The H-Amp is a novel device equipped with two Neutrik Speakon connectors. One merely takes the ouput from a loudspeaker like a wedge monitor, connects it to the H-Amp and it automatically converts 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. 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 using more Speakon NC4 cables.

Each output is equipped with a separate level control plus 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 allows sufficient control to help accentuate certain frequencies for improved audio.

Like all Radial products, the H-Amp is designed to endure the abuse of professional touring. 14 gauge steel construction throughout provides excellent shielding while the I beam internal frame ensures the PC board is stress free. The innovative book-end construction provides a protective barrier around the switches, controls and connectors further lengthening life span. Plus a full bottom no-slip pad provides both mechanical isolation and electrical insulationy.
