The peerless finish, build quality,
ergonomics and pride of owner-
ship that contribute to the totality
of the Gryphon concept can only
be fully understood and appreci-
ated up close and in person. 

Rasmussen’s background in fine
arts and industrial design gives
every Gryphon product a distinc-
tive, luxuriant finish which arises
organically out of the audio cir-
cuit design and the user inter-
face for a truly unique integration
of form and function.

Manufacture and
Assembly

At our laboratories and manufac-
turing facilities in Denmark, we
maintain full control over every
aspect of development and pro-
duction, and the members of our
conscientious staff diligently fol-
low each Gryphon model from
initial concept to early prototype,
through to final quality control.

Printed circuit boards are
assembled by a supplier of pre-
cision military and medical
equipment with strict standards
of quality control and pre-inspec-
tion of components. Chassis
parts are manufactured by a
specialist chosen solely for the
outstanding quality of workman-

ship. In every aspect of every
Gryphon product, the same
stringent standards of excel-
lence apply.

Following a 48-hour burn-in,
each product is tested again,
before being subjected to
Gryphon’s custom-developed
transport simulator which simu-
lates the inevitable shaking that
a product will encounter in tran-
sit. The product is placed on top
of a very large loudspeaker
which plays a special CD with
low frequencies which simulate
the vibrations of an airplane.
Each unit “travels” the equivalent
of 40 round trips from Denmark
to Australia before leaving the
factory.

AC Voltage

Your Gryphon unit is especially
made for the AC voltage of the
country to which it has been
shipped. If the voltage has been
changed, the warranty is void
and the product may be unsafe
or malfunction.

Correct AC polarity contributes
greatly to optimum performance.
If you are not using a three-pin,
non-reversible power plug,
please experiment with the ori-
entation of the plug for optimum
performance.
