Installation

INSTALLATION

To ensure years of enjoyment from your NADY AUDIO graphic equalizer, please read and understand this manual thoroughly before using the unit.

These three equalizer models are each designed for mounting in a standard 19” equipment rack or one of the many rack type por- table cases available on the market. The units are either 1u single rack (1.75”) or 2u double rack (3.5”) as noted. All three models are 5 inches deep.

Install the equalizer in a rack with rack screws (not included). 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 is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF and EMI should be avoided.

Paralleling inputs and outputs may be accomplished by using any of the 2 connectors.

POWER CONNECTION

Each of these three NADY AUDIO graphic equalizers is designed for operation with 105-130 volts AC at 60Hz 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 before connecting the instrument to power sources.

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.

Protecting your NADY AUDIO Graphic Equalizer:

•Use only a household AC power source. Never use a DC

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.
