Equalizers: Behringer UltraGraph FBQ6200

[Big Daddy]

I am sure most of you already know why room correction and equalization is important in audio. It may still be helpful to read Why Do We Need Equalization and Room Correction? and check the Phonic PAA3 Audio Analyzer thread.

Room correction and equalization was missing from my two-channel room. After spending some time investigating the different options, I decided to buy the Behringer UltraGraph Pro FBQ6200 stereo one-third octave graphic equalizer. The PEQ6200 is Behringer's top-of-the-line UltraGraph equalizer. It is a 31-band graphic equalizer with FBQ feedback detection System. Because the equalizer uses only pro balanced input/output, I have already ordered the proper cables.

• Audiophile 31-band stereo graphic equalizer for live and studio applications
• Revolutionary FBQ Feedback Detection system instantly reveals critical frequencies and can also be used as audio analyzer
• Dedicated Limiters with gain reduction meters for each channel protect your sound system from overload and distortion
• Pink noise generator provides test signals to adapt your sound system to any room acoustics
• Mono subwoofer output with dedicated level control and adjustable crossover frequency
• Additional sweepable high and low-cut filters for each channel remove unwanted frequencies e.g. floor rumble, hiss etc.
• Highly accurate 8-segment LED input/output metering and input gain controls for easy level setting
• Ultra-low noise audio operational amplifiers for highest signal integrity
• Relay-controlled hard bypass with an auto-bypass function during power failure (failsafe relay)
• Servo-balanced inputs and outputs with 1/4" TRS and gold-plated XLR connectors
• Shielded toroidal power transformer for ultra-low noise performance
• High-quality components and exceptionally rugged construction ensure long life
• Conceived and designed by BEHRINGER Germany

Most online dealers sell it for $180 to $197. I managed to buy it from UniqueSquared Ebay store for $165. The price was too good to be true and I jumped on it. This is the fifth Behringer product that I have purchased in the past two years. I already own three Behringer amplifiers (EP4000, EPX3000, and EPX4000) and a Behringer ECM8000 Condenser calibration microphone. I bought the three amplifiers from the same Ebay dealer. They have by far the best prices and are very reliable in shipping the products within twenty four hours.

The equalizer is expected to be delivered by the middle of next week. I plan to run one third octave test tones through each speaker and measure the response with a couple of SPL meters and then equalize each speaker separately. It will be a long and laborious process. I will keep you posted.
