The DerrEsser ELDS-V from Empirical Labs is a vertical multi-function dynamic filtering device, designed for API 500-Series enclosures. In its basic DS mode, it is an effective, level-insensitive de-esser, a device that will adjust the high-frequency gain on overly treble-y or spiky vocals or other sources in an extremely musical manner. However, unlike other de-essers, the device allows for multiple uses of its circuitry. 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. It features VCA technology for glitch-free, distortion-free, and noise-free performance. The corner frequency is user adjustable with a high-performance active crossover.

In HF Limit 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. In high-pass mode and while using the LISTEN function, the user can employ the 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 with the frequency knob. In low-pass mode and 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 with the frequency knob.

Related Questions and Answers

Q: 1. this can will work with 5d mark iii ?

A: No.this is for sony fs7 and other sony cameras, For the 5d3 you preferably want a compact flash card or else an SD card

Q: 2. is this 1:4 used for film?

A: Yes, this Kodak Professional Fixer can be used for black and white film development at a 1:3 dilution.

Q: 3. How long will the fixer solution in he gallon bottle last before it becomes unusable if I open it once?

A: I've had it work after more than a year after the first opening. I don't discard if sediment forms. I use it, but test clear time with a bit of unprocessed film. If film clears, paper will, too. (A clear time with fresh fix is noted and subsequent clear times compared.) This fix performs better than advertised. Hope this helps.

Q: 4. Will my standard compact flash card reader work with the XQD memory card?

A: No it won't. Only XQD card reader can read this card properly

Q: 5. After mixing the concentrate with water. What is the maximum time to be able to reuse it again?

A: The maximum time will depend on how this is stored and if it is being replenished. Properly replenished ILFORD RAPID FIXER in regular use should have a very long life but as a general guide it is advisable to replace it after 12 months in the processing tank. Unreplenished ILFORD RAPID FIXER working strength solutions should last for up to: 6 months in full tightly capped bottles. 2 months in a tank or dish/tray with a floating lid. 1 month in a half full tightly capped bottle. 7 days in an open dish/tray. More details can be found on the Technical Data Sheet linked here. https://www.ilfordphoto.com/amfile/file/download/file/1833/product/711/

Q: 6. Has anyone tested the 128GB version of this card in a Nikon D4?

A: I've used this 128Gb card in my Nikon D4 for over 100,000 RAW and JPG images. I've never had a single problem with the card.

Q: 7. Can I reuse the fixer for processing film?

A: Yes you can reuse it but it is recommended to replenish it. The instructions on that is on page 3 at this link, https://bit.ly/3MdKFI1 .

Q: 8. Any idea of how many 35mm 36x rolls this would last? Thanks.

A: As per Ilford, 24 rolls of 35mm film in 36 exposures can be processed at a 1+4 dilution

Q: 9. Will this card work with Nikon D 500

A: Yes this card works perfectly with my D500.

Q: 10. Can this card be used with the QDA-EX1 (ExpressCard) Media Adaptor to record 50mbps UDF to PMW-200?

A: Yes it will work! I have the exact combo and am using it right now.
