Stereo Integrity

Stereo Integrity SIQ 200.2 Amplifier: Purity and Power in Two Channels The Stereo Integrity SIQ 200.2 brings true high-fidelity audio engineering back to mobile sound systems. Built by audiophiles for the most discerning listeners, this powerful 2-Channel Class A/B amplifier prioritizes signal integrity above all else. Its design features zero filters, zero crossovers, and zero EQ, delivering a full bandwidth signal (5 Hz to 150,000 Hz) that is clean, precise, and uncompromised. This is the foundation for an accurate soundstage and breathtaking sonic detail. Uncompromised Audiophile Construction Every component in the SIQ 200.2 was selected based on its acoustic performance and long-term durability: Output Transistors: Utilizes audiophile-grade TO-3 output transistors for clean, linear power delivery. Internal Circuitry: Features high-quality UPC4570 op-amps, IRFPO64N power supply transistors, and sand cast resistors throughout the construction. Aesthetics: Protected by a thick extruded aluminum chassis with a copper anodized shielded transformer cover to minimize electromagnetic interference, all visible through a large plexiglass viewing window. High Power, Ultra-Low Distortion Performance The SIQ 200.2 delivers robust power with unmatched fidelity, validated by Audio Precision measurements: Rated RMS Power Output (2 Channels): 200W RMS x2 @ 4Ω High Current Output: 400W RMS x2 @ 2Ω Bridged Monoblock Power: 800W RMS x1 @ 4Ω Total Harmonic Distortion (THD): 0.03 % (Exceptional clarity) Signal-to-Noise Ratio (SNR): 92 dB Installation and Specifications Purity Control: Features a discrete gain knob per channel for precise level matching. Connections: Premium Tiffany-style RCA connections accepting inputs up to 16 Volts. Dimensions: Compact size at 14 x 8 x 2 Inches. Current Draw: Maximum current draw of 85.6 amps. The SIQ 200.2 is the ultimate 2-channel solution for audiophiles seeking true, powerful sound reproduction in their vehicle.   Amplifiers Specifications Frequency Response Minimum 5 Hz Frequency Response Maximum 150,000 Hz Signal-to-Noise Ratio (SNR) 92 dB Total Harmonic Distortion (THD) 0.03 % Dimensions (W x H x D) 14 x 8 x 2 Inches Rated RMS power output into all 4 channels at 4 ohm 200 Watts Rated RMS power output into all 4 channels at 2 ohm 400 Watts Bridged RMS power into 2 channels at 4 ohm 800 Watts Power Idle Current Draw 1.3 amps Maximum Current Draw 85.6 amps   Connections RCA Input Maximum 16 Volts
