.
When switch to PRE IN, The signal can be delivered to the amplifier using the low-
level
RCA outputs on the source unit
.
When switch to SPK IN, The high-level signal can be run from the source unit's
speaker outputs to the stereo RCA input on the end panel of the amplifier using the
HL01.

REM:
When auto turn on to REM, please connect the unit REM terminal to the source
unit remote terminal with an 18AWG cable. This is the preferred mode.
DC OFFSET:
If the OEM source unit has no REM signal output, you can choose DC
OFFSET (Meanwhile, Input select switch to SPK IN mode) , DC OFFSET can turn
on/off EA series amp by detecting the 6V DC Offset from the OEM source unit
terminal.
AUDIO:
Audio mode can turn ON/OFF D1600.4 amp by detecting the audio signal
from source unit.
Note
: If the volume is too Low, The amp may fail to turn on. So
please check if the source unit volume is properly set.
