Flexible Monitor Controller
The Marc One provides a three-position toggle switch letting choose between the two pairs of speakers or the option of muting the studio monitors completely without the need for turning the volume knob down, keeping your preferred settings untouched.
The monitor section comprises of many useful features. In addition to the large volume control, it includes three functions over a three-position toggle switch, letting you monitor your mix in Stereo or Mono. The third position reverses the stereo image by inverting Left and Right channels. a Monitor control lets you select between the analogue input source and USB and anything in between. This function lets you quickly adjust the levels between the two sources for critical listening.
The Marc One includes two analogue stereo input sources and one Digital USB to connect your DAW. It also includes a Line out allowing you to route your signal to additional headphone amplifiers or outboard and mixers for additional processing.
32-bit/768kHz AD/DA conversion
Using the latest AKM AK4490 32-bit DACs with Velvet sound, the Marc One converts any signal in all its glory, providing all the finest details with vanishingly low distortion. It provides sample rates of up to 768kHz PCM which is 16x CD resolution. furthermore, the Marc One supports playback of DSD (Direct Stream Digital) formats up to DSD4 and DSD256 resolutions.
The Class Compliant USB connection ensures that your Marc One works as an audio interface on all Mac computers and iOS devices without drivers. iOS users would require the camera adapter. Windows user can easily download the driver from the SPL website.
Powerful Headphone amp with Phonitor Matrix
In addition, the Marc One includes a powerful headphone amp capable of powering even the most hungry headphones. It uses a push-pull Class AB amplifier capable of generating a high gain. The use of bipolar transistors to share amplification of positive and negative half-waves ensures higher output levels than traditional Class A operation. Thermally-coupled output stage transistors also ensure coherent operation resulting in a consistent and stable stereo image.
It also uses a simplified version Phonitor Matrix technology with Crossfeed control found on their flagship headphone amps. By sending a slightly delayed signal to the other channel, it creates a phantom centre, just like when listening to speakers.
This technology allows for the most realistic listening experience on headphones by affecting three parameters: Crossfeed, Speaker Angle and Centre Level.
In this version, however, speaker angle and centre levels are already set to the most popular values (30¬∞ speaker angle, -1dB Centre level) leaving you to control the amount of desired crossfeed. The intensity if fully variable. When set to the minimum value, the crossfeed circuit is completely removed from the audio path using a hysteresis circuit relay.
