Hertz ML 280 [10/36] Technology

The possibility to choose among different configurations and MILLE crossovers extreme

versatility forced us to design a switching system easy to use, with long-term reliability, which

could provide first-grade contact. The EJ's, Easy Jumpers, are naturally ergonomical and ensure

colorless acoustic performance.

Crossovers are often the core of spectacular installations. We therefore designed a chassis which

combines vibrations rejection, finishings resistance and thrilling look.

Your eyes can enjoy the filters die-cast aluminium central chassis, their transparent perspex top

cover, the connections controls Shiny finishing, as well as the patient, careful assembly of the

internal components. They are wondeful to look at, as well as extraordinary to listen to.

Manufacturing and components quality is very important. In HERTZ laboratories, we doubted

about every acquired certainty and reconsidered every component as if it were the first time, in

order to set new standards. We measured, listened to, compared the most valued components.

The wonderful Quadralitz inductors used in woofers and midranges crossover networks

provided dynamic, natural, mellow sound.

The polypropylene capacitors, selected among various components manufactured through

different technologies and materials, proved to perform excellently, gaining their place in the

crossovers circuit board.

When we tested the resistors attenuation and damping, we realised there were none in the

market which could meet the best quality standards. Every wire resistor, even the ones wound

with anti-inductive technology, generates an unreal inductance which causes an audible shifting

in the audio range. Metaloxide resistors don't have this problem but are less efficient in

dissipating heat because of their mechanical nature.

To have the best sound and HERTZ products typical reliability, we therefore developed a

special, innovative device which uses three resistors in parallel, with an aluminium heat sink able

to provide unbelievable thermal delta.

The device total dissipation is higher than 25 W.
