Clocks - MSB Technology Select DAC II User Manual

Clocks

One of the most important parts of a DAC is the clock. Clock
jitter is responsible for the digital harshness most often found
in digital products. The MSB clocks are the lowest jitter in
the world. To maintain that low jitter they must be physically
located extremely close to the DAC modules themselves.
This is why outboard clocks cannot compete with a low-jitter
internal clock.
The SELECT ships with a Femtosecond Galaxy Clock
standard, providing 77 femtosecond jitter performance. There
is also an upgrade available to our Femto 33 Clock, the lowest
jitter clock on earth.
The Femtosecond Clocks plugs into the clock upgrade header
on any DAC IV, DAC V or SELECT DAC with an immediate
sonic benefit. An excellent DAC clock tends to reveal the true
The Femto 33 Clock offers the lowest jitter in the world and is a great
upgrade, with half the jitter of the Galaxy.
Digital Input Module - Renderer
This digital module contains an impressive audio
renderer. This input is connected to a computer
network and allows the DAC to become an endpoint
for a range of music players and servers. A separate
manual is included for this input. When installed
the IP address of the Renderer can be found in the
ABOUT section of the display menu.
The Femtosecond Galaxy Clock offers the second lowest jitter in the
world and is standard in the Select II.
nature of the original music. The Select with a Femtosecond
Clock reveals fine, delicate, very dense harmonics that are
accurately organized and therefore correctly reveal the true
sound of the instruments and voices. The lower the jitter of the
clock the more noticeable the effect which scales directly with
jitter. The harmonic congestion that translates to harshness
and the familiar digital "annoyance factor" is just absent. The
music and instruments sound like they are coming from live
mic feeds on the best recordings.
It is easy to replace the clock. Turn the DAC over on a padded
surface and remove the 4 large corner screws. Lift the lid. The
clock can be removed and replaced with the tools provided
with a clock upgrade. Alternatively you may send the DAC
back to the factory to have the clock installed.
