FOSI AUDIO LC30 Audio Selector Switch for Amplifiers / Speakers Yellow vu-meter

Fosi Audio LC30 picture

With its LC30, Fosi Audio unveils an amplifier and speaker selector. In other words, it allows you to switch easily and quickly between two power amplifiers and two pairs of passive speakers. This device is ideal if you want to take advantage of two Hi-Fi systems, or if you want to carry out comparative tests. Fosi Audio has chosen to integrate two relatively impressing VU meters on the front of its LC30 to give it a vintage look. The LC30 also features a remote control for added convenience and a comfortable user experience.

In terms of technical specifications, the LC30 supports up to 2x 250W under 4ohm power and is compatible with most power amplifiers on the market: class A amplifiers, class A/B amplifiers, class B amplifiers, class D amplifiers, mono amplifiers (BTL) and tube amplifiers. A large potentiometer adjusts the intensity of the VU meters according to the input signal power, and a 4-level light intensity setting (100%, 75%, 50%, Off) is also available. All LC30 components are housed in a durable aluminum case.

Du plus bel effet
Je ne l'ai acheté que pour mettre un vu mètre, et c'est parfait vintage old school bien un truc de vieux comme disent mes gosses.
Les réglages sont simples, luminosité adaptable, les aiguilles synchro avec le son, tout est parfait !

Good switcher but disappointing VU meter sensitivity
Unit was delivered with a loose screw inside. Not very nice but quickly fixed with permission of AudioPhonics support.

Build quality is rather decent especially from listening distance.

Remote control: great/logical layout. Yes it's light and a bit plasticy but it functions well. A more classy remote like the Apple Tv's aluminium remote would've been nicer at this price point.

Auto-on or Audio passthrough when the unit is switched off is not advertised or mentioned but it can be done. This unit seems a bit of a clone of the Douk VU3 and that one has powered-off passthrough:

Connect your main speakers @ Speaker 2 terminals and your main amp @ Amp B!

Then the VU meters..
Well, as mentioned everywhere: they're NOT sensitive, even at their maximum sensitivity. I am running quite sensitive Klipsch speakers and it's about 25 dB behind. So even with less sensitive speakers, I don't think you'd get a lot of swinging meters. They look nice though!

Trés sympa mais calibrage limité
Petit appareil tres bien fini, solide, design simple et propre.
L’idée etait de juste en tester un pour éventuellement en prendre 4 pour mon 4.1 haut rendement.
C’est surtout un watt metre et selon le systeme ça va swinguer plus ou moins.
Dans mon cas, oú en plus je ne cesse de réduire la puissance suite aux mesures de tensions en utilisations diverses, ben ça bougeait presque pas.

J’ai bien tenté de l’ouvrir pour voir si on pouvait le modifier pour étendre la plage de calibrage, mais c’est au dessus de mon niveau.
Du coup en fouillant un peu les interwebs, “Z review” proposait une bonne idée pour palier au calibrage trop limité : carrément lui dédier un ampli.
Cad ne brancher qu’un ampli supplémentaire en source, sans hps, une sorte de circuit parallele et plus facile á calibrer du coup, pour swinguer les aiguilles sans se péter les feuilles.

J’avais un canal libre sur mon master dsp donc facile, un ptit v3 qui trainait et hop on branche.
Ensuite réglages niveau dsp / volume ampli / calibrage lc30 pour atteindre un comportement plus vivant.
Au final c’est tres sympa, d’ou le long retour ici.
Ça bougeotte a peine pour les ecoutes tranquilles, ça swingue bien pour le pêchu, mais bien sûr ça sort du cadran pour le vraiment fort, pas grave c’est rare de toutes façons.

Selon Fosi l’ampli voit quand meme 390ohms, en tous cas il ne chauffe absolument pas, et consomme rien.
Le top serait le meme genre d’appareil mais branché en digital sur la source, sur le -0dbfs.
Un step de plus en 25% sur les leds serait pas mal aussi, voir choisir la couleur elle meme, ça je vais ptet le bricoler.
Aiguilles tres reactives, a chacun de juger moi ça me va.

Ha, et il est assez gros et vide pour y mettre une TPA, j’dis ça comme ça Audiophonics hein ;)
