Manual-2Controls and OperationParametric filter controlsGAIN: Range is +12 dB to -24 dB, with a 0 dB center detent.BW (bandwidth): Range is 1/ 12 to 2 octaves with each dot representing ¼ octave.FREQUENCY: Total range is 12.5 Hz to 20 kHz, with the multiplier switch.Each Hz multiplier covers a 4 octave range:x0.1 operates from 12.5 Hz to 200 Hzx1 operates from 125 Hz to 2 kHzx10 operates from 1.25 kHz to 20 kHzIndividual switches BYPASS each filter without affecting the others.Individual OL (overload) warning indicators light at 0 dBFS (digital clipping).Low ShelfFilters A1 and B1 include a LOW SHELF mode.When the LOW SHELF switch is in, the yellowindicator is lit and the filter is in LOW SHELF mode.Filter B1 LOW SHELF mode is disabled in 10-BAND mode. The BW control has no effect in LOWSHELF mode. The minimum Low Shelf frequency is25 Hz (0.1 multiplier). Settings below 25 Hz defaultto 25 Hz.High ShelfFilters A5 and B5 include a HIGH SHELFmode. When the HIGH SHELF switch is in, theyellow indicator is lit and the filter is in HIGHSHELF mode. Filter A5 HIGH SHELF mode isdisabled in 10-BAND mode. The BW control has noeffect in HIGH SHELF mode.Tone controlsIndependent, 3-band TONE controls are pro-vided for each channel. The Low-Mid cutoff is 300Hz. The Mid-High cutoff is 4 kHz. These Tonecontrols are enhanced, 2nd -order filters. The HIGHand LOW filters are shelving. Phase shift is zerodegrees with the controls at their center detent. Onlythe A-channel Tone controls are active in 10-BANDmode.Cut Filters2 nd -order Butterworth LOW- and HIGH-CUTFILTERS are provided for each channel. The rangeof the LOW-CUT Filter is 15 Hz to 240 Hz. Therange of the HIGH-CUT Filter is 5 kHz to 20 kHz.Only the A-channel controls are active in 10-BANDmode.∞ ∞∞ ∞2octdB1.5 1.5Hz1255002502k1k1 / 12120-6 6-24BYPASSGAIN BWx1x10x0.1FREQUENCYA2OL2octdB1.5 1.5Hz1255002502k1k1/12120-6 6-24BYPASSGAIN BWLOW SHELFx1x10x0.1FREQUENCYA1OL∞ ∞∞ ∞2octdB1.5 1.5Hz1255002502k1k1/12120-6 6-24BYPASSGAIN BWHIGH SHELFx1x10x0.1FREQUENCYA5OL∞∞ ∞∞∞ ∞6 6+ +0 0LOW MID HIGHTONE∞ ∞∞ ∞20k7k14k5k10k151203024060LOW HIGHCUT FILTERS-24+14-22-20-18-16-14-12-10-8-6-4-20+2+4+6+8+10+12dBu20 20k50 100 200 500 1k 2k 5k 10kHz-24+14-22-20-18-16-14-12-10-8-6-4-20+2+4+6+8+10+12dBu20 20k50 100 200 500 1k 2k 5k 10kHz-40+10-35-30-25-20-15-10-50+520 20k50 100 200 500 1k 2k 5k 10kHzdbuLow Off,Low Off,MidMid ‘0’,Hi OffHi OffLowLow ‘0’, Mid +6, Hi, Mid +6, Hi ‘0’LowLow ‘0’,Mid Off,Mid Off,HiHi ‘0’Low +6, MidLow +6, Mid ‘0’, Hi +6, Hi +6Low Off,Mid ‘0’,Hi OffLow ‘0’, Mid +6, Hi ‘0’Low ‘0’,Mid Off,Hi ‘0’Low +6, Mid ‘0’, Hi +6-40+10-35-30-25-20-15-10-50+520 20k50 100 200 500 1k 2k 5k 10kHzdbu
