The U.S. Acoustics Lisa is a compact, 4-channel Class AB car amplifier designed for warm, accurate audio reproduction with reduced distortion. Angled terminals simplify wiring, while Docking Pads reduce vibration and support reliability and amplifier lifespan.
Butterworth crossover filters provide high-pass and low-pass control. High-pass crossover range at 12 dB/octave: 15-500 Hz and 50-3K Hz; low-pass crossover range at 24 dB/octave: 55-3.5K Hz. The crossover listing specifies CH 3&4 and CH 1&2. Protection circuits cover thermal overload, short circuits, and DC offset.
RMS output: 50 W x 4 CH at 4 Ohms; 85 W x 4 CH at 2 Ohms; bridged mono at 4 Ohms: 170 W x 2 CH; mono at 1 Ohm: N/A. Input sensitivity: 200mV - 6.0V. Frequency response: 10Hz - 30KHz +/- 0.5dB. Total harmonic distortion: >0.01%; signal-to-noise ratio: > 95 dB; channel separation: > 85 dB; damping factor at 100Hz, 4 ohm: > 100. Subsonic: N/A; variable bass boost (0 to +12 dB at 45 Hz): No; wired remote bass control included: No; phase shift (0 - 180 degrees): No. Fusing: 2 x 25A. Size (L x W x H): 12.4" x 8.9" x 2.2".
