7 - Recording/playback with cascade connections Overview of the cascade function Using the cascade connection capability of the DA-3000, multiple DA-3000 units can be controlled simultaneously. A multichannel system can be realized by synchronizing recording and playback. Record button pressed Master unit Slave unit Synchronized recording starts Timing adjustment period Recording and playback with cascade connections involves the following two types of synchronization (timing and clock). Timing synchronization Depending on the cascade setting, slave units will synchronize to the master unit when recording/playback starts. Clock synchronization During recording and playback, the internal clock of the master unit or an external clock generator is used to synchronize. CAUTION The following functions cannot be used during synchronized recording/playback using cascade connections. • The included RC-10 remote control cannot control slave units. • PCM recording using the DIGITAL IN (AES/EBU) jacks is not possible. • PCM recording using the DIGITAL IN (S/PDIF / CASCADE) jacks is not possible. • Sync recording functions are unavailable. • LEVEL, DD and TIME mode auto track functions are disabled. • Auto mark functions are unavailable. Connections and preparations Preparing media When conducting synchronized recording and playback, use identical media (same brand, capacity and model number) in the master and slave units. Use of different media could cause media access speed differences, resulting in synchronization discrepancies and other unpredictable problems. We have posted a list of media that we have confirmed for use with cascade operation on the TEAC Global Site (http://teacglobal.com/). Selecting the media Set the media for the devices (master and slave) to be cascaded. Select the same type of media for all devices (CF or SD). See "Selecting the media used" on page 21 for details. Preparing cables Use high-quality digital coaxial cables (75Ω impedance) for cascade connections. (Do not use analog RCA cables. Doing so could cause malfunction.) When using word clock, connect with high-quality BNC cables(75Ω impedance). Setting the recording file format When recording, set the master and slave units to use the same recording file format. (Recording and playback is possible with the units that are using different file formats and sampling frequencies, but synchronization will not occur with sampling frequency precision.) (See "Setting the recording file format" on page 23.) CAUTION During cascade operation, do not record files with different file formats or sampling frequencies inside the same folder or copy such files from a computer. Doing so could cause malfunction. 42 TASCAM DA-3000
