Thank you
We extend our hand in deep gratitude, thanking you for selecting the Takumi K-10 pre-amplifier.
This pre-amplifier is easy to install and use but there are some precautions that need to be observed
in order to attain maximum performance, safety and reliability. Please therefore read carefully thru
this owner’ s manual before installing your K-10.
If there any doubts in your mind or should you require any supplementary information, please do not
hesitate to contact your distributor or Robert Koda directly.
Cordially,
Robert Koch.
Important safety information
This unit is designed to be earthed.
Please therefore ensure that the AC power cable you select to use with the K-10 is a three wire type
that is earthed. Failure to do so may render a potentially dangerous situation.
There are no user serviceable parts inside. Please therefore do not attempt to open, adjust or modify
this pre-amplifier.
Power up and power down sequence.
Due to the fact that the K-10 does not incorporate power up / down muting circuits, a large pulse
may be emitted from the speakers if the pre-amplifier is not powered up or down in the correct
sequence. This pulse may be objectionable or even damaging to your loudspeakers and in particular
active bass systems so please:
On power up, turn the pre-amplifier on twenty seconds or more before the power amplifier(s).
On power down, turn off the power amplifiers before turning off the pre-amplifier.

Placement requirements
Owing to the substantial 27Kg weight of the K-10, this pre-amplifier should be placed on a firm,
stable and solid surface. The use of a dedicated audio stand or plinth may provide some degree of
increased performance.
Areas of high humidity, direct sunlight, exposure to flammable gas or possible exposure to liquids are
not suitable for placing the K-10 in.
This pre-amplifier is not designed to stand directly on top of other audio components or have other
audio components placed on top of it.
Feet
Four basic feet are installed onto the under-chassis of the pre-amplifier. Their purpose is to mainly
provide “finger space” while lifting the unit. Five Sorbo Gell feet are provided for use on final
installation. Typically one would place three of the feet on the left under-side area and two on the
right. This is to compensate for the extra weight of the left hand portion of the pre-amplifier. It may
be desirable to place a thin piece of grease proof paper or similar underneath each Sorbo Gell foot if
the added sticky-ness of the foot is not desired. In addition the grease proof paper may prevent
possible staining that the foot may leave behind on the component stand.
