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.
Speaker & 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.
Two Stereo Inputs
Two analog stereo inputs can be connected to the Control One for sources such as a DA converter, CD player, mixing console, synthesizer or analog tape machine/tape deck, which can also be listened to mixed together (1+2).
Line Out
The selected input signal is output unchanged at the Line Out. This allows the Control One to be looped between devices without “losing” an output.
If, for example, several people are to listen in via headphones, a headphone amplifier can simply be connected to the Line Out. You can also record the signal analog or send it to a mixer for further processing.
Three Monitoring Modes
are offered by the Control 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 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 Power Amp
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.
