    Comments about dbx 215s Dual Channel 15-Band Graphic Equalizer:

    I currently have this in the mixer's effects loop that starts with a Lexicon MX200 that splits the signal into a DOD crossover into a DBX compressor and ends with this two-channel, fifteen band graphic EQ. Used this way, it is a subtle piece of the puzzle. Wiring it between the mixer's output and the preamp makes it easier to get the correct amount of gain into the EQ to let it shine on its own.

    A few more LEDs for the gain would be nice. As it is, you get indications for -10, 0, +10 and +18dB. My goal is to hit zero for the most part and maybe light up the +10 on the most severe peaks. I use the rack for PA and for bass guitar and it works fine for both.

    I have not experienced any popping sounds when using the bypass, lo cut or range selection buttons after six months or regular use.

    Not bad


    from Rio Rancho, NM

    Comments about dbx 215s Dual Channel 15-Band Graphic Equalizer:

    Just bought this unit. right off as the previous reviewer quoted is that there is NO on/off switch. Another thing that I find annoying is that when you use the by pass switch, no matter if you are turning the bypass on or off, it makes a hell of a POP throughout the entire system. and when you are playing live and setting up sound (granted you probably wont' be using the bypass switch) but if you do, you had better turn everything off or you are going to get blasted. other than that, the unit seems to be very good. Quite operation and the sliders are very responsive. I had two different Nady units, on one, a channel just went out completely and the other had a VERY noticible hissing noise in it that could not be EQed out. they both had the same issue also with the bypass switch that this unit has. Because of the previously mentioned issues with the NADY's, is the reason I ran to GC to get a new unit and this is what I picked up. definately and improvement over the NADY's that I had (2 ea).

    good quality

    By john curtis

    from missouri

    Comments about dbx 215s Dual Channel 15-Band Graphic Equalizer:

    the dbx 215s is a good quality equalizers, the electronic parts used to build is good quality, knobs, sliders etc.. for sound, i would rate it a four, 6db setting is ok, but, using the 12db would be recommended. this unit is best used for studio recording, live sound, or even just home use.. unit is built good, and designed fairly well... very low distortion, quiet operation... one draw back with this unit, is a main on and off switch..."there is no switch" for the most part, i would recommend this equalizer....
