SPL Marc One
The monitor and recording controller SPL Marc One shines with innovative features and a 32-bit AD / DA converter. Thanks to its various connection options and its three monitoring modes, Marc One is extremely flexible and achieves impressive sound quality even at maximum voltages. The Phonitor Matrix allows you to create mixes through headphones that sound exactly as if they were mixed through Speakers.
important characteristics
• Two switchable speaker pairs, speaker pair A with subwoofer
• Two analog stereo sources and one digital source can be connected
• Monitor controls: analog stereo inputs / USB input signal
• 32-bit AD / DA converter (Premium AK4490 converter chip, Class Compliant): sampling frequencies up to 768 kHz PCM
• Line out
• Three monitoring modes: stereo, mono and channel swap function
• Thermally coupled output stage transistors
• Phonitor Matrix: Crossfeed, Speaker Angle and Center Level
• -10 dB dip switch: larger usable range of the volume control
• Levels of up to +22.5 dB can be achieved
