noise performance and wide dynamic control. This gives
the BLUETUBE DP the ability to boost your signal
without increasing unwanted background noise.
?
Phantom Power.
Each channel of your BLUETUBE
DP has 48V phantom power available. When the
phantom power switch is engaged on either channel,
power is supplied at a constant rate to that channel. This
assures optimum performance of your condenser
microphone(s) and that the signal will be free of
distortion due to insufficient power.
?
Polarity Reversal.
A polarity reversal switch is provided
on each channel. This switch enables the user to invert
the polarity of a microphone if phase cancellation is
noticed when using identical microphones in close
proximity to one another. The polarity reversal switch
also can compensate for different XLR connector hook-
ups where pin connections have been inverted.
?
-20dB Pad.
A -20dB pad is available on each channel
for reducing the in-coming signal level. This pad
provides a more manageable signal from high output
devices giving the operator greater control over the in-
coming signal and a much reduced chance of over-
driving the input and thereby avoiding distortion.
?
80Hz Filter.
A rumble filter is available to eliminate low
frequency noise. This lets you greatly reduce
background noise such as air conditioners or wind noise
with the flick of a switch without effecting the desired
frequencies.
?
Mic/Instrument Input.
Each channel of the BLUETUBE
DP has a separate Neutrik Combo
?
XLR / ¼ inch
connector is provided on the back of the chassis for
signal input from microphone XLR or instrument ¼ inch
