Solides Metallgehäuse. Display und Menü ist für den Zweck OK. Der Drehregler ist gerastet, schwergängig und etwas klein. Längere Einstellungen möchte darüber man nicht unbedingt vornehmen. Für die Anzeige und Auswahl der Presets, Infosanzeige und Monitoring der Pegel aber völlig ausreichend. Lüfter sind leider etwas laut und laufen permanent, was eine Heimanwendung einschränkt. Die zu erwartende Wärmeentwicklung auch im Ruhezustand lässt sich im Owners Manuel im Kapitel "Power consumption and heat" erahnen. Worüber sich der Hersteller im Manual ausschweigt - wie in einer anderen Rezension schon geschrieben wurde, ist die Programmierung bzw. Zugänglichkeit der DSP Funktionen. Das ist aus meiner Sicht aber der beste Teil des Verstärkers. Es ist ein Chipset - mit DSP der Firma Digisynthetic verbaut, welcher auch die AES67/Ravenna und DSP Funktionalität mit sich bringt. Man benötigt allerdings die entsprechende Software - "Digisyn Link". Digisynthetic stellt diese auf Github zur freien Verfügung: https://github.com/Digisynthetic/Digisyn-Link-GUI Zur Programmierung muss der Verstärker dann über einen der RJ45 Ports an das lokale Netzwerk angeschlossen werden. Die SW findet den Verstärker eigentlich automatisch. Es lässt sich aber die IP Adresse über das Menü am Verstärker unter Infos abrufen. Praktisch ist, dass man über den 2. RJ45 Port einen weitern Verstärker in das Netzwerk durchschleifen kann -Dasiy Chain! Beschreibung der Software - Digisyn Link findet man auf Github. Über Digisyn Link lässt sich die volle DSP Funktionalität steuern. Klanglich ist alles im Rahmen des erwartbaren. Leises Grundrauschen auf den Ausgängen ist vohanden. Für High End Hifi aber auch nicht gedacht. Wer mit den oben genannten Einschränkungen (Lüfter, Bedienung am Gerät) kein Problem hat bzw. sich zu helfen weiß, bekommt in anbetracht der DSP und Netzwerkfunktionalität (AES67) echt viel für den Preis geboten. Ich bin sehr zufrieden und würde den Verstärker wie kaufen.

Solid metal housing. Display and menu are OK for the purpose. The rotary control is detented, stiff and somewhat small. You don't necessarily want to make longer settings. However, it is perfectly adequate for displaying and selecting presets, displaying information and monitoring levels. Unfortunately, the fans are a little loud and run constantly, which limits home use. The expected heat development even in idle mode can be guessed at in the "Power consumption and heat" section of the owner's manual. What the manufacturer is silent about in the manual - as has already been written in another review - is the programming and accessibility of the DSP functions. In my opinion, however, this is the best part of the amplifier. It is equipped with a chipset - with DSP from Digisynthetic, which also has AES67/Ravenna and DSP functionality. However, you need the corresponding software - "Digisyn Link". Digisynthetic makes this freely available on Github: https://github.com/Digisynthetic/Digisyn-Link-GUI The amplifier must then be connected to the local network via one of the RJ45 ports for programming. The software actually finds the amplifier automatically. However, the IP address can be called up via the menu on the amplifier under Info. A practical feature is that you can loop another amplifier through to the network via the 2nd RJ45 port - Dasiy Chain! Description of the software - Digisyn Link can be found on Github. The full DSP functionality can be controlled via Digisyn Link. In terms of sound, everything is within the expected range. There is a slight background noise on the outputs. If you don't have a problem with the above-mentioned limitations (fan, operation on the device) or know how to help yourself, you really get a lot for the price considering the DSP and network functionality (AES67). I am very satisfied and would buy the amplifier again.

Pojačalo sam kupio za pogon dva 15" bas bina u bridge konfiguraciji, ili za pogon dva 12" bas bina i dva topa kad nije potrebna veća snaga. Nisam ga još isprobao na punoj snazi, ali na manjim snagama je sve bilo u redu i pojačalo je dobro pogonilo zvučnike. Pojačalo nije za kućno slušanje - zvuk ventilatora za hlađenje je tada dosta čujan. Na žalost ono najzanimljivije, dsp modul za obradu zvuka kojeg proizvođač spominje nisam uspio upogoniti. Jednostavno u manualu nije navedeno kako se dolazi do naprednih dsp postavki. Podrška od strane proizvođača je nikakva - pokušaj kontaktiranja proizvođača nije uspio, također na stranicama proizvođača se ne može naći nikakva uputa ni softver za dsp u pojačalu. Tako da sam morao koristiti vanjski dsp modul. Šteta, jer sam pojačalo kupio upravo radi ugrađenog dsp-a, kad bi ovo riješili dao bih veću ocjenu.

I bought the amplifier to drive two 15" bass stages in a bridge configuration, or to drive two 12" bass stages and two tops when more power is not needed. I haven't tried it at full power yet, but at lower power everything was fine and the amp drove the speakers well. The amplifier is not for home listening - the sound of the cooling fan is then quite audible. Unfortunately, the most interesting thing, the dsp module for sound processing mentioned by the manufacturer, I was not able to start. It is simply not stated in the manual how to get to the advanced dsp settings. There is no support from the manufacturer - an attempt to contact the manufacturer failed, also on the manufacturer's website no instructions or software for dsp in the amplifier can be found. So I had to use an external dsp module. It's a pity, because I bought the amplifier precisely because of the built-in dsp, if they would solve this, I would give a higher rating.
