The Lone Audio LA-2120D packs a Class-D stereo amplifier rated at 2 x 120 W into 4 ohms and a mixer with a media player offering Bluetooth, USB and an FM tuner into a 1U rack unit for playback and announcements without extra hardware.

The front panel carries a 3.5 mm mini-jack AUX input plus controls for media volume, microphone/line level, AUX 1 and AUX 2, treble, bass and master. Three MIC/line inputs on XLR with selectable phantom power sit alongside two L/R RCA AUX inputs; outputs include two L/R XLR connectors, an RCA REC output and a 24 V mute contact.

The unit targets high audio quality with harmonic distortion below 0.5% and S/N ratios of at least 55 dB on the microphone and 60 dB on AUX/line. The fan cooling system and integrated protections against overloads, short circuits and overheating ensure reliability and safety; cooling is by forced convection. With compact dimensions and a weight of 1.96 kg it can be mounted in a 1U rack.

A Bluetooth interface and USB socket on the front panel allow multimedia playback without additional devices; three XLR microphone inputs with phantom power and various AUX and line options complete the input section. Compact design and audio quality suit installations in restaurants, shops, hotels and commercial activities.
