1. Introduction
Welcome
Congratulations, and thank you for purchasing the Merging Technologies Sphynx 2 audio converter. The
Sphynx 2 is an extremely powerful 8-channel audio converter for independent simultaneous analog-
to-digital (A/D), and optional digital-to-analog (D/A) conversion. The Sphynx 2 has a modular structure
enabling the use of up to 7 I/O modules.
For a more detailed description of the Sphynx 2, please look at the Merging website www.merging.com.
General introduction
The Sphynx 2 is jointly developed by Merging Technologies and Digital Audio Denmark (DAD) and is one
of the most advanced and sonically pure converter ever developed.
The sample rate capabilities of this unit allow for 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192 kHz,
DSD 1-bit 64FS, DSD 1-bit 128fs and even supports the new Philips DXD (Digital eXtreme Denition) 24
bit, 352.8kHz format for SACD production.
Sphynx 2 must be controlled from within the Pyramix screen via a simple RS422 link using DAD’s
DADman PC remote control software.
The modular design of the Sphynx 2 offers 8 channels of A to D conversion with the option of inserting up
to two 4 channel D to A cards resulting in the most cost-effective means of achieving 8 channels of AD-
DA in 1-bit DSD.
A range of audio interfaces for external equipment are available including MADI, SDIF3, AES-EBU, TDIF
and ADAT. Pyramix DSD users will probably require the MADI interface offering 8 channels of DSD/DXD
in a single MADI link and allowing two units to be synchronised using a second MADI link for the Pyramix
16 channel DSD system.
Before you start
· Place your Sphynx 2 on a hard and dry surface or mount it into a 19” rack, and leave plenty of room
for ventilation.
· In order to meet the EMC requirements of directives 89/336/EEC and 93/68/EEC, and in order to
obtain the high performance the Sphynx 2 is capable of, you must use good quality correctly shielded
cables for all external connections when installing the Sphynx 2. For the power connection, a
normal unshielded power cable with a proper ground can be used.
· Make sure that your sound system is at a safe volume level.
The following sections describe how to get started with installing and operating your Sphynx 2.
2. Control software installation
2.1 PC recommendation
The DADman software operates on any Pentium computer with Windows XP installed and needs one

3. Hardware Installation
This section will take you through installation of your Sphynx 2. We will describe how to connect the
analog and digital audio cable, and how to mount additional I/O modules.
3.1 Rear Panel
Installing I/O cards
If you need to install or change an I/O module the following procedure must be used.
Place the Sphynx 2 on a dry, steady, horizontal surface. Turn off the power and remove all cables. On
the rear panel of the Sphynx 2 there are 7 slots for I/O card mounting. The remote control module must
always be installed in the converter. Free slots are tted with Blanking Plates.
A drawing of the Rear Panel can be seen below:
There are 2 different sizes of I/O module: 1-slot modules and 2-slot modules. Decide where to place the
module. (When mounting a 2-slot I/O module make ensure there are 2 free slots, one above the other, on
the back panel of the Sphynx 2.)
To remove blanking plates for I/O module slots, remove the 2 screws at each side of the plate. Use a
posidrive screwdriver (no. 1). Only remove the number of blanking plates necessary to t the I/O module.
All slots must be covered with a blanking plate or have an I/O module tted before the unit is powered up.
It is very important to carefully insert the I/O card horizontally into the Sphynx 2. There are 3 guides
inside the Sphynx 2 to help guide the I/O card correctly into place. Do not use force to insert the I/O card.
This may damage the card.
When the cover plate of the I/O card covers the hole created by removing the blanking plate, the
2 (1 slot) or 4 (2 slots) screws from the blanking plate are used to secure the I/O card. Tighten the screws
carefully and be careful not to damage the threads.
The I/O card is now properly installed.

ANALOG OUTPUTS
Connecting the analog audio cables
Turn down the sound system volume, before rigging the Sphynx 2’s analog audio cables. On the right
side of the rear panel, you will nd 8 balanced XLR input connectors marked 1 to 8. These analog inputs
correspond to the 8 channels, and can be used to connect a balanced line input signal (+12 to +30 dBu).
The input level can be adjusted using the small adjustment screw next to the XLR input connectors.
If any of your I/O cards are DA modules, you should also connect the balanced XLR connectors at this
point.
Connecting the digital audio cables
If one or more I/O card is a digital audio interface, you should also connect the relevant cables to the
appropriate connectors.
Connecting the digital sync input/output
On the left side of the rear panel, you will nd the Word Clock external synchronisation input and output
connectors marked WC in and WC out, the AES 11 input connector marked AES11 in and the Video
Black and Burst input connector marked Video in.
If you wish to synchronise your Sphynx 2 to a WordClock signal, connect this signal to WC in through the
BNC socket. The Word Clock signal can be 44.1, 48, 88,2 or 96 kHz +/- 10%.
If you want to use AES11 as external source for synchronising for the Sphynx 2 connect an AES11 signal
to the XLR connection market AES11 in.
To synchronise the Sphynx 2 to a Video Black and Burst signal connect the signal to the Video in socket
with a BNC cable.
To use the Sphynx 2 as master studio clock for other units, connect these units using a BNC cable to WC
out. The Sphynx 2 will generate a synchronising signal with the same frequency used for the A/D or D/D
conversion with a precision better than 10 ppm.
The Word Clock output can alternatively serve as SuperClock output. In the DADman program you
choose between WordClock and SuperClock output for the BNC WC out connector.
There will always be a signal on WC out. Either a WordClock or a SuperClock signal. This means that
the Sphynx 2 can convert a Video Black Burst or an AES11 signal to a WordClock or a SuperClock sig-
nal.
Connecting the Power Cable
The Sphynx 2 runs on 90-260 V, 50-60 Hz AC voltage. Excessive voltages can seriously damage the
Sphynx 2, so make sure that your AC power matches the voltage of your Sphynx 2.
When you connect the power, use the cable you received with your Sphynx 2 and plug it into a grounded
outlet. For safety and EMC reasons, and to prevent audio hum, the system must be properly grounded.
Connecting the RS422 cable for remote control
The Sphynx 2 must be controlled from a PC via RS422.
Merging can provide one of three alternative solutions:
1. Easy Sync USB to one RS422 break out (one RS422 output).
2. Easy Sync USB to four RS422 break out (four RS422 outputs).
3. Antona RS232 to RS422 converter (RS232 from the computer com port)
