Need help?Do you have a question about the EMPHASER EA2160S and is the answer not in the manual?
Enables crossover-controlled amplification for satellite speakers, kickwoofers, and subwoofers.
Features selectable highpass/bandpass filtering with 12/24 dB/octave slopes and full-range loop.
Built with high-quality electronic parts and double-sided glass-fiber epoxy circuit boards.
Safeguards amplifier against short-circuits, DC offset voltage, and overheating.
Includes green and red LEDs on the side panel for monitoring operating status.
Accepts input voltages from 300mV to 7V for versatile head-unit matching.
Details front panel controls: Power LED, Gain, HPF, X-Over, LPF, RCA Inputs, Operation Mode, Remote Port, Protection LED.
Describes rear panel terminals: Speaker Outputs, GND, Remote Input, and +12V Power Input.
Outlines front panel controls for the 4-channel EA4160s, including dual gain and crossover adjustments.
Explains rear panel terminals for EA4160s: Speaker Outputs, GND, Remote Input, and +12V Power Input.
Provides recommended impedance ratings and main power wire gauge for optimal amplifier operation.
Disconnect battery and fuse before wiring; ensure secure mounting away from hazards.
Choose a location with proper ventilation, clear of wiring harnesses and fuel tanks.
Use the unit as a template for pilot holes; ensure solid ground and avoid heatsink contact with the vehicle.
Connect +12V and ground wires securely, using a main fuse within 30cm of the battery.
Route RCA and remote wires separately from power cables, connecting them to the head-unit and amplifier.
Connect speaker wires to terminals, ensuring correct polarity and checking LED indicators post-installation.
Choose HIGHPASS, BANDPASS, or FULL(range) based on speaker system configuration.
Set HPF between 50-150Hz for satellite speakers to manage bass frequencies.
Adjust LPF (BPF mode) between 60-90Hz for subwoofers and set subsonic filter to lowest.
Utilize the HPF potentiometer for subsonic highpass frequency in BANDPASS mode.
Set tone controls to neutral, then adjust GAIN to match head-unit output for optimal dynamics.
