This 4/3/2-channel amplifier is designed for flexible, powerful audio performance. It features low-level (0.25-6 V) compatible RCA inputs for versatile connectivity. With power ratings of 4 x 70 Watts RMS into 4 Ω, 4 x 110 Watts RMS into 2 Ω, and bridge configuration power of 2 x 230 Watts RMS into 4 Ω, this amplifier ensures optimum sound reproduction for your loudspeakers. The amplifier covers an extended frequency response from 10 Hz to 30 kHz, with low-pass (50 Hz – 250 Hz) and high-pass (50 Hz – 250 Hz) filters to fine-tune frequencies. It boasts a signal-to-noise ratio in excess of 90 dB and a total harmonic distortion (THD) of less than 0.05%, guaranteeing superior sonic clarity. It is protected against short circuits, low impedance, overheating and reverse polarity. The amplifier dimensions are 174 x 158 x 99 mm (6.85“ x 6.2” x 3.9″). Instructions for use are included for easy installation.
