500 Series Dynamic High Frequency Fixer
The first entry by ELI into the 500 series format, the DerrEsser is a multi function dynamic filtering device. Available in vertical or horizontal versions. A perfect fit for the EL500 powered rack. In its basic "DS" mode, it is an effective, level insensitive "De-Esser" - a device that will adjust the high frequency gain on overly trebly or spiky vocals or other sources in an extremely musical manner. However, unlike other De-Essers, the device allows for multiple use of its powerful circuitry.

The DerrEsser has four modes:
DS MODE - (Bypass Button IN, all other buttons OUT). As a De-Esser in the DS mode (HF Limit OFF), the threshold can be set to tame harsh S`s (sibilants) that result from an overly bright singer or from EQing to make a vocal sound aggressive and clear. The DS threshold is not level dependant, and compares the amount of high frequency content to the low frequency content, so adjusting the overall level does NOT affect the threshold. Easy to set and forget. Great care was taken to ensure this DS section meets the Empirical Labs reputation for originality and ease of use. ELI use the latest technology VCA, specially selected for glitch free, distortion free, and noise free performance. The time constants were carefully selected and the corner frequency is user adjustable with a high performance active crossover.

HF LIMIT - (Bypass Button IN, HF LIM IN, all other buttons OUT). In this mode, the DerrEsser essentially acts as a high frequency compressor. If there is enough high frequency content to exceed the threshold, then gain reduction occurs. It IS level sensitive, but responds much more to high frequencies. This mode is more of a general high frequency smoothing device, and is probably the first carefully tailored soft knee HF limiter in existence.

HIGHPASS - (Bypass Button IN, Listen IN, HP/LP OUT, HF LIM doesn`t matter). By using the "LISTEN" Function, the user can employ the superb filter circuitry inside the DerrEsser to process their audio. With the LISTEN button IN, and the HP/LP switch OUT, the user will be hearing the high frequencies that are being controlled with the dynamic/compression circuits. The corner frequency is adjustable by the Frequency knob.

LOWPASS - (Bypass Button IN, Listen IN, HP/LP IN, HF LIM doesn`t matter). With the LISTEN button IN, and the HP/LP button IN, the user is now listening to the low frequencies, those not affected by the VCA and dynamic/compression circuits. This is a 12 dB per octave filter whose corner frequency can again be adjusted by the Frequency knob.
