Controls and Functions MONO INPUT CHANNEL SECTION The following section details each part of the MDR10’s MONO INPUT CHANNELS including the GAIN control, CLIP LED, 3BAND EQ, AUX sends, PAN and LEVEL controls. The input channels one through six on the MDR10 feature high quality, discrete transistor pre-amps providing transparency and extended dynamic range.
Controls and Functions (MONO INPUT CHANNEL CONTINUED) 8 8 AUX 1 SEND The MDR10 has two auxiliary sends which can be used for sending signals to the external effects devices or for creating a monitor mix. The AUX1 section is often used for a monitor mix in a live sound mixing, or for a headphone mix in a recording application. Each input channel includes an AUX 1 send which controls the amount of that channel’s signal that is sent to the AUX 1 bus.
Controls and Functions (MONO INPUT CHANNEL CONTINUED) 12 SOLO Switch When engaged, the yellow LED illuminates, indicating the input channel is assigned to the SOLO bus. The SOLO switch has a “momentary” action that activates a logic control switch. Pressing the switch repeatedly will assign the input channel on or off the SOLO bus. You can use the SOLO LEVEL control to adjust the overall volume to the SOLO Bus.
Controls and Functions (STEREO/DUAL-MONO INPUT CHANNEL CONTINUED) CHANNEL EQUALIZER The MDR10 Stereo/Dual-mono input channels feature a 2-band equalizer allowing you to adjust the high and low frequencies independently on each channel. The channel’s frequency response is flat when the knobs are in the "12:00" position. Rotating the knob towards the right will boost the corresponding frequency band by 15dB, and rotating it towards the left will cut the frequency by 15dB.
Controls and Functions (STEREO/DUAL-MONO INPUT CHANNEL CONTINUED) as mute switches to turn the channel on or off. In recording applications, you can use 3/4 switches with left and right panning to assign a channel to the either the 3 or 4 bus outputs for sending to an input of a recorder.You can also mix the 3/4 bus with the LEFT and RIGHT mix bus by using the 3/4 to MIX switch, located in the master section above the 3 /4/ OUTPUTS faders, allowing you to subgroup channels.
Controls and Functions MASTER SECTION (continued) AUXILARY SECTION - continued 27 FX TO AUX 1 The FX TO AUX1 allows you to add the internal effects to the AUX 1/ MON send. When you press this switch, the signal from the DSP return is mixed in to the AUX 1. You can use this to add effects to your monitor mix in a live sound mix or to your headphone mix in the studio. 28 FX RETURN 1 This adjusts the amount of signal that is sent from the FX RET 1 jacks to the MAIN bus.
Controls and Functions MASTER OUTPUT SECTION 35 SOLO LEVEL You can adjust the overall volume of the SOLO bus by using the SOLO LEVEL control knob. The SOLO LEVEL is active when any SOLO button is engaged. 36 3/4 to MIX Switch When the 3/4 to MIX switch is engaged the green LED will illuminate letting you know that the mix from the secondary, 3/4 stereo bus will be summed, or mixed together, with the main LEFT and RIGHT mix.
MDR10 Input and Output Connections 5 11 12 3 1 9 6 10 4 2 7 8 CHANNEL 1–8 MIC and LINE INPUTS The MDR10’s input channels 1 - 6 each have an XLR MIC level, Low-Z (Low Impedance) input and a 1/4-inch LINE level, Hi-Z (High Impedance) input. By using the GAIN control on channels 1- 6, you can connect a variety of signal sources from microphones and direct boxes to line level devices such as synthesizers and drum machines. All the LINE and MIC inputs are balanced.
MDR10 Input and Output Connections EXTERNAL OUTPUT JACKS The MDR10 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 power amplifiers can be connected to the CONTROL ROOM and MAIN output jacks. 5 LEFT/RIGHT MIX In a live sound application the LEFT/ RIGHT MIX outputs are connected to a power amplifier or powered speakers.
Operating the MDR10 BASIC OPERATION The following section explains the basic operation of the MDR10. CONNECTING MICROPHONES AND INSTRUMENTS 1. Before connecting mics or instruments, make sure that the power of all your systems components including the MDR10 is turned off. Also, make sure that the Left and Right MIX faders are turned all the way down. 2. Connect the cables to your microphones and instruments, and insert the other end of the cable firmly into the appropriate input on the MDR10.
Operating the MDR10 USING THE DIGITAL EFFECTS The MDR10 features a built-in, high quality, 24 BIT Digital Signal Processor offering studio grade effects. The DSP features clean Delay, lush Reverbs and multi-effects such as Chorus + Delay or Chorus + Reverb. The following details the operation of the internal DSP effects: 1. Connect a mic or instrument to the desired channel, and adjust the volume and equalizer to your liking. 2. Now select the desired preset on the DSP selection switch.
Operating the MDR10 USING AN EXTERNAL EFFECT If you prefer to use an external device for effects processing, you can easily connect the unit using the MDR10 EFX bus disconnecting the internal DSP. Follow the simple steps below to interface your processor: 1. Connect the AUX 2 OUTPUT to the input of the external effect processor. 2. Connect the outputs of the effect processor to the FX RETURN 2 located on the MDR10’s top panel. 3. Set the L/R mix faders to the "0" position. 4.
This system shows the MDR10 connected to a pair of powered speakers like the SAMSON dB500a. The AUX 1 is connected to an external power amp, which is driving 2 monitor speakers. For inputs, two microphones are connected to channels 1 and 2’s low-impedance inputs, and the output of the Bass Direct Box is also connected to the low-impedance input on channel 4. The Keyboards, as well as the Lead and Rhythm Guitar signal processor's outputs, are connected to the MDR10’s line inputs.
N 21 R This system shows the MDR10 in a recording set up with the LEFT and RIGHT CONTROL ROOM output hooked up to powered studio monitors and the AUX 1 feed headphone mix, sent to a Samson S phone headphone amp. For inputs, two microphones are connected to channel 1 and 2’s lowimpedance inputs, and the output of the Bass Direct Box is also connected to the lowimpedance input on channel 4.
MDR10 Wiring Guide CONNECTING THE MDR10 The are several ways to interface the MDR10 to support a variety of applications. The MDR10 features balanced inputs and outputs, so connecting balanced and unbalanced signals is possible.
