Excellent preamps
suhrawardi, 06.07.2020
This recorder is not like many others. It doesn't have a lot of features, and it's interface is very minimal as well.
But, it has really excellent low noise pre-amps! The sound quality is very good for it's price tag.
And it's very small.

I mainly use it for field recording with 2 mics which use phantom power. So I don't change the settings that often. I also don't change the input levels a lot. And although it doesn't have a meter to show the levels, it so far always worked out very well for me.

The battery does last me a few hours. But I don't like the fact that I cannot seem to change it's internal battery.

gute Preamps sind nicht alles
kalle09, 21.02.2020
Das Gute zuerst: die Preamps sind wirklich gut, so wie in vielen Kritiken geschrieben wird. Ich habe das MixerFace mit einem Focusrite Scarlett und einem Tascam Dr40 Recorder verglichen und kann sagen, dass es wirklich viel Pegel bei wenig Rauschen hat.

Die Verarbeitung wirkt sehr solide. Allerdings sind relativ viele Schalter so im Gehäuse versenkt, dass sie nicht von Hand bedient werden können. Dafür wird allen Ernstes eine Büroklammer zum Aufbiegen mitgeliefert. Das finde ich eines 450€ Interfaces eher unwürdig. Die oben liegenden Knöpfe funktionieren natürlich alle, aber eine Freude ist die Bedienung nicht, da das Feedback fehlt. Nächstes Manko bei den Features: Alle Audio Ausgänge sind Mini Klinken. Das mag für den Anschluß von Studiomonitoren noch funktionieren, aber falls man vor hat, ein paar Aufnahmen in einer Performance Situation live abzuspielen, dann braucht es noch ein anderes Interface, da Miniklinken für den Bühnenbetrieb meistens nicht passen. Na gut, es steht ja auch Recording Interface drauf und nicht Performance.
Nächste Schwachstelle: Der Akku ist ein fest verbauter. Über einen Austausch habe ich nichts gefunden, so dass ich mich frage, was man mit dem ganzen Gerät macht, wenn der Akku in ein paar Jahren aufgibt. Die wirkliche Arbeitszeit habe ich nicht getestet. Ich habe binnen einer Stunde die SD Karte formaiert, ein gutes Dutzend Aufnahmen von eingien Sekunden Länge gemacht und danach das Gerät zum Entnehmen der Speicherkarte an- und ausgeschaltet. Das hat 25% das Akkus verbraucht, sodass ich Zweifel habe, dass der Akku ein zweistündiges Konzert ohen Nachladen schafft. Warum keine austauschbaren AA Batterien? Damit wären wir beim nächsten Schwachpunkt: die USB Anschlüsse sind alle Micro USB. Für Outdoor Equipment hätte es etwas stabileres sein können. Ich werde sicher nicht mit Powerbank, Tablet und zwei Micro USB Kabeln zum Field Recording in die Wildnis aufbrechen.
Der ausschlaggebende Punkt, warum ich es zurück schicke ist jedoch, dass des Recording auf die SD Karte nur in Stereo bei 48.000 Hz Samplungrate möglich ist. Auf meine Frage, wie ich einen Mono Klang mit einem Mono Mikrofon im Monoformat aufnehmen kann, schrieb der Support, dass könne ich ja in der Postproduktion machen. Falls es technisch möglich ist, aber ich finde es sinnlos und hätte sicher leicht anders eingerichetet werden können. Der Webseite und den Tutorials nach ging es hier beim Entwickeln eher um Kameraton als um Fieldrecording oder Sounddesign. Mal ehrlich: braucht es gute Vorverstärker für eine Facebook Live Session? Interessant übrigens, dass es dann doch einen Schalter für Hi-Z gibt, damit Gitarre direkt aufgenommen werden kann - in Stereo...

Fazit: baut um die eigentich sehr guten Preamps bei Version 2 einfach oben und an der Seite 1 cm mehr Gehäuse dran, damit 6,3mm und USB A Stecker Platz haben, fügt schnelle Treiber hinzu, ersetzt den Akku durch ein Batteriefach und lasst den Benutzer beim Aufnehmen auf die SD Karte das Format selbst entscheiden. Dann habt ihr ein Interface was wirklich in ganz vielen Situationen einsetzbar ist kann und die 450€ sind völlig angemessen. So ist das Mixerface R4R ein Sammelsurium aus Kompromissen, die zumindest mir gar nichts nützen.
