Introduction Congratulations on your purchase of the Samson MDR16 mixer! The MDR16 is a sixteen-channel mixer, with sixteen low noise microphone pre-amps, four output buses and built-in 24 BIT DSP effects processor. The MDR16 features eight mono Mic/Line input channel strips with a three-band, mid-sweep equalizer plus a low cut filter for setting just the right tone on your microphones or instruments.

Front Panel Layout 1 CLIP – Red LED will illuminate, indicating when the GAIN , EQ, or channel fader control has been adjusted too high. 2 GAIN – Used to set the input level of the mic pre and line input. 3 HIGH FREQUENCY - Controls the high band level of the Channel Equalizer, +/- 15 dB. 4 MID CUT & BOOST - Controls the level of mid-range ,+/15 dB at the frequency set by the Mid Frequency control.
Front and Rear Panel Layout MONO OUT – The Left and Right main Mix outputs are summed together to a monaural signal and sent out this connector. 66 OUTPUT 4 FADER – Used to control the overall volume of the bus 4 mix output. 44 EQ IN/OUT – When pressed in, the Amber LED will illuminate indicating that the Graphic Equalizer is active. 67 OUTPUT 3 FADER – Used to control the overall volume of the bus 3 mix output.
Controls and Functions MONO INPUT CHANNEL SECTION The following section details each part of the MDR16ʼs MONO INPUT CHANNELS including the GAIN control, CLIP LED, 3-BAND EQ, AUX sends, PAN and LEVEL controls. The input channels one through eight on the MDR16 feature high quality, discrete transistor pre-amps providing transparency and extended dynamic range.
Controls and Functions (MONO INPUT CHANNEL CONTINUED) 8 � AUX 1 SEND � The MDR16 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 application, 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 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 MDR16 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) in the master section above the 3 /4 OUTPUTS faders, allowing you to subgroup channels. In this mode, you can assign channels to the 3/4 bus and use the 3/4 OUTPUT faders to sub-mix those channels. More information on the 3/4 to MIX switch can be found later in this manual. 23 MUTE 3/4 OUTPUT ASSIGN Switch The MUTE 3/4 switches are used to assign the channels to the 3/4 stereo bus.
Controls and Functions MASTER SECTION (continued) 24 BIT DIGITAL EFFECT SECTION The MDR16 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. 29 Effect Preset List This section identifies the eight built-in DSP effects presets.
Controls and Functions MASTER SECTION (continued) Auxiliary Returns The MDR16 has two stereo auxiliary returns, which can be accessed via the two pairs of 1/4-inch phone jacks located on the top 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 MDR16’s onboard effects are internally connected to the Aux RET2.
Controls and Functions MASTER OUTPUT SECTION - continued 41 42 SOLO Switch (1/4 Bus Output) You can listen to the signal from the channels assigned to 1/4 Bus Output in the SOLO bus by pressing the SOLO Switch located above the 1/4 Bus Output Faders. When engaged, the yellow LED illuminates indicating the channel is assigned to the SOLO bus. The SOLO switch has a “momentary” action, so pressing the switch repeatedly will assign the 1/2 Bus Output on or off the SOLO bus.
Controls and Functions MASTER OUTPUT SECTION 48 MIX/2TK The MIX/2TK 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. When the MIX/ 2TK switch is in the down position, the signal source is from the 2 TRACK input. 49 SOLO LEVEL 50 51 You can adjust the overall volume of the SOLO bus by using the SOLO LEVEL control knob.

MDR16 Input and Output Connections EXTERNAL OUTPUT JACKS The MDR16 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. 6 7 1/2 OUTPUT In a live sound application, the 1/2 bus outputs are connected to a power amplifier or powered speakers.
Operating the MDR16 BASIC OPERATION The following section explains the basic operation of the MDR16. CONNECTING MICROPHONES AND INSTRUMENTS 1. Before connecting mics or instruments, make sure that the power of all your system's components including the MDR16 is turned off. Also, make sure that the Left and Right MIX faders are turned all the way down.
Operating the MDR16 USING THE DIGITAL EFFECTS The MDR16 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 MDR16 USING THE CHANNEL INSERT JACKS To further control your signal, channels 1-8 on the MDR16 feature an insertion point, or “effects loop”, on one 1/4-inch phone jack, INSERT SEND and RETURN. An insertion point is a patch-point that interrupts the signal, allowing you to bring that signal outside to be processed by another device. You can use these connections to interface an external signal processor like an equalizer, compressor, noise gate, reverb and other audio devices.
Operating the MDR16 USING AN EXTERNAL EFFECT If you prefer to use an external device for effects processing, you can easily connect the unit using the MDR16 EFX bus disconnecting the internal DSP.
