We will call it here "the Interface". The chart below and on the next page explains the basic setup and functions of the interface. On the next pages you will find diagrams of the signal flow and basic steps for a quick start. WORKSTATION24 AD/DA MONITOR &...

2. Setting up your system. This diagram shows how to set-up your system. This is the basic setup for a digital workstation and two DAT machines. If you don't use a computer please refer to chapter 6. If you want to use external sync please refer to chapter 7.

There are two ways of precise alignment of in/out level. One requires a reference level tape or CD, while the other requires hi-res digital meter such as Mytek DDD-603. The reference tape containing various tests signals is available from Mytek .

4. Jitter reduction and fromat conversion. Digital inputs and outputs. Jitter reduction . The interface employs three jitter reduction circuits. One is for the digital inputs, one for external wordclock input and one for the digital outputs and D/A converter. They stabilize the digital audio clock without altering the audio data.
5. 44.1k or 48k ? The difference is mainly in the audio band. In case of the Workstation AD/DA the passband for 44.1k is 22k and it is 24k for 48k sampling rate. Although you can hear the benefits of the bandwith extended to 40k, this difference is miniscule.
6. Using Workstation AD/DA as a stand alone converter. Workstation 24 It can be used as a front end for any DAT machine. It certainly sonically outperforms all of them. -103dB THD of the A/D converter is about 15dB less than that of any DAT machine. The converter sounds smoother, more natural and transparent.

7. External synchronization. External synchronization is needed whenever the interface’s A/D clock has to be referenced to a clock of a different device in the system. Here are some examples of the most popular applications: Sound for picture. The wordclock input of the interface must be connected to a wordclock generator synchronized to video.

Multichannel operation. You can daisy-chain several interfaces in order to get more channels. Let's say you want 8 channels of input/output for your Sonic Solutions station. You will need 4 Workstation AD/DA interfaces and 3 BNC type 75 Ohm cables. You will also need 2 "T" BNC type adapters (Radio Shack). First interface is the master and the rest are slaves.

Digital console. If you are using the interface with a digital console such as Yamaha 02R you may either slave the interface to the console or opposite. The latter will not compromise A/D conversion since the converter will be referenced to its internal crystal with almost no clock jitter. WORDCLOCK IN WORDCLOCK OUT DIGITAL...

6. HiBit-16 (tm) -putting 24 bits onto 16 bit digital tape. Although the DAT and CD are "16 bit" it is commonly known that 16 bit converters are really 15 bit or less and you need a higher resolution converter to approach theoretical limitations of a 16 bit medium. But still higher resolution is needed for more sound information, especially for fine details, reverbs and ambience sounds.
(w/ optional hardware). Both digital input and digital throughput are provided on two XLR connectors mounted in the back. The meter accepts AES/EBU or SPDIF inputs. An RCA to XLR adaptor is required for SPDIF signals. c 1994 Mytek Technologies...
