UP 2162 is a device with 2 separated and independent 160 W amplifiers, each having 2 audio inputs, of which one with priority function through a closing contact. Both the audio inputs are at ‘line’ level: for pre-amplified signals or music sources (e.g. CD players, tuners, etc.).The amplifier output is available either for low impedance loudspeakers (min. 4 O) or 100 – 70 V constant voltage line (for loudspeakers having 100 – 70 V transformers). The amplifier is Class D with switching power supply; the overall weight is extremely reduced plus it offers a wide audio bandwidth quality.
