AMPLIFIER SETTINGS

Signal Input and Output Configurations

Depending on your model, the input section of the amplifier consists of gain controls, high

pass and low pass crossovers controls, Intelli-Q control, Intelli-Bass control and RCA inputs

and outputs. The input section makes it easy to adapt this amplifier to most system config-

urations.

Input Gain

These Orion amplifiers have level adjustments to allow for easy integration with any source

unit. The input sensitivity can be adjusted from 150mV to 5V. Refer to Testing the System

and Adjusting the Sound of the System sections of this guide for detailed instructions on

setting the gain.

Line Output Configurations

The line outputs on Orion amplifiers offer easy system expansion. Routing signal from the

RCA line outputs to the next Orion amplifier’s RCA line inputs in the signal chain.

Internal Crossover Configurations

The crossover section of the Orion amplifier 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 performance of Orion subwoofers

in all types of enclosures.

When using Orion loudspeakers, minor deviations from the recommended 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 man-

ufacturer's warranty.

Crossover Switch

Controls the type of filter for the onboard active crossover. The HP-4800 has two switches,

the upper switch is for channels 1/2, the lower switch is for channels 3/4.

Full position does not attenuate any frequencies and is for full range speaker systems.

High attenuates low frequencies and is used for mid-range speakers and tweeters.

Low attenuates high frequencies and is used for subwoofer speakers.

Intelli-Q

Intelli-Q is incorporated in the HP-2800, and only on the rear channels of the HP-4800.

Additionally, boost can be added by means of the Intelli-Q adjustment at the high-pass

crossover frequency for improved bass output while still protecting the woofer from exces-

sive 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.

Adjusting Intelli-Q

Incorporated in the high-pass crossover, Intelli-Q maximizes the performance of a sub-

woofer. 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 frequen-

cy response by an additional 10dB! The type of enclosure used and the woofer's excursion

capability determine acceptable boost levels. Listed below are recommended boost levels

for different enclosure designs.

Adjusting Intelli-Bass

Intelli-Bass on the rear channels maximizes the performance of a subwoofer and allows for

continuous adjustment of low frequency boost on the rear channels. Intelli-Bass can be

adjusted from 0dB to 12dB of boost centered at 45Hz. Initially the Q is very low (wide). As

Intelli-Bass is added, the Q rises (narrows). This allows the amplifier to overcome acoustic

deficiencies in your vehicle. The type of enclosure used, the sub-woofer's excursion capabil-

ity, personal preference, and attitude determine acceptable boost levels.

WARNING! Exercise caution when setting Intelli-Bass. Maximum boost can potentially

cause woofer damage due to overexcursion.

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 left 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.

NOTE: The left graph is the response; the right graph is the driver excursion. These des-

ignations apply to the following graphs as well.

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 out-

put down to 15 Hz.

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.

Remote Bass Operation (optional)

The remote bass port provides easy remote access to the internal gain structure of the HP

power amplifier. The optional HP-RB1 plugs into the amplifier via the 1/8" mini jack plug.

The HP-RB1 can be installed in the front of the vehicle near the driver’s position to control

the amplifier bass level.

AMPLIFIER INSTALLATION

Choosing Mounting Locations

The location of your amplifier will depend on several important issues. Due to the low pro-

file 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 min-

imum 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 clearance as possible. This type of mounting will yield the best cool-

ing due to the convection effect of the amplifier chassis.

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, ide-

ally within 18". 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 cur-

rent 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 break-

ing 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 sys-

tems. Systems with multiple amplifiers may require a higher capacity battery, alternator or

the use of a storage capacitor. We strongly recommend the use of a Directed Audio

Essentials 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.

Tools of the Trade

Listed below are the majority of the tools required to perform an installation. Having the

proper tools will make the installation that much easier. Some of these tools are necessities;

some will just make the job easier.

Step 2

Step 3

Determine the location for the amplifier. Refer to the Choosing Mounting

Locations section of this guide for detailed information.

Decide on the system configuration for your amplifier. For system sugges-

tions, refer to the Speaker Connections section of this guide.

Run all the wires from the amplifier location to the speakers, 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.

Step 6

Step 7

Turn the vehicle's key switch to the off position.

Disconnect the vehicle's battery ground terminal.

Step 8

Step 9

Connect power wires to the amplifier (ground first, then 12 V(+) and REM).

Do not connect the battery at this time.

Connect the RCA and speaker wires to the amplifier. Check the quality of

your speakers and signal connections. This will determine the ultimate per-

formance of your Orion amplifier. Refer to the Signal Input and Output Level

Controls and Speaker Connections sections of this guide for correct wiring

instructions.

Step 10 Reconnect the ground terminal to the battery after power, speaker, and RCA

connections are completed.

Step 11 Set crossovers. Refer to the Internal Crossover Configuration section of this

manual for detailed instructions.

Step 12 Pre-drill amplifier mounting holes. Be sure to "think before you drill". Gas

tanks, fuel lines, and other obstructions have a nasty way of hiding them-

selves. For best results use a marking pen to mark the mounting holes and

pre-drill these holes with a standard 1/8" drill bit.

Step 13 Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If

this is not possible, do not over tighten the screws so that the chassis of the

amplifier is twisted or bent.

Step 14 install the fuse located near the vehicle's battery and proceed to the Testing

the System section of this manual.

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.

SET UP 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 steps below when testing the

sound of your Orion system.

Step 1

Step 2

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

Turn the signal source volume control all the way down. Set any tone con-

trols to their flat or defeated positions. This includes the loudness control.

Step 3

Step 4

Turn the level controls of the amplifier to their minimum positions.

Turn the source unit on. Check to see if the power LED located on the con-

nection side of the amplifier is on. If not, please refer to the Power

Connections and the Troubleshooting Tips sections of this manual for instruc-

tions.

Step 5

Step 6

If using an aftermarket source unit, turn the level controls of the 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 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 con-

figured properly, refer to the Internal Crossover Configuration section of this

manual and take corrective action.

Step 7

If the output is clear and undistorted, continue to the Adjusting the Sound

of the System section of this manual.

Adjusting the Sound of the System

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.

Step 1

Turn the signal source volume control all the way down. Set any tone con-

trols to their flat or defeated positions. This includes the loudness control.

Step 2

Step 3

Turn the level controls of the amplifier to their minimum positions.

Choose music with high dynamic content that you like, with which you are

familiar, and will be used most often in the system.

Step 4

Step 5

Turn the source unit's volume control up to its highest undistorted 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 distor-

tion. 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 control cor-

responding 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 chan-

nels.

Step 6

Step 7

Turn up the level control corresponding to the tweeter output 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. Refer to the

Internal Crossover Configuration section of this manual for detailed instruc-

tions.

Step 8

Step 9

Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers con-

tinue to Step 10.

Set levels between the front and rear midrange and tweeters for optimum

front/rear balance.

Step 10 Turn up the level control corresponding to the woofer output until you hear

slight distortion and turn back the level control slightly for an undistorted

output.

Step 11 Fine-tune the output level between satellite speakers and the woofers. Refer

to the Internal Crossover Configuration section of this manual for detailed

instructions.

Step 12 Enjoy your awesome Orion sound system.

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 2.3 or above to access the amplifier fea-

tures menu.

NOTE: A setting marked “Reserved” is for future development.

Turn On Delay - 1.5, 2, 2.5, 3, 3.5, 4 seconds (approximate time delays). Delays the amplifi-

er 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 amplifi-

er.

Service Code Display - OFF, Flash Code on LED, Reserved, Clear Last Fault.

When set to “Off” the service code display will not be displayed on top of the

amplifier (see Top Light Options feature below) and the amplifier operates nor-

mally.

When set to “Flash Code on LED”, the LED on top of the amplifier will be enabled

to flash the diagnostic code (see table below).

The “Clear Last Fault” setting is used by your installer to clear the last fault event

detected by the amplifier.

NOTE: When the Clear Last Fault setting is used, execute a “read” cycle from the

Bitwriter^®prior to attempting further writes. This resynchronizes the Bitwriter .

Input Gain Range (Volts) - Default, 0.15–0.50 V, 0.50–1.00 V, 1.00–3.00 V, 3.00–5.00 V. This

feature allows the input gain range to be limited. This feature is useful to prevent the

amplifier from being overdriven. The “Default” setting turns the Input Gain Range feature

off, the input gain adjustment is settable over the full range of the control.

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 unlock-

ing the range can result in sudden increases in gain.

The Valet Monitoring and Anti Theft options (below) require the ESP2 alarm to be

“learned” into the amplifier. Prior to setting the valet or anti theft to Enable or On, execute

the TXID routine. The ESP2 alarm must be the one installed in the vehicle.

Valet Monitoring - Disable, Enable. Used in conjunction with an ESP -2 security system to

prevent operation of the amplifier when the security system is in Valet mode. When Valet

mode is Enabled, and the valet code is received from the alarm system, the amplifier will

not power up the next time it goes through a remote line On cycle (using the head unit or

other device that turns the amplifier on via the remote turn on line).

Anti Theft - Off, Reserved, On. When set to “On”, and when the ESP -2 security system is

armed, the amplifier will not operate until the security system is disarmed (the remotes used

by the security system must be learned by the amplifier—see “Learn TX IDs” below). If the

security system is armed and then the amplifier is disconnected from 12V DC, the amplifier

will be locked out from operation. You can reset the amplifier by disarming the security sys-

tem (it must be one of the transmitter learned by the system), then cycling the remote

power on/off.

Top Light Options - Light Off W/Service Code, Light On W/Service Code, Light Off W/O

Service Code, Light On W/O Service Code. This feature allows the toplight to duplicate the

function of the ESP status indicator. This is set by the W/Service Code. The toplight may also

be turned off if desired (Light On/Light Off) independent of the Service Code (see table

below).

1. Light Off W/Service Code

2. Light On W/Service Code

Top light is off, but service codes will be shown.

Top light is on, and service codes will be shown.

3. Light Off W/O Service Code Top light is off, but service codes will not be shown.

4. Light On W/O Service Code Top light is on, but service codes will not be shown.

Learn TX IDs - Off, On. When On learns the amplifier learns the remotes (press arm and then

disarm on just one of the remotes) used by a Directed Electronics ESP^®-2 security system. If

any remotes are added or replaced in the system your vehicle must be returned to the deal-

er to have the amplifier learn the new/replaced remotes. The installer uses the following

procedure to learn the security system’s remotes:

1. Unplug the amplifier ESP -2 port from the security system.

2. Connect the Bitwriter to the amplifier ESP -2 port using the cable that came with

the Bitwriter .

3. Turn on the Bitwriter and read the file from the amplifier.

4. Scroll down to Learn TX IDs and select the On setting.

5. Unplug the Bitwriter and reconnect the ESP -2 cable from the security system.

6. Arm the security system (the amplifier ESP LED will flash), then disarm the secu-

rity system. The remotes used with the security system are now learned into the

amplifier. After a short time frame (approximately 20-seconds) the Learn TX IDs

feature will automatically revert back to the default Off setting.

NOTE: The next three features are read only. The amplifier will not permit them to be

changed. If a change is attempted, an “Unable to Verify” error message will appear on the

Bitwriter . If this occurs, simply wait 10-20 seconds, and press Read to restore the system

state to the bitwriter.

Event 1 through 7 - Stores up to seven recent events that have occurred to aid in diagnos-

tic troubleshooting. The events that are retained are: Undervoltage, Overvoltage, Reserved,

No Fault, Thermal, Overcurrent. These events are read-only, they and should not be be writ-

ten 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 prior-

ity 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.

The Major and Minor Rev levels of the ESP2 software should be referenced should it be nec-

essary to contact Directed Electronics or Orion.

Major Rev - Major revision level of the ESP2 software.

Minor Rev - Minor revision level of the ESP2 software.
