Speakers & Subwoofer
You can listen to your production via two switchable pairs of speakers. A subwoofer is also switched on and off with speaker pair A. In the middle position of the switch, the speakers are switched off, which is convenient because you don’t have to turn the volume control back.
Monitor
You can adjust the volume levels at lightning speed with the Monitor knob. In the middle, all input signals are equally loud. To the left, the analog stereo inputs get louder and the USB input signal gets quieter.
Turning from the center to the right does the opposite. So you can quickly and intuitively set the right volume levels.
Line Inputs & USB
Two analog stereo inputs and one digital USB input can be connected to the Marc One. The DAW (Digital Audio Workstation) is preferably connected via USB.
Other players like CD player, mixer, mic preamp, synthesizer or an analog tape machine / tape deck can be connected to the analog line inputs.
32-bit AD/DA Converter
The converter chipset is from AKM’s premium Velvet Sound® series. The AK5552 is used as the analog-to-digital converter and the AK4490 as the digital-to-analog converter.
Both the AD and DA converters offer 32-bit processing. The Velvet Sound® technology makes the finest details audible thanks to its low-distortion architecture.
Sampling frequencies up to 768 kHz PCM (16 times CD resolution) as well as the playback of DSD (via DoP – DSD over PCM) up to a resolution of DSD4 or DSD256 (11.2 MHz) are supported.
This qualifies the Marc One for the highest resolution audio recording and playback currently available.
The USB connection is Class Compliant. This means that all Mac computers and iOS devices like iPads and iPhones can use the full performance bandwidth of the AD/DA converter without driver installation. iOS devices need the Camera adapter.
For Windows, a driver is only needed if higher sample rates are desired. The driver is available for download at the bottom of this page.
Line Out
The Line Out carries the mix between the Line Inputs and USB playback and is controlled by the Monitor knob. The level is unity gain, thus independent of the volume control.
So the Marc One can be looped between devices without “losing” an output.
For example, if several people should listen in via headphones, headphone amplifiers can be connected to the Line Out. But you can also record the signal analog or send it to a mixer for further processing.
