Review: Tech Pro Hybbrid.....good or bad ?????? - I dont ever get time to write reviews on things and is extremely rare that I do, As an audiophile sound user with my own home studio, have been in bands etc, I have the need to play my music at home with Godzilla belly rolling sub bass tones also without loosing clarity and sharpness of midrange & treble. I had looked at the very atractive hybrids on desertcart, read some not so good to bad reviews and eventually took the plunge and chosen the Pyle Pro 3000 Watt hybrid. It arrived and I was quite pleased with it except for loud fan running almost constantly when in use, Unfortunately it lasted aprox 2 months. So I sent it back through desertcart with full refund and no hassle whatsoever As I really liked the amp, after reading many reviews, I decided to take another chance on the almost simular Technical Pro HB2502U.It arrived from America quite quickly so I hooked it up to my 4x 300watt Pyle & Auna 15" speakers and the Pyle PTA3000watt power amplifier driving 2x 400watt Ekho 15" sub woofers.also using Beringer Ultragraph Pro 64 chanel EQ...............switched it all on............a few adjustments to EQ, amp, bass, treble and sub amp levels......balance the sub & pre output levels on the Technical pro amp........cranked it up and............ "YEOW"......I said ......"YEOWWW"..... this thing does what i would expect for price range despite bad reviews Hmm !!! Hmm !!!, .......OK.......not quite Hi Fi sound quality or the power it proclaims to be, but with the right setup ie: sub woofer & amplifier, its deadly enough with headroom to spare way before distortion levels would interfere with my required leves of listening volume. The truth is, seperately balanced volumes and frequecy levels is best if you intend to crank it up so loud that it all begins to sound like a lot of noise.....that is until you get some distance away from the speakers The many to mention features are as I would need espesially the seperate Pre & Sub outs which gives you balance control over the attached output amplifiers whilst the main volume being used as master control and the best part of all is its still going strong without any of the problems with the previously purchaced amplifer. More than powerfull enough for home or Small to medium venue use with seperate power amplifier for subs and would recommend above setup but......4 out of 5 for the amplifier due to no remote on /off good buy Review: Incredibly good buy - Bought this to use as an amateur DJ. Powers 4 professional speakers with great fidelity, almost audiophile quality. While it's true that you should buy amplifiers based on specs and speakers based on hearing the sound quality, you can't go wrong with this amp. I had been powering my good speakers with and old amp and just couldn't get good sound. This amp filled a dance hall for a 300 guest wedding, a 200 guest New Years Eve party, and many other dances. ## Features - 2 Channel Amp/Pre-amp/AM-FM Tuner (4 Main Speaker Output, 3 Surround Sound Speakers) 3500 watt maximum power - 2 rack space rugged metal chassis with handles- removable rack mountable ears included - USB / SD CARD / MP3 input / 2 mic inputs - RCA inputs & banana outputs - 2 mono RCA dedicated subwoofer output - 1 RCA dedicated preamp output- separate preamp and subwoofer gain control- Efficient forced-air fans prevent excessive thermal buildup - Microphone volume, bass, treble and echo controls - digital fluorescent output display meter- - 110-220V for worldwide usage - 2 Channel Amp/Pre-amp/AM-FM Tuner (4 Main Speaker Output, 3 Surround Sound Speakers) - USB / SD CARD / MP3 input / 2 mic inputs - RCA inputs & banana outputs - 2 mono RCA dedicated subwoofer output- 1 - Efficient forced-air fans prevent excessive thermal buildup - Microphone volume, bass, treble and echo controls - digital fluorescent output display meter - RCA dedicated preamp output- separate preamp and subwoofer gain control- 110-220V for worldwide usage - 3500 watt maximum power - provides a dynamic range that can handle the most demanding soundtracks without running out of headroom ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.4 out of 5 stars 16 Reviews | ## Images ![Technical Pro HB3502U Amplifier Equipment, Black - Image 1](https://m.media-amazon.com/images/I/71VNpji043L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Tech Pro Hybbrid.....good or bad ?????? *by L***E on January 27, 2014* I dont ever get time to write reviews on things and is extremely rare that I do, As an audiophile sound user with my own home studio, have been in bands etc, I have the need to play my music at home with Godzilla belly rolling sub bass tones also without loosing clarity and sharpness of midrange & treble.

Powers 4 professional speakers with great fidelity, almost audiophile quality. While it's true that you should buy amplifiers based on specs and speakers based on hearing the sound quality, you can't go wrong with this amp. I had been powering my good speakers with and old amp and just couldn't get good sound. This amp filled a dance hall for a 300 guest wedding, a 200 guest New Years Eve party, and many other dances. ### ⭐ Product has been good in past, but warranty sucks on new purchase......... *by R***. on June 5, 2017* This is the second hybrid amp I have bought from Technical Pro. The first one has been great up to about a year ago when the digital display started to fail and made the readout useless. I bought this one to replace the old one. This one is a higher powered unit which seems ok except for one of the channels giving the appearance of having a cracked speaker and therefore useless for it's intended purpose. We troubleshooted the issue and found that with different speakers, different speaker cables, different rca cables, etc it came down to the amp having a bad channel. I tried to return but it was too long after the purchase to be done through Amazon even though I had just opened the box that day for use, finally after a long winter. Contact with Technical Pro less than impressive. TP wants you to ship the unit back at your expense, and send them $30, for "shipping and handling. Some warranty. My $220 amp just became $280 if I want it fixed. I think I'll go with another brand and hope for a better warranty setup. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/10698777-technical-pro-hb3502u-amplifier-equipment-black](https://www.desertcart.tw/products/10698777-technical-pro-hb3502u-amplifier-equipment-black) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-23*
