Important Security Information Please note and retain this information. Carefully read and follow all of the safety and operating instructions before you use the machine. Be doubly careful to follow all warnings and special safety instructions noted in this manual and on the unit. The following information refers to modules built into the RackPack frame. Connections: Only use the connections as described. Other connections can lead to health risks and equipment damage.
Important Security Information Lightning: Before thunderstorms or other severe weather, disconnect the machine from wall power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before any severe weather, disconnect ALL the power connections of other machines and antenna and phone/internet cables which may be interconnected so that no lightning damage or overload results from such secondary connections.
Hook Up Fitting A Module The fitting and/or exchange of modules should only be carried out by qualified persons. Please read the manual of the RackPack frame. It contains all information needed to fit a module as well as all safety and notes and warnings. If you don‘t have the manual at hand, you can download it like all SPL product manuals from our website http://www.spl.info.
Introduction Back in the 1990‘s, we developed an alternative way to process signals in order to reduce sibilance based on phase cancellation. Unlike traditional compression methods, this procedure is much more unobtrusive and simplifies control to one single parameter. SPL‘s De-Esser quickly became a standard reference among recording studios, broadcast stations and live sound engineers. The most commonly used technology to remove sibilance is based on compression.

Rear Panel/Connections The Dual-Band De-Esser is fitted with one XLR input and two XLR outputs for balanced operation. Pin-wiring of all XLR sockets: Pin 1 = GND, Pin 2 = hot (+), Pin 3 = cold (-) Discrete balancing stages for both in- and output provide high common mode rejection and are capable of driving long cables (depending on the capacity of the cables and the following input balancing stages).
Control Elements HI-BAND ON, LOW-BAND ON Use the HI-BAND ON button to turn the HIGH-S-REDUCTION on or off. Use the LOW-BAND ON button to turn the LOW-S-REDUCTION on or off. The buttons light up when engaged. You can use the two processing stages separately or jointly. They are connected in series as independent de-esser modules. The low-band de-esser is set first in the chain.
Control Elements HIGH S-REDUCTION Use the HIGH S-REDUCTION control to adjust the intensity of the sibilance reduction in the upper frequency range. The center frequency for sibilance recognition is set at 11.2 kHz with a 3 kHz bandwidth. Scale values for the filter are displayed in dB. The actual reduction values, i.e. after phase cancellation, are displayed in the upper SR LEDs. Thus, when the control is set to 3 dB, actual reduction might only be of around 1 dB.
Control Elements Signal-LED (SIG.) The SIG. LED indicates that an audio signal reaches the input with a level above -20 dB. This LED helps the operator especially in complex setups to determine immediately whether the Dual-Band De-Esser actually receives any signal. Overload-LED (OVL) The OVL LED indicates a potential internal overload. It begins indicating approximately 3 dB ahead of any expected overload to leave headroom for peak levels. Overloads must be avoided to exclude audible distortions.
