TASCAM DM-24 Reference Manual 7310 – MonitoringThe DM-24 contains a sophisticated monitoring sys-tem which allows different mixes to be set up in thecontrol room and the studio, as well as an integraltalkback microphone, lineup oscillator, etc.Control room monitoringThe control room (CR) monitoring section, whichalso includes two stereo headphone jacks, is locatedto the right of the stereo meters.Control room outputsAs might be expected, the control-room output sig-nals are always output from the balanced 1/4” analogCR (BAL) connectors (+4dBu) 6.However, if the digital outputs are not being used forany other purpose, the I/O OUTPUT screen may beused to assign the control room outputs to either theDIGITAL 1 or DIGITAL 2 sets of outputs.From the I/O screen, use the third soft key to bring upthe output selection screen.Move the cursor to either of the selection boxesopposite the DIGITAL OUT1 or DIGITAL OUT2 selector.Turn the dial until C.ROOM is shown, and pressENTER.The control room signal will now be output from theselected digital outputs.NOTEThe signal is sent from both the XLR-type jack and theRCA jack simultaneously. The output format (AES/EBUor SPDIF) is set using the DIGITAL display FORMAT sub-screen.The level of the signal sent from the analog outputs isadjusted by the CR control.The level of the signal sent from the headphone jacks(both headphone jacks together) is adjusted using thePHONES control.Control room signal selectionThere are four signal selection keys for the controlroom signal.These are: STEREO, SEL 1 (AUX 1-2), SEL 2 (D IN1), SEL 3 (2 TR IN).The first of these, STEREO, is hard-wired. That is,when this option is selected, the control room outputsas selected above will always output the stereo busssignal.The other three keys are “soft”, and may be patchedinternally to output signals other than those given asthe defaults (in parentheses on the panel).The default settings may be useful when used in thefollowing way, however:When recording, aux sends 1 and 2 may be used asthe studio cue mix, leaving aux sends 3 through 6 foreffect use, etc. By using the SEL 1 key set to thedefault AUX 1-2 setting, it is therefore possible forthe control room monitor to echo the signal sent tothe studio.When mixing, the mastering devices (connected tothe stereo buss) may be digital or analog. The SEL 2key is by default set to the first digital input (whetherthis is the XLR-type connector or the RCA jack isdetermined in the channel IN screens of the I/O setup)and can therefore be used for monitoring the replayfrom the digital 2-track mastering device.The SEL 3 key is by default assigned to the analog 2-track inputs 9. These are typically used to monitor
