VU Meter.

your BlueTube DP V2.
48 Volt Phantom Power.

phantom power to the XLR input. Here is the XLR
connector wiring for phantom power:
Pin 1 = GND
Pin 2 = +48V
Pin 3 = +48V
Phase Reverse.
Reverses the polarity of the signal.
Use Phase Reverse to combat phase cancellation
between microphones.
-20 dB Pad.
This button attenuates (lowers) the input
signal by 20 dB. The pad can be used to keep a hot
signal from overdriving the microphone preamp.
80Hz Roll-off.
The 80Hz button is a low-end roll-off
filter. When depressed, this button causes all
frequencies below 80 Hz to be attenuated (dropped)
by 12 dB. This filter can be handy in live and studio
applications. For example, the 80Hz filter can help to
reduce the “boominess” or “muddiness” of a vocal and
can improve the overall clarity.
