This complete analog channel strip performs six separate functions: microphone preamplification, de-essing (sibilance removal), compression/limiting, downward expansion, parametric EQ, and voice symmetry alignment. All six processes may be used simultaneously. Although we call the 528E a “Voice Processor”, it is perfectly suitable for any mic- or line-level source. Revered as the choice for broadcast voices and known as the classic “one channel console” by recording studios, the 528E delivers all the control you need, without the cost or complication of separate units. Each function has a full complement of controls in an easy-to-use layout. The 528E works with any professional microphone. Mic preamp gain is variable up to 60 dB, and 48 volt phantom power is provided for condenser mics. A switchable 15 dB pad reduces gain in front of the mic preamp to prevent distortion in super-close micing situations. A front panel switch selects between microphone or line input. Both inputs are transformerless and are equipped with filters to prevent radio frequency interference (RFI). The de-esser senses and regulates selectable high frequencies to reduce or eliminate annoying sibilance and “lip smacking.” Symetrix’ program-controlled Integrated Dynamics Processing (IDP) techniques combine the best attributes of compressor/limiters and downward expanders. The compressor/limiter maintains uniform levels while the downward expander eliminates “pumping,” “breathing,” and noise build up. Because it’s program controlled, the 528E’s dynamic range processor responds quickly to transients, and gently to smaller level changes. Separate LED meters display mic/input gain and gain reduction, for quick and accurate adjustment of dynamics functions. The three band parametric EQ performs both creative enhancement and corrective (eliminating resonances and interference) operations, with bandwidth variable from 0.3 octave to 4 octaves, 15 dB boost/cut, and overlapping frequency ranges. A unique “leap frog” topology minimizes the number of amplifiers in the signal path while ensuring that each frequency band interacts with its neighbor in a desirable and musical fashion. The Voice Symmetry switch corrects for excessive positive or negative signal peaks of the human voice.
