The Garrard
401 which operates at three standard speed is produced to the highest technical specification to meet the most
exacting requirements of radio, television and recording studios as well as for
high-fidelity enthusiasts.
Styled by
one of Britain's leading designers it presents an elegant appearance in
metallescent charcoal with chrome relief. The balanced, machined turntable is
an aluminium, gravity casting weighing approximately 6 lb.
Accurately
spaced, gear-cut stroboscopic markings on the periphery of the turntable are
illuminated by a high-intensity neon lamp situated in the rigid aluminium base
plate.
This is a
unique feature of the 401 and enables the user visually to check that the
turntable is running at exactly the correct speed.
Fine speed
adjustment is achieved by means of an eddy current brake; a control on the unit
base allowing the speed to be veried by plus or minus 3 per cent.
The high -
and low-range (110 -125 V and 220-250 V) shaded-pole induction motor, encased
in a heavy iron casting to provide full magnetic screening, is isolated from
the base plate by six tensioned springs. This provides an effective vibration
barrier between the motor and the rest of the unit. The spindle is machined
from a high grade of steel which is then hardened, tempered, ground and
superfinished.
A
double-pole switch is used for the power supply to the motor and is fully
supressed. Each unit undergoes the most rigorous inspection and test, and the
final performance figures are recorded on an individual test report which
accompanies the unit.
Every
Gerrard Unit is 100% inspected on the very latest electronic test equipment to
make sure that it conforms to the high standard of quality and reliability for
which Garrard are world-wide renowed.
All Garrard
units are wired for stereo reproduction (also suitable for mono) and all
automatic turntables have facilities for manual (single record) operation.
Each model
has been specially designed to meet specific and exacting requirements giving a
complete range from the highest quality transcription tuntable to the popular
priced automatic and single record-playing units.
Leading
designers keep Garrard to the forefront in contemporary styling.
Special
durable finishes are used, making every Garrard unit suitable for tropical
conditions.
Each unit is
supplied with template (giving all dimensions), transit or fixing screws,
installation and operating instructions.
Units not
supplied with pickup cartridge should be fitted with the cartridge of your
choice. For advice, consult your dealer.
All Garrard
models are designed to play records conforming to I.E.C. Publication 98,
BS1928;1965, and equivalent national standards.
