2 – User interface—Fader layers18 TASCAM DM-24 Reference ManualWhen two aux channels are linked together, theencoders work in a slightly different way for theselected channel. The first encoder (GAIN) controlsthe pan for the first two aux sends (1-2 or 5-6) andthe second (FREQ) controls the level for these sends.The third (Q) and fourth (PAN) control the pan andlevel respectively for aux sends 3-4 in the first AUXencoder setting (they have no effect in the secondAUX encoder setting).The operation of the pan settings is as described forchannel operations (“Encoders used as pan controls”on page 17).Fader layersThe DM-24 has sixteen physical “channel” fadersand one master fader. However, it is capable ofaccepting more inputs than faders (up to 32 chan-nels), and also has eight output busses and six auxsends, which are often controlled on conventionalmixers using their own faders.To allow the sixteen faders to control the differentparts of the console, the faders are arranged in “lay-ers”. The layers are arranged as follows (as shownabove each fader on the console itself):Use the LAYER STATUS keys located to the right ofthe master fader, to switch between the three faderlayers. The selected key lights and the keys are of dif-ferent colors, as shown in the table above, so that it iseasy to see which layer is currently active, even froma distance.These fader layers also affect the use of the moduleREC keys (used for arming the tracks of externalcontrol devices), the SEL keys, and the MUTE keys.When the fader layer is selected, the faders move toshow the current status of the layer.Machine control keysAs well as the keys controlling the DM-24 functions,there are also dedicated keys to control externaldevices connected to the DM-24.Among these keys there are dedicated transport keyswhich allow basic transport control, as well as con-trols for auto punch and repeat control of externaldevices.There are also REC keys at the top of each channelstrip, which are used to arm tracks on a connecteddevice.See “Machine Control/Location” on page 80 for fulldetails.A strip of location keys to the right of the displaymode keys controls the location facilities on the con-nected machine. When these keys are used for loca-tion, the DISPLAY MODE keys take on theirNUMERIC ENTRY functions. The digits entered withthese keys are labelled at the left of the keys.These keys are also used to enter digits when namingor renaming library entries (“Setting and editingtitles” on page 101).Automation keysThe DM-24 has self-contained automation facilities.The dedicated keys to control these functions are allcolored purple for easy identification.These keys are the AUTOMATION block by the trans-port controls, and the purple key near the rotaryencoders.There is a separate “shift” key to control the secondfunction of some of the automation keys (and theLAYER 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Ma1–16 1 2 3 4 5 6 7 8 9 10 11 12 13 15 15 16 M17–32 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 MMASTER B1 B2 B3 B4 B5 B6 B7 B8 A1 A2 A3 A4 A5 A6 — — Ma.
