Pros & Cons
👍 Pros
- FBQ Feedback Detection System visually identifies problem frequencies in real time, speeding up the ring-out process during live sound checks.
- Full 31-band resolution on two independent channels provides precise tonal control across the entire audible spectrum.
- Dedicated mono subwoofer output with adjustable crossover eliminates the need for a separate crossover unit in sub-equipped systems.
- Sweepable high and low cut filters per channel let you remove rumble, hiss, and other unwanted noise beyond the graphic bands.
- Both 1/4-inch TRS and gold-plated XLR connectors offer flexible integration with a wide range of professional audio equipment.
👎 Cons
- Rack-mounted unit requires two rack spaces, which may be a consideration in already-full equipment racks.
- Fader travel is relatively short, making very fine adjustments on individual bands more difficult by feel alone.
- No built-in limiter or dynamic processing, so clipping must be managed externally in the signal chain.
- The unit can introduce a small amount of noise at higher gain settings, which may be noticeable in quiet studio monitoring environments.
- No digital I/O or USB connectivity for integration with DAW-based workflows.
Frequently Asked Questions
What does the FBQ Feedback Detection System do?
The FBQ system uses LED indicators on the fader slots to show which frequencies are feeding back in real time, allowing you to quickly identify and cut problem frequencies before they become audible to the audience. It can also function as a basic audio spectrum analyzer.
Can the FBQ3102 be used in mono as well as stereo?
Yes, each channel operates independently with its own set of 31 band faders, so you can run both channels in stereo or use a single channel for mono applications.
What is the dedicated subwoofer output for?
The mono subwoofer output has an adjustable crossover frequency, allowing you to send a filtered low-frequency signal directly to a subwoofer amplifier without needing a separate crossover unit in your signal chain.
What connector types does the FBQ3102 use?
It features servo-balanced inputs and outputs on both 1/4-inch TRS jacks and gold-plated XLR connectors, giving you flexibility to integrate with professional and semi-professional audio systems.
Do the high and low cut filters work independently per channel?
Yes, each channel has its own sweepable high cut and low cut filters, so you can tailor the frequency range for each side of the stereo signal separately.
