Reference Manual
3.4 AC Power Requirements
All 120-VAC, 60-Hz North American units have a NEMA
5-15 AC plug. These units include a 16-gauge cord.
To
meet full regulatory system compliance, these cords
must be plugged into a local, cabinet-mounted, com-
mercial-grade electrical outlet box. “Extension”
cords are not recommended or adequate.
Use an isolated wall outlet,whenever possible, with the
correct voltage and adequate current. Voltages greater
than 10% above the specified AC mains voltage for the
amplifier may damage the ±15 volt regulator, filter ca-
pacitors and output transistors. See Section 7 for power
requirements under various conditions.
All specifications in this manual were measured using
120-VAC, 60-Hz power unless otherwise noted. Speci-
fications are derived using a mains voltage that is accu-
rate to within 0.5% with THD less than 1.0% under all
testing conditions. Performance variations can occur at
other AC voltages and line frequencies. In addition, line
regulation problems will directly affect the output power
available from the amplifier.
Use Good Connectors
1. To prevent possible short circuits, do not ex-
pose the loudspeaker cable connectors.
2. Do not use connectors that might accidentally
tie two channels together when
making or breaking connections
(for example, a standard
three-wire stereo phone plug).
3. Connectors that can be
plugged into AC power recep-
tacles should never be used.
4. Connectors with low cur-
rent-carrying capacity should
not be used.
5. Connectors with any tendency to short should
never be used.
