Description

SPL Marc One is a monitor controller that you can also use for recording. Both offer impressive sound quality.

You can listen to its output through two pairs of interchangeable speakers. The A speaker pair can also turn the subwoofer on and off. In the middle of the switch, the speaker is turned off, which is convenient because there is no need to turn the volume control back on.

The converter chip used is the superior AK4490, which belongs to a new generation of advanced 32-bit DACs and is equipped with AKM's VelvetSound®. With its low-distortion architecture, the technology can hear the finest details. It supports PCM sampling rates of up to 768 kHz (16x CD resolution) and supports DSD (Direct Stream Digital) playback up to DSD4 or DSD256 (11.2 MHz) resolution.

The USB connection fits into this category. This means that all Mac computers and iOS devices (such as iPad and iPhone) can use the full performance bandwidth of the AD/DA converter without installing drivers. iOS devices require a camera adapter. For Windows, a driver is required, which you can download at the bottom of this page.
