1. OUI MIKER OPERATING GUIDE CAUTION TO PREVENT ELECTRICAL SHOCK OR FIRE HAZARD DO NOT EXPOSE THIS INSTRUMENT TO RAIN OR MOISTURE BEFORE USING THIS INSTRUMENT READ BACK COVER FOR FURTHER WARNINGS 4562 EE 6C1R 3 TRODUCTION The system you have purchased is a very portable package with the flexibility of mixers twice the size at twice the price The 601R features six channels excellent 3 band equalization and rack mount versatility Rack mountable mixers have a special place in sound reinforcement applications and many times no other type product will suffice The 601R requires a very low profile vertical mounting space and is exceptionally thin front to back These dimensions are critical as rack space is usually a premium consideration The input circuitry has tremendous dynamic range and will handle sound reinforcement applications with ease As you read the enclosed literature please try to learn as much as possible about the product so your job of sound reproduction will be easier and the results will be an overall improved performance The person doing sound or installing sound systems is actually an extension of the performance and should master the sound equipment just as a musician masters his her instrument INPUT GAIN CONTROL The input gain control determines the sensitivity of each individual channel It should be adjusted accordingly to each instrument or vocal that is being patched2.

4. Having the monitor send with pre capability is absolutely vital to avoid feedback of the monitor system when various channel adjustments are made to the outfront system HIGH FREQUENCY EQ CONTROL The high frequency control is capable of 15 dB boost or cut at 8 KHz with a shelving characteristic a S 2 sloping down to the crossover point High frequency boost is obtained with a clockwise rotation of this 2 8 control and counter clockwise rotation results in a cutting of the high frequencies Flat response is A obtained in the center 12 00 position This flat 12 00 position is an excellent placeto begin tuning the system so that with different rooms and concert halls you will be able to determine what degree of 373 equalization is needed and then adjust accordingly 12 MID FREQUENCY EQ CONTROL The mid control is capable of 15 dB boost or cut at 600 Hz with a peak notch type filter response This middle EQ circuit enables control over the vital mid range frequencies The action of this middle filter is somewhat different than the high and low EQ since it is of the peaking and notching type This type of filter response is necessary to avoid undue interaction with the high and low equalizers Caution must be exercised in order to avoid overboosting or overcutting the mid range Experience has proven that for most applications a very slight mid range cut tends to produce a tight and well defined sound Generally larger am

11. into this system The operator must adjust the input gain so that overload clipping is avoided at the input A very strong signal coming into the mixer would require a fairly low setting of the input gain control and obviously a very weak signal will require a fairly high setting of this control Proper adjustment of the input gain control may be easily E by setting up the highest expected input signal level and adjusting the input gain so that o clipping or distortion is heard from the amp speaker system After this mixer has been used several tipica the operator will have a very good idea of the signal levels encountered and will be able to set up the input sensitivity with no difficulty Please be aware that different types of microphones will have different output levels and different performers will get widely varying signals from microphones depending on the strength of their voices and or their basic microphone technique MONITOR SEND CONTROL The monitor send control is the channel mixing element for determining the all important monitor mix The signal for the monitor send is obtained right after the input preamp and before the channel EQ This type control is referred to as a pre monitor send i e it is before or pre to the channel equalization and channel level control This makes the control independent of all equalization and channel level adjustments Alterations to channel EQ will not affect the equalization of the monitor system
