Speaker & Headphone Monitoring Controller


The 2Control with its unique Crossfeed control allows to judge a stereo panorama on headphones just like with loudspeakers. The unit's concept is consequently based upon duality: Two channels, two sources, two loudspeaker sets, two headphones—2Control.


The speakers and headphones monitoring center

The 2Control combines loudspeaker and headphone monitoring in a compact, user-friendly and high quality control device. Control near-field monitors, full-range speakers and headphone monitoring for two listeners from one central unit!


Analog volume control for your DAW

A majority of D/A converters and sound cards provide nothing in the way of analog level monitoring control, and this means the necessity of varying signal levels at the converter outputs. The result is a lowered bit rate in the monitoring signal, which can lead to commensurate loss of audio quality. 


Two excellent headphone amplifiers

Friends, colleagues, customers: in the end there’s always someone else who wants to listen in, too. With the 2Control you also have the second headphone under control – and can rely on first-class quality.


Crossfeed control

With it's innovative crossfeed control, the 2Control allows to adjust the stereo width on headphones. Now headphone monitoring can be compared to speaker monitoring, making it possible to also mix on headphones. 

Some exemplary benefits of the crossfeed control: at home, nocturnal engineers now have an alternative to full range monitors for judging stereo imaging in their mixes. Furthermore, the headphone monitoring is not restricted for analytical listening only, but can serve as full stereo monitoring alternative. And the compact housing makes it easy to transport the 2Control to have familiar monitoring conditions at foreign places.


High-grade balancing stages

We use custom made balancing stages to drive long distances reliably and for first class common mode rejection values. Note that only balanced connections exclude hum and interferences. We recommend to establish balanced connections wherever possible – especially connections over long distances (e. g. to speakers).


Separate mono speaker output

In addition to two stereo speaker sets you can also connect a mono speaker or a subwoofer. Tip for working with headphones: Listen with subwoofer to enjoy the physical impact of the low end.

After bypassing my mixer and setting up the SPL to handle my monitoring, I was shocked at the difference in clarity and "vibe"

The 2Control illustrates the flaws of monitoring through mid-class mixers -or worse, directly out of your DAW. As SPL point out, if you monitor directly from your DAW to your speakers, using software to control your volume can lower bit-rate at the converter outputs, thereby degrading the audio quality. So, if you're wondering why your mixes sound like shit, it might be because everything you've been listening to sounds like shit. They say the best piece of gear we've got is our ears. Maybe we should invest in that.
