Усилители мощности стерео — Line Magnetic AS-128PP

The Line Magnetic AS-128PP is a stereo power amp with a rating of 2 x 120 W into 8 ohms. It is a heavy, full-width unit intended to drive a pair of loudspeakers from a separate preamplifier or source with its own volume control.

Key specs that matter

Input sensitivity is 500 mV and the single-ended input impedance is 100 kOhm, an easy load for most preamplifiers. Gain can be switched between two settings, listed as 51 and 63. The frequency response runs from 10 Hz to 70 kHz at -3 dB. The S/N figure is 88 dB, and THD plus noise is 1 percent with global feedback applied.

Engineering and use context

The chassis measures 480 x 280 x 530 mm and weighs 80 kg, so it needs a solid, low shelf or floor placement and two people to move it. The switchable gain helps match the amplifier to sources and preamplifiers with different output levels.
