1. XLR amp 14 OUTPUT jacks These jacks are active balanced Ouputs The 14 TRS tip is signal positive the ring is signal negative and the sleeve is signal ground The 3 pin wiring is per IEC ANSI AES standards pin 1 signal ground pin 2 positive and pin 3 negative These jacks parallel each other and unlike the Input may deliver two Ouputs simultaneously PATCH I O connector This 14 TRS jack provides an unbalanced I mpu on its tip and an unbalanced O Output on its ring This is designed for use with tip send ring return effect loops found on many mixing consoles providing an easy means for patching the unit into effect loops using only a single 14 TRS 2 conductor patch cable Caution Use either the PATCH I O or the INPUT and OUTPUT connectors do not use both These are not summing Inputs Remote POWER supply input This unit is supplied from the factory with a model RS 1 Remote AC Power Supply suitable for connection to this jack This unit requires an 18 volt AC center tapped transformer only This is not a telephone jack Never use a power supply other than the one supplied or a Rane approved replacement Chassis ground point A 6 32 screw used for chassis grounding purposes See the note below CHASSIS GROUNDING After hooking up your system if it exhibits excessive hum or buzzing an incompatibility in the grounding configuration between units exits Ha Now you earn your money now you pay the piper Now you must2. panel as possible without lighting the OL indicator yields the best signal to noise performance LOW amp HIGH CUT FILTER controls set the corner frequencies of the band limiting filters The frequencies shown represent the 3 dB points for each filter When the sliders are located at their bottom most positions the filters are at their lowest and high est extremes and thus effectively bypassed FILTER LEVEL control The center detent position guarantees flat response through the respective filter due to its grounded center tap design Full clockwise rotation yields 12 dB of boost while full counterclockwise rotation gives you 15 dB of cut FREQUENCY multiplier switch The markings on this three position slide switch indicate the factor by which the calibrations of the Frequency sweep control are multiplied For instance if the range switch is in the x0 1 position and the FREQUEN CY control is at 460 then the actual center frequency of the filter is 46 Hz Operation of this switch in conjunction with the FREQUENCY control yields a range of 10 Hz to 20 kHz for each band FREQUENCY sweep control increases the center frequency of the filter band as it is turned clockwise It is calibrated from 100 to 2k The exact frequency is determined by multiplying the value indicated by the frequency multiplier switch Individual band BYPASS switch amp indicator Each of the five filter BYPASS switches disable

6. d systems the most common loca tion to insert a parametric equalizer is immediately preceding the active crossover or power amplifier This provides the means to correct loudspeaker deficiencies required in any system for high quality reproduction Many systems employ both a graphic and parametric equalizer connected in series The graphic finds use in personal preference or program equalization while the paramet ric helps with sources loudspeaker compensation and feedback control In these situations the order of placement is not critical however the PE 17 does feature servo cross coupled balanced Outputs which allows use in installations requiring very long cable runs between the equalizers and the power amplifiers or crossovers The 4 TRS and XLR Input connectors are wired in parallel and are actively balanced These Inputs are provided primarily to give the user a choice between two types of connectors They will not function as a summing type of input for two different sources For further information on this subject please consult the Rane Note Why Not Wye available from the Rane website The two Inputs may be used in a daisy chain application where the Input to the PE 17 also must feed another piece of equipment The Outputs of the PE 17 offer the same connector choice They also are wired in parallel and are actively balanced How ever both Outputs may be used simultaneously if desired All XLR connectors used by Rane are
