6 - Surround modes—Monitoring issues6–2This facility allows the selection of a fader patternthat suits an individual way of working.6.2 Monitoring issuesThe main issue that affects surround mixing is that ofmonitoring.Because the TM-D4000 uses the buss outputs as thesources for the surround mix, and these busses areoutput in parallel to all the interface cards fitted in theexpansion slots, it is possible to use an IF-DA4000analog interface card in one slot, and an appropriatedigital format (TDIF-1, AES3-1992 or ADAT) cardin another slot. The multitrack output to the digitalmastering recorder is therefore also output to the ana-log buss outputs, which are connected to the monitor-ing amplifiers.However, this approach uses two of the three inter-face slots available, and on a non-cascaded setup, thiswill probably not provide enough inputs for the mix-ing of digital material.One solution is to use the TASCAM IF-DA8 (pro-vided the mix is to be made to a TDIF-1-compatibleunit). The “pass-through” of the digital audio,together with the conversion of these signals, makethis an attractive option.It is also possible to use the on-board D/A convertorsof the multitrack unit, with suitable source/tape mon-itor switching, to drive the monitoring system. Thisoption requires no additional convertors, and mayprove to be the most convenient option under somecircumstances.6.3 Buss delayThe DELAY screen (accessed through the SHIFTedOPTION key [5]) can be used in surround mode to setthe delay of the busses relative to each other.Use the POD controls to set the delay, which can beused to compensate for delay caused by speakerplacement, etc. The right switch of the top two PODrows can be used to turn the delay on and off. the leftswitch of these PODs is used to change the digit thatis adjusted using the POD knobs.POD 1 in the last row is used to change and set thedelay value for all busses simultaneously. Change thevalue with the pod knob and press the right switch toset the value.POD 4 of the last row changes the delay time unitsbetween samples and milliseconds.6.4 Modules in the surround mixSince the busses are being used for the surroundmatrix channels, modules cannot be assigned to themin the usual way, and the buss keys for busses 5&6and 7&8 are disabled.However, modules can always be assigned to the ste-reo output buss.6.4.1 Assigning modulesWhen a surround mode has been selected, theASSIGN screen changes so that the buss assign-3+1 1 1 3 2 — 4 — —2 1 2 3 — 4 — —3 1 4 2 — 3 — —5.1 1 1 3 5 2 — 4 62 1 3 2 5 — 6 43 1 2 3 4 — 5 64 1 5 2 3 — 4 65 1 2 3 5 — 4 6Surround modeBuss Assign Type Output buss used for:Front LeftFront CenterFront RightRear LeftRear CenterRear RightSub
