External Power 
About Power Supplies 
An external power supply conforming to the specifications listed in the following “Power Supply 
Specifications
” section must be used to guarantee that published SoundPals performance 
figures are met.  Any power supply meeting these specifications will supply adequate power for a 
single SoundPals module.  Although the specification is written for power supplies running from 
AC line inputs, DC (battery) sources may be used if they meet all of the listed requirements. 
CE Compliance 
For CE compliance, the power supply that you use must comply with the following requirements: 
•  Low Voltage Directive 73/23/EEC 
•  EMC Directive 89/336/EEC 
•  EMC Directive 93/68/EEC 
•  The connector locking ring must be tight. 
Portable Power Sources 
For portable SoundPals power sources, sealed lead-acid, nickel cadmium or alkaline primary 
batteries may be used.  However, the maximum voltage must not exceed 8.6 volts, and a 
minimum of 5.6 volts is required for normal operation.  Maximum current drain will be 215mA.   
Power Supply Specifications 
The following specifications must be met over all anticipated operating conditions including AC 
power line range, temperature range, etc.
