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

equipment to the MN12.

 

 

 

Names and Functions

1. DC IN jack

The AC adaptor included with the MN12 is connected here.

2. Power switch

Switches ON-OFF (STANDBY) power to this mixer.

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 5-6, 7-8, 9-10 and 11-12 jacks.

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 -60dBV~-10dBV). If the PEAK LED blinks, the levels with this knob.

16. Equalizer control knobs

These knobs control the low frequency range (100Hz, +/-13dB) and high frequency range (10kHz, +/-13dB) of the input signals of INPUT 1~4 jacks.

4. AUX SEND jack

This is connected to the effector input and the

signals for effecting are controlled with the AUX

 

 

 

 

 

SEND knobs on their respective channels and

 

 

 

 

 

then output.

 

 

 

 

 

5. STEREO OUT jacks

The mixed signals is output to inputs of the MTR and Mixer. The output level is controlled with the MASTER fader.

6. LED level meter

Signals levels from the STEREO OUT jacks are indicated by these LED'S.

7. AUX RTN knob

Signals effect processed are adjusted by this knob and sent to stereo L and R.

8. PHONES knob

Adjusts sound of the headphones.

9. MASTER fader

This fader controls the signal that is output from STEREO OUT L, R jacks.

10. PHONES jack

Monitor headphone is plugged in here.

11. INPUT fader

Adjusts input level of the sound source signal applied to input jack 1-12.
