Congratulations!
And thank you for choosing this EMPHASER car audio amplifier!
To maximize the performance of this amplifier and your car audio system install, we recommend that you acquaint yourself thoroughly with all capabilities and features of the EMPHASER amplifier model you have chosen. Please read this manual carefully, before attempting the installation of this amplifier. Please retain this manual and your purchasing / installation receipts for future reference.
IMPORTANT NOTICE:
In case you are installing your EMPHASER amplifier by yourself, you should have your installation checked and approved by an authorized professional EMPHASER dealer/installer, in order to qualify for full warranty protection and also, to reach maximum power-output and audio performance possible with your individual car audio system.
1.DESIGN FEATURES
■CAR AUDIO Amplifier: This EMPHASER amplifier allows the crossover controlled amplification of satellite speaker systems, kickwoofer or subwoofer systems
■Dash-Mount Remote Lowpass Level Control: A compact „Lowpass-Level“ remote control unit can be mounted close to the drivers seat. This control device allows the convenient level adjustment of the bass volume (not applicable for EA480)
■FULL-MOSFET CIRCUITRY: This EMPHASER amplifier line features a full MOS-FET circuitry layout, implementing MOS-FET’s for power supply and output stages, to guarantee excellent sonic performance and very high power output
■Load Stability: This EMPHASER amplifier line up features models that work stable and reliable into very low impedance loads. Due to the high damping factor, every model of this amplifier line will guaranteed to have full control over the connected speaker system(s)
■Integrated Electronic CROSSOVER: The internal crossover section features independently selectable highpass or bandpass filtering, as well as fulllrange loop through. All x-overs feature crossover slope rates of 12/24 dB/octave
■Uncompromising Design AND CONSTRUCTION: Only best electrical and electronic components have been used for the assembly of this amplifier line. Such as double-sided glass-fiber epoxy circuit boards equipped with high current TR output devices.
■Advanced Protection Circuitry: The protection circuitry safe-guards the amplifier from short-circuits at the speaker outputs, DC offset voltage at the outputs and overheating of power electronics
■Status and Protection LED’s: A green and a red LED located at the side panel enable you to monitor the operating status of your EMPHASER amp
■Adjustable Input Sensitivity: Each RCA line-input pair accepts input voltages from 300mV to 7V, providing a good match to the line-output levels of almost any head-unit on the market
