1 TETOLON ® DOME
Tetolon ® Fiber dome features a hemispheric-hyperbolic
profile for maximum rigidity and linear frequency
response beyond the audible range.
2 REN ® NEODYMIUM MAGNET
In every component, the motor assembly is centred
upon a REN ® Neodymium ring, capable of operating in
high heat conditions. ML 280 tweeter is equipped with
a double REN ® Neodymium magnet. The use of a REN ®
Neodymium magnet generates extraordinary energy,
for extremely high performance.
3 ALUMINIUM VOICE COIL & COPPER RING
The central pole piece is covered with a pure copper
sleeve. This combined with its CCAW double layer
voice coil wound on a Kapton ® former provides a linear
impedance, ensuring maximum power handling and
frequency extension, even when listened to off axis.
4 RENEWED CROSSOVER
The highest quality components, the Rubber Touch
case, a passive cooling system and a three position
level control: these features make this crossover
unique.
5 ALUMINIUM MAIN STRUCTURE
The use of aluminium permits a perfect control, contri-
buting to the reduction of unwanted resonances and
residual vibrations.
The main structure and the rear acoustic chamber of
the tweeter are CNC machined from a solid aluminium
block. The basket is also made from anti-resonant
aluminium alloy.

MAXIMUM POWER,
MAXIMUM QUALITY,
MINIMUM SIZE
Hertz Digital Power project delivers high power levels while maintaining high
efficiency, in a compact footprint chassis size required in today’s modern
installations. It has inherited all the technologies which made HP successful,
with further advanced performance. More specifically, the D-Class technology
has evolved into a Full Range design for offering stunning musical performance
also with elevated power output.

1 MONITORING LEDs
4 LEDs monitor amplifier status and
communicate with the user in real time.
This system, while allowing the amplifier
to operate, also identifies installation
faults and leads to eliminate them.
3 OPTIMIZED HEATSINK
The heatsink boasts extremely efficient
thermal conductivity, combined with
exclusive cosmetics: scratch-resistant
finish, end caps shaped for easy
handling, control panel accessible from
the top as well as a featured back lit
Hertz logo which can also be rotated.

2 HDP ELECTRONICS
Power supply stage featuring toroidal
transformers with multi-layered windings,
powerful TO220 (for HDP 1) and T220-
5pin with dual inside device (for HDP 4
and HDP 5) Mosfets.
4 HDP IN & ART TM
HDP IN system provides to interface
with any OEM (through the Speaker In)
and aftermarket (through the RCA In)
sources. Using Speaker In inputs, the
ART TM (Automatic Remote Turn On-Off)
function is available; the user can also
switch it off.

1 DIE-CAST AND REFINED HEATSINK
Equipped with an optimized die-cast
heatsink for enhanced thermal performance,
HE amplifiers feature vertical
fins besides the horizontal fins, used in
the traditional extruded heatsink.

2 HE STATUS LOGO
This technology allows the user to visually monitor the
status of the amplifier in real time. The logo lights up of
a blue colour when the amplifier is working correctly,
changing into an orange when it enters into protection
status.
3 HE IN
To interface the HE line with both OEM (Speaker In)
and aftermarket (RCA In). HE IN provides noise-free
installation in any type of system design.
When HE IN is used, ART, Automatic Remote Turn-
On/Off function, automatically turns on and off the amplifier
when the OEM radio turns on and off.
4 HE ELECTRONICS
Underneath the heatsink, multiple winding transformers,
high current 105° C Electrolytic capacitors and low RDS-ON
mosfets are employed. HE 2 and HE 4 are equipped with
SANKEN TO3P output transistors, while HE 1D features a
Class D output stage based on solid TO247 power mosfets,
also employed in the Synchro D-Class circuit.
