The RA1-280.4 is a 280 watt car audio amplifier. Reference amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit.\u003c\/p\u003e\n\u003ch4\u003ePower your music\u003c\/h4\u003e\n\u003cp\u003eMB Quart's Reference Series RA1-280.4 four-channel amplifier provides 50 watts of power to two pairs of speakers, so you can hear and feel your music clearly over road and engine noise. Designed to power high-quality aftermarket speakers, like their Reference Series speakers and components, this Class D amplifier utilizes MB Quart's unique Q-Stasis (Class SQ) circuitry to improve the accuracy and clarity of your music.\u003c\/p\u003e\n\u003ch4\u003eVersatile features\u003c\/h4\u003e\n\u003cp\u003eThe amplifier's features include speaker-level inputs with signal-sensing amp turn-on, so it's ready to work in almost any system. A high-pass filter shapes the signal to fit your full-range speakers for their best-sounding output. You can also configure this amp for two-channel operation to power a pair of subwoofers with up to 140 watts each or for three-channel operation to power a pair of speakers with 50 watts each while powering a sub with 140 watts. A low-pass filter and a bass boost EQ help dial in just the right kind of bass bump you like.\u003c\/p\u003e\n\u003ch4\u003eRA1-280.4 Features:\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eLow Noise Preamplifier Circuit:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eQ-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRCA Inputs: Nickel-Plated:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHigh temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Level Inputs:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSee Auto-Sense Feature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2 \/ 4 Channel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrossover Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eVariable electronic crossovers allow for complete control of the sound.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectronic Equalizer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eControl of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers.
