11–111 - CascadeThe TM-D4000 can be linked in a cascade with to upto three other similar units, providing up to 128 monochannels of input, together with eight stereo inputs.The stereo outputs of all cascaded console aresummed. The eight output busses and the first fourAux sends may also be summed, turning the chain ofTM-D4000 units into a modular, flexible recordingconsole. Note that Aux sends 5 and 6 are excludedfrom the cascade, and hence can be used locally, withthe built-in effect processor of each cascaded unit—this provides more flexibility in effect processing.In the cascade, one unit is designated as the masterunit. All aux sends and busses that are being summedare passed through to this master unit and are outputfrom the appropriate connectors on the master.In addition, a summed output buss is always echoedlocally at the outputs of all consoles contributing tothe summed buss (this allows more than three MDMunits to be controlled by a cascade of TM-D4000s).Individual busses and aux sends may be excludedfrom the cascade summing, so that they are local tothe unit.In addition to the signal summing described above,the cascade function also links the following func-tions of the cascaded units:• soloing, for both IPS and PFL (5.4, “SOLO”)• snapshot store and recall (8.1, “Snapshot memo-ries”)• option settings (3.3, “Option setup”)• automation setup (automation documentation)• automation mode (automation documentation)11.1Cascade connectionsAs always, connections should be made with thepower to the units turned off.WARNINGOnly use the special TASCAM-suppliedcables (PW-4000CS) to make cascade con-nections. Although computer cables mayappear similar, and may even be wired identi-cally, the cables themselves have differentelectrical characteristics, and damage may becaused to the units if the wrong cables areused.If the use of cables other than these TASCAMcables causes or results in damage, the war-ranty is voided.Slave units are numbered from 1 through 3. Thisnumbering is carried out as carried out below.A cascade of TM-D4000 units is a “daisy-chain”; themaster unit should be at one end of the chain, with itsCASCADE OUT connector [78] connected to theCASCADE IN of slave 1, whose CASCADE OUTconnects to the CASCADE IN of slave 2, etc.No termination is necessary, but all units in a cascadeconnection must be turned on and selected as beingpart of the cascade, even if they are not being used aspart of the chain. It is not possible to have a “dead”unit in a chain or to have a unit in the physical cas-cade chain which does not have the cascade functionselected.1 If your units have not yet been configured foruse in a cascade, turn on and configure theunits that will be slaves first, and then turnon and configure the unit that will act as thecascade master.2 On the first slave unit (connected to the mas-ter unit) use the DIGITAL I/OCASCADE screen to select the SLAVE1 ID for this unit.3 Move the cursor to the CASCADE ON/OFF button at the top of the screen, andturn the cascade on for this unit:4 Repeat this procedure for all the other slavesin the chain, assigning the appropriate ID toeach slave.5 Finally, set the master unit’s ID to MASTER,and turn the cascade ON.
