The Stereo Image Bigger Maker in 19" rack format. BiG Studio spectacularly enlarges the stereo image and opens up new creative ways of sound shaping. BiG [Studio] expands the possibilities of sound shaping with a new tube circuit. The Tube Harmonics control refines the harmonic spectrum of every signal, making it more vivid, detailed and increased in size - bigger than life! Visually, BiG [Studio] sports the black design of the SPL Studio series. The internal audio voltage of +/-18V ensures great sound! With the Range control, the frequency range which should be processed can be selected. With the Stage control, the frequency range previously selected with the Range control can be moved backwards or forwards on the stereo stage. The Bigness control adjusts the intensity of the stereo image shaping. In BiG Studio a difference signal derived from the input signal is processed by an analogue filter network before mixed back to the original signal in a special mixing stage. This is not only simple 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. The Tube Harmonics control adjusts the intensity of the harmonics generated in the tube. When the Harmonics switch is activated, the tube circuit which generates harmonics is in the signal path. If this switch flashes, the device is in "warm-up" mode. The tubes are being brought to the optimum operating temperature. The bass switch can be used to activate an additional bass boostat the end of the BiG [Studio] processing chain. The bass boost is performed by a filter similar to the one used in the AirBass function of the SPL IRON Mastering Compressor.
