The Empirical Labs ELDS-V DerrEsser is unlike other de-essers, the device allows for multiple use of its
powerful circuitry.
The Empirical Labs ELDS-V DerrEsser is 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 our 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,
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 EQ’ing
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. We 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.
As far as value, it’s hard to beat 500 Series compatible modules. Their
smaller physical size let you get a lot of performance out of a smaller
space, they tend to cost less than their larger counterparts, and – the
best part – you can customize your own combinations of them.
When ELI started making our own 500 series products, we looked at the
power supplies on the market and couldn’t help but notice a need for a
better single height dual module rack unit. On other single height rack
units, the modules protrude from the front panel, and don’t look sturdy
or attractive. Power supplies were often noisy, frequently reducing the
performance of any module mounted in them. Also, only XLR ins and outs
were provided to the user, limiting the device’s applications.
The Empirical Labs EL500 rack eliminates these obstacles. At the heart
of the unit is a super quiet power supply - over 30 dB quieter than some
supplies we’ve seen - that will ensure optimal performance from any
compatible device.
All 500 series modules will flush mount cleanly in the EL500, providing a
much more professional look and feel. The EL500 offers both XLR and
phone rear panel inputs and outputs to allow it to interface perfectly
with any system.
In addition, a ¼” instrument preamp/direct box input is provided on the
front panel, which will automatically switch the left 500 module’s input
to this front phone jack once something is plugged into it – a feature
we’re sure will prove to be extremely useful. In fact, it has become the
first call bass DI for many engineers. Switches to link compressors
and engage a 48V phantom supply are also provided.
Whether you’re already invested in 500 series modules or they’re
something you’re thinking about adding to your arsenal, the EL500 rack
will make any 500 series compatible module perform ideally and interface
effortlessly into just about any audio application.
