Manley MOVING COIL & MOVING MAGNET PHONOGRAPH PREAMPILFIER - Manual (Page 4)

INSTALLATION PRECAUTIONS
a) Avoid locating the preamp where it will be exposed to direct sunlight, excessive
humidity, dust or moisture. Extreme environments may temporarily or permanently
degrade preamp performance.
b) Keep the preamp housing away from sources of strong magnetic field radiation, such
as large video display CRTs, large power lines or power/audio transformers in nearby
equipment. Keep in mind that the tiniest disturbance to sensitive signal cables will be
amplified many hundreds or thousands of times.
c) Locate the preamp away from heat-radiating sources, such as other large amps, or
space-heating equipment.
d) Make sure the preamp and power supply is switched off before making any system
connections.
e) Dissipate any static electric charge build-up on your body by touching the enclosure
before making or changing any system connections. The preamp electronics are fairly
robust as far as immunity to damage from static charge is concerned, but total immunity
cannot be had without unacceptable compromise of audio performance.
Be careful to feed only low-level phono cartridge signals to the preamp input connectors.
Sustained line-level signals above 15 volts peak may cause damage to sensitive MC input
stages even when the preamp is in the standby mode or when the power is off.
AC VOLTAGE SELECTION
Before powering your Chinook check that the Voltage corresponds to your local supply. This
is labeled on the serial badge. i.e if your supply is 120V the serial badge must state 120V AC.
If the marked voltage does not correspond do not power the unit and consult your dealer
immediately.
The Chinook can be factory ordered in a 120 or 240 Volt configuration. Consult your dealer
if you need to change the operating voltage, as this is not a user-modifiable feature.
