44. MAIN EQUALIZER

The 9-band stereo graphic equalizer allows you to tailor the sound of your main mix to suit your ex- traordinarily-delicate sense of audio right and wrong.

Each slider allows up to 15 dB of boost and cut, with 0 dB (no change in level) at the center. The frequency bands are: 63, 125, 250, 500, 1 k, 2 k, 4 k, 8 k, and 16 kHz

The EQ affects the main mix line-level outputs

[16]and mono output [17], as well as the speaker- level outputs [3] if the internal amplifiers are playing the main mix.

The EQ section comes before the main fader [59], and the main meters [48]. As you adjust the EQ, keep an eye on the meters in case you overdo it and take the levels into overload.

The main EQ assign switch (46) allows you to use this EQ to adjust the monitor 2 output instead of the main mix.

42. POWER LED

This LED comes on when the powered mixer is plugged into the correct-voltage AC mains supply, and the power switch [2] is on.

If the LED is not on, then make sure the AC power is live, and that both ends of the power cord are correctly inserted. If Zombies have taken over the power station again, and all the lights in town are off, this LED may not come on. (This would be the least of your worries.)

As with the channel EQ, just take it easy. There is a large amount of adjustment, and if you are not care- ful, you can upset the delicate balance of nature. Re- member that even the happiest audience of old ladies can turn on you like a pack of wild dogs. Although it may not seem cool to turn down controls, with EQ it is often your best option. Turn down any offending frequency range, rather than boost the wanted range. Having many sliders will allow you to reduce the level of some frequency bands where feedback occurs.
