<i><span style="font-size: 16px;">The Empirical Labs ELDS-V DerrEsser is </span></i></span><i>unlike other de-essers, the device allows for multiple use of its 
powerful circuitry.
</i><br /><br />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, 
<br /><br /><b>
DS MODE -</b> (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.
<br /><br /><b>
HF LIMIT -</b> (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.
<br /><br /><b>
HIGHPASS -</b> (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.
<br /><br /><b>
LOWPASS </b>- (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.
<br /><br />
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.
<br /><br />
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. 
<br /><br />
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.
<br /><br />
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. 
<br /><br />
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.
<br /><br />
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.
