POWER NOTICE FOR SAFETY

All british and european countries have a nominal 230v mains power supply which in practice is between 220V and 240V. In the USA the main power supply is nominally 115V and in Japan 100V. This unit is factory set to the correct voltage and this can be checked by looking at the label on the rear panel near the power cable. If the unit is to be used in a country other than that it was shipped to consult your dealer. The unit is suitable for use with mains frequencies of 50-60Hz. As there are no user serviceable components inside the amplifier, and high voltages are present, DO NOT remove the covers! Be sure to make all audio connections to the amplifier before connecting to the mains supply. Do not disconnect the amplifier from the grounded equipment with the mains connector still plugged into the mains supply. Important warning! This Unit Must Be Grounded, Do not Disconnect the Ground Connection! Any sound system should be connected to ground at one point only. If there is more than one connection to earth, a GROUND LOOP can be formed, which allows mains hum to enter the circuitry, sometimes at a high level. If hum occurs in the system consult your dealer.
