Whether recording in the studio or performing live on stage, the Radius

10 will add great life to even the cheapest of dynamic microphones,

producing a more rounded, open sound which compares favourably with

the quality of expensive tube condenser microphones. With four channels

of high quality tube mic pre amplification, vocals and instruments are

instantly warmed, with the extra presence loved by artists and recording

engineers alike. Each channel features input and output level controls,

swit48V phantom power, phase reverse and a 90Hz high pass

filter, ensuring each signal may be quickly and easily processed, adding

the required level of rich, harmonic overtones associated with vacuum

tubes. Drive and peak LEDs indicate the operational status of these twin

stage tubes, displaying at a glance whether they are being driven at their

optimum level. This, coupled with variable input and output gain, means

that signal levels through the tubes may always be optimized.

KEY FEATURES

Four channels of high quality mic pre amplification.

Balanced XLR mic inputs, with both XLR and

unbalanced jack line outputs.

Variable control of input and output gain allows

optimum signal level through tubes.

Switchable 90Hz high pass filter.

Swit48V phantom power for connection of

condenser microphones.

Phase reverse switch allows instant phase correction

for each input signal.

Drive and peak LEDs indicate the degree of tube

warming and warn of low headroom.

Twin stage triode vacuum tubes.

Stabilised 150V DC power supply.

High performance tube processing used to be the exclusive domain of big budget

recording studios and live sound productions. Not any more. The HHB Radius

Series combines innovative British professional audio design with the finest

components and exacting manufacturing standards to create a range of tube

outboard equipment in which price is the only corner we’ve cut. The HHB Radius

Series consists of a mic pre amp, a four band stereo EQ, a compressor, a voice

processor and a mic pre amp / compressor, bringing the unique warmth and

presence of the vacuum tube to all kinds of recording, mixing, mastering and

performance projects, large and small. Signal interfacing includes balanced XLRs

and unbalanced jacks, making it easy to incorporate Radius processors into your

existing setup, and the clear, consistent layout of the controls means that you’ll be

adding the magic ingredient of an HHB Radius tube processor to your music,

straight out of the box.
