Setting up audio and syncing
Clarity X software version 1.3.00 – Build 3275 – Reference manual (updated 2016-10-18) 63
Sync Source parameter
Settings: AES 1/2, AES 3/4, AES 5/6,
AES 7/8, AES 9/10, AES 11/12, AES
13/14, AES 15/16, TOS 1/2, MADI
Use the Sync Source parameter to select the ex-
ternal signal source that ClarityX should sync to.
When the Clock Master parameter is set to “In-
ternal”, the Sync Source setting is irrelevant.
However, you should be aware that you can use
this parameter to preselect a sync source that
will be used when you switch ClarityX AES di-
rectly from Internal to External Sync.
External Clock Accept rate parameter
Settings: 48 Only, 44.1 Only, Automatic
When you have set the Clock Master param-
eter to External, you can use the External Clock
Accept rate parameter to select the sampling
rate(s) ClarityX will accept from the external sync
source.
When selecting one of the “Only” rates, ClarityX
will spend less time on judging if the incoming
rate is valid. Accordingly, lock-up time may be
shorter.
These “Only” settings can also minimize the gen-
eral disturbances (during lock-up) on the digital
outputs of Clarity X. This is beneficial if speak-
ers are being fed from ClarityX’s digital outputs.
These settings may also be beneficial when used
in a critical live setup to ensure that downstream
disturbances are minimized.
48 Only setting
Clarity X will only lock to incoming signals run-
ning at 48 kHz. This may be a good choice when
used in a broadcast setup where everything is
running synchronously at 48 kHz.
44.1 Only setting
Clarity X will only lock to incoming signals run-
ning at 44.1 kHz.
96 Only setting
Clarity X will only lock to incoming signals run-
ning at 96 kHz.
Automatic setting
ClarityX will automatically lock to incoming sig-
nals running at either 44.1 or 48 kHz. This setting
is convenient if you work with projects with dif-
ferent sample rates in a typical post-production
studio setup. Combined with the Clock Free-
wheeling parameter set to Audio Muted, this
configuration is very flexible, while the risk of au-
dio glitches in the studio reaching the speakers
during sample rate changes is minimal.
In Automatic mode, obtaining lock to a digital
reference signal may take ClarityX a little longer.
Clock Freewheeling parameter
Settings: Audio Unmuted, Audio Muted
Use the Clock Freewheeling parameter to speci-
fy how ClarityX should behave when the no ex-
ternal sync source is present.
Clarity X is the last element in the signal chain
before your speakers. This is why we put a lot of
effort into ensuring consistency and reliability on
the digital outputs, which can be trickier to han-
dle than analog outputs. The Clock Freewheeling
technology is part of these efforts.
When sync is lost, ClarityX will continue running
on the “last good rate”. If possible, ClarityX will
run on a 96 bit-precision version of the last good
sample rate that the device received. This will
only generate few potential sample slips down-
stream and on the inputs (which may still receive
audio), so the audio quality is not significantly
reduced.
However, in some borderline cases it may not
be possible to calculate the last good incoming
sample rate. In such a situation, ClarityX will re-
vert to the internal 48 kHz clock, and audio will
still be sent through. Expect more sample slips
in such a situation.
Audio Unmuted setting
When sync is lost and the Clock Freewheeling
parameter is set to Audio Unmuted, ClarityX will
continue running on the “last good rate” as de-
scribed in the previous paragraph.
Use this setting if you work in a live situation and
would rather accept a compromised audio signal
when sync is lost (with sample slips in the audio
stream) than having no signal at all.
Audio Muted Setting
When the sync source is not present and the
Clock Freewheeling parameter is set to Audio
Muted, all AES outputs are turned off – meaning
no audio data and no AES carrier (no clock) are
being sent out.
