Zahl EQ1 Stereo Equalizer – No Longer Available

Legendary Zähl EQ from the state-of-the-art mixing console AM1 in the API 500 format

Product Description

The Zahl EQ1 Stereo Equalizer is a highly detailed parametric stereo equalizer occupying only two spaces in a 500 series rack. Each channel is equipped with a true bypass button, frequency selection and output trim/gain.

The HI band ranges from 2 kHz all the way up to 20 kHz with the option of being a shelf or bell curve EQ.

The Hi-Mid channel ranges from 600 Hz up to 6 kHz, engaging the button above the Q on this channel will change the shape of the EQ curve. LO-MID ranges from 200 Hz to 2 kHz, same as the high mid channel. Engaging the button above the Q on this channel will change the shape of the EQ curve.

The LO channel functions the same as the Hi channel, ranging from 30 Hz up to 300 Hz with the option of a shelf or bell curve EQ. Engaging the LO-CUT gives you a high-pass filter ranging from 25 Hz to 250 Hz.

The EQ GAIN button will expand the trim or gain of each EQ channel by 5 dB or 15 dB. I/O gain will boost the overall signal level either on the Input or Output of the EQ1 by 5 dB or 15 dB.

A true bypass switch will remove the EQ1 from the signal path entirely. The small O/L Signal LED allows you to keep an eye on a proper audio level into your DAW or Tape Machine.

Great sounding EQ with lots of very useful features. A single set of controls for both channels makes setup effortless. The high band is excellent for adding air.

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.

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.
