Dynamic Sibilance Controller (with switchable mic/line inputs)
The Orban 536A Dynamic Sibilance Controller is an improved, two-channel version of our popular single-channel 526A (but without the mic input). The 526A and its ancestor, the 5I6EC, are considered to be the industry-standard de-essers and are found in professional audio facilities throughout the world. Now, with the introduction of the 536A, we offer the most cost-effective package available today-two channels of de- essing at an affordable price.
Like its predecessors, the 536A is designed to work effectively on voice only in its many professional applications. (Users requiring de-essing of mixed tracks should consider the Orban 422A/424A Gated Compressor/Limiter/ De-esser.)
Compared to its competitors, the 536A offers vastly simpler setup, im- proved noise and distortion performance, and no emphasis of residual IM distortion while de-essing is occur- ring.
The 536A is active-balanced at both inputs and outputs. For applications requiring a fully-floating output, optional output transformers can be fit- ted. Like all Orban products, the 536A features RF filtering of input, output, and power leads to help assure trouble-free installation in high RF fields.
The 536A is simplicity itself to operate. There is only one adjust- ment: a THRESHOLD control. The amount of sibilance energy is limited to a certain fraction of the non- sibilant speech energy-even if the input level changes as much as I SdB. The THRESHOLD control determines this fraction. Thus, a consistent balance between the “voiced” and
” sibilant” sections of speech is achiev- ed whether or not input levels are well-controlled. This is especially useful with off-mic voices, or in any application (such as motion picture sound) where speech levels vary widely.
A dual-LED display indicates the amount of de-essing which is occur- ring (“Normal” and “Heavy”), warn- ing of possible misadjustment of the THRESHOLD control. An peak- stretching OVERLOAD indicator warns of clipping anywhere in the circuit.
