Industrial Design - Halcro dm10 Owner's Manual

Industrial design

Product form
The aim when designing the dm8 and dm10
was to create a preamplifier
unmistakably part of the Halcro product family,
but at the same time a component that would
compliment any high-end audio system.
The preamplifier had to sit comfortably within a
contemporary domestic environment, retain
the visual signature of the Halcro family of
products, which differentiates them from
other high-end audio products, and have an
appearance that reflected the high level of
technical innovation. As with other Halcro
products, softer forms and textures are used,
all fasteners are concealed and the heat sinks
are integrated into the external form to
maintain simple, clean lines.
Whilst the unique pillar forms of the power
amplifiers have been carried through to the
preamplifier, proportions have been reworked
to allow this component
freestanding or housed within a standard 19"
shelving system.
Control interface
Knobs and buttons
The volume and input selector knobs use a
unique
that was
mechanism developed to provide a very
subtle and reliable indexing action. The knobs
and buttons are finished in the same soft
textural finish as the pillars.
Display
A high-resolution display was chosen in order
to provide clean simple graphics without the
rough edges associated with displays of
lesser quality. The graphic layout of the display
has been optimized to give prominence to the
functions that are viewed most often. These
include volume levels, balance and input
selection. Functions that are accessed less
often are displayed in smaller type along the
bottom
stereo/mono and in or out-of-phase. The
volume levels for each channel are displayed
side-by-side so that when the levels are not
to be either
equalized the user will easily notice it.
Remote control
When designing the Halcro Remote Control,
we aimed to reflect the quality and forms of
the Halcro preamplifiers. Machined from a
solid aluminum extrusion, the remote rests
comfortably in the right hand with its minimalist
array of buttons falling within the natural
sweep of the thumb. Simple and logical to
operate, every effort has been made to keep
this product free of unnecessary complexity.
