Peq 55 Manual - Performance Audio

OPERATORS MANUAL PEQ 55 PARAMETRIC EQUALIZER Quick Start Everyone knows how to use a parametric equalizer, right? You set the filter GAIN to its maximum and turn the FREQUENCY control until you find a pesky resonance that, when excited by a few extra dB, fries your speaker or causes hearing damage. There, problem solved. What did you say? Connect the PEQ’s Inputs and Outputs to virtually any type of audio device using XLR, ¼" TRS or Euroblock connectors. You may use any combination of Outputs simultaneously if desired, but don’t try to save a few bucks by plugging multiple sources into the Inputs and expecting them to mix — they won’t. It will simply sound bad and no amount of EQ will fix it. Polarity convention on the XLR jacks is pin 2 positive, pin 3 negative and pin 1 shield (chassis ground). With the wiring out of the way it’s time to polish your golden ears and start making adjustments. Fire up some music and adjust the input and output LEVELs for good headroom and optimum signal-to-noise. Always heed the OL (overload) indicator! And check to make sure the channel BYPASS/EQ and individual filter BYPASS switches are properly engaged, and that the FREQUENCY multiplier switch (x0.1, x1, x10) is in the desired position. Filter bands A1 and B1 feature a switchable LOW SHELF response. Bands A5 and B5 feature a switchable HIGH SHELF response. Further flavor the mix using the channel TONE controls and CUT FILTERS. The PEQ’s A/B switches are an especially unique feature. Understand their use and you’ll unlock some of the device’s analog-controlled digital magic. Misunderstand their use and you’re in for a few surprises. Repeat after me: either audio channel can follow either set of filters, as set by the A/B switch. For example, in normal dual 5-BAND mode set the top row switch to A (the Left channel), and the bottom row switch to B (the Right channel). These switches also affect the CUT FILTERS, TONE controls and LEVELS. Or perhaps you want to equalize both sides of a stereo system identically using one set of controls. Set both switches to A and now the top row of filters controls both audio channels. Set both switches to B and use the bottom row of filters to create a totally different EQ curve. Do an A/B comparison of the two curves by toggling the (you guessed it) A/B switches. Try doing that with an analog EQ. Need more filters? Switch to 10-BAND mode and you now have ten fully overlapping filters to use on a stereo or mono source. The outputs mute momentarily when switching between 5- and 10-BAND modes.

Manual- Controls and Operation Parametric filter controls GAIN: 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 Hz x1 operates from 125 Hz to 2 kHz x10 operates from 1.25 kHz to 20 kHz Individual switches BYPASS each filter without affecting the others. Individual OL (overload) warning indicators light at 0 dBFS (digital clipping). Low Shelf Filters A1 and B1 include a LOW SHELF mode. When the LOW SHELF switch is in, the yellow indicator 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 LOW SHELF mode. The minimum Low Shelf frequency is 25 Hz (0.1 multiplier). Settings below 25 Hz default to 25 Hz. +14 +12 +10 +8 +6 +4 +2 d 0 B u -2 -4 -6 -8 -10 -12 -14 -16 -18 -20 -22 -24 20 50 100 200 500 1k 2k 5k 10k 20k 1k 2k 5k 10k 20k Hz High Shelf Filters A5 and B5 include a HIGH SHELF mode. When the HIGH SHELF switch is in, the yellow indicator is lit and the filter is in HIGH SHELF mode. Filter A5 HIGH SHELF mode is disabled in 10-BAND mode. The BW control has no effect in HIGH SHELF mode. +14 +12 +10 +8 +6 +4 +2 d B u 0 -2 -4 -6 -8 -10 -12 -14 -16 -18 -20 -22 -24 20 50 100 200 500 Hz Tone controls Independent, 3-band TONE controls are provided for each channel. The Low-Mid cutoff is 300 Hz. The Mid-High cutoff is 4 kHz. These Tone controls are enhanced, 2nd-order filters. The HIGH and LOW filters are shelving. Phase shift is zero degrees with the controls at their center detent. Only the A-channel Tone controls are active in 10-BAND mode. +10 Low +6, Mid ‘0’, Hi +6 Low ‘0’, Mid +6, Hi ‘0’ +5 d b u 0 -5 -10 -15 -20 -25 Low Off, Mid ‘0’, Hi Off -30 -35 -40 Low ‘0’, Mid Off, Hi ‘0’ 20 50 100 200 500 Hz 1k 2k 5k 10k 20k 20 50 100 200 500 Hz 1k 2k 5k 10k 20k +10 Cut Filters 2nd-order Butterworth LOW- and HIGHCUT FILTERS are provided for each channel. The range of the LOW-CUT Filter is 15 Hz to 240 Hz. The range of the HIGH-CUT Filter is 5 kHz to 20 kHz. Only the A-channel controls are active in 10-BAND mode. Manual- +5 d b u 0 -5 -10 -15 -20 -25 -30 -35 -40 In and Out Level controls LEVEL controls serve three purposes, with the assistance of the In and Out Meters: 1. Adjust the IN signal level for good headroom and signal-to-noise. 2. Adjust the OUT signal level to compensate for changes in signal level due to filter boost/cut settings. 3. Adjust sensitivity. The operation of the OUT LEVEL control is reversed from the IN LEVEL. Pushing the control up reduces gain. Pushing the control down increases the gain. To easily adjust sensitivity without affecting the output signal level, grasp the IN and OUT controls and move them together. Only the A-channel IN and OUT LEVELs are active in 10-BAND mode. In and Out Meters IN and OUT Meters are peak responding and indicate signal level in dBu. Peak-dBu is held and displayed for 2 seconds. Attack is instantaneous. Decay is 500 ms for a 20 dB step. A and B meters remain active in linked 10-band mode. EQ Bypass BYPASS switches have two modes of operation. If the rear panel switch is set to BYPASS ALL, all filters and level controls are bypassed. If this switch is set to BYPASS FILTERS, only the filters are bypassed. Filters include Parametric, Tone and Cut. An automatic relay bypass hardwires the Inputs to the Outputs when the POWER is off. BYPASS ALL FILTERS (rear panel switch) A / B control switches A / B switches determine which set of controls is used by channel A and channel B. There is a 100 ms mute to allow the filters to settle when the A/B control switch is changed. The only control not affected by the A / B switches is BYPASS. A / B control switches allow: • Independent, dual mono operation • A/B setting comparison • 5-Band linked stereo operation (A or B controls affect both channels) • Two “analog memories” See the Applications section for example uses of the A / B switches. 10-Band mode / 5-Band mode In 5-BAND mode, the PEQ 55 provides two independent 5-band parametric equalizers. A or B controls may be used to control each channel as described above. In 10-BAND mode, both channels are stereo linked and operation is as follows: 1. All 10 filters affect both A and B Outputs, permitting mono or stereo linked operation. 2. Meters remain independent and active for both channels. 3. Channel A and B BYPASS switches remain active. 4. A1 LOW SHELF and B5 HIGH SHELF modes are available. (A5 high-shelf and B1 low-shelf filter modes are disabled.) 5. Channel A TONE, CUT FILTERS and LEVEL controls are active. (Channel B tone, cut-filter and level controls are disabled.) 6. A / B control switches are inactive. 7. The Outputs mute for 200 ms when switched between 10-BAND and 5-BAND modes.

FILTERS Channel A and B INPUTS Plug the outputs of the mixer or other source to these Inputs. Choose only one type of connector — the ¼" TRS, XLR, and Euroblock do not sum. Note: In agreement with IEC and AES/ANSI standards, wiring convention is pin 2 positive, pin 3 is negative (return), pin 1 is shield chassis ground. Refer to the Sound Sytem Interconnection RaneNote, supplied with this manual, for correct wiring to other connectors or unbalanced devices. Channel A and B OUTPUTS Connect these to the Inputs of an amplifier or mixer. The Outputs may be used simultaneously to drive different devices at once. All Outputs are balanced and follow the same “pin 2 hot” convention as the Inputs. Power connector The PEQ 55 uses a universal internal switching power supply that accepts 100 to 240 VAC at 50 to 60 Hz, allowing it to work in most countries. The line cord attaches to a standard IEC appliance inlet. A US line cord is shipped with each unit.
