Fredenstein F610 UE1 500 Series Stereo 4-Band Parametric Equalizer

Touch screen enabled, digitally controlled stereo analog quad-band equalizer and dual channel 30 band real time analyzer (RTA) in a double wide 500 series module
MFR# F610

Product Description

The Fredenstein F610 Universal Entzerrer UE-1 is a digital controlled stereo analog quad band equalizer and 30 band spectrum analyzer in a double wide 500 series module.

For the first time in a 500 series module, we were able to implement a high resolution 3.5” LCD color display including a capacitive touch controller, thus welcoming the 500 Series to the 21st century. The four filters are all identical and each can be tuned from 20 Hz to 20 kHz. The encoder rotary frequency knob allows access to about 190 different frequencies per filter, while the USB interface allows for 1 Hz frequency resolution. The maximum filter gain is ±16 dB. In case more gain is needed, additional filters can be set at the same frequency for a ridiculous up to 64 dB boost or cut. The Q-factor of each filter can be varied from 0.4 to 7.9. The gain can be adjusted from -16 dB to +16 dB in 0.25 dB steps, clearly fulfilling the demands of modern sophisticated mastering. The Filter 1 characteristic can be changed from band-pass to low-shelf and Filter 4 to high-shelf.

In addition, a variable 2nd order low-cut filter with a range from 20 Hz to 975 Hz is provided as well as a “Color” function giving a tube-like sound. The hard bypass allows for quick evaluation of the EQed results.

The 30-band spectrum analyzer features a 60 dB dynamic range with select-able sensitivity from +6 dBu to + 24 dBu in 6 dB steps. The choice to feed either the input or the output signal to the analyzer adds to the versatility of the F610. Up to 99 complete settings can be stored in the internal non-volatile memory and a Micro-USB interface provides complete control from a connected host computer via RS232 over USB.

The F610 UE-1 name is an homage to the classic K&H UE-100. “Entzerrer” is the German technical term for equalizer.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
