SPL 2Control – Stereo Monitor Controller

SPL 2Control Stereo Monitor Controller Overview:

The SPL 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.

High-quality active circuitry delivers impeccable sound quality

Many of the D/A converters in audio interfaces don’t provide analog level monitoring control, which necessitates varying your signal level at your converter outputs. This leads to a lowered bit depth in the monitoring signal, which can sometimes lead to a perceptible loss in audio quality. The SPL 2Control monitor controller utilizes a high-quality speaker volume potentiometer and active circuitry, resulting in pristine sound. In contrast to passive circuits, the 2Control’s active design does not influence impedances when levels change, which can affect your frequency response. The 2Control’s active design guarantees linearity.

Crossfeed control provides incredibly accurate headphone monitoring

With the SPL 2Control monitor controller’s Crossfeed control you can adjust the stereo width of your headphones, imbuing them with the sound of a traditional monitoring environment, rather than the tightly focused and exaggerated stereo separation that you usually get from headphones. Imagine being able to enjoy a late night session at home without disturbing your neighbors and being able to monitor unhindered by a less-than-ideal acoustic environment. The 2Control gives you the benefits of headphone monitoring without its disadvantages. Talk about win/win!

High-grade balancing stages let you connect just about anything

The SPL 2Control monitor controller’s first-class balancing stages let you easily connect unbalanced gear without a direct box. For example, you can connect CD players with RCA outputs or hi-fi power amplifiers with RCA inputs (of course, you need properly configured cables to do this). You also get balanced outputs for two stereo speaker sets, as well as a single output for a mono speaker or subwoofer. You can effortlessly integrate the 2Control into nearly any audio environment.

Inputs & Speakers

The SPL 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 SPL 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.
