SPL - BIG Stereo Image Shaper

BiG

The Stereo Image Bigger Maker for 500 Series.

500 Series double-slot module for stereo stage processing.

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.

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)

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.

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 difference signal derived from the input signal is processed by an analog filter network before mixed back to the original signal in a special mixing stage. This is not M/S processing but a completely different and new way of stereo-processing. The processed stereo signal, when summed to mono, creates a clean mono signal without phase shifts, cancellations, or other unwanted artifacts.
