PRECAUTIONS
Before installing the components, please carefully read all of the instructions contained in this manual. It is advisable to carefully follow the highlighted
instructions. Failure to respect these instructions may cause unintentional harm or damage to the components.
SAFETY CONSIDERATIONS
1. Check your alternator and battery condition to ensure they can handle the increased consumption.
2. Do not install components inside the engine compartment or expose them to water, excessive humidity, dust or dirt.
3. Never run cables outside the vehicle/vessel or install the amplifier next to electronic gearcases.
4. Install the amplifier in the vehicle/vessel sections where temperature is between 0°C (32°F) and 55°C (131°F). Leave at least 5 cm (2 ") of space around
the amplifier. There must be good air circulation where the amplifier is installed. If you cover the heat sink, the amplifier goes into protection mode.
5. Make sure the location you chose for the components does not affect the correct functioning of the vehicle/vessel mechanical and electrical devices. This
amplifier was designed for installation/application in marine vehicles and it is not water-proof. The installation should be performed in a dry compartment
with no direct contact with water.
6. Make sure the power cable does not short circuit during installation and connection.
7. Use extreme caution when cutting or drilling the vehicle/vessel panels, checking there are no electrical wiring or structural elements underneath.
8. Use rubber grommets to protect the wire when running through holes in metal and use proper materials if close to heat-generating devices.
9. Make sure all the cables are properly secured along their entire length. Also, make sure their outer protective jacket is flame resistant and self extinguishing.
Secure the connected cables close to the terminal blocks with wire ties or clamps.
10. Pre-plan the configuration of your new amplifier and the best wiring routes to ease installation.
HOW TO CONNECT THE HMD1
The following graphics represent the main steps for the HMD1 connections. Its universality and versatility offer endless possibilities and configurations.
Specific steps or different procedures may be required in some applications. If you have any questions about configuration or function, please refer to
the Advanced Manual that you can find in the CD inside the gift box or contact your Hertz dealer or Hertz authorized service center for assistance. For its
operation and for any other need, please refer to the following pages of this manual.
1. Before installing the HMD1, turn off the source and all other electronic devices in the audio system to prevent any possible damage.
2. Run a specifically designed power cable with proper diameter (8 AWG, Ø 3.2mm/0.128') from the HMD1 battery.
3. Connect the power supply with the correct polarity. connect (+) terminal to the cable coming from the battery and (-) terminal to the vehicle/vessel chassis.
4. Put an insulated fuseholder maximum 20 cm far from the battery positive terminal; connect one end of the power cable to it after connecting its other
end to the amplifier.
5. TURN ON: the HMD can be turned on through:
- Remote In, by connecting the terminal to the Rem Out of an After Market head unit or from the relaunch wiring of an amplifier from the HMD line.
The logo on the top side of the heatsink lights blue, indicating that the product is on. A flashing of the RED logo every second indicates the activation of
the thermal protection 2 flashes of the RED logo every second indicate an "OVERLOAD" / Fault in the wiring of the speakers, 4 flashes of the RED logo
every second indicate the activation of the "OVERVOLTAGE" protection caused by a battery voltage higher than 17 V, the RED logo turning on indicates an
internal failure of the product, please contact the authorized customer service center.
6. SPK IN: HI LEVEL monophonic analog input. Use the multipoint connector provided to connect to an amplified source or an amplifier from the HMD.
The signal to be applied must have a level between 2 and 20 V RMS. The input sensitivity of the HMD1 is controlled by the "SENSITIVITY" 3-position switch:
2 V - 6,5 V - 20 V.
7. PRE IN: Low level monophonic analog input. Use an RCA connector to connect to an audio source or to an amplifier from the "HMD" line featuring this
connection. The signal to be applied must have a level between 0,6 V; and 6 V RMS. The input sensitivity of the HMD1 is controlled by the "SENSITIVITY"
3-position switch: 0,6 V - 2 V - 6 V.
8. SPEAKER OUT: power terminal + and - of the monophonic output. The available power at the output is
9. FUSE: to replace the fuse, remove it from its holder located near the power supply terminal block and replace it with another fuse of equal value.
10. IINSTALLATION: all components must be firmly fixed to the vehicle structure. Do the same when installing any additional custom structures you may have
built. Make sure that your installation is solid and safe. A component coming loose while driving may cause serious damage to the passengers, as well as
to other vehicles. When the installation is complete, check the system wiring and verify that all connections were performed correctly.
11. A careful reading of the Advanced Manual is essential for a proper use of HMD1.
12. Warranty Certificate: please check out the Hertz website for further information.
SAFE SOUND
USE COMMON SENSE AND PRACTICE SAFE SOUND. PLEASE REMEMBER THAT LONG EXPOSURE TO EXCESSIVELY HIGH SOUND PRESSURE LEVELS MAY
DAMAGE YOUR HEARING. SAFETY MUST BE AT THE FOREFRONT WHILE DRIVING.
Information on electrical and electronic equipment waste (for those European countries which organize the separate collection of waste)
Products which are marked with a wheeled bin with an X through it can not be disposed of together with ordinary domestic waste. These electrical and electronic products must be recycled in proper
facilities, capable of managing the disposal of these products and components. In order to know where and how to deliver these products to the nearest recycling/disposal site please contact your
local municipal office. Recycling and disposing of waste in a proper way contributes to the protection of the environment and to prevent harmful effects on health.
