3. INTRODUCTION
In purchasing the Q-ADAT, you have acquired an ADAT® format multi-channel digital to
analog converter of high class that meets many of the demands of the home/pro studio.
The mar- ket size for digital audio interfaces and computer based digital recording/editing
has increased in a massive way. With systems available at very low prices, more and
more users are utilizing this technology . Many current digital systems also feature ADAT®
compatible connectivity to facilitate the simple connection between digital devices from
different manufacturers.
About the ADAT® format...The ADAT® protocol is a digital audio transfer protocol format
developed by ALESIS Corporation. It allows 8 channels of digital audio data to be transferred through a single optical cable (light pipe). Since the development of ADAT® many
professional companies have adopted this format as the defacto standard for the reliable
transfer of high quality multi-channel digital audio between devices. You can now find
ADAT® I/O (input and output) connections provided on a wide range of digital audio
equipment from digital mixers, recorders, multi-channel microphone pre-amps and the
like.
The Q-ADAT is an extremely portable multi-channel analog to digital audio converter. It
reliably converts 8 channels of analog audio to pristine 24-bit digital audio while providing
the out- put via the popular ADAT® format. This single rack unit can now solve many of
the connectivity issues which are raised in a large range of situations. The A08 is the perfect addition to your ADAT® compatible mixer, recorder, computer based audio interface,
etc.
Add more connectivity and analog inputs to your ADAT® compatible devices!
4. Q-ADAT FRONT panel
Analog inputs
Eight (8) unbalanced inputs are provided on the front panel of the Q-ADAT. Use standard 1/4” audio cables to connect your analog source signal to the Q-ADA T. The Q-ADAT
is designed to function accepting -10dB line level signals.
LED indicator
Switch and indicator led are located on the right hand side of the front panel. The unit will
be powered on when the switch is configured in the down position. The led will illuminate
to indicate that the power is switched on.
5. Q-ADAT Back panel
ADAT optical output
On the rear of the Q-ADA T there is 1 x ADAT® optical light-pipe output connector. It is covered with a small black plastic protector plug. Please remove the plastic connector plug
before connecting your optical cable. Simply connect a standard optical cable from this
output to your des- tination devices ADAT® input.
Word clock input and output
Two BNC connectors are provided on the rear panel for input and output of word clock
signal. Word clock sync allows multiple digital devices to keep the audio in sync. Each device's internal clock operates at a sample frequency slightly different from its neighbor,
even if all devices are set to the same nominal rate. As a result, audible pops and clicks
may result when un-synchro- nized digital sources are mixed. We recommend using 75
Ohm coaxial cable for your connections.
Sync selector switch
The sync selector switch determines which word clock generator the Q-ADA T receives its
sync from. If it is set to INT(internal/master), the Q-ADAT generates its own clock internally . It will also pass it’s generated clock out the W/C output connector for connection to
other devices. When set in the EXT(external/slave) position the Q-ADA T is set to operate
using another devices generated word clock signal. The word clock signal is also passed
through the W/C output for daisy chaining other devices. Daisy chaining word clock signal will also have it’s own sync problems when using many devices or long cables. Termination at the end of your word clock chain is also necessary using a 75 Ohm resister.
It is recommended if you have many devices that you use a dedicated master clock generator that individually supplies word clock to each device.
Sample rate selector switch
The Q-ADAT can operate at either 44.1kHz or 48kHz sample rate. This is the sample
rates allowed by the ADAT® format. Please select the desired sample rate for your current project. Your selection should match the sample rates of all other digital equipment.
6. APPLICATION
Using the SM Pro Audio Q-ADAT
It could not be simpler to use and operate the Q-ADAT. Please check through the following oper- ational checklist for a brief introduction to using the Q-ADAT.
Operational checklist:
1. Firstly consider your audio project basics:
A) Clock/sync considerations! Do you need to clock/sync the Q-ADAT device to other
digital devices? If so which device should be the master clock generator? How should
I connect the word clock cable? If you have more that one digital device functioning together that offer word clock sync connectors it is advisable to sync them via coaxial
cable. There can be only one master clock generator device in a multi device configuration. All other devices becomes slave receivers. Your word clock coaxial cable
should be connected from the word clock output of your chosen master clock generator device to the word clock input of the Q-ADAT. If you need to to daisy chain additional connections simply connect the word clock output of the Q-ADAT to any further
devices word clock inputs. The last device on your chain should be terminated with a
75 Ohm BNC terminator plug connector.
Ensure that your chosen master clock generator device is configured as the to use
INTSync (Master). All other devices should be selected to EXTsync (Slave). Your QADA T has INT& EXTsync available via switches on the rear panel in addition to providing word clock input and output BNC connectors. Make your cable connections and
INT/EXTsync selection based on your projects design.
B) What sample rate is your audio project going to be using? The Q-ADA T sample rate
selector switch on the rear panel allows for either 44.1kHz or 48kHz operation. Check
the sample rate setting of your project and other digital devices you plan connecting
together. Ensure the Q-ADAT is using the same chosen rate!
2. Make your physical analog and digital connections. Connect your analog signals
you wish to convert to ADAT® multi-channel (8ch) digital format to the inputs on the
front of the Q-ADA T. Connect your ADA T optical cable from the Q-ADAT’s ADA T® output connector to your destination devices ADATinput connector. Your Q-ADAT should
now be fully configured for use. All incoming analog signals can now be converted to
24-bit digital audio at your selected sample rate and output via the ADAT® optical connector on the rear panel. The Q-ADAT is the perfect addition to your ADAT® compatible mixer, recorder, computer based audio interface, etc.
Add more connectivity and analog inputs to your ADAT® compatible devices!
