The frequencies are (inHz):Low (L) 32 — 1.6kMid (M) 32 — 18kHigh (H) 1.7k — 18kNote that the frequencies are set in discrete steps; it isnot possible to set the center frequencies to interme-diate values.In addition, you can adjust the “Q” (the width of theeffect) in the center band from 0.25 to 16.TIP“Q” is defined as the center frequency of the equaliza-tion band divided by the bandwidth. A high Q valueprovides narrow filtering.As you adjust the equalization, the graph at the bot-tom of the screen changes to provide an idea of howthe equalization affects the signals.TIPYou can press and hold the SHIFT key and press theEQ key to “zero” (return to default setting) theselected channel’s EQ settings.There is also an on/off soft switch provided at theupper left of the screen to allow A/B comparison ofthe equalized and unequalized signals. Press SHIFT +YES to turn it on, and SHIFT + NO turn it on off (youcan also use the cursor).Effect sendThere is one stereo “loop” send (using the internaleffects) in addition two effect sends (using the exter-nal EFFECT SENDS jacks) for each channel.NOTERecording effects can also be inserted at the inputstage. See the section on effects (“Effects” on page 31)for full details of the effect architecture and use. Sucheffects are not affected by these channel sends.Press the channel’s SELECT key, followed by theSEND key (this order can be reversed).For each effect send, there is a soft switch at the leftside of the screen. Use the wheel to set this switcheither OFF or POST (post-fader) or PRE (pre-fader).TIP“Pre-fader” means that the channel fader does notaffect the level of the effect send, as opposed to “post-fader” where the effect send level is affected by thechannel fader setting.Set the level of each channel send (LVL) from 0 to 127.This screen also allows the master send level (MSTR)to be set (again from 0 to 127).
