The W2324 is a high-precision tool to solve phase problems in sound recording and playback applications. Comb-filtering is a common and usually undesirable effect caused by differences in phase when combining multiple signals from one source, such as a microphone and a DI signal from an electric guitar or multiple microphones on a kick drum. The W2324 phase shifter is the ultimate tool to hone in and correct those phase problems with unheard-of accuracy and sound quality. Alternatively, experienced engineers will appreciate the creative sound design possibilities offered by the module.
Furthermore, the W2324 can be used in the subwoofer path of any playback system to optimize the low-frequency response and remedy room mode issues thanks to the continuously adjustable phase angle.
Within the selectable frequency range of 23 Hz to 1.57 kHz any frequency build-ups or cancellations due to the time delay between multiple sources or (when used in the playback path) due to problematic room acoustics can be addressed by shifting of the phase. Simply select the desired frequency range with the 11-position rotary switch and correct the level and phase. A 3-position flip switch further allows phase angle extension from 190° to 305° as well as providing a bypass position for a quick and easy comparison with the uncorrected signal.
As all Roger Schult products, the W2324 is hand-crafted and precision-engineered in Germany.
