OPERATORS MANUAL PE 15
PARAMETRIC EQUALIZER
QUICK START
If all else fails, read the manual. Yeah, yeah. But nothing is going to fail and you, being one smart cookie, don’t need
to read the stupid manual. But you should read this section just to cover your affairs. So, quickly, here goes.
The PE 15 has few hidden gotchas. One of these may be the shelving feature of Bands 1 and 5. Remember that
pulling on the bandwidth (BW) knob causes it to come forward with a positive click, indicating the Shelf Mode is active.
Use Shelving Bands 1 and 5 like Bass and Treble tone controls, where you want control over the whole top or bottom
ends of the spectrum.
Hook-up is simple. The PE 15 accepts all combinations of balanced or unbalanced, XLR, ¼" TRS or TS connectors.
However, note the INPUT connectors are wired in parallel and may not be used together. Use only one at a time. They
will not function as a summing type of Input for two different sources, but they may be used in a daisy chain fashion
to feed other units. On the other hand (to randomly pick a hackneyed expression), you may use the paralleled OUTPUTs
to drive two destinations.
Never connect anything except a Rane approved AC power supply to the thing that looks like a red telephone jack
on the rear of the PE 15.
WEAR PARTS: This product contains no wear parts.

FRONT PANEL DESCRIPTION
POWER switch: The key to life in any electronic device. This switch allows power to flow from the source to the very soul
of the PE 15, thereby empowering all its vital functions.
POWER indicator: When this yellow LED is lit, the unit is ready to serve.
OVERLOAD indicator: illuminates red whenever the signal level at the Input, Output, or any of the five equalizer stages
comes within 3-4 dB of clipping.
MASTER LEVEL control: Full counterclockwise rotation of this control provides full Input attenuation; full clockwise
rotation yields 20 dB of gain through the unit. Unity gain is approximately 12:00, (Central Daylight Time).
Overall BYPASS switch: Engaging this pushbutton provides a complete hard-wire bypass of the PE 15, including signal
ground. In the out position, the Input to the unit is processed through all of the active electronics. This is a passive control
requiring no power to operate.
Overall BYPASS indicator: illuminates red when the unit is in the BYPASS mode created by .
BANDWIDTH controls (Q): Full counterclockwise rotation yields a bandwidth of 1/30 octave (Q=43) in the respective
filter, while full clockwise rotation gives a 1.5 octave (Q=0.9) bandwidth. (Pulling this control to the out position on Bands 1
and 5 switches the filters to their Shelf Mode.)
Filter LEVEL controls: The center detent position guarantees flat response through the respective filter due to its grounded
center-tap. Full clockwise rotation delivers +15 dB of boost, while full counterclockwise rotation yields -20 dB of cut.
FREQUENCY sweep controls: set the center frequency of the filter band (or the Turnover Frequency for Shelf Mode).
Available sweep range is approximately four octaves.
Filter BYPASS switches: Each of the five filter BYPASS switches disables the respective filter providing instant compari-
son between flat response and equalized response.
Filter BYPASS LED: illuminates when the band is in BYPASS created by .
