IMPORTANT NOTES IN OPERATION
1. 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.
2. 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 MN04. Otherwise, a sudden loud noise could have a bad affect on you ears and your hearing.
3. 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.
4. Switch off power to the mixer when interconnecting it to external
equipment.
Always be sure to switch off the MN04 power when interconnecting external equipment to the MN04.
5. Properly dispose of exhausted battery removed from the mixer.
Do not throw old battery removed from MN04 into a fire. This is very dangerous as they could explode.
6. Use an AC adaptor specified by Fostex.
Be sure to use the AC adaptor specified by Fostex. The power cord connector polarity could be wrong depending on the manufacturer.
The schematic is indicates that the outer sheath is minus polarity and the inner pole plus
DC IN polarity, and the power supply 9V is DC 9V.

Peak LED
This LED will be lit when the output signal adjusted by the master fader overloads. Set the master fader so that the LED dose not light too frequently.
Master fader
Pan pot knob
Adjusts the sound position when signals input to each input jack is output to the STEREO OUT jacks.
Input fader
Adjusts input level of the sound source signal applied to input jacks 1~ 4.
Input jacks 1 ~ 4
External sound sources such as mic, keyboard, guitar, etc. are plugged here. As a level selector for mic/line is provided in channel 1, this should be used when connecting a microphone. Line level output signals only should be connected to channels 2 ~4 as these jacks are designed for line output sound sources.
Final level of the mixed signal output to the STEREO OUT jacks are adjusted with this fader.
The headphone sound level is also adjusted by this fader.
PHONES jack
Monitor headphone is plugged in here.
