SPL BiG - Stereo Image Enhancer 500 Series Module

BiG is special. BiG is unique. BiG enlarges the stereo image in a new manner and opens up new creative ways of sound shaping. Intuitive with just three controls.

Stereo Image Shaping

Range
With the Range control, the frequency Range which should be processed can be selected.

Stage
With the Stage control, the frequency range previously selected with the Range control can be moved backwards or forwards on the stereo stage.

BIGNESS
The huge BIGNESS control adjusts the intensity of the STEREO IMAGE SHAPING.

On/Bypass
The On/Bypass switch activates (On) or deactivates (Bypass) the module. This allows you to quickly switch between processed and unprocessed signal.

Signal LEDs
The signal LEDs (Sig) indicate whether an audio signal is present at the input of the respective channel. (With a level higher than -20 dBu)

BASS
The BASS/Off switch can be used to activate (BASS) or deactivate (Off) an additional bass boost following the BIGNESS section. The bass boost is performed by a passive filter implemented in a similar circuit to the one used in the AirBass function of the SPL IRON Mastering Compressor.

Black magic?
In BiG, a mono signal derived from the input signal, which no longer contains any signal components in phase opposition, is processed by an analog filter network and mixed with the original signal in a special mixing stage.

The processed stereo signal, when summed to mono, creates a clean mono signal without phase shifts, cancellations, or other unwanted artifacts.
