Nady Systems PEQ-5B Installation, For balanced connection Wire the connectors as follows

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 fac- tory 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" equip- ment rack or one of the many rack type portable cases avail- able 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 spe- cially ventilated or cooled. The unit should not be subjected, however, to high heat environments. Although the unit's chas- sis is shielded against radio frequency (RF) and electromag- netic 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 out- puts 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.

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 combina-

For balanced connection,

wire the connectors as follows:

XLR JACK	CONNECTION
PIN 1	GROUND
	(optional, use as shielding to prevent hum)
PIN 2	HIGH (+)
	LOW (-)
PIN 3
1/4” TRS JACK	CONNECTION
TIP	HIGH (+)
RING	LOW (-)
SLEEVE	GROUND
	(optional, use as shielding to prevent hum)

For unbalanced operation,

wire the connectors as follows:

XLR JACK	CONNECTION
PIN 1	GROUND
PIN 2	HIGH (+)
1/4” TRS JACK	CONNECTION
TIP	HIGH (+)
SLEEVE	GROUND

tions 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.
