MP2015 MANUAL
Session Input and Output
Session input sources may be unbalanced RCA, digital S/PDIF, or USB audio channels 9/10. Session input
can be used independently to provide an additional stereo input to the mixer, or in conjunction with Session
Out to chain mixers together.
Connect any line-level device (e.g., a CD player, another DJ mixer, an iPod, iPhone, etc.) to the Session In
RCA white and red jacks. The orange S/PDIF input connects a digital device (e.g., a CDJ 2000 or another
MP2015 mixer) using a single RCA cable. Use the switch above the jacks to select the S/PDIF input or the
RCA inputs as a source. Alternatively, USB Aux audio channels 9/10 can be selected as the Session input
source using the toggle switch next to the Session In level control.
Session Output is available on unbalanced analog white and red RCA jacks and an orange digital S/PDIF
jack. These outputs can be used for auxiliary zone output, in combination with Session Input when chaining mixers together
or for external digital S/PDIF main mix recording. Both of these outputs are active at the same time.
Note: Using S/PDIF provides better sound and higher performance when connecting an available S/PIDF source like an
equipped CDJ or another mixer.
To play audio coming from a device plugged into the RCA or S/PDIF Session Inputs, set the USB AUX toggle switch
to SESSION IN (down position). To play audio from USB audio channels 9/10 set the USB AUX switch to USB AUX (up
position). To use USB AUX playback, you must assign USB channels 9/10 in your DJ or DAW software preferences panel.
Assigning the Session Input to the Submix (press the SUB button) essentially turns this 4-channel mixer into a full-
featured 5-channel mixer with the Submix channel providing independent 3-band EQ, Filter, Mix Level and Cue.
You can simultaneously record the Session Input, channels 1, 2, 3, 4, Submix, and the Main output through USB audio
channels. Multitrack recording allows you to “fix” a recording in the studio. See "USB Audio" on page 14.
The Session Out control affects the level of audio output on the Session Out RCA jacks, S/PDIF jack and USB Record
channels 13-14.
Real World Session I/O Application
If you are a Traktor and Maschine user, you may typically use a combination of four track decks and/or remix decks within
Traktor as well as hits, loops, and samples coming from Maschine.
Route your four tracks/remix decks to the four channels on the MP2015 and then route the main output of Maschine
through the Session Input via USB AUX channels 9/10. Set the audio routing in the Traktor Preferences.
Use the Session In gain to control the audio volume coming from Maschine. You can send the audio from Maschine to
the Submix by pressing the Session In SUB button, giving you full Mix level, EQ, and Filtering. Alternatively, you can take
advantage of Maschine’s discrete audio through the Deck channels to the Submix for ease of multi-source mixing and/or to
add an external effect.
Submix
The Submix is a channel that you can send any or all audio to, just as you do with the main mix. The Submix may include
any combination of the four Deck Inputs and the Session Input. Press the SUB button on any Deck or the Session In to
assign it to the Submix, lighting the button blue. This allows grouping any number of inputs for easy and intuitive multi-
source mixing. The concept is identical to a Submix or bus track on a typical audio mixing console. This capability is
important for grouping a number of tracks together onto one channel for ease of control and processing.
• Channels assigned to the Sub Mix share a common set of controls:
•
Main MIX Level.
•
3-band full-cut tone controls. Crossover points for Low/Mid and Mid/High can be changed. See "Control Panel" on
page 16.
•
16-segment Q-peak meter with peak hold.
•
Headphone CUE.
•
Selectable High-Pass / Low-High-Pass / Low-Pass Sweep FILTER.
•
Note: The Resonance control affects all Sweep Filters for Decks 1, 2, 3, 4 and the Submix.
• Assignable external Effects Loop:
•
The FX Send level can be switched on the rear panel to -10 (for low-voltage devices) or +4 (for higher-voltage devices).
•
FX ON button activates the effects loop when lit, receiving input from the FX RETURN jacks.
•
Wet / Dry controls the ratio of FX to the mix.
•
This Loop may be switched to process the Main Mix or the Submix.
• USB Record output for the Submix is on channels 11-12.
