Chapter 1 – Introduction

Congratulations on your Sphynx purchase. The Sphynx is a professional high quality, modular audio interface

solution for MERGING® Pyramix users, SOFTIMAGE®|DS users and audio professionals.

Features include:

Modular I/O design. The modularity of this unit allows for custom configurations based on quality and audio

interface requirements.

This extended modularity also offers an easy and low-cost upgrade path as user requirements evolve, new standards

emerge and converter technology progresses.

Up to 8 inputs and 8 outputs, in a single unit, using industry standard audio connections.

The signals from the input modules are also fed to the optical lightpipes in ADAT compatible format. This allows a

direct connection to ADAT compatible multitrack devices and other devices such as digital consoles. These optical

lightpipe connectors support up to 8 channels of 24 bit audio on one single optical fiber with no risk at all of line hum

or any other electromagnetic interference.

Rugged internal power supply. This unit accepts both 110 and 220 voltages for worldwide use.

Fully tested for CE compliance for guaranteed safety and stability.

All I/O modules audio connections are made using high quality balanced XLR type connectors.

Clear and easy to use front panel controls.

Extremely high quality 24 bit A/D and D/A using the latest generation in converter technology.

High common mode rejection balanced input circuitry on all analog input modules for optimum rejection of power

line hum, RF interference, voltage drops and other externally generated noise commonly encountered with long audio

cable runs.

All analog balanced output circuitry incorporates the advanced "Twin Servo Drive" output stage for maximum output

signal balance ratio performance, even under adverse asymmetrical loads.

DVD Ready. Support for high Sample Rates such as 96 kHz at 24-bit resolution.

Fits into standard 2 unit 19” rack.

Local control from the front panel (in stand-alone mode).

Remote control from Pyramix Virtual Studio Software.

Selectable monitoring of all 8 inputs and outputs

Very comprehensive choice of Sync sources

Very low jitter and calibrated internal clock

SYNCHRONIZATION

SELECT

The Sphynx can operate in many different synchronization modes. It can synchronize to its internal clock or to a wide

range of industry standard external sources. Pressing the SELECT button allows the selection of the desired

Synchronization mode.

INT:

Sphynx synchronizes and locks to its internal calibrated clock.

ODI:

Sphynx synchronizes to the optical input (ADAT). If no valid sync signal is present at the optical input (when the ODI

mode is selected), the ODI LED will flash. Once a valid sync signal has been detected at the optical input, the ODI

LED will remain lit. If the sample rate of the Sphynx and the ADAT signal are identical, the LOCK LED will light.

The Sphynx is now locked and synchronized to the incoming ADAT signal.

AES:

Sphynx synchronizes to an AES-EBU signal. If no valid sync signal is present at the AES-EBU input (when the AES

mode is selected), the AES LED will flash. Once a valid AES-EBU sync signal has been detected, the AES LED will

remain lit. If the sample rate of the Sphynx and the AES-EBU signal are identical, the LOCK LED will light. The

Sphynx is now locked and synchronized to the incoming AES-EBU signal. If a valid AES-EBU reference signal is

connected to the AES-EBU REF. input it will lock to the “Reference” input. If the Sphynx is equipped with many

AES-EBU input modules, and there is no valid AES-EBU signal connected to the "Reference" input, it will sync to

the first module, based on a priority scheme starting from the first module (input 1-2) to the fourth module (input 7-

8).

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 (KH )

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 X1, X2 or X4 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).

INPUT LEVEL METERS

CH.1 CH.2 CH.3 CH.4 CH.5 CH.6 CH.7 CH.8

These meters provide a very quick and independent state of the current input signals detected on the input modules.

They relay the following information:

LVL - This LED will light if an input signal is detected above –60 dB FS. This is also useful to verify the presence of

any audio at the input.

OVL - This LED will light if an input signal is detected above –0.5 dB FS. This is useful to indicate that the input

audio signal is close to clipping or indeed clipping has occurred. When this occurs, either a reduction of the analog

source level or a decrease in the sensitivity of the analog input of the Sphynx is required (see Chapter 7 for details on

how to calibrate the analog I/O level).

Note: dB FS are referred to Digital Full Scale.

This switch toggles the power source on and off. See Chapter 6 for details on power-up sequence.

Remote indicator

The REMOTE LED type indicator indicates whether the Sphynx unit is in remote or local control. If the REMOTE LED

is lit, the Sphynx is in remote control. In this mode, the Sphynx front panel controls are being controlled via a

software application (such as the Merging Pyramix Workstation).
