Included in this bundle is an XLR cable, a 1/4-inch instrument cable and a handy polishing cloth. Professional audio engineers have known for decades that a good EQ makes all the difference in how a performance is perceived. Although multi-band graphic equalizers have been around for a long time, they have changed very little... until now! BEHRINGER ULTRAGRAPH PRO Series equalizers take a giant leap forward technologically, providing robust feature sets and our proprietary FBQ Feedback Detection System--at a price that makes them a must-have for anyone who records or operates a live sound system. The low-frequency sound range requires special attention. That"s why the FBQ-PRO Series features a Low Cut filter, in addition to the frequency faders, to help remove unwanted low frequencies such as floor rumble, room resonance, electrical hum, etc. This filter is preset on the FBQ1502 to remove all content below 25 Hz, which can really eat into your power amp"s headroom. On the FBQ3120 and FBQ6200 models we take it a step further, including variable High- and Low-Cut filters per channel with a sweepable frequency dial for even more control. Speaking of special low-frequency tools, all three FBQ-PRO models feature a dedicated subwoofer output with an adjustable (30 -- 200 Hz) cut-off frequency. Balanced XLR Outs are provided so you can connect to power amps, or directly to your active subwoofers, without any additional hardware--just another example of how BEHRINGER saves you money.
