User manual SAMSON MDR8

[. . . ] 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. [. . . ] You can create a stereo image by panning some input signals to the left and others to the right. The MDR8's PAN control is a Power-Pan circuit, which includes a 3dB dip in the center position. This is desirable since there's a 3dB increase in gain when the mono input signal is heard in both the Left and Right MIX bus. 8 9 RECORD The RECORD switch is used when operating the MDR8's HDM (HARD DISK MODE). If HDM in the master section is not engaged, the RECORD switch LED will be off and pressing the RECORD switch will have no effect. This is the normal mode of operation for most live mixing situations, however since the HDM provides some extra flexibility in signal routing, the HDM can be used for zone mixing as well. For more information on the HDM see the section "Using the HDM" on page 15 of this manual. 9 10 10 FADER The MDR8's 60mm input FADER controls the overall channel level. The input FADER features an audio taper and no detents for smooth fades. 7 Controls and Functions MASTER SECTION 2 TRACK INPUT AND OUTPUT The MDR8's 2 Track section provides the connections for playback and recording for an external device such as a DAT, cassette recorder, CD or Mini Disk. 11 2TK LEVEL The 2TK LEVEL control is used to adjust the amount of signal that is sent from the 2T IN jacks to the main L/R Mix bus. For more information see the section, "Playing back a CD Using the 2 Track to MIX" on page 15 of this manual. 12 HDM The HDM switch enables the HARD DISK MODE and is used to interface with a computer based hard disk recorder. When turned on, the channel RECORD switches are activated for special bussing and monitoring features. For more information on using HDM, see the section "Using the HDM" on page 15 of this manual. 11 15 12 24 BIT DIGITAL EFFECT SECTION The MDR8 features a built-in, 24 Bit Digital Effects processor with high quality, studio grade effects such as Delay, Chorus and Reverb. The following section describes the features of the powerful on-board DSP. 13 SELECT Switch (DIGITAL EFFECTS) The SELECT switch allows you to select one of the eight built-in digital effects. 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. This signal is summed, or mixed in to the main L/R MIX bus. 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. [. . . ] 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. Connect a microphone to the MDR'8s Channel 1 microphone input and set a proper level using the GAIN control and peak LED. The input Channel's REC LED will light dimly indicating the channel can be assigned to the RECORD bus. [. . . ]
