2Control: Monitor Controller – Introduction


Stereo Monitor Controller

The 2Control is an excellent sounding compact monitor controller that perfectly controls your near-field and full-range monitors. It is equipped with our crossfeed control for headphone monitoring to create mixes on phones that translate on speakers.2Control_R_RGB

Inputs & Speakers

The 2Control, which is analog throughout, allows the connection and selection of two stereo sources. These can be monitored via two stereo speaker sets and two headphones.

A third mono output is used to connect a subwoofer or mono loudspeaker.

The inputs are additive! The 2Control mixes the input signals together.

The volume is controlled by a high quality potentiometer (ALPS RK27 “Big Blue”) with active control and a 45mm full aluminium rotary knob.

The inputs are designed for balanced analog line-level signals. The input IN1 is calibrated to a nominal level of +4dBu.

The sensitivity of input IN2 can also be adjusted to a nominal level of -10dBV – ideal for connecting consumer level CD/DVD players.

Headphone outputs with Crossfeed

The 2 Control is equipped with two active output stages for headphones, whose level can be individually adjusted.

To be able to judge a mix via headphones, the super stereo effect, which affects the placement of voices and instruments in the stereo image and also reverb rooms and the generally exaggerated effects, must be corrected. This is done by the crossfeed control, thanks to which mixes created on headphones work just as well on speakers.

Crossfeed is a part of our Phonitor Matrix. In its largest expansion stage it has three adjustment parameters: Crossfeed, Speaker Angle and Center Level.

In the 2Control 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 crosstalk of the channels, the so-called interaural level difference. The intensity of the crossfeed is infinitely variable.
