Speck Electronics EQF 810 4-Band Parametric Equalizer

Single-channel analog 4-band parametric equalizer and variable filters in a 1/2 rack format

Product Description

The Speck Electronics EQF 810 is an all-analog, single-channel 4-band parametric equalizer in compact half-rack format. Quickly add life to drums, bass, guitars, vocals and more using the intuitive interface. Use the convenient front-panel switch to choose between Jensen transformer-balanced and active-balanced outputs for a variety of tonal options to suit any situation.


The EQF 810 is equipped with four sweepable bands, providing coverage over the entire audible frequency spectrum—and then some. The L Band can be configured in shelf or peak mode, and covers the 20 Hz - 400 Hz range. Add up to 15 dB of gain for thundering low-end.

The L/M Band features a unique X10 button, providing coverage over the low-end (40 Hz - 800 Hz) or the midrange (400 Hz - 8 kHz). The L/M Band also features a variable Q control for fine-tuning your EQ shape—perfect for surgically removing the ring from a snare drum, or subtle shaping your drum bus.

The M Band is a fully parametric midband that covers the midrange from 400 Hz - 10 kHz, perfect for adding punch and clarity to vocals.

The H Band, like the L Band, can be configured in shelf or peak mode, and covers high frequencies from 1.5 kHz all the way up to 25 kHz, for a brilliant, shimmering top end.


The EQF 810 also features two variable filters, perfect for tightening up low-end and giving tracks the lo-fi treatment. Featuring a fixed slope of 12 dB per octave, the low-pass filter can be set as high as 25 kHz or as low as 150 Hz, perfect for taming harsh cymbals, sibilant singers, and bright acoustic instruments.

The high-pass filter also uses a 12 dB per octave slope, and covers frequencies from 100 Hz to 250 Hz. The high-pass filter also features a switchable X5 button, allowing you to roll-off the bottom-end all the way up to 1.2 kHz. When using the default setting, the high-pass filter is perfect for cleaning up kick and bass tracks, and the versatile X5 switch works wonders in certain situations, such as trying to remove kick bleed from cymbal mics.

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.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

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.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
