2. CONNECTIONS + TOP CONTROLS EA485
2.1 INPUTS + OUTPUTS
1 RCA INPUTS 1/2-CH + 3/4-CH
Low-level stereo RCA signal input 1/2-CH and 3/4-CH, for connection to head-unit.
2 HIGH INPUT
Molex connector terminal to insert the High level adapter (8-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).
3 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.
4 ATC FUSE HOLDER
Fuse holder for 1 x 40 A ATC fuse. Never deploy fuses of higher amperage rating.
5 “+12 V” POWER INPUT TERMINAL
Terminal to connect the amplifier to the positive +12 V pole of the car battery.
6 “REM” INPUT TERMINAL
Terminal to connect the amplifier to the automatic (remote) turn-on / turn-off lead of
the head unit.
7 “GND” POWER INPUT TERMINAL
Terminal to connect the amplifier to the chassis ground or negative pole of the car
battery.
8 “FAN”
Internal fan to cool and safeguard amplifier electronics against overheating.
2.2 TOP CONTROLS
1 INPUT GAIN CONTROL 1/2-CH

head-unit to the amplifier’s input.
2 OPERATION MODE SWITCH 1/2-CH
Slide switch to select the operation mode of the X-over for section 1/2-CH of the
amplifier.
3 X-OVER FREQUENCY CONTROL 1/2-CH
Control potentiometer to adjust the highpass or lowpass filtering frequency point for
section 1/2-CH of the amplifier.
4 INPUT GAIN CONTROL 3/4-CH
Input gain potentiometer for channel 3/4-CH, to match the output voltage of the
head-unit to the amplifier’s input.
5 OPERATION MODE SWITCH 3/4-CH
Slide switch to select the operation mode of the X-over for section 3/4-CH of the
amplifier.
6 X-OVER FREQUENCY CONTROL 3/4-CH
Control potentiometer to adjust the highpass or lowpass filtering frequency point for
section 3/4-CH of the amplifier.
7 PHASE SWITCH 3/4-CH
Switch to select normal or inverted phase for section 3/4-CH of the amplifier.
8 SUBSONIC HIGHPASS FREQUENCY CONTROL 3/4-CH
Control potentiometer to adjust the subsonic highpass filtering frequency point for
section 3/4-CH of the amplifier.
9 POWER LED
LED bar segment to show “operating” status of the amplifier by red illumination.
Protect state of amplifier is signaled by blue state.
