Important Notes in Operation
* Avoid using headphones for long hours at high volume levels.
Doing so can result in hearing failure. Any sudden increase in headphone sound levels must also be avoided. This could result in damage to your hearing.
*Turn down all sound volume controls when switching on power to this mixer.
Also, turn all volume controls when switching on/off power to the MN12. Otherwise, a sudden loud noise could have a bad affect on you ears and your hearing.
*Turn down the sound volume control when plugging or unplugging the headphone into the PHONES jack.
Always turn down the sound volume control when connecting or removing the headphone plug from the PHONES jack. Doing so with the volume control turned up, could result in hurting your ears.
Connecting the AC adaptor
Plug the AC adaptor cable into the MN12 DC IN jack and plug the AC adaptor into the wall outlet.
<NOTE>
Unplug the AC adaptor from the wall outlet if the MN12 is not to be used for long hours or extensive periods of time.
The schematic is indicates that the outer sheath is minus polarity, and the power supply is DC 12V.
* Switch off power to the mixer when interconnecting it to external equipment.
Always be sure to switch off the MN12 power when interconnecting external | DC IN | |
| 12V | |
equipment to the MN12. |

3. AUX RTN jacks
This is connected to the effector output and the effector processed signals sent to the stereo L, R connectors. Input signals are adjusted with the AUX RTN knob. If the effector output is stereo, they are respectively connected to L and R, and if output in mono, it is input to L/MONO.
12. INPUT jacks
External sound sources are input here.
INPUT 1~4 complies to mic/line and levels controlled with the TRIM knobs to match the input. INPUT 5~12 are exclusively for line level inputs and are in stereo. If monaural sound sources are to be input, they should be connected to the MONO marked 5, 7, 9 and 11 jacks, and for stereo, to the
13. AUX send knobs
The AUX send knobs determine the level of the input signal that will be sent to AUX SEND jacks. The signal adjusted by these knobs can be sent to an external device, such as an effect unit.
14. Panpot knobs
Adjusts the sound position when signals input to each input jack is output to the STEREO OUT (L, R) jacks.
15. Input trim knobs
These are adjusted to match the output level of the sound sources connected to INPUT 1~4 (adjusting range is
