Positioning The P10 Chassis Components - CH P10 User Manual

Gently pull the umbilicals into position to be connected to the audio chassis, noting which is which thanks to
the color-coded identification rings.
Move the audio unit as close as possible to the rack/support so that you can thread the umbilicals through
the rack (if necessary) before moving it back into position. Connect the left umbilical to the left input
socket and the right umbilical to the right input socket. The plugs on the umbilicals will only connect in one
position. Turn the connector in the socket until you feel it engage and then gently push it home until you
hear a locking sound.
DO NOT force the umbilical connectors into the sockets. This will risk damaging the connecting pins and
disable your P10.
If you feel resistance when you insert the connector, check that you are trying to connect the proper pairs
of umbilicals and connectors together. Please note that the two connectors have the same diameter but a
different number of pins, so it is not possible to plug an umbilical into the wrong socket.

3.4 Positioning the P10 chassis components

Each P10 chassis is supplied with a set of four support discs. These have a groove machined in the upper face
that fits over the rubber ring in the underside of each foot. Lift each corner of the chassis in turn and position
the disc beneath each foot. The groove that interfaces with the rubber ring will ensure that the footer disc
stays in place if you slide the unit.
As well as making the units easier to position, the support discs can also offer a superior interface between
the grounding spikes and the supporting surface. The spikes are designed to drain internally generated
energy away from sensitive circuitry and into a dispersive support structure, but if the supporting surface
is extremely hard or forms an impedance mismatch with the spike tips, the material and footprint of the
support discs can function as a lossy mechanical buffer, easing the passage of mechanical energy out of the
unit. As a rule, the support discs work well with very hard surfaces, but results will vary with system and
supporting surface. Once set up and warmed up, compare the sound of the unit(s) with and without the discs
in place.
Use the red screwdriver to wind down each of the four spikes until they touch the surface (or disc)
underneath. You will feel a slight resistance due to the chassis' weight. Then turn each spike by the same
amount, for instance one more full turn. This should ensure that the load is evenly applied on all four spikes.
It is worth using a spirit level to ensure that the P10 units are perfectly level. If they are not, adjust the spikes
with the screwdriver. Once this is done, simply check that all four spikes show the same resistance to turning.
This means that the spikes are rigidly coupled to the supporting surface and equally loaded.
Replace the top caps. Their magnetic coupling will hold them in place.
