DIfferent EQ
#998263 - 17/07/12 12:19 AM

Do different EQ's sound different even if the settings are the same?

Yeah, though I can't see a simple guide explaining exactly why. This one is rather technical.

http://www.audiosignal.co.uk/Resources/Why_do_equalisers_sound_different_A 4.pdf

One idea I pulled out of it at a glance is that different equalisers exhibit a different phase response - as I understand it, the processing introduces delay which affects the signal. They introduce different types of distortion.

There are also other factors at work in the colouration introduced by analogue hardware and attempts to model it.

They do and many factors allow this to be the case, component choice, component brand/spec/ tolerances, circuit topology, curves, proportional Q or not, eq circuit design, layout and type, physical construction, pots vs switches in stereo eq's, power supplies, transformer or electronic balancing of I/O, PCB layout, solid state vs valve, solid state vs monolithic opamp based, analogue or digital, band bypass switches or not, input and output impedance of unit itself and to that which it is connected.

All different, some subtle, some virtually inaudible and some obvious, any combination of the above may reside in any given product or design, none sound the same although do a similar job.
