1 INTRODUCTION GENERAL RECOMMENDATIONS Safety precautions • The vehicle electric system must have 12VDC voltage with negative to ground. Make sure your car has it in order to avoid any damages to your amplifier and to the car itself. • Suitably fix the amplifier paying utmost attention if you install it into the driver’s compartment. Use extra fixing systems if you install it inside the bonnet. If the amplifier detaches itself while you are driving, it can severely damage people and other vehicles.
2 INTRODUCTION DESCRIPTION 1 • PROJECT PURPOSE Audison has always pursued the best audio reproduction in all of its products. The creation of the HR100 in 1991 occurred simultaneously with the achievement of a technological goal. On one hand it appeared to use all the knowledge attained to this date, yet on the other hand it set a landmark for years to come.
2 INTRODUCTION DESCRIPTION The final power stage uses an innovative topology, which aims at increasing Class “A” polarization as much as possible. The whole input circuit is balanced up to the final stage “Front End”, while the amplifier’s configuration is “Dual Mono”. In order to avoid electro-magnetic interferences, no high current is passed on the main board, with the exception of power supply terminals; this solution was achieved through the use of a second board that is located under the main board.
2 INTRODUCTION DESCRIPTION JFET differential input stage (available in PRE ON configuration). Selectable two level input gain structure adjusted (available in PRE ON configuration). Balanced output buffer for control unit (available in PRE ON configuration). Thermally stabilized (available in PRE ON configuration). Control Unit: Allows the amplifier to be properly configured and adjusted. - Sensitivity. Adjusted using the IN SET switch and ADJUST control.
2 INTRODUCTION DESCRIPTION value on every output device is possible, keeping stable the total current absorbed by the amplifier when in idling status. All this results in the increase of the output stage to class A value. This value is the typical car audio amplifiers’ weak point. Due to installation needs, they always require several output devices in parallel in order to work on very low loads and in the meantime to have low consumption since the car battery supplies them.
2 DESCRIPTION INTRODUCTION Indications shown on the Status Monitor are: POWER ON: The amplifier turn on status. HI POWER: When on Dual Power is in Hi Power mode, if turned off it means it is in Hi Current mode. In the case of wrong fuse positioning, master protection activates. FAN ON: Cooling system is active. TEMP GOOD: If solidly illuminated, it indicates the best operating temperature for maximum listening pleasure; if it blinks, please wait.
2 DESCRIPTION INTRODUCTION Drivers were attached to it, while the preamplifier is connected to it through copper bars. The fan is managed by the ASC unit, permitting it to quickly reach the optimal temperature and stabilize it. The air pulled in by the fan is discharged between the main board and aluminium bottom plate, then it goes out through the input and power terminal sides of the amplifier.

1 OWNER’S MANUAL INPUTS - OUTPUTS PANEL 1 • LEFT SPEAKER Amplifier left channel (Left) power ouput. Connect speakers cables to this output according to indicated polarity. If you use the amplifier in MONO configuration, take positive output from + Left terminal block. 2 • LEFT PRE OUT (ABS connector) Left channel (Left) preamplified output to send to another amplifier. The signal in this output is the LEFT PRE IN input one. 3 • LEFT PRE IN (ABS connector) Amplifier left channel (Left) input.
2 OWNER’S MANUAL POWER SUPPLY - SWITCHING ON PANEL 1 • - POWER (GROUND) Terminal block for the amplifier power supply negative pole connection. Connect the battery negative cable or the one connected to the vehicle chassis to it. Holes have 9.5 mm (.37 inches) diameter and accept cables up to 2 A.W.G. For better current transfer, power supply cables have to be as big as possible. 2 • - CAP (18V min) Terminal block for connecting the negative terminal of a possible external capacitor.
3 OWNER’S MANUAL CONTROLS PANEL 1 • OUT MODE It permits to configure the amplifier in STEREO or MONO. If you put Out Mode control on STEREO, PRE IN LEFT and RIGHT inputs signals are separately amplified and they are in SPEAKER LEFT and RIGHT outputs. If you put Out Mode control on MONO, you shift phase in the Right channel and you can thus bridge the device.
4 OWNER’S MANUAL CONTROL FUNCTIONS AND PROTECTION ASC – Amplifier Status Controller Unit ASC handles all the amplifier functions, except sound. It has a microprocessor and through its Status Display, it permits to visualise working functions and possible anomalies both of the amplifier and of the whole system. It drives VUmeter for output power visualisation, it controls protection and adjusts the temperature of various parts by controlling fans activation and speed. POWER ON (green) The amplifier is on.
5 OWNER’S MANUAL GLASS PANEL REMOVAL a. Unscrew the 6 screws which fix the glass panel b. Before closing the product, make sure there are no objects inside. Put the glass panel back. Fasten the 6 closing screws. Caution!: Panel is made of very sturdy, tempered glass but we suggest you avoid any bumps against hard objects. Handle with care. In case it breaks, it will generate countless little pieces which are not harmful for your hands. Contact Audison service centres in order to replace it.
