The front panel of the BLUETUBE DP has analog VU meters for channel
1 and 2 to the far left and far right respectively, which measure the input
level. VU stands for ' volume unit' , which is an average measurement of
the input signal level. This means that not all transients will be displayed
by the VU meter.
Both preamp channels contain:
+48V Switch
Polarity Reversal Switch
-20dB Pad
80Hz Filter
Gain Control (0 to 54dB)
Tube Drive Control (0 to100%)
