14 – Surround operations—“Pan” controls110 TASCAM DM-24 Reference Manualtings—each module’s (or channel’s) position in thesurround image is set independently. However, thefact that these modules have been linked is shown bya & following the module number at the top of thescreen.To change the module to be edited, use the SEL keyof the channel to be edited.Each channel is shown as a “dot” cursor on a plan ofthe current surround mode.The crossing point of the cursor (i.e. the position ofthe module signal in the surround mix) can bechanged with the knobs of POD 1 and POD 3 (theseadjust the left/right position for the odd and evenmodules) and the knobs of PODs 2 and 4 are used toadjust the position from front to rear. These adjust-ments are made when the row cursor is highlightingthe top row on the screen.For the left/right settings, there are 201 steps, so theleft/right setting goes from L through L99 through C(center) through R99 to R. The front/rear settings gofrom F50 through C (center) to R50.There is another parameter, which determines theamount of the total “sound-stage”, taken from thecenter position, within which the module signal canbe positioned. This is set using the second row of on-screen PODs.The values here are set in 4 steps: 25% (the mosttightly focussed, almost a point source near the cen-ter), through 50% and 75% to 100% (the whole of thesound-stage is available).Using these parameters, it is therefore possible to setthe position of a signal precisely or loosely in eitherdimension.Note also the “bar-graphs” (not meters) by each on-screen speaker, which give an indication of the rela-tive level of the signal to each of the output channelsin the surround matrix.In addition to these positioning controls, in the 5.1surround mode the sub-woofer level (BOOM) may beset with the knobs of PODs 1 and 3 using the bottomon-screen row of PODs.Pods 2 and 4 of this row are used to move the signalsource diagonally within the surround area (equiva-lent to turning the L-R and F-R pan controls simulta-neously). The diagonal angle is set using the on-screen buttons.Global boom levels (5.1 only)In addition to the individual levels which may be setfor the bass speaker (BOOM), there is a global pagewhich allows this level to be viewed and edited for allchannels simultaneously:NOTEThis screen is only available in 5.1 mode, as it only hasany meaning in this mode.1 While in the SURROUND screen, press soft key3 to bring up the boom level display.2 Use the cursor keys to select groups of fourchannels.3 Use the PODs to edit the levels of the fourselected channels.To set the levels of many channels together:1 Move the cursor to the bottom row of thescreen.2 Use POD 2 to change the selection groupbetween ALL (all channels), ODD (odd-num-bered channels), EVEN (even-numbered chan-
