Effects of Equalization on Vocals
For the best control over any audio signal, fully parametric EQ's are the best way to go.
80 to 125

160 to 250

315 to 500
Sense of power in some outstanding bass singers.

Voice fundamentals

Important to voice quality

630 to 1K
Important for a natural sound. Too much boost in the

315 to 1K range produces a honky, telephone-like quality.

1.25 to 4K

5 to 8K
Accentuation of vocals


Important to vocal intelligibility - Too much boost between 2 and 4KHz
can mask certain vocal sounds such as 'm', 'b', 'v'. Too much boost between
1 and 4KHz can produce 'listening fatigue'. Vocals can be highlighted at the 3KHz
area and at the same time dipping the instruments at the same frequency.
Accentuation of vocals:
The range from 1.25 to 8K governs the clarity of vocals. Too much in the area of 5 to 16K can cause sibilance.

Einstein

40Hz to 70Hz
These frequencies give music a sense of power. If over emphasized they can make things muddy and dull. Will also cloudy up some harmonic content.

80Hz to 125Hz
Too much in this area produces excessive 'boom'.

160Hz to 250Hz
This is the problem area of a lot of mixes. To much of this area can take away from the power of a mix but is still needed for warmth. 160Hz is a pet-peeve frequency of mine. Also, the fundamental of bass guitar and other bass instruments sit here.

300Hz to 500Hz
Fundamentals of string and percussion instruments.

400Hz to 1K
Fundamentals and harmonics of strings, keyboards and percussion. This is probably the most important area when trying to control or shape to a natural sound. The 'voice' of an instrument is in the mids.

To much in this area can make instruments sound horn-like.

800Hz to 4K
This is a good range to accentuate instruments or warm them up. Too much in this area can produce 'listening fatigue'. Boosts in the 1K to 2K range can make instruments sound tinny.

4K to 10K
Accentuation of percussion, cymbals, and snare drum.

Playing with 5K makes the overall sound more distant or transparent.

8K to 20K
This area is often what defines the quality of a recording or mix. This area can also help define depth and 'air' to mix. Too much can take away from the natural sense of a mix by becoming shrill and brittle.

pepsiman 兄

真要多謝師兄咁詳細解說, 小有 YAMAHA 呢類教學
小的都用緊舊型號機, 次次行完個 auto setting
睇各speaker 距離同大小再加番大db 值 就算
以上 setting 畫面都有研究過說明書其實睇完都唔知佢講乜, 所以通常唔搞
經閣下一番指導後要再深究 - 謝謝

thanks for pepsiman and Einstein sharing !!!

有冇Ching 可幫手...?

想問各ching,如左邊speaker近書櫃,咁左邊喇叭EQ是否要將某一段調整呢?如是者,how to set? THX.

如果你曾經試過auto set-up的話,
就會知道左右兩邊EQ係有o的分別,
而且db都會有約一個o既差距,
依個亦都係room EQ o既用途,
你可以嘗試吓推高EQ參數o既同時,
參考auto set-up o既左右差距而作調整
