These five equalizer models are each designed for mounting in a standard 19" equipment rack or one of the many rack type portable cases available on the market. The units are either single rack (1.75") or double rack (3.5") as noted. All five models are 8.66 inches deep. Install the equalizer in a rack with the rack screws provided. Route the A.C. power cord to a convenient power outlet away from audio lines. The unit may be turned on and off from the front panel power switch or a master equipment power switch. Since the unit draws a relatively small amount of current during idle, the unit may be left on continuously. NADY AUDIO equalizers do not generate an unduly large amount of heat and do not need to be specially ventilated or cooled. The units should not be subjected, however, to high heat environments. Although the unit’s chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF and EMI should be avoided. Input/Output Connections The 1/4" phone jack, RCA 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, For unbalanced operation, wire the connectors as follows: wire the connectors as follows: Power Connection Each of these five NADY AUDIO graphic equalizers is designed for operation from 120-240 volts, 50-60 Hz AC supplies. 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. 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: 120V, 60 Hz For other areas, please check with local authorities. VOLTAGE SELECTOR 115V 230V 120V 240V 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. 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.
