The Radial H-Amp is a unique passive interface that takes any loudspeaker signal and converts it to a headphone source.
Designed for live stages, the H-Amp is the an interface that allows,
for example, a drummer to get a monitor feed from any loudspeaker!
Using the ‘through’ connection from a wedge monitor or side fill,
the H-Amp is equipped with a Neutrik Speakon connector input and
converts the high level loudspeaker signal to a mono feed for
It features a variable level control, high pass filter to remove
excess low-end, a variable tone control to smooth out the highs plus a
selector switch to enable various headphone types with wide ranging
impedance as well as in-ear monitors to be connected. Choice of mono
TRS out for standard headphones and mini 3.5 mm jack for ear buds.
A second Speakon provides a throughput to feed a second H-Amp
opening the door for applications such as in the studio or on concert
stages where multiple members of the orchestra may need a headphone
The H-Amp is 100 percent passive. Because it only taps a small
portion of the signal, it will not affect the amplifier’s impedance or
load making it easy to use without any system reconfiguration. All you
do is plug and play! It also works great with a power amplifier.
It is designed to handle the rigors of professional touring, with a
14-gauge steel welded internal I-beam frame with an outer book-end
design that provides a protective zone around the connectors, switches
and potentiometers plus a full-bottom no-slip pad.
