1. Gain Adjustment Knobs: Separate gain controls for pre-amp channels A and
B adjust the output volume levels independently. Full
counter-clockwise is the minimum gain position, while full clockwise is
maximum gain.
2. VU Meters: These VU meters show output level, calibrated to correspond to digital
peak meters, where 0 VU is approximately 3dB to 6dB below clipping.
3. Clip LEDs: The Clip LED will light when that input signal is too strong and is
about to distort, or “clip” (4dB below clipping). If this LED remains lit for more
than a few moments, reduce the gain adjustment knob setting.
4. Low Cut LEDs: The "Low Cut" LED, when lit, indicates that the Low Cut
Filter switch has been engaged for the corresponding channel.
5. Hi/Lo Gain Switch: This switch will set the “gain range” (or, amount of gain
possible) for the corresponding input channel. Once the gain range is set,
gain is adjusted via the Gain Adjustment Knobs. In the “Out’ position, the gain
range is 32dB to 66dB (Hi gain). In the ‘In’ position, the gain range is 6dB to
36dB (Lo gain). See sections, “Setting the Gain” and “Hi/Lo Gain Switches”
for more information.
6. Low Cut Filter Switch: Pressing and locking this switch to the ‘In’ position
engages the Low-Cut filter for the associated channel. Pressing and releasing
to the ‘Out’ position disengages the filter.
7. Main Power LED: When the proper power supply is applied to the DMP3 and
the Main Power switch is switched to the ‘On’ position, this LED will light,
indicating that the unit is powered up.
8. Phantom Power LED: When lit, this LED indicates that phantom power has
been switched on for both of the mic pre-amp channels.
9. Main Power Switch: This switch, when pressed and locked to the ‘In’ position,
switches the DMP3 power on.
10. Phantom Power Switch: When this button is pressed and locked to the ‘In’
position, phantom power (48v) will be sent to both XLR In 1 and XLR In 2.
