A handy guide


I just found this on a reputable website. Seems like a handy bit of info to carry around with the PA. I know I will be printing it off and using it regularly. No doubt some of the "berties" on here will say it's wrong or that they already knew this. For everyone else, enjoy. I hope it helps.

Eq Settings

General:
20 Hz and below - impossible to detect, remove as it only adds unnecessary energy to the total sound, thereby most probably holding down the overall volume of the track
60 Hz and below - sub bass (feel only)
80(-100) Hz - feel AND hear bass
100-120 Hz - the "club sound system punch" resides here
200 Hz and below - bottom
250 Hz - notch filter here can add thump to a kick drum
150-400 Hz - boxiness
200 Hz-1.5 KHz - punch, fatness, impact
800 Hz-4 KHz - edge, clarity, harshness, defines timbre
4500 Hz - exteremly tiring to the ears, add a slight notch here
5-7 KHz - de-essing is done here
4-9 KHz - brightness, presence, definition, sibilance, high frequency distortion
6-15 KHz - air and presence
9-15 KHz - adding will give sparkle, shimmer, bring out details - cutting will smooth out harshness and darken the mix

Kicks:
60Hz with a Q of 1.4 -- Add fullness to kicks.
5Khz with a Q of 2.8 -- Adds attack to Kicks
bottom (60 - 80 Hz),
slap (4 kHz)
EQ>Cut below 80Hz to remove rumble
Boost between 80 -125 Hz for bass
Boost between 3 - 5kHz to get the slap
PROCESSING> Compression 4:1/6:1 slow attack med release.
Reverb: Tight room reverb (0.1-0.2ms)

General:
Apply a little cut at 300Hz and some boost between 40Hz and 80Hz.
Control The Attack:
Apply boost or cut around 4KHz to 6KHz.
Treat Muddiness:
Apply cut somewhere in the 100Hz to 500Hz range.
kick>> bottom depth at 60 - 80 Hz, slap attack at 2.5Hz

Snares:
100Hz with a Q of 1.0 -- Add fullness to snare
200Hz - 250Hz with a Q of 1.4 -- Adds wood to snares
3Khz with a Q of 1.4 -- Adds atack to snare.
7Khz with a Q of 2.8 -- Adds Sharpness to snares and percussion
fatness at 120-240Hz
boing at 400Hz
crispness at 5kHz
snap at 10kHz
fatness (240 Hz), crispness (5 kHz)
EQ> Boost above 2kHz for that crisp edge
Cut at 1kHz to get rid of the sharp peak
Boost at 125Hz for a full snare sound
Cut at 80Hz to remove rumble
PROCESSING> Compression 4:1 slow attack med release.
Reverb: Tight room reverb (0.1-0.2ms)
snare>> fatness at 240HZ, crispness at 5 KHz

Vocals
General:
Roll off below 60Hz using a High Pass Filter. This range is unlikely to contain anything useful, so you may as well reduce the noise the track contributes to the mix.
Treat Harsh Vocals:
To soften vocals apply cut in a narrow bandwidth somewhere in the 2.5KHz to 4KHz range.
Get An Open Sound:
Apply a gentle boost above 6KHz using a shelving filter.
Get Brightness, Not Harshness:
Apply a gentle boost using a wide-band Bandpass Filter above 6KHz. Use the Sweep control to sweep the frequencies to get it right.
Get Smoothness:
Apply some cut in a narrow band in the 1KHz to 2KHz range.
Bring Out The Bass:
Apply some boost in a reasonably narrow band somewhere in the 200Hz to 600Hz range.
Radio Vocal Effect:
Apply some cut at the High Frequencies, lots of boost about 1.5KHz and lots of cut below 700Hz.
Telephone Effect:
Apply lots of compression pre EQ, and a little analogue distortion by turning up the input gain. Apply some cut at the High Frequencies, lots of boost about 1.5KHz and lots of cut below 700Hz.
vocals>> fullness at 120 Hz, boominess at 200 - 240 Hz, presence at 5 kHz, sibilance at 7.5 - 10 kHz

Hats:
10Khz with a Q of 1.0 -- Adds brightness to hats and cymbals
Hi Hat & Cymbals: sizzle (7.5 - 10 kHz), clank (200 Hz)
EQ> Boost above 5kHz for sharp sparkle
Cut at 1kHz to remove jangling
PROCESSING> Compression use high ratio for high energy feel
Reverb: Looser than Bass n Snare allow the hats and especially the Rides to ring a little
Get Definition:
Roll off everything below 600Hz using a High Pass Filter.
Get Sizzle:
Apply boost at 10KHz using a Band Pass Filter. Adjust the bandwidth to get the sound right.
Treat Clangy Hats:
Apply some cut between 1KHz and 4KHz.
hi hats/cymbals>> clank or gong sound at 200 Hz, shimmer at 7.5 kHz - 12 kHz

Guitar:
Treat Unclear Vocals:
Apply some cut to the guitar between 1KHz and 5KHz to bring the vocals to the front of the mix.
General:
Apply a little boost between 100Hz and 250Hz and again between 10KHz and 12KHz.
Acoustic Guitar
Add Sparkle:Try some gentle boost at 10KHz using a Band Pass Filter with a medium bandwidth.
General:
Try applying some mid-range cut to the rhythm section to make vocals and other instruments more clearly heard.
Other:
Voice: presence (5 kHz), sibilance (7.5 - 10 kHz), boominess (200 - 240 kHz), fullness (120 Hz)
Electric Guitar: fullness (240 Hz), bite (2.5 kHz), air / sizzle (8 kHz)
Bass Guitar: bottom (60 - 80 Hz), attack (700 - 1000 Hz), string noise (2.5 kHz)
Toms: attack (5 kHz), fullness (120 - 240 Hz)
Acoustic Guitar: harshness / bite (2 kHz), boominess (120 - 200 Hz), cut (7 - 10 kHz)
Bass - Compressed, EQ'd with a full bottom end and some mids
rack toms>> fullness at 240 Hz, attack at 5 kHz
floor toms>> fullness at 80 - 120 Hz, attack at 5 kHz
horns>> fullness at 120 - 240 Hz, shrill at 5 - 7.5 kHz
strings>> fullness at 240 Hz, scratchiness at 7.5 - 10 kHz
conga/bongo>> resonance at 200 - 240 Hz, slap at 5 kHz

General Frequencies:
EQ Reference: Frequencies
50Hz
Boost: To thicken up bass drums and sub-bass parts.
Cut: Below this frequency on all vocal tracks. This should reduce the effect of any microphone 'pops'.
70-100Hz
Boost: For bass lines and bass drums.
Cut: For vocals.
General: Be wary of boosting the bass of too many tracks. Low frequency sounds are particularly vulnerable to phase cancellation between sounds of similar frequency. This can result in a net 'cut of the bass frequencies.
200-400Hz
Boost: To add warmth to vocals or to thicken a guitar sound.
Cut: To bring more clarity to vocals or to thin cymbals and higher frequency percussion.
Boost or Cut: to control the 'woody' sound of a snare.
400-800Hz
Boost: To add warmth to toms.
Boost or Cut: To control bass clarity, or to thicken or thin guitar sounds.
General: In can be worthwhile applying cut to some of the instruments in the mix to bring more clarity to the bass within the overall mix.
800Hz-1KHz
Boost: To thicken vocal tracks. At 1 KHz apply boost to add a knock to a bass drum.
1-3KHz
Boost: To make a piano more aggressive. Applying boost between 1KHz and 5KHz will also make guitars and basslines more cutting.
Cut: Apply cut between 2 KHz and 3KHz to smooth a harsh sounding vocal part.
General: This frequency range is often used to make instruments stand out in a mix.
3-6KHz
Boost: For a more 'plucked' sounding bass part. Apply boost at around 6KHz to add some definition to vocal parts and distorted guitars.
Cut: Apply cut at about 3KHz to remove the hard edge of piercing vocals. Apply cut between 5KHZ and 6KHz to dull down some parts in a mix.
6-10KHz
Boost: To sweeten vocals. The higher the frequency you boost the more 'airy/breathy' the result will be. Also boost to add definition to the sound of acoustic guitars or to add edge to synth sounds or strings or to enhance the sound of a variety of percussion sounds. For example boost this range to:
Bring out cymbals.
Add ring to a snare.
Add edge to a bass drum.
10-16KHz
Boost: To make vocals more 'airy' or for crisp cymbals and percussion. Also boost this frequency to add sparkle to pads, but only if the frequency is present in the original sound, otherwise you will just be adding hiss to the recording.

Very intresting. My desk however is like my guitar amp.......top middle and bottom, and watch out for the hotspot (what's a hot spot not?)

Worth printing out though, one day I'll be faced with a monster graphic equaliser and that info could be handy. Thanks for posting.

Ha ha, I don't have limitations...just areas for improvement. And even then, only a few :oD

Thank you Cottonhouse Shakers. I think even on the simplest of desks, this info could give some indications as to whether top, middle or bottom need some adjustment.

I think it's useful to share more techy stuff.

Yeah well worth getting into and doing some delving and testing with this. Be surprised how knowledge on these can help you get the optimum output out of any gear.

Another feather to your cap - if you have an annoying feedback and can match the tone as a note on a guitar you can roughly estimate an approx frequency range to cut on EQ's.
So example - concert pitch tuning of 'A' (4 on keyboard - middle A) is 440hz. So if you have a hum or constant drone that is around the same pitch as middle A, a cut around the 500HZ and below should rid / lower it's presence.

Worth reading about fundamental, harmonic and resonant frequencies too. Resonant can be a common cause of may feedback situations...not sure if Mr Hendrix knew about this but he did a great deal of experimenting!!

The most fascinating sound check that I ever heard was by Bob Brozman. He just sat on stage with his guitar and went through what seemed like every frequency saying how much to cut or boost....higher! lower! What is it with me today? I think I'm in game show mode! lol

Nice one drum bloke. I'm really getting into all this sound engineering stuff. It ticks all my boxes - technical, detailed and great for people with obsessive compulsive disorder!

The only problem I have is that (being a drummer) I can't play and hear the FOH sound at the same time. The guys in the band seriously SUCK at playing the drums - even one drum at a time!!

If anyone wants a "fresh pair of ears" to come and listen to their sound and maybe give some pointers (I wouldn't call it advice as I'm not qualified and certinaly wouldn't charge for it!) then just give me a shout on here.

Ha ha, good point well made Aiden, but I was actually referring to listening to each instrument individually. For overall mix, we'll have to rely on "tone deaf" Phelps!

I know a couple of drummers who get into sound engineering and went onto studio production or P.A. hire. I think it stems from playing the Acoustic kit most of the nuances of sound are there!
Pitch, tone, timbre, percussive transients (attack sustain decay), overtone, resonance and dynamics. Right through the frequency range from the lower registers of the large toms and bass drums, middle - snare and toms, to higher registers, Snare and cymbals. All that and not a single 13 amp plug in site!!

Another good point Drum Bloke.....if I could bottle all my experience in finding the "perfect" drum sound, I could sell it for fortunes.

Different drums, different skins, different tuning, different methods of dampening, different sticks. It's a bloody minefield!

I've offered my assistance on here previously, but nobody took advantage. I doubt they will here either, but it's nice to be nice and it's only polite to offer :oD

# Posted by ST Photography - VIVA LA COMMU... - 16/02/2010, 15:02 (GMT)

The bass drum is very difficult to capture. In my opinion it has to be present in the overall mix, but not so loud that it muddles up the overall sound. Something that has come from learning more about frequencies - it's not all about the volume. Pick out the right frequencies and you will hear the difference.

There's nothing sweeter than a nice bass drum and a bass guitar playing off each other in the mix.

Yeah it is difficult checking FOH on your own kit. Even with another drummer playing it it will change slightly as no 2 drummers play quite the same...

I used to do gigs and the singer was convinced he was a drummer, he used to sound check the kit after setting up the sound with me playing. He would say "Sound ace!, 'ere let me play them and you have a listen" The bassist afterwards would have a quick word in me shell like would say "sounds fuck all like when you played it"

You can't really have a set amount of EQ parameters either as the kit changes with the room acoustics. Yeah 'leccy kits do the job but I don't have anywhere as much fun or 'return on my investment'...

I've never been a big fan of electric kits. Even the most expensive cannot give you that authentic feel/sound. Great for practice, but would never use one "live".

The bass drum sound in a thrash metal band is very different to (for example) John Bonham's sound. Therefore there is only so much tweaking that you can do without loosing the correct sound. Some sound engineers wet themselves at a powerful bass drum sound which to be honest I find ridiculous when it is louder than the vocals. They spend ages playing with the sound of the bass drum but when the singer line checks he rarely gets to say more than "one-two testing"

Not sure - acoustic wise it's the largest drum so moves the most.
air...

To me this is something I notice at big gigs, the kick sound is massive compared to the rest of the kit. I hate playing gigs where I struggle to hear my bass drum!!

True to say also (crossing boundaries here) that in the (naff) hardcore garage trance dance scene the Kick drum sound is right up front above anything else....

The one thing I've found is that when you ask a musician to "play their instrument" so you can set the gain/peak they tickle it like it's a bloody kitten. Then when it comes to playing the gig, they thrash the bloody life out of it.

TOP TIP #1: At a soundcheck, play it like you would play during the gig. Otherwise the sound check is utterly pointless!! That goes for singers too.

Thereby oveloading the channel, peaking to buggery and back!!
Absolutely spot on - and probably the biggest cause of bad sound and arguments I've had over the years .... "Play it like you fuckin mean it!!!" ....... aaaaaaaaarghhhh!!!

Drummers always make the best sound men ! !

It all can be sorted with trial and error, but if you have no idea on which instruments work at which frequency then its gonna take you a long time to get it right, also need to be sure your speakers and cut offs are suitable for your use.

In full on mode we use 8 mics on my kit, I try never to let a note go un-mic'd !!
