HM band - 1kHz and 12kHz,
HF band - 3kHz and 20kHz.
•
EQ bypass switch for each channel.

KEY FEATURES
•
Two channels of variable ratio tube compression.
•
Balanced and unbalanced line inputs and outputs with
gain controls.
•
1/4" jack instrument inputs on the front panel.
•
Sidechain inserts for frequency controlled compression.
•
Variable threshold, compression ratio and gain make-
up for each channel.
•
Drive and peak LEDs indicate the degree of tube
warming and warn of low headroom.
•
Stereo link mode for compressing stereo signals.
•
Compressor bypass switch.
•
Variable threshold control on the expander / gate helps
reduce noise during quiet sections in the signal. The
red LED indicates when this gate is closed.

VU monitoring of output level or gain reduction.
•
Stabilised 150V DC power supply.
The Radius 20, with its combination of solid state circuitry and vacuum
tube technology, will not only alter the sound of an input when required,
but also improve its tonality, ensuring every instrument or mix sounds
just the way it's intended to. Drums become tighter and more punchy,
guitars are made to cut through any texture, and many different vocal
effects may be achieved, limited only by your imagination. Four bands of
fully parametric equalization provide complete control. With variable gain,
frequency and bandwidth, the Radius 20's comprehensive controls are
designed for familiarity and ease of use. And with the addition of an EQ
bypass switch, any added equalization may be removed for instant A/B
signal comparison. Both channels feature a front panel 1/4" jack
instrument input so that, when rack mounted in the studio, the Radius 20
is quickly accessible. Overall levels are managed by the input and output
gain controls, controlling the amount of tube effect required.
With two separate channels of compression, the Radius 30 will soon
become an indispensable part of your studio setup, adding the finishing
touch to the sound of individual instruments or compressing an entire
stereo mix. Vocals take on a different character when compressed - quiet
singing becomes incredibly intimate thanks to the unique combination of
the Radius 30's tube technology and solid state circuitry. Even screaming
vocal lines are controlled; only the tone of the voice shows the true
levels. Backlit VU meters for each channel monitor either the output level
or the amount of gain reduction. The Radius 30 has all the benefits of the
vacuum tube without the additional noise, due to HHB's unique
transconductance amplifier design which avoids using VCAs. With control
of input and output gain for each channel, and variable threshold, ratio,
gain and attack / release times, the Radius 30 will control and compress
every input to your exact requirements, without missing a single beat.
