SPL Marc One

with innovative features and a 32-bit AD/DA converter. A monitor controller with which you can also record. And both in impressive sound quality.

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, synthesizer or an analog tape machine / tape deck can be connected to the analog line inputs.

32-bit AD/DA Converter
The converter chip used is the superior AK4490, which belongs to the new generation of premium 32-bit DACs and is equipped with AKM’s Velvet Sound®. This technology makes the finest details audible thanks to its low-distortion architecture. Sampling frequencies up to 768kHz PCM (16x CD resolution) are supported and DSD (Direct Stream Digital) playback is supported up to DSD4 or DSD256 (11.2 MHz) resolution.

Thus the Marc One qualifies for the currently highest resolution audio playback.

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 require the camera adapter. For Windows, a driver is required, which you can download at the bottom of this page.

Three Monitoring Modes
are offered by the Marc One. In the middle is the default setting “Stereo”. To check the mono compatibility set the switch to “Mono”. The special feature is the channel swap function:
