User manual RANE PEQ 55

[. . . ] 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. 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. [. . . ] 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. Settings below 25 Hz default to 25 Hz. +14 +12 +10 +8 +6 +4 +2 d0 B u -2 -4 -6 -8 -10 -12 -14 -16 -18 -20 -22 -24 20 50 100 200 500 Hz 1k 2k 5k 10k 20k 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. 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 1k 2k 5k 10k 20k Tone controls Independent, 3-band TONE controls are provided for each channel.

Adjust the OUT signal level to compensate for changes in signal level due to filter boost/cut settings. To easily adjust sensitivity without affecting the output signal level, grasp the IN and OUT controls and move them together. In and Out Meters IN and OUT Meters are peak responding and indicate signal level in dBu. 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. 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. 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. [. . . ] 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. Output B uses the B set of controls. EQ B 5-BAND IN -12 -6 -3 0 +3 +6 +12 OL OUT A If your mixer uses TRS Insert jacks (unbalanced), we recommend using cable wired as shown below.
