AMPLIFIER SETTINGS

Signal Input and Output Configurations

The input section of the amplifier consists of a phase switch that sets the output configuration, gain controls, high pass and low pass crossovers controls, Intelli-Q control, and RCA inputs. The input section makes it easy to adapt this amplifier to most system configurations.

Input Gain

These Orion amplifiers have level adjustments to allow for easy integration with any source unit. The input sensitivity is a push button adjustment, with the depressed (in) position giving you a range from 400mV to 8V while in the out position this range is 200mV to 4V. Refer to Testing the System and Adjusting the Sound of the System under Setup and Troubleshooting section of this guide for detailed instructions on setting the gain.

Phase Switches

L 0° - leaves output unaffected. The output signal is in phase with

the input signal.

L 180° - inverts the output. The channel is 180° output of phase.

This configuration is useful for inverting the phase of subwoofers to improve staging in a vehicle.

Internal Crossover Configurations

The crossover section of the Orion HCCA25001, and HCCA50001 amplifiers is continuously variable and extremely flexible. In addition to the variable built-in low-pass filters, the high-pass crossover incorporates the Intelli-Q feature. This circuit is designed to optimize the perfor-

mance of Orion subwoofers in all types of enclosures. When using Orion loudspeakers, minor deviations from the recom-

mended frequency ranges can provide superior results depending on your speaker locations and your vehicle acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide superior sonic results depending on your system’s performance goals. Refer to your loudspeaker owner’s manual for assistance in choosing the proper crossover frequencies for your system.

WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by the manufacturer’s warranty.

Low-Pass Crossover

When the Slope button is in the out position, the low-pass crossover is active with a 2nd order (12dB per octave) slope. When the button is in the depressed (in) position, the low-pass crossover is active with a 4th order (24dB per octave) slope. The low-pass crossover is continuously variable from 20Hz to 300Hz.

High-Pass Crossover

When the On/Off button is the out position, the high-pass crossover is bypassed. When the button is in the depressed (in) position, the high-pass crossover is active with a 2nd order (12dB per octave) slope. The high-pass crossover is continuously variable from 20Hz to 200Hz and is optimized for use as a subsonic filter. Additionally, boost can be added at the high-pass crossover frequency for improved bass output while still protecting the woofer from excessive excursion. The Intelli-Q adjustment allows up to 10 dB of boost at the selected crossover frequency.

WARNING! Exercise caution when setting Intelli-Q. Maximum boost can potentially cause woofer damage due to over-excursion.

Fine Tuning the Crossovers

The low-pass and high-pass crossover sections are each marked at four frequency points for ease of system adjustment. The low-pass crossover section is marked at 20Hz, 50Hz, 150Hz, and 300Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 200Hz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers.

Remote Gain Operation

The remote gain port provides easy remote access to the internal gain structure of the HCCA power amplifier. The RGC2 plugs into the amplifier via the 1/8” mini jack plug. The RGC2 can be installed in the front of the vehicle to control the amplifier gain level. The RGC2 can be used as a bass level control when used on an amplifier dedicated to subwoofers.

Adjusting Intelli-Q

Incorporated in the high-pass crossover, Intelli-Q maximizes the performance of a subwoofer. The high-pass subsonic filter removes

unwanted bass output from the woofer, increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical power handling. Depending on the enclosure, using Intelli-Q can increase the low frequency response by an additional 10dB! The type of enclosure used and the woofer’s excursion capability determine acceptable boost levels. Listed next are recommended boost levels for different enclosure designs.

Infinite Baffle Example High-Pass Set at 30Hz

By removing low frequency signal that the woofer cannot produce, the woofer can play its capable range louder. The first example is an infinite baffle situation. The first graph displays the frequency response of a 12-inch woofer in an infinite baffle application without the high-pass filter, with the filter and with the filter and the Intelli-Q set to +3dB. As you can see, with +3dB of boost and the high pass

filter set to 30Hz, the woofer has more output down to 25Hz and less overall excursion when compared to the non-high-pass response. Maximum physical excursion capability of the woofer is 15mm.

Sealed Example High-Pass Set at 20Hz

This sealed example is the same 12-inch woofer in the recommended sealed enclosure. Up to 6 dB of boost is capable if 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz.

Figure 7 Figura 7 Abbildung 7

Figure 6 Figura 6 Abbildung 6

NOTE: The first graph is the response; the second graph is the driver excursion. These designations apply to the following graphs as well.

Figure 8 Figura 8 Abbildung 8

Sealed Example High-Pass Set at 30Hz

In this example, the frequency has been increased to 30 Hz. Up to 6 dB of boost is capable at this frequency. With +6dB of boost, the woofer has more output down to 23 Hz. The overall usable output is increased.

Vented Example High-Pass Set at 30Hz

Vented enclosures benefit most from the Intelli-Q. Up to 10 dB of boost is capable at the box tuning frequency of 30 Hz. With +10dB of boost, the woofer has more output down to 22 Hz. The excursion below the tuning frequency has been greatly reduced.

battery and the chassis.

NOTE: The addition of a ground wire from the battery to the chassis of the vehicle improves the ability of the battery to supply power to the amplifier. This is recommended because the current delivery of the factory electrical system was designed only to accommodate electronics supplied by the auto manufacturer.

WARNING! The Orion HCCA amplifiers have a single input for power and a single input for ground. Both connections must use 1 AWG wire for proper operation. Failure to do this may damage the amplifier and is not covered under warranty.

Running more than one of the same amplifier (Master/Copy)

NOTE: When expanding your system by adding additional Orion amplifiers in the signal chain use only the same model(s) as the first amplifier in the chain. Refer to Adjusting the Sound of the System (Advanced) under Setup and Troubleshooting section of the manual, this will insure that all amplifiers on the chain are working at the same potential.

The line outputs on Orion amplifiers offer easy, unlimited system expansion. Routing signal from a source unit, pre-amplifier, or equalizer is a matter of connecting RCAs to the RCA inputs of the first Orion amplifier and then the RCA line outputs to the next Orion amplifier’s RCA line inputs in the signal chain. Then the LINE OUT switch on each of the amplifiers is set as follows: The first amplifier in the signal chain will have its LINE OUT switch set to the MASTER position. In effect this first amplifier will set the Crossover, Intelli-Q and have remote gain control for the remainder of the amplifiers in the signal chain. The Crossover on all the Copy amplifiers should be set at the highest frequency at 300Hz, and the Intelli-Q should be set at the lowest frequency at 20Hz this will allow the Master to control the crossover and Intelli-Q setting for all of the copy amplifiers. The remaining amplifiers following in the signal chain will have their LINE OUT switch set to the COPY position. This allows the signal to be input directly, bypassing the subsequent amplifiers gain control. Refer to item #7 under Top Panel Layout of End panel Layout section of this guide for LINE OUT settings explanation.

The following is an example of how to wire multiple amplifiers using one input from the source unit. This can be done with as many amplifiers in the chain as necessary.

ance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis.

Choosing Mounting Locations

The location of your amplifier will depend on several important issues. Due to the low profile size of the Orion amplifiers, there are many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the amplifier from the elements. In addition, mount the amplifier on a stable, flat surface.

NOTE: Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown.

WARNING! Do not mount any amplifier in the engine compartment. Amplifiers are not designed to endure the harsh environment of the exterior elements.

Passenger Compartment

If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1” of clearance around the amplifier for adequate cooling.

Trunk Compartment

Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier with as much clear-

General Precautions and Installation Tips

WARNING! Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle.

Disconnect the vehicle’s ground wire at the battery before making or breaking connections to the audio system’s power supply terminals.

Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier becomes a dangerous projectile in the event of a crash. Never mount the amplifier where it might get wet. Mount the amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or damaged in any fashion.

The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 12”. Use the recommended fuse size or circuit breaker listed in the Power Connections section of this manual.

If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the same size and type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the Power Connections section of this manual for details. Using a higher current fuse may result in damage to the amplifier that is not covered under warranty.

NOTE: Make sure all the equipment in the system is turned off

when making or breaking connections to the input RCAs or speaker terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections.

Power for systems with a single amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor. We strongly recommend the use of an Orion Wired power capacitor with an extra battery in larger stereo systems.

Orion amplifiers generate a certain amount of heat as part of normal operation. Be sure the area around the amplifier is unobstructed to allow adequate air circulation. Remember, beach blankets, last week’s laundry, school books and homework papers located on top of the amplifier do not improve air flow and may become damaged.

You must first remove the top cover (see Removing the Top Cover section) then end caps to mount the amplifier (mounting holes are within). (1) Remove the screws first, (2) lift the end cap straight up to detach from unit and then (3) pull away from the amplifier. Once mounted replace end caps by following this process in reverse.

Step By Step Installation

NOTE: Connect all input, power and speaker connections to amplifier before mounting the amplifier in its final location.

Determine the location for the amplifier. Refer to the 1. Choosing Mounting Locations section of this guide for detailed information.

Decide on the system configuration for your amplifier. For system 2. suggestions, refer to the Speaker Connections section of this guide.

Run all the wires from the amplifier location to the speakers, 3. source unit, and battery. Do not connect the battery at this time. Be sure to run RCAs and power and speaker wires away from factory electrical wires and system as they pose a great potential for induced system noise.

Remove end caps before mounting the amplifier (see figure 4.

15). Top plate must first be removed to remove end caps (see Removing the Top Cover section).

Pre-drill amplifier mounting holes. Be sure to “think before you 5. drill”. Gas tanks, fuel lines, mechanical/electrical systems and/or other obstructions may be hidden beneath mounting location. For best results use a marking pen to mark the mounting holes and pre-drill these holes with a standard 1/8” drill bit.

Mount the amplifier. Make sure the amplifier is mounted on a 6. flat surface. If this is not possible, do not over tighten the screws so that the chassis of the amplifier is twisted or bent.

Turn the vehicle’s key switch to the off position.7. Disconnect the vehicle’s battery ground terminal.8. Connect power wires to the amplifier (ground first, then 12 V(+) 9.

and REM). Power wire must be fused near the battery. Be sure to remove the fuse from the fuse holder at this time.

Connect the RCA and speaker wires to the amplifier. Check the 10. quality of your speakers and signal connections. This will determine the ultimate performance of your Orion amplifier. Refer to the Signal Input and Output Configurations and Speaker Connections sections of this guide for correct wiring instructions.

Reconnect the ground terminal to the battery after power, 11. speaker, and RCA connections are completed.

Set crossovers. Refer to the 12. Internal Crossover Configuration sec- tion of this manual for detailed instructions.

Set gain control to a low level before turning on the amplifier. 13. Adjust gain control as needed after the system is playing. (see adjusting the sound of the system)

Once satisfied that all connections and settings are correct, install 14. the fuse located near the vehicle’s battery and proceed to the Testing the System section of this manual.

After all connections and adjustments are made, install end caps 15. and cover if they are to be used.

WARNING! Never exceed the recommended fuse size of this amplifier. Failure to do so will result in the voiding of your warranty and possible damage to the amplifier.

SETUP AND TROUBLESHOOTING

Testing the System

After you have completed the installation, you need to test the system. This will help ensure years of trouble-free operation. Please refer to the listed following steps when testing the sound of your Orion system.

Check all the wiring connections to be sure they are correct and 1. secure.

Turn the signal source volume control all the way down. Set any 2. tone controls to their flat or defeated positions. This includes the loudness control.

Turn the level controls of the amplifier to their minimum posi-3. tions.

Turn the source unit on. Check to see if the power LED located 4. on the connection side of the amplifier is on. If not, please refer to the Power Connections and the Troubleshooting Tips sections of this manual for instructions.

If using an aftermarket source unit, turn the level controls of the 5. amplifier about one quarter of a turn. Slowly increase the volume level of the source unit to so that you can hear the output of the system. If no sound is heard or if the output is distorted, turn the system off immediately. Refer to the Power Connections and the Troubleshooting Tips sections of this manual to solve your installation problems.

Check to make sure the output for each channel is correct. If the 6. active crossovers are used, check to make sure that each output is

correct from the amplifier. When using active crossovers on midrange and tweeters, do not use crossover frequencies lower than recommended. If the system is not configured properly, refer to the Internal Crossover Configuration section of this manual and take corrective action.

If the output is clear and undistorted, continue to the 7. Adjusting the Sound of the System section of this manual.

Adjusting the Sound of the System (Basic)

Once you have checked the system’s operation, adjust the sound of the system. Adjusting the sound of the system is accomplished by setting the level controls and adjusting the internal crossovers.

Turn the signal source volume control all the way down. Set any 1. tone controls to their flat or defeated positions. This includes the loudness control.

Turn the level controls of the amplifier to their minimum posi-2. tions.

Choose music with high dynamic content that you like, with which 3. you are familiar, and will be used most often in the system.

Turn the source unit’s volume control up to its highest undis-4. torted output level. If you lack test equipment, this point occurs between 3/4 to full volume depending on the quality of your source unit. Listen for any audible distortion. If any distortion is audible, reduce the volume of the source unit until you have an undistorted output. Leave the volume control at this position during your system tuning.

While listening to your chosen dynamic music, turn up the level 5. control corresponding to the midrange output until you hear

slight distortion and turn the level control back slightly for an undistorted output. Depending on your system, the midrange and tweeter output may be on the same output channels.

Turn up the level control corresponding to the tweeter output 6. until you hear slight distortion and turn back the level control slightly for an undistorted output. Depending on your system the midrange and tweeter output may be on the same output channels.

Fine-tune the output level between midrange and tweeters. 7. Refer to the Internal Crossover Configuration section of this manual for detailed instructions.

Repeat Steps 5-7 for the rear speakers. If you do not have rear 8. speakers continue to Step 10.

Set levels between the front and rear midrange and tweeters for 9. optimum front/rear balance.

Turn up the level control corresponding to the woofer output 10. until you hear slight distortion and turn back the level control slightly for an undistorted output.

Fine-tune the output level between satellite speakers and the 11. woofers. Refer to the Internal Crossover Configuration section of this manual for detailed instructions. If using an RGC2, adjust the level to the output of the woofer to match the sonic requirements of the system.

Enjoy your awesome Orion sound system.12.

Adjusting the Sound of the System (Advanced)

This method requires using a digital multimeter (DMM) and is more accurate than adjusting by ear. Find the optimum AC voltage output of your amplifier by using Ohm’s law. For example: if you have a 200 watt (rms) mono amplifier that you are going to run at 2 ohms. Multiply the power by the resistance which equals 400, the square root of 400 is 20. According to the calculation, the amplifier needs to read 20 volts AC for optimum power output.

P x R

E = E = AC Voltage that will be measured across speaker outputs. P =

Power in Watts, R = Total Resistance of a speaker(s) hooked to one channel.

The following steps detail the process.

Using Ohm’s law calculate the amplifiers target voltage output 1. (as in the afore shown example).

Obtain a test tone CD with 50Hz tone for Subwoofer amplifiers. 2. Make sure the sin-waves has a 0db reference level at 50Hz.

Disconnect all the speakers from the system.3. Turn off all source unit processing, Loudness, EQ’s, Intelli-Q and 4.

Amplifier Visual Troubleshooting

Your new Orion HCCA amplifier has three indicator lights (LED’s) on the top cover of the amplifier as seen in the next figure. These lights are very useful in troubleshooting possible amplifier problems and issues.

Power LED: This LED lights up green when the amplifier is turned on. This represents normal operation if the Protection/ESP Status LED is on solid, and the Thermal LED is off.

Protection /ESP Status Indicator LED: This LED lights up blue if the amplifier goes into protection. It also will flash when the amplifier is powering up, approximately 4-5 flashes until the turn-on delay has expired (actual number of flashes depends on the length of time selected via the bitwriter). Below is a description of reasons the amplifier could engage the protection circuit. The protection indications will self reset once the condition has been fixed. Advanced troubleshooting can be performed using the ESP Status LED.

Short:s Speaker wires pinched or shorted together or to ground (frame of vehicle). ESP Status LED will also flash two short flashes, followed by a long pause( approximately 8-10 seconds). Overcurrent:s Check for possible speaker issue(s) or speaker wiring pinched in a door or other metal. Make sure speaker(s) load is not below minimum 1Ω load. The ESP Status LED will also flash 2 short pulses, followed by a long pause. DC Offset:s This can happen if the installation inadvertently connects the power wire to the speaker input(s). This can also happen if the amplifier has an internal problem. The amplifier will flash 4 short pulses, followed by a long pause, then repeat. Undervoltage:s Vehicle charging system is not supplying enough voltage to the amplifier. This can also occur if you use too small

a gauge wire or the terminals connecting the amplifier power to the electrical system are dirty or corroded. The ESP status LED also will give one short flash followed by a long pause for undervoltage. This cycle will repeat. Overvoltage:s Vehicle charging system is supplying too much voltage or over the amplifiers rated DC input. Usually this occurs when there is a problem with the electrical system. Turn off the headunit when jump-starting the car. The ESP Status LED will also flash with one long flash followed by a long pause (approximately 8-10 seconds). Thermal:s If the amplifier heat sink temperature is too high to continue safe operation, it will also enter protection mode. The ESP/Protection status LED will give 3 short flashes followed by a long pause. This cycle will then repeat.

Thermal LED: This LED lights up red if the amplifier overheats. An amplifier enters thermal protection due to conditions that might otherwise result in damage to the amplifier. The thermal protection mode is also indicated on the Protection/ESP Status indicator by a 3 short flash sequence that repeats every 8-10 seconds. Below is a description of reasons the amplifier could engage the Thermal Circuit.

they produce energy and care and consideration should be taken into account when installing any amplifier. The temperature inside the car where the amplifier is mounted is s extremely hot. This can occur in extreme climatic conditions. It is not uncommon for temperatures inside a parked car to reach in excess of 140°F (60°C). If airflow is restricted to the mounting area, the main car cabin may cool down before the rest of the car has dropped appreciably. Also, if the amplifier is near the thermal protection temperature point, turning it on and off via the remote line can result in it entering thermal protection.

The amplifier can also overheat if it is not receiving proper s ventilation, when mounting a amplifier make sure it has room for air to circulate and keep it cool. Amplifiers will get hot because

NOTE: Please note that the top cover plate is designed to be reversible. The LED colors will therefore appear to reverse their order relative to the diagram labeling if the cover is reversed when reattached, for example; the green LED (power) closest to the Orion logo in the diagram will be the furthest from the logo with the cover reversed.

APPENDIX—PROGRAMMABLE FEATURES

The following listing are ESP®-2 features that can be programmed or accessed by your installer to customize or troubleshoot your system. Factory default settings are shown in bold.

NOTE: The Bitwriter® must have software version 2.7 or above to access the amplifier features menu.

NOTE: A setting marked “Reserved” is for future development. Some settings are read-only, i.e. they cannot be changed, only viewed. If changed, the bitwriter will fail verification of the parameters upon write and indicate an error.

Turn On Delay - 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 seconds. Delays the amplifier turn-on when the head or source unit is turned on. This eliminates any annoying pops or noise during power up from the head or source unit from feeding through to the speakers.

Input Gain Range (Volts) - The position of the gain switch determines the gain range available. If the gain switch is in the high mode, the ranges are Default (0.2 - 4V), 0.2-1V, 1-1.5V,1.5 - 3.5V, 3.5-4V. If the gain switch is in the low mode, the ranges are Default (0.4 - 8V), 0.4 2V, 2 -3V, 3V - 7V, 7-8V.

NOTE: If the Input Gain Adjustment is set to Lock (see below), the Input Gain Range adjustment will not be altered until the Input Gain Adjustment is set to Unlock.

Input Gain Adjustment - Unlock, Lock. When set to “Lock”, the input gain adjustment is disabled. This can be set to lock after the amplifier has been installed and set up to prevent accidental or unwarranted adjustment.

NOTE: Use caution when adjusting or unlocking gain as restricting the range or unlocking the range can result in sudden increases in gain. We recommend turning down the source to avoid damage to speakers or your hearing.

Event 1 through 7 - Stores up to seven recent events that have occurred to aid in diagnostic troubleshooting. The events that are retained are: Undervoltage, Overvoltage, Reserved, No Fault, Thermal, Overcurrent. These events are read-only, the amplifier will not allow them to change, even if they are changed on the bitwriter, they cannot be written to the amplifier by the installer. Event 1 is the most recent event, then Event 2, and so on. If event memory is full (Event 7 has a stored diagnostic message), then if another event occurs the 7th event will be pushed out of memory.

NOTE: While the Bitwriter

can be used to read the amplifier during

an event, the priority of the amplifier is given to continually checking its health. Attempts to Write to the amplifier during and immediately following an event may result in communication errors.

Ordinarily, the amplifier should clear any faults when the condition that causes them clears. Substantial changes to the amplifier parameters via the bitwriter may result in the audio being interrupted momentarily. Also, the amplifier is designed to fade up from protection events and when turned on.

NOTE: The amplifier can be reset by removing power to the main battery terminals and keeping the remote line off for at least 30 seconds.

The major and minor revision levels of the ESP2 software should be referenced should it be necessary to contact Directed Electronics or Orion.

RÉGLAGES DE L’AMPLIFICATEUR

Configurations d’entrée et de sortie du signal

La section d’entrée de l’amplificateur comprend un commutateur de phase qui définit la configuration de sortie, des réglages du gain, des filtres passe-haut et passe-bas et de la fonction Intelli-Q, et des entrées RCA. La section d’entrée facilite l’adaptation de cet amplificateur à la plupart des configurations de systèmes.

Gain d’entrée

Ces amplificateurs Orion comportent des réglages de niveaux facilitant l’intégration avec tout appareil source. La sensibilité d’entrée se règle par un bouton-poussoir, la position enfoncée correspondant à une gamme de 400 mV à 8 V, et la position sortie à une gamme de 200 mV à 4 V. Les sections Essai du système et Réglage du

Commutateurs de phase

0°: aucun effet sur la sortie. Le signal de sortie est en phase avec s le signal d’entrée. 180°: inversion de la sortie. Le canal est déphasé de 180°. Cette s configuration est utile pour l’inversion de phase des haut-parleurs extrêmes graves, afin d’améliorer la répartition acoustique dans un véhicule.

Configuration des filtres internes

La section de filtrage des amplificateurs Orion HCCA25001 et HCCA50001 permet un réglage continu et extrêmement flexible.

Outre les filtres passe-bas variables intégrés, le filtre passe-haut comporte la fonction Intelli-Q. Ce circuit a été conçu pour optimiser les performances des haut-parleurs extrêmes graves Orion dans tous les types de caissons de graves.

Lorsque des haut-parleurs Orion sont utilisés, de petits écarts par rapport aux plages de fréquence recommandées peuvent donner de meilleurs résultats, selon les emplacements des haut-parleurs et l’acoustique du véhicule. Le réglage des fréquences de filtres à des valeurs supérieures à celles recommandées n’entraîne pas de dommages et peut permettre des résultats sonores supérieurs, selon les objectifs de performances du système. Consulter le manuel d’utilisation du haut-parleur pour le choix des bonnes fréquences des filtres du système.

AVERTISSEMENT! NE PAS régler les fréquences des filtres à des valeurs inférieures aux plages de fonctionnement recommandées des hautparleurs. Cela risque de provoquer des dommages du haut-parleur non couverts par la garantie du fabricant.

Filtre passe-bas

En position sortie du bouton SLOPE (pente), le filtre passe-bas est actif avec une pente du 2e ordre (12 dB par octave). Lorsque le bouton est enfoncé, le filtre passe-bas est actif avec une pente du 4e ordre (24 dB par octave). Le filtre passe-bas est variable de façon continue de 20 à 300 Hz.

Filtre passe-haut

Lorsque le bouton ON/OFF est en position sortie, le filtre passe-haut est désactivé. Lorsque le bouton est enfoncé, le filtre passe-haut est

actif avec une pente du 2e ordre (12 dB par octave). Le filtre passehaut, variable de façon continue de 20 à 200 Hz, est optimisé pour une utilisation comme filtre subsonique. En outre, un renforcement peut être ajouté au niveau du filtre passe-haut pour une amélioration des graves en sortie tout en protégeant le haut-parleur de graves contre une course excessive. Le réglage Intelli-Q permet un maximum de 10 dB de renforcement à la fréquence de coupure sélectionnée.

AVERTISSEMENT ! Régler la fonction Intelli-Q avec prudence. Le renforcement maximal risque d’endommager les haut-parleurs de graves à cause d’une course excessive.

Réglage fin des filtres

Chacune des sections de filtres passe-bas et passe-haut est repérée suivant quatre points de fréquence pour faciliter le réglage du système. La section de filtre passe-bas est repérée à 20 Hz, 50 Hz, 150 Hz et 300 Hz. La section de filtre passe-haut est repérée à 20 Hz, 33 Hz, 90 Hz et 200 Hz. Des points de coupure particuliers peuvent être choisis en fonction de la largeur de bande opérationnelle recommandée des haut-parleurs.

Utilisation de la télécommande du gain

Le port de télécommande du gain offre un accès distant facile à la structure de gain interne de l’amplificateur de puissance HCCA. La télécommande RGC2 se branche dans l’amplificateur par une minifiche de 3 mm. La télécommande RGC2 peut être installée à l’avant du véhicule pour commander le niveau de gain de l’amplificateur. Utilisée sur un amplificateur dédié aux haut-parleurs extrêmes graves, elle peut servir à régler le niveau de graves.
