Incriminator Audio Incriminator Audio IX3.4 4-Channel Amplifier
Incriminator Audio IX3.4 Amplifier The all new Incriminator Audio IX3.4 is the new answer to compact, premium 4 channel amplifiers. All the features of the outstanding IA 3.4 but with more power and less size, updated to the new IX series standards. When we say compact, we are not joking around. The new IX3.4 is trimmed down to a miniscule footprint of less than 8”. That saves you space but doesn’t cut down on the traditional high quality build we are known for in our world famous amps. One thing you don’t have to worry about is the crossovers, as we still have the same level of flexibility in the crossover network our customers have come to expect from our multi-channel amplifiers. Which means, you will have high-pass / full range / low-pass crossover settings for both pairs of channels, as well as subsonic filter. We didn’t stop at the size, why not improve the power too? That is exactly what we did, by bumping up the power on the IX3.4 to 100 watts x 4 channels at 4 ohm and 340 watts x 2 at 4 ohms. The great news is the new Class-D design is very efficient and very low distortion, so you will only need a mere 50 amps of fusing for the all new IX3.4 while hearing all the right notes. All of this adds up to an easy decision when it comes to needing a high quality, compact, flexible, and powerful 4 channel amplifier in the IX3.4. *Please note- This amplifier ships directly from Incriminator Audio. Please allow an addition 1-2 day processing for this amplifier.* Features Full Range Class D Amplifier Dual MOS-FET Pulse Width Modulation Power Supply 2 Ohm Stable Stereo / 4 Ohm Mono Topology 12 dB/octave - Variable State Subsonic Filter 12 dB/octave - Variable State Low / High Pass Filter Flexible Crossover Multipliers X1 / X10 Heavy Duty Copper Layer Double Sided Epoxy PCB Mirror Techology (Channel 1/2 to 3/4) Individual Clipping Indicators Multi-Layer Bullet Proof Protection Circuit Wired Remote Control with Clipping Indicator Specifications Rated Power ( 14.4V at 1% THD ) RMS Power - 2 Ohm Mono : 340W x 2CH Bridged RMS Power - 2 Ohm Stereo : 170W x 4CH RMS Power - 4 Ohm Stereo : 100W x 4CH Low Pass Filter ( 12dB/Oct. ) : 50Hz - 5000Hz ( X1, X10 ) High Pass Filter ( 12dB/Oct. ) : 50Hz - 5000Hz ( X1, X10 ) Subsonic Filter ( 12dB/Oct. ) : 10Hz - 500Hz Frequency Response ( +/-1dB ) : 20Hz - 28,000Hz Channel Separation : 55dB Input Sensitivity ( Volt +/- 5% ) : 6.0V - 0.2V Signal / Noise Ratio : 92dB Dampening Factor ( 4 Ohm ) : 100 + Operation Mode : Mirror CH1/2 > CH3/4 Power Efficiency ( 4 Ohm ) : 90% Fuse Rating ( 14.4V ) : 50A Power Input Connection : 4 Gauge Operation Voltage : 8.5V - 16.0V Speaker Output Connection : 8 Gauge Dimensions ( Inches ) : 7.48 W x 2.24 H x 7.48 L Dimensions (Millimeters) : 190 W x 57 H x 200 L
