12 - Front panel—Stereo input and stereo masters12–5OUT, the direct out (where appropriate) and all post-fader Aux busses.When the active fader layer is the MASTER layer,pressing the CUT keys will cut the output busses andAux sends.If Aux busses 1 and 2 have been selected as beingpre-fader, and the CUT key of a module is pressed,signals will still be sent to Aux busses 1 and 2.The CUT indicators are also used to show inplacesolo status (all channels except the soloed channelswill be cut).[29] READ. WRITE, UPDATE indicatorsThese indicators are used to show the current statusof the module when console automation is inprogress, using an external computer.[30] Layered fadersThese faders are usually used to control the level ofthe signal of the module’s current channel, Aux sendor buss, as selected by the LAYER STATUS keys [3],hence the name “layered faders”.When the faders are “full up”, +10 dB of boost isprovided. In the “full down” position, the signals arecompletely attenuated.The AUX screens (4.5.2, “Using AUX keys to setsend levels”) also contain an option to use the fadersto control the level of the signal sent from the chan-nels to the Aux buss.The faders are motorized, but when playing backautomated mixes from an external computer, motor-ization may be turned off (2.4.1, “Turning fadermotors on and off”).12.7Stereo input and stereomasters[31] ST IN & 2 fadersThese faders are usually used to control the level ofthe signals received at the ST RTN jacks [55], as astereo pair. Note that if a connection is made to the Ljack only of one of these pairs, the channel will be amono channel.When the faders are “full up”, +10 dB of boost isprovided. In the “full down” position, the signals arecompletely attenuated.The AUX screens also contain an option to use thesefaders to control the level of the signal sent from thechannels to the Aux buss (4.5.2, “Using AUX keys toset send levels”). This is the only occasion in whichthese faders do not control the levels of the stereoinputs, regardless of the fader layer.Like the channel faders, these are motorized faders,and subject to the same restrictions and limitations asthem.[32] STEREO OUT faderThis fader is used to control the level of the stereooutput buss (both channels).When the fader is in the “full up” 0 position, the levelof the stereo output is not attenuated. For example, ifa signal is input to one channel at nominal level, andthe channel fader is at the nominal level (0), androuted to the stereo outputs with the STEREO faderat 0, the stereo outputs will be at nominal level.When the fader is in the “full down” position, the ste-reo signal is fully attenuated.[33] ALL SAFE keyThis key is used to turn off the track arming andrecording status for any external devices whose trackarming function is controlled by the TM-D4000. Seealso the REC key description [25].12.8Machine controlThe machine control section allows for control of theexternal devices connected to the TM-D4000 andselected for control.The exact degree of control depends on the deviceand on the settings made, and is described more fullyin the appropriate section on Machine control.However, a brief guide to the controls is given here,for reference. Where appropriate, you should read thedocumentation provided with the external unit for anin-depth explanation of some of the topics which arecovered briey in this manual.[34] TC/LOC indicatorsUsed to show whether the time counter [35] is cur-rently displaying the timecode received from thetimecode source, or is showing a location position ifthe appropriate Locate Display
