XXV EDITION HIGH PERFORMANCE AMPLIFIERS

INDEX PAGE

As Hifonics celebrates its 25th anniversary of producing the finest high end car audio products available we would like to thank

you for your continued support.

The GEN XXV Series range of products have been designed to a very high level of performance, with features unavailable in any

other product.

All of the amplifiers have variable crossovers built in, with added touches such as Subsonic Filter, Parametric Bass Equalization,

Phase Shift, Balanced Line Input and a Bass Remote Control Module that allows bass control from reach of the drivers seat.

To insure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker leads, low

impedance, dangerous high temperatures, DC shorts and will shut down the amp to help prevent serious damage. A new feature

for this series is the Clipping LED indicator. This indicator is located on the amplifier end panel and Bass Remote Control Module.

This LED alerts the user when the amp reaches soft clipping and allows the user to correct the settings prior to reaching hard

clipping and shutting the amp down. To ensure incredible durability, all XXV D-Class amplifiers are now 18 Volt stable, except for

the XXV-Colossus which is 16 Volt stable.

The input level control allows you to match the amplifier input sensitivity to the output level of the RADIO/CD source from 0.2 Volts to 9

volts when using unbalanced (RCA) and 0.2 volts to 18 volts with the balanced input.

PHASE SHIFT:

The Phase Shift is fully adjustable from 0 to 180 degrees.

SYSTEM DIAGNOSTICS:

The amplifier has built-in monitoring devices and protection circuits that monitor all vital functions of the amplifier.

The diagnostics light do not come on to indicate there is a failure, they come on when they detect an improper operation.

THERMAL:

The amp has an internal temperature sensor that will automatically shut off the amp if it reaches dangerous temperature levels and

the LED will be Amber in color.

DC PROTECT (Short Circuit):

In the unlikely event the amp should internally fail, the amp will shut down to prevent a DC voltage output to the

speakers or sub and the LED will be Red in color.

Clipping:

While adjusting the amplifier the LED may light up Green indicating Pre-Clip, Amber indicating Soft-Clip or Red indicating Clip. These

indicators give the user a chance to identify incorrect settings or high distortion before it is damaging to the equipment allowing them to correct the

The Dual Mono Block amplifiers are capable of 4, 2 & 1 Ohm stereo and 4 & 2 bridged loads and can be used in any of the “bi-amplifier” systems described in the XXV-Juno and XXV-Gemini directions.

The XXV-Colossus has two 1600 watt D-Class channels built-in labeled L & R on the end panel.

SINGLE AMP INSTALLATION PROCEDURE:

1. Connect the amp LINE INPUTS to the Radio/CD player full range or mono line out puts 4. Connect a 2 gauge ground cable directly to chassis ground with in 36” of the amp.

with good quality RCA interconnect cables. - Be sure to remove any paint or primer from the ground point.

2. Plug in the XXVR-1 bass remote module into the amp REMOTE INPUT jack. - Use a nut, bolt and lock washer to secure the ground cable to the chassis ground.

3. Route a 2 gauge power cable directly to the vehicle battery with an in-line 300 amp fuse. 5. Connect the subwoofer(s) in accordance to the diagrams below.

This will allow you to operate separate subs independently (on each channel L or R) at 4, 2 or 1 Ohm at up to 1600 watts or bridged across L & R to operate a single sub up to 3200 watts at 4 or 2 Ohms.

Note: The amp is not capable of 1 Ohm when bridged across L & R.

12 Installation

The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. This section is intended to assist the installer by offering several tips and hints about good installation practice. Please remember that any system is only as good as its weakest link.

Design

Determine the system format, e.g., single amplifier, active, front/rear and so on. Then choose the amplifier power points to according to personal taste. Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to reproduce musical peaks cleanly without distortion. Lower power amplifiers will clip earlier than their more powerful cousins, and cause loudspeaker failure when overdrive, due to the harmonics generated by a clipped signal, thus overheating voice coils.

Choose loudspeaker and amplifier mounting locations. Loudspeaker location is always a matter of compromise between space and sound stage imaging. Amplifiers should be mounted with the fins running vertically for best convection cooling, to minimize overheating.

Purchase the best quality RCA cables you can afford, for reliability and less engine noise interference in the audio system.

General:

Mount the amplifier/s in the chosen location.

Run the wiring so that RCA cables are at least 18“ away from power and speaker cables. Keep RCA cables away from electrical devices in the vehicle that can cause electrical noise, such as fuel pumps.

Power and ground connections:

Use a sufficient gauge power cable, at least 4 gauge per class A/B and 0 gauge per class D amplifier. In a multi amplifier system, it is advisable to mount a large enough fuse right at the battery, and run a master +12 volt power cable to a fused distribution block near the amplifiers. It is then a simple matter to connect the +12 volt terminal of each amplifier to the distribution block.

Ground each amplifier with as short a ground lead, again at least 4 gauge per class A/B and 0 gauge per class D amplifier, directly to the vehicle chassis. Use a ground distribution block, if you wish, but it is extremely important to keep the main ground lead from this distribution block to the chassis as short as possible, not more than 12“. The ground connection integrity to the chassis is very important, and the best way to achieve a good, solid electrical and mechanical contact is to use a large round crimp lug, crimped and soldered to the ground cable. The next step is to scrape the paint off the vehicle chassis, slightly larger than the ground lug, at the connection point. Drill a clearance hole in the chassis, the same size as the lug hole, and use a bolt, spring washer and nut to securely fasten the ground lug. Use petroleum jelly to coat the bolt/lug connection, to prevent oxidization with time.

TIP: Use the same approach when installing head units, equalizers or any audio equipment for that matter - run short individual grounds from each piece directly to the

vehicle chassis, to minimize ground loops and system noise.

All power, ground and speaker connections should be crimped and soldered for reliability. Make sure that none of the cable insulation can chafe against exposed metal in the vehicle, causing short circuits to the chassis.

Safe connection sequence:

After all cables are run, connect speaker wires to the speakers and amplifiers, then run and plug in RCA cables. Next, connect all power grounds and remote turn on leads. Now connect all +12 volt cables to the amplifiers and distribution blocks and fuse holders. Finally, connect the main +12 volt cable to the battery, with the main fuse removed, and we are almost ready to power up the system.

Power up the system:

The following procedure may seem like overkill, but there is nothing more frustrating than turning on a system for the first time, and immediately it does not work properly. First, make sure the head unit is off, and turn all level controls to minimum (counter-clockwise), including the head unit volume control. Set all equalizers to 0 dB (no boost), and all crossover frequency controls at approximate frequencies, as recommended by the loudspeaker manufacturer. Set all input selector and crossover switches as required for the application.

Remove all amplifier fuses, and insert the main fuse at the battery. If the fuse does not blow, you can insert the fuse in one of the amplifiers, and we are ready to turn on the system.

Turn the head unit on, insert a CD, or select a radio station, and increase the head unit volume control. If the system sounds fine, turn off the head unit, and install fuses in the remaining amplifiers, one by one, till the complete system is powered up and functioning properly.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE

13

General:

As mentioned in the “General Installation Notes” section, the system should now be powered up, and working. At this point, all crossover frequency and input selection

switches should be properly set for the application, and all volume, level and equalizer controls turned to minimum. Level control setup:

Insert a CD or cassette that you are familiar with to use as a reference, and turn the head unit volume control to about 80% of its full setting to maintain an un clipped signal. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input sensitivities properly to the head unit output signal level.

Single 2 channel amplifier system (XXV-JUNO):

Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. Single 4 channel amplifier systems (XXV-GEMINI):

Turn the channel 1 & 2 level control up slowly, till you hear distortion, then back off a few degrees on the control. Repeat for channel 3 & 4.

2 or 3 way active systems (all):

Always start with the bass, or low frequency amplifier as a reference, by turning its control up to the point where distortion is audible, and back it off some. Now adjust the level control for the highs or tweeter channels in a 2 way active system, to balance the highs to lows.

In a 3 way active system, match the midrange level to the bass, and then the highs to the midrange and bass. It may be necessary to perform a few iterations of the midrange and highs level control settings to achieve a satisfactory sound balance.

Crossover frequency fine tuning:

We had started off in the “General Installation Notes” section by setting crossover frequency controls to approximate positions, and now you can adjust these for best sound quality. Be careful not to stray too far from those crossover frequencies as recommended by the loudspeaker manufacturer, as it is quite possible to damage midrange and tweeters with excess power outside their nominal operating frequency ranges.

Equalizer setup:

Once all levels and crossover frequencies have been set for a pleasant sound balance, we can start equalizing the system frequency response. It is important to remember that a boost applied at any frequency, or range of frequencies, will cause severe amplifier clipping. The following comments apply to ALL equalizers and tone controls on the amplifiers, as well as those on head units and dash mount equalizers.

Use the head unit volume control to adjust the system to an intermediate level, and proceed to adjust equalizers and tone controls to personal taste. Now go back to the

Level control setup above, and readjust all level controls.

Remote Bass Module:

Please understand that the Remote Bass Module (XXVR-1) is not a volume control, but rather a variable 45Hz Bass Boost. This module is intended for providing adjustable bass impact during listening. Turning the module all the way to the right or using it as a volume control can damage the amplifier, subwoofers or speakers in the system.
