Mixing Console Master Equalizer Settings Usually an equalizer is used to correct the sound output from amps or speakers to match the special character of the room. The sound is divided into several frequency bands, allowing you to correct the sound by raising or lowering the level for each band. The equalizer allows you to adjust the tone or timbre of the sound to match the performance space, or to compensate for certain acoustic characteristics in your room. For example, you can cut some of the low range frequencies when playing on stages or in large studio spaces where the sound is too "boomy," or boost the high frequencies in rooms and close spaces where the sound is relatively "dead" and free of echoes. The PSR-9000 possesses a high grade five-band digital equalizer function. With this function, a final effect-tone control-can be added to the output of your instrument. An edited PRESET or USER curve can be stored to USER 1. An edited PRESET or USER curve can be stored to USER 2. Adjusts the overall gain of all EQ bands simultaneously. The PRESET and USER curves can be edited as required via the corresponding LCD buttons - EQ1 through EQ5. Each of the 5 bands can be boosted ("+" values) or cut ("-" values) by up to 12 dB. Q Gain FREQ Whenever an EQ band is edited the corresponding EQ value is highlighted and the number of the edited band appears above the Q and FREQ controls. The Q and FREQ controls can then be used to adjust the Q (bandwidth) and the FREQ (center frequency) of the selected band. The higher the "Q", the narrower the bandwidth. The available FREQ range is different for each band. qEffect Signal Flow Chart DRY LINE R1 R2 R3 LEFT MIC STYLE DSP (4) DSP (5) DSP (6) 3 Band EQ Noise Gate Compressor DSP (7) DSP (8) DSP (9) Vocal Harmony DSP (3) Connection is set to Insertion Dry Rev Send Cho Send Dry Rev Send Cho Send Dry Rev Send Cho Send Dry Rev Send Cho Send Dry Rev Send Cho Send Dry Rev Send Cho Send DSP Send Reverb (1) DSP (1) Chorus (2) DSP (2) Master EQ OUT DSP (3) Connection is set to System q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q Reference 125 123
