This little guy churns out 100 watts of audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eThe JD400\/4’s controls can be found on the input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminum chassis. Signal processing features include high or low-pass 12 dB \/ octave filters (defeatable) for each channel pair, with continuously variable frequency selection from 50-500 Hz, and dual-range, differential-balanced inputs capable of accepting line-level or speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eOnboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenient feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier.\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eFrequency Response: 12 Hz - 22 kHz (+0, -1 dB)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eS\/N Ratio, referred to highest rated power: \u0026gt; 104 dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eS\/N Ratio, referred to 1 W: \u0026gt; 84 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eDamping Factor @ 4 Ω: \u0026gt; 150 \/ 50 Hz\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eDamping Factor @ 2 Ω: \u0026gt; 75 \/ 50 Hz\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eTHD+N @ Rated Power: \u0026lt; 1% @ 2 Ω per Ch.\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eInput Voltage Range @ RCA Inputs: Switchable from 200 mV - 2 V RMS (Low) to 800 mV - 8 V RMS (High)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003eMin.
