The Roland Rubix44 is a high-resolution audio interface that perfectly balances high-fidelity sound with a robust construction, compact size, and an affordable price, all crucial features designed for the modern musician and DJ/producer. The Rubix44 comes with support for 24-bit/192kHz audio which offers a crystal clear, highly-detailed sound and has been carefully designed to give you incredibly low noise from the input to the output while the universal USB support allows the interface to work seamlessly alongside Mac and PCs as well as iPads, which makes the Rubix44 the ultimate portable music production and performance audio interface. This interface is perfect for any DJ/producer or musician looking for a decent solution for recording directly into your digital audio workstation with high-quality audio.

Rubix-44 Overview

The Rubix-44 is equipped with four combo XLR/¼-inch TRS Jack inputs with four microphone pre-amplifiers which have been designed for low-noise and high-definition offering a clean, transparent sound with plenty of headroom which lets you capture all the subtle nuances and details of whatever you’re recording. The versatile combo inputs enable you to record a wide range of audio sources without the need for special adapters or cables. Four separate outputs mean you can make use of sophisticated routing options and monitoring setup, perfect for sending a click track to a performer, routing sounds to external equipment, or setting up an on-stage monitor.There isn’t anything that is more important than sound quality when it comes to audio interfaces, and you shouldn’t need to sacrifice sound-quality to have a wallet-friendly interface that you can take anywhere with you. The Rubix44 features a clean and highly-detailed sound with acoustically transparent low-noise microphone pre-amplifiers and can support 24-bit/192kHz audio resolutions. The durable build-quality and compact low-noise design with extensive shielding and ground lifts allow you to get excellent crystal clear audio wherever you take it.

For taking control of highly dynamic audio sources such as vocalists and percussion instruments this interface is fitted with dynamic processors that work to ensure a decent signal without clipping or causing unwanted distortion. The integrated compressor/limiter gives you peace of mind when recording in the heat of the moment. You are also given +48v phantom power so you can utilise the power of condenser microphones and direct injection boxes into your recordings while the Hi-Z function allows you to record guitars and other high-impedance sources with ease.

Stages and studios can be dark places, and it’s hard to focus on the performance you’re trying to record when you can’t get a decent input level because your clip and level indicators are too small and hard to see from across the room. Thanks to the highly visible clip indicators, which are an integral part of the design, this problem is a thing of the past and lets you clearly see when an incoming signal is overloading, even from across a darkly lit room.

The Rubix 44 is super-compact and ultra-versatile and features low-latency class-compliant drivers for both PC, Mac and even iPad, making it super-simple to get set up and run a session with a smooth and reliable audio performance. With plenty of audio inputs and outputs, this interface allows you to grow your setup without needing to upgrade your audio interface and is supplied with a copy of Ableton Live Lite a powerful Digital Audio Workstation and live performance application that works seamlessly alongside the Rubix 44 straight out of the box.
