[. . . ] MDR Series Mixers EIGHT CHANNEL MIXER WITH 24BIT DIGITAL EFFECTS AND HARD DISK MODE Safety Instructions/Consignes de sécurité/Sicherheitsvorkehrungen/Instrucciones de seguridad WARNING: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. To reduce the hazard of electrical shock, do not remove cover or back. Please refer all servicing to qualified personnel. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. [. . . ] Simply rotate the SELECT knob to choose the various effect pre-sets. 16 13 14 14 DSP PEAK The DSP PEAK indicator lets you know when you are sending too much level to the internal effects processors. If the LED illuminates, turn down the signal from the channel's AUX 2 /DSP send. You may need to do this on more than one channel if you have multiple inputs sending to the internal DSP. 15 DSP TO MON The DSP TO MON allows you to add the internal effects to the AUX 1/ MON send. When you raise the level of the DSP TO MON control, the signal from the DSP return is mixed in to the AUX 1/ MON. You can use this to add effects to your monitor mix in a live sound mix or to your headphone mix in the studio. Effect Preset List This section identifies the eight built-in DSP effects presets. Following is the effects pre-set list: 16 8 Controls and Functions MASTER SECTION (continued) Auxiliary Returns The MDR8 has two stereo auxiliary returns, which can be accessed via the two pairs of 1/4-inch phone jacks located on the rear panel. The auxiliary returns can be used to connect any stereo line level signal, but they are primarily used to connect the output of external effects processors. The MDR8's on-board effects are internally connected to the auxiliary 2 return. 17 18 AUX RET 1 This adjusts the amount of signal that is sent from the AUX 1 RET jacks to the MAIN bus. AUX/DSP RET 2 The AUX/ DSP RET 2 adjusts the level of the signal present at the AUX 2 RET jacks. When using the on-board digital effects, the AUX/DSP RET 2 control is used to control the output level of the internal DSP effects processor, which is also summed with the main L/R MIX bus. 22 17 18 23 Output Section The MDR8 has two main outputs for listening to your stereo mix. The Left and Right Mix outputs, which, in a live sound application, you'll hook up to your power amp and PA speakers, and the Control Room outputs which you'll use to connect your powered studio monitors to in a recording application. The following section explains the controls that you will use to route the signal to feed these outputs. 24 19 20 19 MIX/2T The MIX/2T switch selects the signal source that you are monitoring in the CONTROL ROOM and HEADPHONE outputs. When the switch is in the up position, the signal source is from the LEFT/ RIGHT MIX bus. Since the signal source is now set to the Left and Right Mix bus, be sure that the Left and Right Mix faders are pushed up to feed the signal to the Control Room and headphone outputs. When the MIX/2T switch is in the down position, the signal source is from the 2 TRACK input. Since the signal source is now set to the 2-track input, be sure that the 2TK LEVEL control is turned up to feed the signal to the Control Room and headphone outputs. 20 C/ROOM + PHONES 21 The C/ROOM + PHONES control is used to set the level sent to the Control Room outputs, and also to the headphone jack. As explained in the previous section, the MIX/2T will determine what signal is sent to the Control Room and Headphone outputs. Be sure to adust the Left and Right Mix faders or 2T to Mix control to send the desired signal level to the Control Room and Headphone outputs. 21 L MIX R The L&R MIX faders are the over-all volume control for the MIX bus. The L&R MIX faders affects both the signal which is output to the CONTROL ROOM speakers and the line level signal which is output from the MIX OUTPUT jacks. Meters and Indicators 22 +48V - Phantom Power LED The +48V LED illuminates indicating that the 48 volt phantom power is applied to the microphone pre-amps enabling use with condenser microphones. The +48V LED will light up when the Phantom Power switch located on the rear panel is switched to the ON position. 23 24 POWER LED The Power LED lights up to indicate that the main POWER switch, located on the rear panel, is on. Output Level Meter The OUTPUT LEVEL METER allows you to monitor the level of the signal which is being sent to the L&R MIX OUTPUT jacks. NOTE: To avoid distortion, adjust the L/R MIX faders LEVEL control so that the 0 indicator LED lights occa- sionally. 9 MDR8 Input and Output Connections 3 1 2 CHANNEL 1­8 MIC and LINE INPUTS 4 6 7 8 5 9 The MDR8's eight input channels each have a "Combie" (combination XLR & 1/4-inch) connector with a LINE level, Hi-Z (High Impedance) input and a MIC level, Low-Z (Low Impedance) input. By using the GAIN control on channels 1-4 you can connect a variety of signal sources from microphones and direct boxes to line level devices such as synthesizers and drum machines. [. . . ] Select the record enable on the tracks you are recording to on your hard disk recorder and set a level as described in your software manual. Overdubbing Using HDM Now that you have recorded a basic rhythm track you can overdub additional tracks using MDR8's HDM. For this example, we'll overdub a vocal track using a microphone. Connect the output from your computer sound card to the MDR8's 2Track In and then connect the MDR8's 2Track Output to the input of the sound card. [. . . ]
