XXV 08 Amplifier Manual

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.

SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 150Hz.PARAMETRIC BASS EQ: CUT / BANDWIDTH: The bandwidth is fully adjustable from narrow to wide. FREQUENCY: The frequency is fully adjustable from 40Hz to 400Hz with a selectable X1 or X10 multiplier.CROSSOVER: The 2 channel amps have 2 crossover switches. One allows you to select HPF (high pass filter), LP/BP (low pass-band pass filter) at 12dB or 24dB mono. The second switch allows you to select mono or stereo operation while in LP/BP configuration. The 4 channel amps haveseparate CROSSOVER controls for channels 1 / 2 and channels 3/4. INPUT MODE: In the Ch2 position, all 4 amplifier channels derive their input signals from Ch1 & Ch2 Line Inputs (RCA). When set to Ch4, channels 1, 2, 3 and 4 receive input signals from Ch1, Ch2, Ch3 and Ch4 Line Inputs (RCA).

SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 35Hz.LOW PASS FILTER: The low pass filter is fully adjustable from 35Hz to 250Hz.PARAMETRIC BASS EQ: BOOST: The bass boost is fully adjustable from 0dB to 10db. BANDWIDTH: The bandwidth is fully adjustable from narrow to wide. FREQUENCY: The frequency is fully adjustable from 30Hz to 100Hz.MASTER / SLAVE: The mono amps (XXVThor / XXVCyclops / XXVGoliath, XXVSampson) allow you to electronically “link” two amps together so that you can power and single subwoofer with two amplifiers.

BALANCED INPUT: Accepts balanced line inputs from 0.2 volts to 18 volts for the optional MMBLD-1 balanced line driver.LINE INPUT: Accepts unbalanced RCA inputs from 0.2 volts to 9 volts.LINE OUTPUT: The unbalanced RCA outputs are set the same as the CROSSOVER switch on the front mount control and end panel.LEVEL: 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 andthe 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 thespeakers 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. Theseindicators give the user a chance to identify incorrect settings or high distortion before it is damaging to the equipment allowing them to correct thevolume or settings. REMOTE: All XXV amps have DIN cable bass remote jacks labeled INPUT. The XXVR-1 Bass Remote Module plugs into the INPUT jack and allows you to adjust the Bass Boost from 0 to 10dB.

BOOST: The bass cut / boost is fully adjustable from -10dB to 10db.

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.

SYSTEM DESIGN AND INSTALLATION

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.

Sit back and enjoy the music!

TROUBLESHOOTING A SYSTEM

14

The key to finding the problem in a misbehaving sound system is to isolate parts of that system in a logical fashion to track down the fault.

Description of the Diagnostic system built into all HiFonics amplifiersThe diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front/side panel PROTECT LED lighting up under the following conditions:1 - A short circuit on the loudspeaker leads.2 - An internal amplifier fault that causes a DC offset on the loudspeaker output.

Should the amplifier go into diagnostic mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic system.

Amplifier heatsink overheatingThe amplifiers will shut down when the heatsink temperature reaches 80 degrees centigrade, and turn back on once the unit has cooled down below that point.Causes of overheating:1 - Inadequate cooling - relocate or remount to provide better natural airflow over the fins.2 - Driving high power levels into low impedances - back off on the volume control, and/or make sure you are not loading the amplifier with less than the recommended loudspeaker impedance.

Low output power1 - Check that level controls have been set up properly.2 - Make sure that the battery voltage, as measured at the amplifier’s +12 volt and ground terminals, is 11 volts or more.3 - Check all +12 volt and ground connections.

Fuses blowing1 - The use of loudspeaker impedances below the recommended minimums will draw more current - check.2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.3 - If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier may be faulty.

System does not turn on1 - Check all fuses.2 - Check all connections.3 - Measure the +12 volt and remote turn on voltages at the amplifier terminals. If these are non existent or low, take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt and remote leads to localize the problem.

Noise problemsSystem noise can be divided into two categories, hiss, and electrical interference.

Hiss, or white noise1 - High levels of white noise usually occur when amplifier level controls are turned up too high - readjust according to the procedures in section ”Setting up systems after installation for best performance”2 - Another major problem that can cause excessive hiss, is a noisy head unit - unplug the amplifier input RCA cables, and if the hiss level reduces, the source unit is at fault.

Electrical interferenceThe inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system, alternator, fuel pumps, air conditioners, to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and ground. Remember to isolate the problem - first unplug amplifier input RCA cables, if the noise is still present, check the speaker leads, if not, plug the RCA’s back, and investigate the source driving the amplifier, one component at a time.

A ticking or whine that changes with engine RPM:1 - This problem could be caused by radiation pickup of RCA cables that are too close to a fuel pump or a distributor.2 - Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground.3 - Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash wiring/fusebox.

A constant whine:This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing oscillations in the system.1 - Check all connections, especially for good grounds.2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.3 - RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections.
