Updated from its original specs, the new Radial Engineering Radial H-Amp speaker to headphone converter is now shipping.

The H-Amp is a speaker to headphone converter equipped with two Neutrik Speakon connectors. According to the manufacturer, all you have to do to use the H-Amp is take the output from a loudspeaker like a wedge monitor, and connect it to the H-Amp. It will then automatically convert the speaker signal to a safe level, producing a mono output for headphones.

The production version of the H-Amp has been upgraded from one output to two, enabling two musicians to share the same feed. Radial Engineering notes that because the H-Amp is also able to be driven directly from a power amplifier, multiple H-Amps can be used in series by connecting through more Speakon NC4 cables.

Each output is equipped with a separate level control, and a three-band filter set can be inserted into one of the headphone outs to alter the signal should two different types of headphones be connected at the same time. This capability allows sufficient control to help accentuate certain frequencies for improved audio, according to Radial.

Like all Radial products, the H-Amp is designed to endure the stresses of professional touring. It has 14-gauge steel construction throughout, which provides shielding, while the I beam internal frame ensures that the PC board is stress-free. The H-Amp's book-end construction provides a protective barrier around the switches, controls, and connectors, further lengthening the life span of the unit. In addition, a full bottom no-slip pad provides both mechanical isolation and electrical insulation.

About the H-Amp, Radial Engineering's president, Peter Janis, said, "The redesigned H-Amp is one of those products that had unfortunately, been 'backburnered' pending completion of other products. Several of our professional touring customers have been waiting on this product release. They can see the merit of being able to take any speaker feed and quickly convert it so that it can feed a headphone. Well the wait is over, we have worked through the various designs and have come out with a new spec that we believe will address the concerns that were voiced when we showed some of the early prototypes."
