WCLK - S, WCLK - L
(page name)
WORD CLOCK – SINGLE, – LINKED, The »S« and »L« letters indicate the Sing-
le and Linked modes. Refer to the »ADJ-WCLK« parameter on the GLOBAL
3/4 page explained in the OPERATION chapter, »Setting System Functions«
for more information. The factory default is Single mode (– S).
OUT 1 - 4
(page name)
OUT 1 – 4 is the Word Clock out pair that can be configured on the current page.
FREQ
(function)
FREQUENCY sets the clock rate of the selected output pair. The factory
default is 44.1 kHz.
24Hz...60Hz, 8.0kHz...24.576MHz
(setting)
Altogether 36 different audio-related clock rates between 8.0 kHz and
24.576 MHz can be selected individually for each Word Clock output pair.
Also 8 pilot tone clock rates from 24 Hz to 60 Hz are available for synchroni-
zing pilot tone resolvers, timecode generators or film projectors and 5 dif-
ferent high-accurate clock references known from GPS receivers or atomic
clock generators. The individual rates are shortly described under
<FORMAT>. Refer to the »Synchronizable and Generatable Clock Rates«
section in the appendix for a full list of all clock rates.
‹FORMAT›
(message)
FORMAT provides information on the output format of the currently selec-
ted Word Clock out pair. This parameter is provided for information purpo-
ses only (this is why it is displayed in brackets.) Setting is made against the
setting of the FREQ parameter. The factory default is WORDCLK.
WORDCLK
(setting)
WORD CLOCK This setting means that the rate is output as set.
SUPERCLK
(setting)
The SUPER CLOCK function is available for Word Clock rates of 44.1 or
48 kHz only. It is used for a rate adaptation required for Digidesign Pro-
Tools™ systems (not! ProTools HD™). Accordingly, the 44.1 kHz and 48 kHz
rates are available twice for selection: for both the WORDCLK and the
SUPERCLK, for ProTools™ systems, settings.

Word Clock rates are set independently
of externally applied clocks. Thus, iCLOCK
provides Word Clock conversion from all
supported input rates to all generatable
output rates!
GPS / Atomic Clock + Audio Player
References
As so-called GPS or atomic clock references,
the iCLOCK and iCLOCKdp are able to lock
and generate the following frequencies:
1.0Mhz, 2.5MHz, 5.0MHz, 10.0MHz
Furthermore, the iCLOCK and iCLOCKdp are
able to generate the following basic clock
rate used in e.g. CD players:
16.9344MHz
This clock signal can be used to replace a
CD player‘s internal system clock with the
16.9344MHz clock signal generated by the
iCLOCK or iCLOCKdp. Thus, a CD player
can benefit from the iCLOCK‘s lowest-jitter
clock generation which leads to an audible
sound improvement of the CD player‘s DA
converters!
Before replacing your CD player‘s internal
basic clock, check carefully if the frequency
of 16.9344MHz is the right one for your CD
player!
Due to the internal signal phase corrections
the synthesizer can re-lock temporarily when
switching Word Clock clock frequencies.
This does not affect the output signals or
functionality of iCLOCK.

WCLK page
Configuring the Word Clock Outputs
The WCLK OUT 1–4 display pages allow for configuring the eight wordclock
outputs provided by the iCLOCK standard version . Four output pairs
comprising one top-row and one bottom-row output each are available on
the rear panel. These are numbered as WORD CLOCK OUT 1–4. The BNC
terminals making up a pair are marked as »A« and »B«, thus allowing for a
simple documentation of the connected devices.
