VIDEO
:
Sphynx synchronizes to a video signal and automatically detects and adapts to either a PAL or NTSC signal. If no
valid sync signal is present at the video input (when the
VIDEO
sync mode is selected), the
VIDEO
LED will flash.
Once a valid video signal has been detected at the video input, the
VIDEO
LED will remain lit. If the video signal is
either a NTSC or PAL compliant signal, the
LOCK
LED will light. The Sphynx is now locked and synchronized to
the incoming video signal.
WCLK
:
Sphynx synchronizes to a Wordclock signal (TTL or CMOS level square wave at the sampling rate selected on the
front panel). If no valid sync signal is present at the Wordclock input (when the
WCLK
mode is selected), the
WCLK
LED will flash. Once a valid sync signal has been detected at the Wordclock input, the
WCLK
LED will remain lit. If
the sample rate of the Sphynx and the Wordclock signal are identical, the
LOCK
LED will light. The Sphynx is now
locked and synchronized to the incoming Wordclock signal.
S/PDIF
:
Sphynx synchronizes to a S/PDIF signal. If no valid sync signal is present at the S/PDIF input (when the
S
/
PDIF
mode
is selected), the
S
/
PDIF
LED will flash. Once a valid sync signal has been detected at the S/PDIF input, the
S
/
PDIF
LED will remain lit. If the sample rate of the Sphynx and the S/PDIF signal are identical, the
LOCK
LED will light.
The Sphynx is now locked and synchronized to the incoming S/PDIF signal.

SAMPLE RATE (KHz)
SELECT
Sphynx supports a wide range of sample rates. The desired rate is selected by pressing the
SELECT
button.
There are three possible modes available when selecting sample rates.
Mode x1: In this mode, the available sample rates are: 32 kHz, 44.1 kHz, 48 kHz and AutoDetect.
Mode x2: In this mode, the available sample rates are: 64 kHz, 88.2 kHz, 96 kHz and AutoDetect.
Mode x4: In this mode, the available sample rates are: 128 kHz, 176.4 kHz, 192 kHz and AutoDetect.
Switching between modes is allowed by pressing the
SELECT
button for more than ~2s.
AutoDetect SR mode
In this mode, the sample rate is automatically determined and selected based on the signal present at the selected
synchronization source.
When in AutoDetect SR mode, the
X
1,
X
2 or
X
4 LED flashes.
For selected sync sources such as INT, ODI or VIDEO, the analysis of the incoming (and desired) sampling rate is
based on the signal present at the ODI input (usually the return from the Workstation or system to which Sphynx
would be connected to both ways). This allows for completely automatic sample rate detection and switching for
Sphynx when using Merging’s Pyramix Workstation, SOFTIMAGE®|DS, or other external ADAT compatible
devices such as Multitrack Digital Recorders or Digital Mixing Consoles.
For selected sync sources such as AES, WCLK or S/PDIF, the analysis of the incoming (and desired) sampling rate is
based on the actual sampling rate present at the selected sync source (AES-EBU, WCLK or S/PDIF).
