To ensure years of enjoyment from your NADY AUDIO SPM-4250 powered mixer, please read and understand this
manual thoroughly before using the unit.
1. INSPECTION
Your NADY AUDIO SPM-4250 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.
[Please note: Nady Systems is not responsible for shipping damage. If your unit is damaged, do not return to Nady, but
notify your dealer and the shipping company (if shipped to you) immediately to make a claim. Such claims must be made
by the consignee in a timely manner.]
2. SETUP AND OPERATION
Parts of the unit can become very warm during use. This is normal during operation. Care should be taken to ensure that
there is enough space around the unit for cooling. Also, do not place the SPM-4250 on high temperature devices such as
power amplifiers, etc., or the unit may overheat in operation.
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.
Please make sure that the power unit supplied is marked for the correct voltage in your area (120VAC/60 Hz or 230VAC/
50 Hz). 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 use the appropriate
power supply unit before connecting it to power sources.
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.
Power up the unit as noted on page 8.
