Low Noise Preamplifier Circuit

Adopt AKM multi DSP Technology AKM is a professional DSP ADC DAC chip developer and manufacturer. Its chips are widely used in high-end audio products and high-end mobile phone audio processing • High speed 24-BIT ADC DAC • 192K sampling frequency • high frequency sampling enables better reproduction of sound details • CSR 5.0 aptx Bluetooth • Qualcomm's proprietary high-definition Bluetooth transmission technology enables lossless transmission of audio to DSP • IOS / Android app allows a convenient and fast control of the DSP.

RCA Inputs

Nickel Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.

High Level Inputs

DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off.

Operation Mode

4 Channel operation

Output Device Technology

FLUID-FETS: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.

Heat Sink

Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.

Power Supply

Direct use of vehicle power supply, increase of high-efficiency power filter isolation, make the power supply of power amplifier clean and undisturbed.

Output Connections

Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.
