ATTENTION: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR An equilateral triangle enclosing an exclamation point is intended to alert the user to the presence of important operating and service instructions in the literature enclosed with this unit. IMPORTANT SAFETY INSTRUCTIONS When using electronic device, basic precautions should always be taken, including the following: 1. Read all instructions before using the product. 2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming pool, etc.). 3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling. 4. This product, in combination with headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an audiologist. 5. The product should be positioned so that proper ventilation is maintained. 6. The product should be located away from heat sources such as radiators, heat vents, or other devices (including amplifiers) that produce heat. 7. The product should be connected to a power supply only of the type described in the operating instructions or as marked on the product. Replace the fuse only with one of the specified type, size, and correct rating. 8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other devices so that the outlet's or extension cord's power rating is exceeded, and (3) never be left plugged into the outlet when not being used for a long period of time. 9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure's openings. 10. The product should be serviced by qualified service personnel if: A. The power supply cord or the plug has been damaged. B. Objects have fallen into, or liquid has been spilled onto the product. C. The product has been exposed to rain. D. The product does not appear to operate normally or exhibits a marked change in performance. E. The product has been dropped, or the enclosure damaged. 11. Do not attempt to service the product beyond what is described in the user-maintenance instructions. All other servicing should be referred to qualified service personnel. 3 FEATURES PEQ-5B Parametric Equalizer With its advanced state-of-the-art features and versatile utility, the PEQ-5B five-band parametric equalizer is a rugged workhorse, designed for long-haul reliability in the studio and live sound reinforcement applications. ·15dB boost/cut per band · Constant-Q, state-variable filter circuitry for precision control of tone coloration · Parallel phase filters for minimal phase shifting · Tunable high and low-cut filters for removing floor rumble, tape hiss, etc.. · Each band independently switchable and adjustable in bandwidth (.03 to 2 octaves wide), allowing a range of adjustment from tight notching to extreme boost/attenuation by band overlapping · Constant-Q state variable filters for maximum filter stability · Servo-balanced XLR and 1/4" TRS inputs and outputs · Bypass switches on each channel with LED status indicators · Highly accurate 12-segment LED switchable Input/Output meter · Failsafe relay with auto-bypass during power failure · Single rack space (1U) rugged metal housing for reliability · IEC power cord socket for AC operation with internal shielded power supply, external fuse, and ~115V (60Hz) / ~230V (50Hz) AC select switch 4 INSTALLATION To ensure years of enjoyment from your NADY AUDIO PEQ-5B Parametric Equalizer, please read and understand this manual thoroughly before using the unit. 1. Inspection Your NADY AUDIO PEQ-5B was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage which may have occurred in transit. (Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.) 2. Rack Mounting This model is designed for mounting in a standard 19" equipment rack or one of the many rack type portable cases available on the market. The unit fits in a standard 19" single rack (1.75"). Install the equalizer in a rack with the rack screws provided. Please allow at least an additional 4" depth for the connectors on the back panel. 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. The PEQ-5B does not generate an unduly large amount of heat and does not need to be specially ventilated or cooled. The unit 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. 3. Input/Output Connections The 1/4" TRS phone jack and XLR connector inputs and outputs can be used for balanced and unbalanced connections. For balanced connection, wire the connectors as follows: XLR JACK PIN 1 PIN 2 PIN 3 CONNECTION GROUND (optional, use as shielding to prevent hum) 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. 4. Power Connection The PEQ-5B 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. 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. 5. Signal Levels Signal levels from -21dBu to +21dBu are considered normal. Do not directly connect microphones into the equalizer's inputs. Microphones require a pre-amp. 6. Chassis Grounding The PEQ-5B is equipped with a rear panel Ground Screw. This is generally connected with a short piece of wire to the chassis ground shared by the other connected equipment in the rack. If, after setting up your system, the system exhibits excessive hum or buzzing, the problem may be that there is a ground incompatibility between your equalizer the other equipment in the same system. There are several combinations that can be attempted. Note: ALWAYS TURN YOUR AMPLIFIERS DOWN BEFORE CHANGING YOUR GROUNDS AROUND. Try different combinations of lifting ground wires or make sure all chassis are connected to earth ground, either through the A.C. power cord ground or by the front panel rack mount screws. For unbalanced operation, wire the connectors as follows: XLR JACK PIN 1 ...
