2. CONNECTIONS + TOP CONTROLS EA1300
2.1 INPUTS + OUTPUTS
1 CINCH MASTER / SLAVE IN-OUT
Master Slave RCA sockets to connect at least two EA1300 amps in Master / Slave
mode. Master / Slave mode allows to drive one amp with RCA input signal from the
head unit, and to daisy chain all further amps of the system.
To connect in Master / Slave mode, a mono RCA interconnect cable is required. See
connection drawing on page 28.
2 RCA INPUTS 1/2-CH
Low-level stereo RCA signal input 1/2-CH for connection to head-unit.
3 REMOTE CONTROL INPUT
Input terminal to connect the external bass level remote to the amplifier.
4 HIGH INPUT
Molex connector terminal to insert the High level adapter (4-Pin) that picks up the
amplified speaker signals from the head unit's front and rear outputs (if head unit
does not feature dedicated RCA line outs).
5 SPEAKER OUTPUT TERMINAL
Output terminal to connect the speakers to the amplifier in either stereo or bridged
mode. For bridge connection, use the terminals with fat polarity signs.
6 ATC FUSE HOLDER
Fuse holder for 2 x 25 A ATC fuses. Never deploy fuses of higher amperage rating.
7 "+12 V" POWER INPUT TERMINAL
Terminal to connect the amplifier to the positive +12 V pole of the car battery.
8 "REM" INPUT TERMINAL
Terminal to connect the amplifier to the automatic (remote) turn-on / turn-off lead of
the head unit.
9 "GND" POWER INPUT TERMINAL
Terminal to connect the amplifier to the chassis ground or negative pole of the car
battery.

2.2 TOP CONTROLS
1 INPUT GAIN CONTROL CH1/CH2
Input gain potentiometer for channel CH1/CH2, to match the output voltage of the
head-unit to the amplifier's input.
2 PHASE SWITCH CH1/CH2
Switch to select normal or inverted phase for section CH1/CH2 of the amplifier.
3 X-OVER FREQUENCY CONTROL CH1/CH2
Control potentiometer to adjust the lowpass filtering frequency point for section
CH1/CH2 of the amplifier.
4 SUBSONIC HIGHPASS FREQUENCY CONTROL
Control potentiometer to adjust the subsonic highpass filtering frequency point for
section CH1/CH2 of the amplifier.
5 POWER LED
LED bar segment to show "operating" status of the amplifier by red illumination.
Protect state of amplifier is signaled by blue state.
