DD Audio SA500.1

SA Series amplifiers are compact amplifiers with full size features. The SA500.1 is a 1 ohm stable monoblock subwoofer amplifier with a continous output power of 500 watts. Even though the SA Series amplifiers are very compact they still employ set screw power and speaker terminals, different input sections, and heavy duty aluminum heatsinks. This ensures power management is proper from input to output, increasing both in-use stability and long term durability. - Mosfet power supply amplifier - 4 gauge set screw power terminals - 12 gauge set screw speaker terminals - Variable 12dB/oct crossovers - Remote subwoofer control (SA500.1) - 5-way protection: Speaker short, thermal, overload, HI/LOW voltage, DC offset Class: D-class amplifier Operating voltage: 9-16 Test voltage: 14.4 Output Channels: 1 Cont wattage @4Ohm: 250 Cont wattage @2Ohm: 390 Cont wattage @1Ohm: 500 Dynamic wattage: 1000 Max current draw - Amps: 50 RCA input sensivity - Volts: 6 - 0.25 High level sensivity - Volts: 20 - 1.1 Frequency response - Hz: 85 S/N Ratio -dB: 70 Damping factor: 10 - 250 THD: 0.1% Boost level: 12dB @ 45Hz High pass filter - NA Subsonic filter - Hz: 10 - 50 Low pass filter - Hz: 35 -250 Remote subwoofer control: Yes Power wire gauge - IN: 4 Speaker wire gauge - OUT: 12 Dimensions - in 7 x 3.8 x 1.69 Dimensions - mm 180 x 96 x 43
