Good value for money
30.06.2014
Bought this amp for use in a small church. Works very well. used with a lapel mic for the priest. Easy to get the right levels for optimum performance. would recommend for anyone who's on a budget.

Works ok with 230 VAC, but not with 12 VDC input!
22.10.2014
Basically this amplifer does its job as supposed, but only when powering on 230 VAC. When running on 12 VDC (also tried with 14,4 VDC - lab psu) strange thing happen: if using mic on MIC1 (talkover function), when signal goes higher then certain level (around 2/3), amplifer shuts down and recovers after around 5 seconds. If you connect microphone to MIC2 (no talkover) it works normal!!! (that means, that power amplifer probably works fine, but not the logic for talkover, which somehow puts amplifer in some standby mode).

Talkover function is fixed on first microphone channel and works ok, but no parameters can be set (music/talk ratio, release speed ...).

However, for such money that's quite good amp to use with 230 VAC.

[EDIT]
Because using at 12 V is urgent for my application, I first tried to raise voltage on 12 V input up to 15 V, but didn't help. Then I used 5A adjustable DCDC stepup, set it to 21 VDC and connect it right after the bridge rectifier after transformer (on 230 VAC line). Additional 10000 uF capacitor was added as well. This way, amplifer can also work with 10 V input voltage.

Einfach und gut einsetzbar
Rentner Karl, 14.12.2012
Ich suchte ein Gerät für ELA-Beschallung kleiner Säle (Diskussionen, Vorträge) und gelegentlichem Freiluft-Einsatz (Ansprachen).

Beide Kriterien erfüllt das Gerät anstandslos. Der Klang ist völlig ok, die Lautstärke ebenso. Mikros gehen über 6,3er Klinke, AUX leider nur über Cinch.

Es gibt keine Pegelanzeige, aber offensichtlich hat der Vorverstärker genügend Spielraum. Hörbare Verzerrungen hab ich nicht zu Stande gebracht; trotzdem würde mich zumindest eine Clipping-Anzeige doch etwas beruhigen.

Da ist es gut, dass man z.B. einen Kompressor (Sharc) einschleifen kann, wenn auch nur über Cinch. Der präsentiert mir die Pegelanzeige.

Tyytyväinen asiakas
Ville P., 18.12.2013
Minusta laite toimi täysin moitteetomasti ja on käytössä nyt keskusradiovahvistimena äänikin on puhdas,eli sellaista keskusradio tasoa. Työn jälkikin oli siistiä ja viimeistellysti tehty. Eli minusta tässä ei ole valittamista. Suosittelen kaikille jotka tarvitsevat pieneen 100v kaiutin järjestelmään vahvistimen
