[. . . ] Check to see that the unit is set to the voltage for your area by referring to the table below: Europe (except UK): 230V, 50Hz UK and Australia: 240V, 50Hz USA and Canada: 115V, 60 Hz For other areas, please check with local authorities. If the voltage selector is not set for your area: Confirm that the power cord is not plugged into a wall outlet. Move the voltage selector switch with a small screwdriver so that the marker is set to the voltage for your area. PRECAUTIONS Protecting yourself from electric shock: · Never touch the plug with wet hands. · Always pull out by the plug and never the cord. · Only let a qualified professional repair the equipment. An unauthorized person might touch the internal parts and receive a serious electric shock. Note: Removing the chassis screws and opening the unit will automatically void your warranty. · Never allow a child to put anything into the equipment. INPUT/OUTPUT CONNECTIONS The 1/4" phone jack and XLR connector inputs and outputs can be used for balanced and unbalanced connections. CAUTION: Using more than one connector at a time for the INPUT/OUTPUT pair could unbalance balanced lines, cause phase cancellation, short a conductor to ground, or cause damage to the other equipment connected to the equalizer. For balanced connection, wire the connectors as follows: For unbalanced operation, wire the connectors as follows: Protecting your NADY AUDIO Graphic Equalizer: · Use only a household AC power source. · If water is spilled on or in the unit, unplug it and call for service. · Make sure that the equipment is well ventilated and away from direct sunlight · Avoid damage to the internal circuits and the external surface by keeping the unit away from sources of high heat. · Avoid using spray type insecticide or solvents near the equipment. It can damage the finish an might ignite suddenly · To avoid damaging the finish, never use denatured alcohol, paint thinner or other similar chemicals to clean the equipment. · Place the unit on a flat and solid surface or in a rack. · To enjoy your NADY AUDIO graphic equalizer for a long time, please read this owner's manual thoroughly. Paralleling inputs and outputs may be accomplished by using any of the 3 connectors. Note: The 1/4" TRS are normally used for this function. POWER CONNECTION Each of these three NADY AUDIO graphic equalizers is designed for operation with 105-130 volts AC at 60Hz or 210-240 volts AC at 50Hz power sources . Power requirements for electrical equipment differ from area to area. In new installations and portable sound systems, or any situation in which the AC power is in question, it is wise to confirm the voltage and select the appropriate line voltage switch before connecting the instrument to power sources. 5 FRONT PANEL CONTROLS & CONNECTIONS GEQ 131 234 GEQ 215 5 6 1 1 GEQ 231 6 2 345 2 34 5 6 1 1. Power Switch To turn the equalizer ON or OFF, press the upper or lower portion of this button. The internal LED indicator will light when the unit is on. CAUTION: Always turn on your equalizer BEFORE your power amplifiers are turned on, and always turn off your equalizer AFTER your power amplifiers have been turned off to avoid any turn on/off transient noise. Gain Control The Gain control allows adjustment between OFF (center detent) and +/-12dB. [. . . ] Put the equalizer in an effects send and return it to the MIX bus. Create an artificial stereo by splitting a monaural signal and equalizing the split signals differently, then panning one equalized signal to the right and the other signal to the left. Shape the sound by changing the frequency response of the track. Special effects, like a telephone sound, can be created by cutting off the LOW end to 200Hz and the HIGH end to 6KHz. 8 SPECIFICATIONS EQUALIZER: Equalizer Control Bands 1X31, 1/3 Octave ISO Spacing From 20Hz to 20KHz 2X31, 1/3 Octave ISO Spacing From 20Hz to 20KHz 2X15, 2/3 Octave ISO Spacing From 25Hz to 16KHz Filter Type Constant Q Slider Travel 20mm (Center Detent) for GEQ 131/215/231 Level Control Range +/-12dB Channel Separation 60dB (1KHz) Line Voltage 100-130V AC, 50/60Hz 200-240V AC, 50Hz Power Consumption Maximum: 15 watts SIZE: 19"W X 3. 5"H X 5"D (2U) (48. 2cm X 8. 8cm X 12. 7cm) For 231 19"W X 1. 75"H X 8. 66"D (1U) (48. 2cm X 4. 4cm X 12. 7cm) For GEQ 131/215 INPUTS: Type Active Balanced/Unbalanced Connectors 3-Pin XLR, 1/4" TRS (Balanced), RCA (Unbalanced) Impedance 40K Ohms Balanced; 20K Ohms Unbalanced Maximum Level 28dBV WEIGHT: 4. 15lbs.
