Description

Mercury is the first mastering DA-converter in 120V technology. It offers seven digital stereo input sources, all of which can be synchronized with each other or with a word clock. The additional variable output qualifies Mercury as a monitor controller.

Seven Digital Sources
Mercury provides connections for a total of seven digital stereo input sources. For each digital source there is a dedicated and illuminated tactile switch for quick selection and quick comparison. The detected sample rate is shown in the display. One USB input and two coaxial, two optical and two AES/EBU inputs are available. AES input 2 also supports Dual-Wire (DW) mode.

Sync
The display shows the synchronization status and the detected sampling rate. Any source except USB can be synchronized to another source or to an external Word Clock. If the sync "Source" is selected in the display, each source uses its own sync code embedded in the signal.

0 dBfs
Holding the Sync button for more than two seconds Mercury will change to the 0dBfs display. Mercury offers all reference levels in dBu corresponding to a 0 dBfs (full scale) digital signal: +14, +15, +16, +17, +18, +20, +22 and +24 dBu

Fix And Variable Outputs

Fixed
The FIX OUT is an analog balanced stereo output which can be calibrated to all common reference levels (see 0 dBfs). Mercury offers a variable analog balanced stereo output. This output provides the same signal as the FIX OUT, but the level is continuously adjustable. Thus Mercury can also be used as a state-of-the-art monitor controller.

Variable Output
This analog potentiometer is used to control the level of the VAR OUT output. We use the ALPS RK27 "Big Blue" potentiometer with a nice "spoon in honey" feel and excellent channel tracking. So not only the auditory but also the haptic experience of volume control is at the highest level.

The 120V technology
The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps.

The highest possible audio quality requires the highest possible audio operating voltage. The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.

The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.

By the way, the "120V" in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.

The mains voltage from the mains power socket is transformed to the required secondary voltage in the device's internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
