3 - Connections : Analog connections Analog connections Mic/line connections All these connections (microphone and line) are balanced. The XLR connections follow the standard of pin 1 ground, pin 2 hot and pin 3 cold. The TSR 1/4" jacks are tip hot, sleeve ground, ring cold (this applies to all balanced 1/4" jacks on the DM-3200). Both the XLR mic connection and the 1/4" jack connection can be made at one time, but it is only possible to accept input signals from one source at a time. The choice between the mic and line inputs is made with the MIC/LINE selector switches for each input channel Figure 3.2: Analog channel inputs and controls Note that the switch also has a -20 position, providing a 20 dB pad for high-output microphones. The analog input signal level can be adjusted using the analog TRIM controls (there is also an internal software digital trim control for each input channel, independent of these analog controls). A +48V phantom power supply is provided for balanced condenser microphones. This is switchable in groups of 4 (inputs 1-4, 5-8, 9-12 and 13-16). WARNING To avoid damage to the microphones and/or the DM3200, do not connect or disconnect condenser microphones to and from the DM-3200 with the phantom power to that input switched on. Always switch the phantom power off before connecting or disconnecting condenser microphones. Do not use unbalanced dynamic microphones connected to the XLR connectors with the phantom power turned on. This may cause damage to the microphones and/or the DM-3200. The 1/4" balanced input jacks accept +4 dBu connections, but you can use the TRIM controls to allow them to accept -10dBV connections (from synthesizers, etc.). Note that if additional analog inputs are required, the optional IF-AN/DM slot card can be used to provide such inputs. TIP Signal/overload indicators for the input channels are selectable in the preferences screen. See "OL/STATUS LED TYPE" on page 33 for full details. Channel inserts The analog inserts for each ana- log input channel allow you to use your favorite analog compressors/gates, etc. before the sound gets converted to the digital domain. NOTE These are not the same as the "soft" (assignable) insert loops which are described in "Insert patching" on page 50. These 1/4" jacks are wired: tip send, ring return, sleeve common ground. The nominal send and return levels of these inserts is -2 dBu which allows them to be used with a wide range of studio equipment. 2 TR IN This pair of unbalanced RCA jacks pro- vides a -10 dBV return for the analog outputs of a 2track recorder connected to the DM-3200. ASSIGNABLE RETURNS These are balanced 1/4" TRS jacks at +4 dBu (wired as described above). As the name suggests, they provide analog return inputs which can be assigned to a variety of sources (see "Routing" on page 47). TASCAM DM-3200 User's Manual 39
