Amp Car Amplifier

Make a Powerful Sound StatementPanasonic's line of power amps expands even further to include digital technology. High efficiency is a key requirement for amplifiers, particularly when it comes to driving a powerful subwoofer over long periods using the car's battery power. Compared to the 45% to 55% efficiency of a conventional analog amp, a "digital" amp can attain over 70% to 80% efficiency by converting the input signal to a pulse signal and operating its output stage in "class D" or switching mode. Maximum output power is an impressive 1100W to provide effortless subwoofer drive, thanks to high efficiency with low heat generation and reduced load on the car battery.Low-Pass Filter for SubwooferAmps with a built-in low-pass filter simplify upgrading to a subwoofer system. You can adjust the cutoff frequency continuously from 50Hz to 250Hz for optimum matching between the subwoofer's range and that covered by your other speakers.Line-Out Jacks for ExpansionWhen configuring a sophisticated car audio system, line-out jacks make all of the difference. They let you easily connect multiple amps, while keeping the wiring neat for an attractive appearance."Intelligent" Bass Servo CircuitIn comparison with the midrange and tweeter units, the woofer has a relatively higher moving mass, heavier voice coil and larger inductance, so it needs more current to start moving. This causes the bass to lag behind the mid and high frequencies, resulting in unnatural tonal coloration. Furthermore, because of its longer throw, the woofer's voice coil has a greater tendency to deviate from pistonic motion, resulting in non-linear dynamic distortion. To overcome these woofer shortcomings, our "intelligent" bass servo drive circuit can feed very high current at the moment of start-up and instantaneously detect and correct the state of voice coil movement to maintain pistonic motion and avoid non-linearity. The result is bass that is more coherent with the rest of the frequency spectrum, achieving greater fidelity to the original sound.Digital Technology Power Output (maximum) 1100W Power Output (at 4O and = 1% THD+N) 350W x 1 Signal to Noise Ratio (1W into 4O) 85dBA THD (1kHz) 0.02% Frequency Response (Â±1.0dB) 10Hz - 30kHz Crossover Frequencies 50Hz - 250Hz Bass Boost 0dB - 15dB Input Level Adjustment 200mV - 6V Speaker Impedance 4O Current Consumption 24A (350W x 1, 4O) Line-Out Jacks Gold-plated RCA Connectors Gold Plated Speaker Terminals Speaker Level Input Servo Drive Circuit, for PWM DC-DC converter Thermal shutdown protection circuit Indication LED Illumination Blue Dimensions (H x W x D) 2 7/16"'' x 11 15/16"'' x 11"''

Make a Powerful Sound StatementHigh efficiency is a key requirement for amplifiers, particularly when it comes to driving powerful speakers over long periods using the car's battery power. To attain high efficiency, the power supply drive stage employs MOS-FET devices having low internal impedance. This helps preserve the transparency and crispness of the original audio signal for faithful audio reproduction through the connected speakers. Maximum output power is an impressive 1000W (250W x 4), thanks to high efficiency with low heat generation and reduced load on the car battery.Low-Pass Filter for SubwooferAmps with a built-in low-pass filter simplify upgrading to a subwoofer system.

Drive four speakers, two speakers, or two speakers and a subwoofer, the choice is yours. This amp has the flexibility to fit your car audio system.Power Output (maximum) 225W x 4 Power Output (at 4O and = 1% THD+N) 64W x 4 Signal to Noise Ratio (1W into 4O) 85dBA THD (1kHz) 0.02% Frequency Response (Â±1.0dB) 10Hz - 30kHz Crossover Frequencies 50Hz - 250Hz Bass Boost 0dB - 15dB Input Level Adjustment 200mV - 6V Speaker Impedance 4Ã™ Current Consumption 24A (64W x 4, 4O) Line-Out JacksGold-plated RCA Connectors Gold Plated Speaker Terminals Speaker Level Input Mix Mode Operation Bridgeable 4-, 3- or 2-channel Servo Drive Circuit Yes, for PWM DC-DC converter Thermal shutdown protection circuit Yes Indication LED Illumination Blue Dimensions (H x W x D) 2 7/16"'' x 13 1/8"'' x 11"''

Current-feedback operational amplifier - The current feedback operational amplifier or CFB op-amp is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback (VFB) operational amplifier. The CFB op-amp was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.

Operational amplifier - An operational amplifier or op-amp is a very high-gain amplifier which has two inputs, one inverting (âˆ’) and one non-inverting (+). The output voltage is the difference between the + and âˆ’ inputs, multiplied by the open-loop gain:

AmpÃ¨re (car) - The AmpÃ¨re was a French automobile built at Billancourt from 1906 to 1909. The car featured a 10/16hp four-cylinder engine driving through an electric clutch; according to the advertising material, this made for "variation of speed by electric transmission, with neither dynamo nor accumulators.

Bluebird Compartment Car (New York City Subway car) - The Bluebird, formally dubbed Compartment Car by its purchaser, the , was an advanced design PCC subway and elevated railway car used on the New York City Subway system from 1939 to 1962.
