POWER CONDITIONING: AC power conditioners and AC mains power
cables are a common accessory in many high performance audio and
video systems and can be used to improve the quality of reproduction
in certain instances. We have tried to provide the best possible basic
power cord with the Model 501, however many users wish to experiment
with more expensive and esoteric accessories. As we have never found
the perfect or universal power conditioner or cable, it is not possible to
recommend any particular type or brand for use with the Model 501 Mono
Amplifier. Please use your dealer’s help and knowledge as a resource to
select the proper accessories for your individual system needs.
NOTE: Due to the exceptionally low power consumption rating of the Model 501, it is
recommended that the unit not be disconnected from AC mains unless it is to be moved or
reinstalled in another location. It is recommended that the amplifier simply be left on when
the unit is not in use.
WARNING: Serious damage to internal circuitry can occur if improperly wired or
unapproved AC power cords are used. Your dealer can be a helpful resource for
selecting the proper accessories for your needs. Also, if the unit is plugged into a voltage
different from the range listed on the back panel, it will result in serious damage and will
void the warranty.
(6) 12V REMOTE TRIGGER: A 1/8” (3.5 mm) mini-plug connector
is provided on the rear panel for remotely switching the amplifier
between Operational and Standby modes. When connected to
another component with the proper circuitry, the amplifier standby
function can be turned ON and OFF remotely in a custom installation,
theater, or automated system setup. (See FIGURE 1)

requirements
NOTE: Please be aware that the remote feature simply places the
amplifier in standby mode and does not disconnect the unit from
power or AC mains.
NOTE: If a 12V DC switching source is not available, then a short
circuit between the “tip” and “sleeve” of the 1/8” mini-plug connector
will place the amplifier into the STANDBY MODE. Removing the
short circuit will return the amplifier to the OPERATIONAL MODE.
