The RME Digiface USB offers up to 32 channels of digital audio in stunning 192kHz via the four optical ADAT/SPDIF inputs. Expand your recording rig with simple plug-and-play technology for seamless integration to your setup. Included with the RME Digiface is the TotalMix software a comprehensive mixing and routing matrix that allows you to configure your inputs and outputs in any way that you need for your session including the ability to use several output sources simultaneously. Housed in a compact and portable shell the RME Digiface USB is USB-powered eliminating the need for any bulky power supplies making it the ideal solution for mobile producers and engineers looking for an expansive digital audio interface option. Compact portable and lightweight Audio Interface Ideal for expanding on your setup the RME Digiface USB features four optical ADAT/SPDIF I/Os resulting in additional 32-channel inputs and outputs for your recording system. Following the legacy of the HDSP Digiface the Digiface USB simplifies your workload with a simple USB 2 connection for plug and play compatibility as well as eliminating the need for external power supplies. A zero-latency headphone output via 6.3mm TRS Jack allows you to monitor back your recordings and levels in stunning fidelity. Take control over your recordings with TotalMix With RME Digiface USB you will gain instant access to the celebrated software TotalMix. This allows for practically unlimited mixing and routing operations with all inputs and outputs to create your own customised templates and sessions. as the RME Digiface USB does not have any integrated DSP there are no effects available within this version of TotalMix instead you have maximum control over how your sessions are organised and routed. With the powerful Control Room section you have access to Talkback channels mains/phones fader groups mute groups and much more all controllable remotely with Mackie or OSC protocol. The unique capability to create as many independent submixes as you need makes TotalMix every producer and engineers dream studio companion. With TotalMix you can set up to 17 delay-free submixes unlimited routing of inputs and outputs send your signal to several outputs simultaneously integrate external devices such as outboard effects simultaneous playback of different programs via a single stereo output and much more. However you need to set your session up with RME Digiface USB and TotalMix nothing is impossible! Test measure and analyse your signals with DIGICheck The secret weapon of high-resolution audio measurements DIGICheck allows you to meter test and measure digital audio streams in stunning resolution. Monitor all channels in your audio stream using Spectral Analysers Goniometers and even Bit Statistics to check your Peak RMS levels phase correlation dynamics signal to noise ratio and much more. Completely customisable you can choose what parameters to view and how they are displayed within your windows to best read the data.
