Power Requirements

The Portico 5045 dissipates about 15 watts, which means that it will get warm in use.  Each Portico 5045 

module has an internal high quality DC to DC converter that provides carefully stabilized and filtered 
+/– 17.5 VDC for the amplifiers. The meticulous audio quality of your Portico is protected by the internal 

converter and does not depend primarily on the external mains power supply. The input is protected 
from reverse polarity. The connector center pin must be positive. 

One of the advantages of the Portico method of powering equipment is that external power units will 
work from almost any of the very wide range of mains supply voltages and frequencies that are found 
world-wide. While many different types of mains power wall sockets are found in different countries, 
Portico 5045 module power units leave the factory with standard US power cords. If required, any 
suitable connecting cord may be substituted that does not defeat the 3rd pin grounding of the AC cord. 
Avoid using a mains power outlet that is on the same circuit as air conditioning or other equipment that 
regularly switches on and off. Unplug your Portico power units during a thunder storm or if it will be 
unused for a long period.
