INSPECTION Your HPA-4 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 that 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.

Parts of the unit can become very warm during use. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12" or 30cm). Do not place the HPA-4 on high temperature devices such as power amplifiers, etc. , or the unit may overheat in operation. Also, do not place the unit on speakers as this may cause them to move and/or fall due to speaker vibrations. 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. POWER CONNECTION The HPA-4 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the back panel is proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information 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. When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC power source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with headphones. 4 FRONT & REAR CONNECTIONS (5) (4) (6) FRONT PANEL (1) (2) REAR PANEL (8) (9) (7) (3) FRONT PANEL (1) STEREO HEADPHONE OUTPUTS Four stereo 1/4" output jacks for connecting four stereo headphones (2) DIRECT LINE DISTRIBUTION OUTPUTS Four stereo 1/4" line level output jacks for use for line distribution REAR PANEL (3) AUDIO INPUTS Four stereo-pair balanced, line level 1/4" TRS jacks for 4 stereo (L & R) input signals.
