    AUX 1/MON SEND The MDR8 has two auxiliary sends which can be used for sending signals to the external effects devices or for creating a monitor mix. The AUX1/MON section is often used for a monitor mix in a live sound mixing, or for a headphone mix in a recording application.
  • Page 9 PAN (Mono Inputs Only) The MDR8’s PAN control is used to place or position the mono signal into the stereo main Left and Right MIX bus. You can create a stereo image by panning some input signals to the left and others to the right.

    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. 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.

    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.

    Line Level Input - Stereo Input Channels The MDR8’s stereo channels have a stereo LINE input with the Left Input located in the center of the Combie connector and a separate 1/4-inch connector for the Right Input. You can connect the outputs from stereo devices such as synthesizers, drum machines, effects processors or any stereo line-level sig- nal.
  • Page 13 EXTERNAL OUTPUT JACKS The MDR8 features several output connectors allowing you to interface a variety of external devices. A stereo recording device such as a cassette recorder can be connected to the 2 Track jacks, and additional power ampli- fiers can be connected to the CONTROL ROOM and MAIN output jacks.

    5. Set the Left and Right MIX faders in the MDR8’s master section to the "0" position. 6. While speaking into the mic (or playing the instrument), adjust the channel Fader control so that the "0" LED of the MAIN section peak level meter lights occasionally.
  • Page 15 This allows you to create a mix for the monitors that is independent of the main LEFT and RIGHT MIX. 2. In order to get the most gain from your monitor mix, use an external graphic equalizer like a Samson e31I to cut out any frequencies that cause feedback.
  • Page 16 PLAYING BACK A CD USING 2TK LEVEL The MDR8 has a dedicated input for playing back a stereo device such as a CD, Tape or Mini Disk. Below is a description of how you can play back a CD, Tape or MD using the MDR8’s 2 TRACK INPUT.
  • Page 17 Follow the examples below to use the HDM. Set the MDR8 inputs fader all the way down and the L & R MIX faders to the “0” position. For this example, we’ll first record a rhythm track sequence from a MIDI keyboard (any stereo track will do), then do an overdub.
  • Page 18 3. Engage the HDM switch in the Master Section. The input channel’s REC LED will light dimly indicating the channel can be assigned to the RECORD bus. 4.
