ISOL-8 Minisub 2 Mains Power Conditioner Perfect working order. Good cosmetic condition with a few marks, mainly on the righthand side (see last photo). The marks are really only noticeable when brightly lit from the side - Manufacturers description - The ISOL 8 MiniSub 2 Mains Conditioner has permanent AV and digital filtering and other enhancements to bring it well ahead of the multi award-winning original. This is the first product in the ISOL-8 range that offers true immunity from component cross contamination. The ISOL 8 MiniSub 2 Mains Conditioner is housed in an attractively styled and mechanically stable chassis that matches other ISOL-8 products and looks good in racking with other professional equipment. Outlets 1 and 2 are specifically for power amplifiers, video projectors, subwoofers or any other product that may draw heavy, continuous or transient power. These outlets are served by a compound filter design; which, to avoid current restriction, is implemented solely using parallel components. Outlets 3 and 4 are specifically for analogue source components such as pre-amps, tuners, Phono stages or turntables. Outlets 5 and 6 should be used for any digital or video components such as CD player, DACs or DVDs, but can also be used for additional analogue source components. A complex filter designed around a huge, purpose-built low frequency choke heavily filters the mains supply. This then feeds 4 individual circuits, which discretely filter outlets 3 to 6, effectively reducing cross contamination between source components. All six outlets are optimised for different loads and are all protected at various stages against mains borne spikes. The neutral line is fused internally to protect the transient suppression devices between the neutral and earth. The live to earth devices are protected by an external fuse located in the IEC inlet. The front panel led indicator will show that the module is on and that both fuses are intact.

Monster Power Signature Series Home Theatre Reference Power-source. The HTPS 7000 is both a power conditioner and 3145 joule rated surge protector built into one. It is like new condition. Fully tested it works great as you can see in the picturesThe Clean Power Stage 5 provides the connected components with both isolation and filtration through 5 discrete filters, (with an extra pair on the digital inputs) to effectively eliminate line-borne noise anomalies and prevent components in the system from potentially contaminating one another. Whereas some line conditioners only treat power coming in, this still leaves the door open to cross contamination when power is coming back out. The HTPS 7000 eliminates this probability by isolating components. The front displays are dimmable.

I started my Signature Series in 2002 by introducing special versions of the Monster Power Automatic Voltage Stabilizer 2000, Home Theater Power Source 7000 and Reference Home Theater PowerCenter 5100. Each of these products represented a breakthrough in performance and affordability and included special enhancements for audiophiles and videophiles who appreciate minute attention to detail and elegant design...all geared towards getting the most from their home theater system. Now I am introducing my signature line of Monster Reference Home Theater Music Power Amplifiers for those of you who are passionate about movies and music. I’ve spent years perfecting this design working with renowned audiophile designers Richard Marsh, Demian Martin and the other dedicated professionals at Monster. After countless hours of critical listening and dozens of prototype designs, we have finally completed an amplifier that is good enough to be part of The Head Monster’s Signature Series. The Home Theater Music amplifiers are designed to please the most demanding critical listeners...like me! I like to listen to music LOUD with all the complex harmonics and dynamic range reproduced as accurately as possible. I also like to watch movies and to have the power and responsiveness necessary to reproduce movie soundtracks from the subtlest rustle of leaves to the most violent explosions. It takes a very special amplifier design to satisfy the needs of both home theater and music.I hope you enjoy your favorite music and movies even more with your new Monster home theater music amps.Monsterously,Noel LeeThe Head MonsterP.S. Here are some of the unique features of the Monster Home Theater Music Reference Power Amplifiers:MONSTER MIRRORED AMPLIFIER TECHNOLOGY™— (MMAT™)The MPA 2250 two channel, and MPA 3250 three channel amplifiers use a current-feedback topology we call MMAT™to ensure low distortion and greater clarity even at the highest playback levels. Any signal put into this amp will be mirroredat the output, just amplified, with all details intact. Monster amplifiers employ fully complimentary differential circuits, so the two halves of the amplifier are mirror images of themselves — helping lower noise and distortion.OTHER CIRCUIT INNOVATIONSAt the input end, a balanced complimentary push-pull stage delivers ultra-wide bandwidth performance for the best reproduction of today’s ultra high resolution 192khz DVD-Audio and Super Audio CD formats. Monster amplifiers are specially designed to be stable at high frequencies to support DVD-A and SACD.At the output end, high current MOSFET output transistors deliver instantaneous current for maximum transient impact. Monster amps provide high current peak delivery for a realistic, exciting home theater and music experience. of 37®Monster Home Theater MusicTwo Channel Reference Power AmplifierSignatureMPA 2250Owner’s ManualMonster Home Theater MusicThree Channel Reference Power AmplifierSignatureMPA 3250TABLE OF CONTENTSPageImportant Safety Instructions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .iIntroduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4Installation Guidelines . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5Connection Guide . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8MPA 3250 Connections. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 MPA 2250 Connections. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 Amplifier Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 Troubleshooting . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27Specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28Appendix A – System Connection Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30Appendix B – Amplifier Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32IMPORTANT SAFETY INSTRUCTIONSPlease read and observe the following safety points at all times:•Read these instructions.•Keep these instructions.•Heed all warnings.•Follow all instructions.•Do not use this apparatus near water.•Clean only with dry cloth.•Do not block any ventilation openings.

Monster Power Signature Series Home Theatre Reference Power-source. The HTPS 7000 is both a power conditioner and 3145 joule rated surge protector built into one. It is like new condition. Fully tested it works great as you can see in the picturesThe Clean Power Stage 5 provides the connected components with both isolation and filtration through 5 discrete filters, (with an extra pair on the digital inputs) to effectively eliminate line-borne noise anomalies and prevent components in the system from potentially contaminating one another. Whereas some line conditioners only treat power coming in, this still leaves the door open to cross contamination when power is coming back out. The HTPS 7000 eliminates this probability by isolating components. The front displays are dimmable. Comes with box only what you see is what you will get. of 37®Monster Home Theater MusicTwo Channel Reference Power AmplifierSignatureMPA 2250Owner’s ManualMonster Home Theater MusicThree Channel Reference Power AmplifierSignatureMPA 3250TABLE OF CONTENTSPageImportant Safety Instructions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .iIntroduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4Installation Guidelines . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5Connection Guide . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8MPA 3250 Connections. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 MPA 2250 Connections. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 Amplifier Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 Troubleshooting . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27Specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28Appendix A – System Connection Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30Appendix B – Amplifier Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32IMPORTANT SAFETY INSTRUCTIONSPlease read and observe the following safety points at all times:•Read these instructions.•Keep these instructions.•Heed all warnings.•Follow all instructions.•Do not use this apparatus near water.•Clean only with dry cloth.•Do not block any ventilation openings.

I started my Signature Series in 2002 by introducing special versions of the Monster Power Automatic Voltage Stabilizer 2000, Home Theater Power Source 7000 and Reference Home Theater PowerCenter 5100. Each of these products represented a breakthrough in performance and affordability and included special enhancements for audiophiles and videophiles who appreciate minute attention to detail and elegant design...all geared towards getting the most from their home theater system. Now I am introducing my signature line of Monster Reference Home Theater Music Power Amplifiers for those of you who are passionate about movies and music. I’ve spent years perfecting this design working with renowned audiophile designers Richard Marsh, Demian Martin and the other dedicated professionals at Monster. After countless hours of critical listening and dozens of prototype designs, we have finally completed an amplifier that is good enough to be part of The Head Monster’s Signature Series. The Home Theater Music amplifiers are designed to please the most demanding critical listeners...like me! I like to listen to music LOUD with all the complex harmonics and dynamic range reproduced as accurately as possible. I also like to watch movies and to have the power and responsiveness necessary to reproduce movie soundtracks from the subtlest rustle of leaves to the most violent explosions. It takes a very special amplifier design to satisfy the needs of both home theater and music.I hope you enjoy your favorite music and movies even more with your new Monster home theater music amps.Monsterously,Noel LeeThe Head MonsterP.S. Here are some of the unique features of the Monster Home Theater Music Reference Power Amplifiers:MONSTER MIRRORED AMPLIFIER TECHNOLOGY™— (MMAT™)The MPA 2250 two channel, and MPA 3250 three channel amplifiers use a current-feedback topology we call MMAT™to ensure low distortion and greater clarity even at the highest playback levels. Any signal put into this amp will be mirroredat the output, just amplified, with all details intact. Monster amplifiers employ fully complimentary differential circuits, so the two halves of the amplifier are mirror images of themselves — helping lower noise and distortion.OTHER CIRCUIT INNOVATIONSAt the input end, a balanced complimentary push-pull stage delivers ultra-wide bandwidth performance for the best reproduction of today’s ultra high resolution 192khz DVD-Audio and Super Audio CD formats.
