SPL Control One, Control One

The Monitor Controller

with innovative features, developed for fast workflow and impressive sound quality.

Play Video

Monitoring in highest sound quality.
Create perfect mixes on speakers and also on headphones – thanks to the Phonitor Matrix.

NUMBER ONE IN SOUND

For us the sound is always in the foreground. When it sounds good, we like to listen. To get such a sound, you need experience and technical finesse. We have incorporated both into the Series One.

“The SPL Control One is very well suited for smaller studio setups or post-productions where a simple, analog monitor controller is needed. Despite its flat format and basic features, it offers a classy sound that should normally only be expected from more expensive devices.”

Full control

The big analog volume control offers the perfect control range to adjust the monitoring volume intuitively and precisely.

Speaker & Subwoofer – monitoring without any compromises

 

As a full-fledged monitor controller, Control One offers two pairs of outputs for stereo speakers.
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.

Two stereo inputs

Control One provides two analog stereo inputs for input devices such as DA converters, CD players, microphone preamps, synthesizers or an analog tape machine.

 

“Considering the high sound quality and a level of manufacturing that deserves the label ‘Made in Germany’, the price asked is more than justified. Well done, SPL!” 

Sound & Recording

Line Out

The signal selected in the input section is output unchanged at the line output “Line Out”.

The line output has unity gain, the normal, unregulated output level – independent of the volume control.

Multiple users can listen in via additional headphone amplifier connected to the Line Out.

The Control One can also be easily looped into a monitoring chain without the need for another output at the playback source.

You can also send the signal to another mixer for further processing.

There are no limits to creativity here.

Perfectly monitored

Control One allows three different monitoring modes.
The mix can be monitored in “Stereo” or mono compatibility can be checked in “Mono”.

A special feature is the channel swap function:

L/R > R/L

This function reverses the stereo image. Left becomes right and right becomes left.

This is especially 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 have to load the sample into the DAW to switch channels before you can hear if the sample fits. With the L/R > R/L function this is no longer necessary. You can now simply swap the direction of movement while prelistening samples in the library.

The headphone output stage

Weak sound on headphones?
Not enough power?

Not here. Control One delivers a full headphone sound – and that up to 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 operating low-impedance headphones.

“Plug it in, let’s go – the analog operation of Control One and Marc One is superbly implemented and the sound is on the highest level. Studio technology for your home! The uncomplicated use in combination with the USB interface makes the Marc One in particular the perfect companion for high-quality audio enjoyment without having to rob the bank.”

The revolution in the headphone amplifier: Phonitor Matrix

The Phonitor Matrix enables mixing and mastering engineers to create perfect mixes on headphones, which will translate perfectly to all types of stereo speaker systems.

With Phonitor Matrix you can create 
perfect mixes on headphones.

But the Phonitor Matrix is not only designed for professional use in the studio. 
It also enables the hifi enthusiast to enjoy music on headphones, like if it was played back on speakers.

Crossfeed

Listenfing on headphones is different from listening on loudspeakers.

The biggest difference is the lack of crossing signals from the left speaker to the right ear and from the right speaker to the left ear.

Conventional

This results in an unnaturally wide and wrong stereo image.
The various sound sources of the audio signal are not localized as the sound engineer intended them to.

Correct

The SPL Phonitor Matrix will correct this false stereo image with ab analog circuitry and ensures a correct representation of the stereo image and a relaxed listening experience.

How is this possible?

Music is normally produced and mixed for playback on stereo speakers.

Listening on headphones is different from listening on loudspeakers. The biggest difference is the lack of crossing signals of the sound signal from the left speaker to the right ear and from the right speaker to the left ear.


These crossing signals are missing in conventional headphone listening, because there are no signals crossing from one side of the headphones to the other. This results in an unnaturally wide stereo stage and sound sources are not played back at their correct position in the stereo spectrum.

The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry.

The Phonitor Matrix parameters

The two main parameters of the Phonitor Matrix are Crossfeed and Angle:

• Crossfeed determines the crossing signals of the channels.
• Angle determines the opening angle of the stereo image.

The “Crossfeed” parameter of the Control One is continuously adjustable via the crossfeed control.
The “Angle” parameter is fixed at the studio standard of 30°.

To perfect the listening experience, the level of the sound sources centered in the stereo image must be attenuated when the Phonitor Matrix is activated. The result is that not only the position of all sound sources is correctly located, but also their volume.

For the Control One, this parameter, which we call “Center” for the Phonitor Matrix, is fixed at a -1 dB cut, which is the best choice for an authentic representation of the soundstage.

During conventional listening on headphones, our brain can compensate a certain level of false playback representation – but this is very exhausting and leads to listening fatigue.

Summed up:

The SPL Phonitor Matrix corrects the false representation of the stereo sound image, which makes it much easier to find the right decisions for mixing and mastering engineers. The hifi enthusiast can experience the music, like it was originally mixed and recorded.

So nothing stands in the way of a successful and long mixing session on headphones.

EVERYTHING YOU NEED TO HEAR ABOUT THE PHONITOR MATRIX

 

At a regular listening volume, the volume control should be in the one o’clock position. This gives you an ideal control range for listening quieter and louder.

If active loudspeakers or power amplifiers are very sensitive, the playback can already be quite loud when the volume control is in the first third of its control range.

Activating the -10 dB DIP switch attenuates the output level to allow a wider usable range of the volume control.

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 we “only” supply 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 the maximum operation voltage is reached.

The Control One delivers full power when used with the included 1.5 A power supply.

Just switch it on and enjoy the great sound. The ON-switch puts the Control One into operation.
