Well done bro.i came across your channel not long ago and I must commend you for the good work. I would like to add another perspective to this conversation not to refute your video, but for us to exhaust the topic thoroughly. 1. Physical limitations. In other to split the entire frequency range within 31 bands on a physical device, there's bound to be some compromises . It is physically impossible to add a center frequency(Q) on each band on a GEQ. So, the bands not being exactly on the predetermined frequencies or changes affecting neighboring frequencies are to be expected. Putting steep notch filters on a GEQ wouldn't serve any practical application in my opinion, that's the work of a PEQ. GEQ is meant for broad stroke applications. 2. Brand/Quality. The quality of components used by a particular manufacturer within the device goes a long way to affect how the device functions. All these zongo lane/china devices we have in Ghana are wack. A good brand will always serve you better. 3. Phase. Phase shift is an unavoidable side effect of EQ, unless of course you use a linear phase EQ. As how drastic the phasing is will depend on how well the the device was manufactured. Since GEQs are minimum phase EQs, it is the manufacturer's duty to ensure that the device does exactly that, so as not to introduce any nasty problems within the phase domain. AD/DA. I believe the converters of your audio interface should also be taking into account within the context of the test. How much color is it imparting to the signal. In conclusion, I personally believe that we should be able to make use of whatever is at our disposal as audio engineers to make something happen. I'm sure you've pulled out some fantastic shows with some mediocre equipments in the past. The most important thing is to know your craft inside out. I have subscribed to your channel! I'd like to be a part of your success on this platform..... peace✌🏼
@@samuelkennethacquah1068 you're welcome bro. You'll be seeing more of my comments on your videos just to create conversations around the topics for the algorithm... ✌🏼
This DBX Seems to work fine, I dont see anything wrong, But learning is allways good :) Lowcut is to protect top speakers without sub, I guess the roll off frequenzy is at - 3 db so maby around 75 hz A 31 band eq has typ a q (how steep it cut or boost) of 4 +- again thats about 0,4 of an octave, an octave is half/double in frequenzy, eq 100 hz, one octave up is 200, one octave down is 50 Most if not all filters and eq's on std gear works by making fase shift, thats the princip The trick is if you eq before the filter of sub and high, the fase shift on sub and high is the same meening difference in fase between high and low is 0, så no sound problem. If you have sub on you can Lowcut protect Them by using the 20 and 25 hz slider, you can measure it yourself just remember a given cut freq is at - 3 db Have fun 😊
My guy...who told you low cut on a graphic eq is for protecting speakers without subs. IT IS NOT. Low cut is specifically designed to reduce feedback on transducers and pickups. You use it for microphone or some instruments that use pickup. Feedback ie from a mic placed too close to a speaker is always going to be be a bigger issue with low-end. Cut the low-end, and 90% of the problem is solved. the remaining feedback can be notched out with a 3-4db cut on individual frequency bands and a little less to their adjacent bands. That is the only use of the low cut. It will not protect speakers. You need a properly configured crossover to do that. Better yet, if you have powered speakers and subs, plug the full range signal in to the sub, then the output from the sub to the top. The sub will act as the crossover (since they are built in with their plate amplifier) so your tops will get only the signal that the sub is not able to play. If your tops are evenly matched with your subs, your system will be protected. The EQ should only be used for shaping the tonal structure of the sound source and for room correction. Never for speaker protection. You are right though, this DBX EQ (and every other graphical EQ) is behaving exactly how it was designed to.
@@nickloss2377 , Hello, Of course you can use low cut the way you like, but in my opinion you are wrong. Lowcut for mics normaly works around 80Hz not 50 thats too low, and lowcut for instruments should be at the input on the mixer so that it only affects 1 channel. Cause - when you use it on the eq which is placed after the mixer you lowcut everything incl kick drum and bass eg. So if you have subs on you dont want to cut ALL low end away :)
i don't understand what the problem is..? This is exactly how a graphic EQ is supposed to work. The low-cut is not and should never be used for "speaker protection" or to keep low frequencies out of top speakers. That's not a proper use of EQ. EQ is for manipulating the tonal characteristics of a signal in a listening environment..so could be used for room correction or simply for tuning an instrument, vocal or line input to make it sound more pleasing. This is why adjacent frequencies are going to be affected. It is a more musical and more pleasing to the human hearing when adjusting frequencies. Use a crossover if you want to cut the bass frequencies from playing back through your tops. That will protect your tops, but never use a EQ for that. That is the completely wrong use of it. tbh ive never seen anyone use an EQ in that way until i saw your video and read some of these comments. very strange...
actually we know EQ is for tonal balance control. but many people misuse this gear.in my video all i wanted to do is bring some image to what we push or press using this piece of gear. thanks for your comments and add up.

@@nickloss2377 some people actually uses that low cut as "crossover" wanted to poke everyone doing that type of act.

Pls what's the name of the software you are using in the system?
The name of the software is Smaart. U can visit www.rationalacoustic.com for it.
