Overview
The Radial PowerTube is a vacuum tube amplifi er designed to elevate the relatively low
level signal of a microphone to a +4dB professional line level. Once at line level, the signal
can then be processed by a various pieces of equipment such as compressors, limiters and
equalizers or be sent to the line level input of a recording system.
BALANCED
INPUT
Like most mic preamps, the PowerTube features common functions such as a mic input, trim
control, gain control and 48 volt phantom power. Some of the extras that are not so common
include a 10 bar LED VU meter, polarity reverse switch, a high pass fi lter and an air control
for added presence. Some of the truly unique features include the use of a premium Jensen
input transformer, fully discrete class-A output buffers and of course a select 12AX7 tube.
Together these features truly deliver more than the sum of their parts. And we are confi dent
that once you start experimenting, you fi nd the PowerTube will sound absolutely amazing in
just about any situation.
