Operating Voltage
& Frequency
The Digital Surround Decoder is set at the factory (internally) for 100V, 120V,
220V, 230V, or 240V and either 50 or 60 Hz AC mains operation, as appropriate
for the country in which it is to be sold. (230V/50Hz only in European Union
countries, in compliance with CE regulations.) Neither the voltage nor the line
frequency setting may be changed by the user.
Make sure that the label on the rear panel of the Digital Surround Decoder
(above the AC input receptacle) indicates the correct AC operating voltage for
your location. Attempting to operate the Digital Surround Decoder at an incorrect
voltage can damage the unit.
Warning: Neither the voltage nor the line frequency settings of your
Digital Surround Decoder may be changed by the user. There
are no user-serviceable parts within the unit. Please refer any
problems to an authorized Proceed service center.
If the AC mains voltage or frequency indicated on your Digital Surround Decoder
is incorrect, please contact your local, authorized Proceed dealer or distributor.
The Digital Surround Decoder can easily be powered by a normal 15-ampere AC
mains line. If other devices are also powered from the same AC line, their addi-
tional power consumption should be taken into account.
warm up/break-in period Although your Proceed Digital Surround Decoder delivers outstanding perfor-
mance straight out of the box, you should expect to hear it continue to improve
as it reaches its normal operating temperatures and its various components
“break-in.” It has been our experience that the greatest changes occur within the
first 300 hours as the PDSD reaches thermal equilibrium and the capacitors fully
form. After this initial break-in period, the performance of your new product
should remain quite consistent for years to come.
The only exception to this rule is if power is removed from the unit for an ex-
tended period of time, allowing it to cool down. Depending on the degree of
cooling involved, you should expect a brief warm-up period before the Digital
Surround Decoder’s sound quality is at its best. Unless your Digital Surround De-
coder was allowed to become quite chilled, subsequent thermal re-stabilization
should not take long.
