Settings for the Analog Inputs
■ Pad
Pressing either of these switches attenuates the MIC IN input signal by 20 dB. You use these at times such
as when devices other than microphones are connected. Press them again to cancel.
■ Sensitivity (SENS)
These adjust the input sensitivity. You can perform adjustments within a range of -64 dBu to -16 dBu
(within a range of -44 dBu to +4 dBu when PAD is depressed).
When a microphone input has nothing connected to it, it may be a good idea to press the
PAD switch and leave the SENS control set at +4 dBu. This suppresses the amount of noise
sent to the unit.
■ Peak Indicator
The peak indicator lights up when the input level from microphone input jacks exceeds the value set for PEAK.
At the factory default setting, it lights up at -3 dBu. To change this, follow the steps below.

1. Press the [SYSTEM] button several times to display “PEAK.” The button lights
up in orange.
2. Turn the center Value control to change the settings.
“ 0 dB”:
The indicator lights up when the input sound is distorted.
“-3 dB”: The indicator Lights up at -3 dB from the level at which sound will distort.
“-6 dB”: Lights up at -6 dB from the sound-distortion level.
■ Phantom Power (+48V)
These switch the phantom power supply on and off. When a condenser microphone or other microphone
that requires a power source is connected to the corresponding MIC IN jack, set this to “ON.”
Phantom power is not supplied to 1/4 inch TRS phone jacks. If your microphone requires
phantom power, please connect it to XLR jacks.
Turn this on only when a condenser microphone requiring a phantom power source is
connected. Otherwise, leave it off. Supplying phantom power to a dynamic microphone or
audio playback equipment may cause malfunction, so carefully check the documentation for
the connected device and make the setting accordingly. (The spec for the phantom power
source for this unit is DC 48 V and 7 mA when the output is shorted.)
The phantom power source of MMP-2 can drive Condenser Microphones with electrical
specification 6.0mA or lower at 48V. Microphones that require more ampere is not
supported. Please use phantom power supply devices separately.
To prevent hazard or damage, ensure that only microphone cables and microphones designed to
IEC-268-15A are connected.
Afin d’eviter tout risque ou dommage, ne brancher que des cables de microphone et des
microphones conformes a la norme IEC-268-15A.
* The unit is designed not to produce noise when switching the phantom setting, but just to be on the safe side,
turn down the volume level before switching the setting.

1. Press the [PHANTOM,PHASE,LO-CUT] button to display “+48V.”
2. Use the left Value control to switch between “ON” and “OFF.”
3. Press the [ENTER] button to confirm your selection.
