SSL 611EQ 500 Series Equalizer Module

The legendary SSL E-Series channel EQ packaged for your 500 Series rack
MFR# 729720X1

Product Description

Capture the iconic sound of the legendary SSL E-Series channel EQ right in your 500-series rack with the SSL 611EQ. A near-identical recreation of the classic Solid State Logic SL 4000 E console channel strip design, the SSL 611EQ combines the beloved four-band design with a versatile Black/Brown switch for two totally different response curves.


The SL 4000 E console has been used to mix countless classic records. Renowned for its punchy, grungy sound, the E-series channel strip is one of the most beloved EQ designs ever created. Now with the new SSL 611EQ, you can capture the sound of the original “Brown knob” design from the early 80s as well as the updated “Black knob” design from the mid to late 80s in one flexible 500-series package.

All SSL consoles prior to the summer of 1985 were equipped with “Brown-02” card, which offer a cut/boost of +/-15dB. The last version of the standard E series EQ is the ‘Black-242’ card, which features a cut/boost of +/-18dB. Both models feature unique frequency response curves, giving you two totally different tonal options a single module.


The SSL 611EQ features a four-band design, providing plenty of flexibility for tone shaping. Both the high and low frequency bands can be toggled from shelf to bell, allowing for broad adjustments or surgical precision. The midrange bands are fully parametric with controls for gain, frequency and Q allowing for diverse tone sculpting options. The BLK button toggles between the Brown and Black EQ circuits, while the IN button provides an easily accessible bypass button for A/Bing tracks.


The low-frequency band on the SSL 611EQ features a frequency range of 30 Hz to 450 Hz for thick, rich lows. The LMF band ranges from 200 Hz to 2.5 kHz, and the HMF band ranges from 600 Hz to 7 kHz, providing lots of flexibility in the crucial midrange. Finally, the high-frequency band features selectable frequencies from 1.5 kHz to 15 kHz for bright, sparkling highs.

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.

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.

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.
