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.

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 

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.

The Femto 33 Clock offers the lowest jitter in the world and is a great 

upgrade, with half the jitter of the Galaxy.

The Femtosecond Galaxy Clock offers the second lowest jitter in the 

world and is standard in the Select II.
