Centrance Mixerface R4

The Centrance Mixerface combines a professional field recorder with an interface offering audio-grade sound quality in a pocket-sized format. The Mixerface R4 was named Best Newcomer Product in the Recording category at the 2018 NAMM Show and impresses with its sound quality and workmanship.

The R4 has 2 XLR/jack combo sockets for mic, line and instrument signals. The integrated instrument preamp is equipped with a Hi-Z circuit, allowing you to select the input impedance.

The A/D converters ensure outstanding audio quality – even on the go – and complement the Jasmine mic preamps, which can also be used with condenser microphones thanks to the 48V phantom power supply.

The Ampextreme headphone amplifier unit offers plenty of headroom and very detailed signal reproduction.

The R4 offers a stereo aux input, a line output (switchable stereo/mono), two USB ports, one for data transfer and one for charging the integrated lithium-polymer battery.

The mixer interface can be used with popular recording apps on smartphones or tablets and supports Android, iOS, Mac and Windows.

Test conclusion from Amazona (amazona.de/test-centrance-mixerface-r4-r4r-mobiles-audiointerface/):

‘The two brothers Centrance Mixerface R4 and R4R are both tiny, but sound amazingly good and are extremely versatile. They work well with any modern computer, smartphone and tablet, and the R4R model can also be operated completely independently as long as the battery is charged. Neither are exactly cheap, but they are worth the money.’
