SPL Marc One Monitoring and Recording Controller

Monitor and recording controller with innovative features including three monitoring modes and a 32-bit AD/DA converter

MFR# SPLMARC1

Product Description

The SPL Marc One Monitoring and Recording Controller is studio controller 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. For SPL sound-quality is always in the foreground. When it sounds good, we like to listen. To get such a sound, you need experience and technical finesse. SPL have incorporated both into the Series One.

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 768 kHz 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.

Line Out

The selected input signal is slaved through unchanged to the Line Out. So the Marc One can be looped between devices without “losing” an output. For example, if several people should listen in via headphones, headphone amplifiers can be connected to the Line Out. But you can also record the signal analog or send it to a mixer for further processing.

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:

L/R > R/L

reverses the stereo image. L/R becomes R/L. This is important and extremely time-saving when you are searching your sound library for samples in video dubbing that should match a scene with direction of movement. If the direction is not correct, you usually will have to import the sample into the DAW to swap channels before you can hear and judge if the sample with reversed direction fits to the picture. With the L/R > R/L function this is no longer necessary. You can now simply swap the direction of movement while pre-listening samples in the library.

The Headphone Power Amp

Poor sound over headphones? Not enough juice? Not here. Marc One delivers a rich headphone sound and it can get really loud.

The output stage of the headphone amplifier is designed as a push-pull amplifier in class AB mode. The bipolar transistors share the amplification of the positive and negative half-waves, which produces a higher gain and a higher output voltage than in Class A operation, where only one transistor amplifies both half-waves.

The output stage transistors are thermally coupled and thus run particularly coherently, which contributes to a consistent and stable sound image. The power supply has a buffer circuit with low source resistance, ensuring generous current reserves even when driving low-impedance headphones.

The Revolution

The revolution in the headphone amplifier is the Phonitor Matrix, with adjustable crossfeed, thanks to which you can create mixes with headphones that sound the same on speakers. The Phonitor Matrix in its largest expansion stage has three parameters: Crossfeed, Speaker Angle and Center Level.

In the Marc One, the center level is preset to -1 dB and the speaker angle to 30°. These are the most commonly used values. The crossfeed function determines the so-called interaural level difference. The intensity of the crossfeed is fully variable. At the beginning of the control path the crossfeed circuit is not in the audio path. Dialing the control in switches on the crossfeed circuit via relay (hysteresis circuit). The audio signal therefore does not pass through the crossfeed stage if this is not desired.

Best fit

If the active speakers or the power amplifier are very sensitive the playback may already be fairly loud when the Volume control is in the first third of its control range. By activating the -10 dB dip switch the output level is lowered to accommodate for a wider usable range of the Volume control. With the Rec 1+2 dip switch both line inputs are mixed together and can be recorded via USB.

Power Supply

Good sound always starts with the power supply. This is where you lay the foundation for the performance of the entire device. Although the Marc One only includes a 12 V plug-in power supply unit, the secondary power supply inside generates a voltage level of +/-17 Volts for the analog audio sections with which professional levels of up to +22.5 dB can be achieved!

An elaborate low-drop operating voltage regulation provides more “juice” and regulates cleanly even when maximum operating voltages are reached. The Marc One delivers full power when used with the included 1.5 A power supply. Only use the 12 V plug-in power supply unit within the scope of delivery. The ON-switch puts the Marc One into operation.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!
Matthew R.
I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!
Ryan F.
In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.
Martin C.
This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
