The Line Magnetic LM-325N is a stereo power amplifier delivering 18 W plus 18 W into 8 ohms. It is meant to sit after a preamp or volume-controlled source and power two speakers.

Key specs that matter

XLR and RCA connections are provided, and each offers a selectable input impedance of 100 kOhm or 600 ohms. The frequency response extends from 10 Hz to 45 kHz at -3 dB.

Engineering and use context

The 600 ohm setting suits sources designed to drive a low-impedance, professional-style load, while 100 kOhm is the usual choice for domestic preamplifiers. The chassis measures 480 x 490 x 275 mm and weighs 52 kg, a lot of mass for this output, so plan for a sturdy support.

Pairing

With this modest output, the LM-325N is best matched with efficient loudspeakers that present an easy load.
