The most important thing to note about Ribbon microphones is that nearly all Ribbon Microphones do not require phantom power PLEASE NOTE unless a Ribbon microphone calls specifically for phantom power sending phantom power to a ribbon micraphone will severely damage it usually beyond repair Regardless of the microphone type you are using we recommend reading your microphone s user s manual thoroughly before engaging phantom power or if any other usage questions may arise 10 PreSonus 2007 OPERA TION 3 2 DIGITAL CONNECTIONS AND SYNCRONIZATION 3 2 1 ADAT Optical Lightpipe ADAT is an industry standard abbreviation for the ADAT Lightpipe protocol which transfers eight tracks in a single fiber optic cable Supported sample rates are 44 1 kHz and 48 kHz When you are utilizing the eight DigiMax D8 preamplifiers and converting to the digital optical output connect one ADAT optical cable from the ADAT output on the back of the DigiMax D8 to the ADAT optical input on your digital audio interface workstation or digital mixer To synchronize your system to the DigiMax D8 s internal clock set your other device to receive external word clock via its ADAT optical input You may need to consult your device s user manual for instructions on how to do so 3 2 2 BNC Sync and Word Clock When using multiple devices connected through digital audio formats like S PDIF AES EBU ADAT or TDIF it is necessary to synchronize them to a singl
3. Devices Whether you are using the ADAT output of the DigiMax D8 to generate word clock or you are using the BNC word clock output of another device as your word clock generator it is necessary to denote one device as the master word clock device to which all other digital devices are synced or slaved The DigiMax D8 should perform equally well as a master or a slave in most cases although syncing it to a lesser quality clock source may affect performance Not all word clock generators are created equal The general approach is to determine which device has the best clock from which to reference and to designate that device as the word clock master This is done with careful listening and A B testing Once you ve determined which device is to be your Master clock you will need to sync the remaining digital devices either through series or parallel distribution or some combination thereof Of course if your digital device chain only consists of one master and one slave syncing the two is as simple as connecting a 75 Q BNC word clock cable from the output of your master device to the input of the device you are slaving When working with multiple slaved devices the job gets a bit more complicated Series distribution requires that your digital devices have both a BNC word clock input and a BNC word clock output Parallel distribution uses a BNC T connector attached to the BNC word clock input of each slaved device This allows the word clock signa

14. e word clock generator Word clock is used to keep a perfectly timed and constant bit rate between all synced devices to avoid data errors A word clock generator creates digital pulses that contain no other data i e audio These pulses clock the internal oscillators of each device and are essential to avoid frequency drift A word clock signal is bundled with the audio data in the ADAT Lightpipe protocol however many engineers prefer to keep word clock sync and audio separate from each other This is where BNC word clock connections come into play and the DigiMax D8 has a BNC word clock input for just this purpose You will find BNC cables used to deliver dedicated word clock in many quality studios and broadcast facilities worldwide BNC cables are rugged lock into position and can carry clock signals much farther than the standard optical cable A BNC word clock cable is a 75Q shielded coaxial cable with standard twist lock BNC type connections on each end P ease note BNC cables are made in several impedances The DigiMax D8 requires an impedance of 75 Qs to achieve consistent sync To synchronize the DigiMax D8 via BNC word clock you will need to run a BNC word clock cable from the BNC word clock output of your external device to the BNC word clock input of your DigiMax D8 From the front panel of your DigiMax D8 select external sync using the clock button 11 PreSonus 2007 OPERA TION 3 2 3 Master Slave and Multiple Digital
