What's the difference between IL-19 & IL-99SS ? ...

What's the difference between IL-19 & IL-99SS ? Which one will be good to reduce passive electric guitar hum & ground noise . Also which hum eliminator will be good for active bass guitar ?
Asked by: Nabil
Hi Nabil. Essentially, there is a slight variation in the circuitry on the IL-19-SS model versus the standard IL-19, which our engineers did in order to make the unit more closely mimic the older, metal-barreled IL-19s that Sescom made back in the 80s and 90s. Both units currently utilize an ABS plastic housing, and when the change to that housing was made, some people found that it didn’t ground as well to the chassis of older racks and cabinets as the old metal ones did, and hence the IL-19-SS was created to combat that. I would suggest the standard IL-19 first, as that tends to work for most people and most situations and I don’t think the IL-19-SS would offer any particular advantage in an active bass situation. Thank you!

I just ordered this and it is not working. Trying to eliminate a hum on blue bottle condenser mic. When plugged in I get another frequency hum and no mic signal. Am I doing something wrong or is this thing defective?
Asked by: George
Being transformer-based, the Sescom IL-19 In-Line Audio Hum Eliminator inherently blocks the 48V phantom power that your condenser mic requires.

will this pass intercom voltage through it? I'm having serious hum when connecting an RTS 2w system to a clear-com 2w system
Asked by: Opeyemi
No, the IL-19 does not pass voltage with audio signal. I believe what you need to use is an intercom interface which is a system-to-system adapter designed to connect two intercom systems together and eliminate issues that create grounding and signal mismatch. Perhaps the Telex SSA324 2 Channel, 2-Wire to 4-Wire Intercom System Interface Converter with Call Signal (B&H # TESSA324) may work for you since it can be used to connect 2-wire systems to 2-wire systems. This item is special order and our details are limited so here is a link to the manufacturer's product info page which also provides links to the user manual and specs: I would also suggest that you contact tech support at RTS to be certain that the SSA324 is compatible with your RTS and Clear-Com systems. Just let them know which two systems you have so they can confirm. There is a "Contact" link on the upper right side of the RTS page that directs you to phone and live chat contacts. Please let us know if you need further assistance. You can reach B&H by phone at 800-606-6969 or through live chat on the website.

Just ordered one. It's not working on my condenser mic. When plugged in the low frequency hum is eliminated but a high frequency hum is created and the mic signal is gone. Is thing defective?
Asked by: George
Hi George. The IL-19 is transformer-based and inherently blocks phantom power, so assuming your condenser mic requires phantom power, the IL-19 will not work as it is blocking the power the mic needs.

Someone know how is this product wired ? Hot in pin 2 or 3 ?I work in Europe and I wonder if I can use this product without phase issue... Thanks !
Asked by: Anonymous
This product maintains phase: pin 1:1, pin 2:2, and pin 3:3, coupled through a special high end audio transformer that is of a proprietary design and has excellent frequency response.

Will this work with line level and mic level signals?
Asked by: Alvin
We have used it for line level issues only. The product description seems to only identify various line level runs. It seems that it could work for mic level considering line level is one volt more than mic level.
