The  BEHRINGER PEQ2200 is an extremely effective and musical frequency correction and sound-shaping tool with center frequency, bandwidth and amplitude adjustment for each filter. Its state-variable, constant-Q filters and parallel filter configuration ensure musical operation, while overlapping frequency bands allow up to 30 dB of level correction.

Product Features:

• Flexible equalization (from gentle contouring to extreme correction to creative sound shaping) for all recording, post-production or live applications
• High-precision state-variable filters with constant-Q characteristic
• Parallel filter architecture ensures minimal phase shifting
• Ultra low-noise 4580 audio operational amplifiers for outstanding audio performance
• Sweepable High and Low-pass filters remove unwanted frequencies
• In/out switch plus adjustable bandwidth per frequency band (bandwidth 0.03 octave – 2 octaves)
• Broadly overlapping frequency bands allow extreme attenuation or boost
• Extremely accurate 12-segment LED input/output metering
• High-quality detented potentiometers and illuminated switches
• Power-up delay prevents dangerous “thumps”
• Relay-controlled hard bypass with auto-bypass function in case of power failure
• Servo-balanced inputs and outputs with gold-plated XLR and 1/4" TRS connectors
• Optionally retrofitable with high-performance BEHRINGER OT-1 output transformer
• High-quality components and exceptionally rugged construction ensure long life
• Conceived and designed by BEHRINGER Germany

The BEHRINGER ULTRA-Q has five parametric filters organized in 5 different frequency bands.In addition to that there are low cut and high cut filters.A 12-segment LED display shows the input or output level.

1.) The AUDIO IN/OUT switch is used to enable/disable the entire equalizer section in the audio path.The switch uses a relay-controlled hard-bypass function,i.e. as long as it is not pressed or if the unit is switched off,the inputs are directly connected to the outputs.

2.) Use the I/O METER IN/OUT switch to select the input source.Press it to display the input level.

3.) The LEVEL meters are used to monitor the signal levels,so as to avoid distortion caused by overloading.

4.) The INPUT control determines the input level applied to the device and can be set within a range from -15 to +15 dB.

5.) The LOW CUT control adjusts the lower cut off frequency of the ULTRA-Q PRO. The ULTRA-Q PRO.The high-pass filter can be tuned from 10 to 400 Hz.In the 10 Hz position the signal passes unchanged.

6.) The HIGH CUT control adjusts the upper cutoff frequency of the ULTRA-Q PRO.The low-pass filter can be tuned from 2.5 to 30 kHz position the signal passes unchanged.

7.) The FREQUENCY control selects the filters center frequency,which can be freely chosen from within the frequency range of the associate band.

8.)The BANWIDTH control determines the slope or quality of the filter. Settings from 0.03(Q=43) to 2 octaves (Q=0.67) are possible.

9.)The LEVEL control determines the amout of level boost/cut.The setting range id from -15 to +15 dB.

10.) The individual IN/OUT switches allow for enabling/disabling specific bands in the audio path.

11.) SERIAL NUMBER.Please take the time to have the warranty card filled out completely by your specialized dealer and return it within 14 days after the date of purchase,so as to be entitled to benefit from our extended warranty.

12.) FUSE HOLDER/VOLTAGE SELECTOR.Please make sure that your local voltage matches the voltage matches the voltage indicated on the unit,before you attempt to connect and operate the ULTRA-Q PRO.

13.)MAINS CONNECTION.Use the enclosed power cord to connect the unit to the mains.

14.)AUDIO IN.These are the audio inputs of your ULTRA-Q PRO,available both as balanced 1/4" jack and XLR connectors.

15.)AUDIO OUT.These are the audio outputs of your ULRA-Q PRO.Matching phone jack and XLR connectors are wired in parallel.
