Review: Super satisfait - Super ampli, fonctionne très bien. Livraison rapide. Review: A well-built, great sounding amplifier with the ability to bridge channels - If you're looking for a powerful 2-channel amplifier or need a 4-channel amp with sufficient power for surround and/or height speakers, I highly recommend the HTA4200. I normally use a Lexicon LX-5 (5 channels with 200watts/channel @8ohms) to power my front, center, and surround speakers. Unfortunately, it needs service, and I don't want to burden my Marantz 7011 receiver with another 5 speakers. The HTA4200's big brother, the 7-channel HTA7200, received a glowing review in (now defunct) Sound and Vision magazine for both its build and audio qualities. The HTA4200 has the same per-channel power rating as the HTA7200 but offers something the 7200 does not: the ability to bridge channels. Right now, I have the 4200 set up as a stereo (300watts/8ohms per channel) amplifier. Everything is clearly marked on the back panel and only requires flicking a couple toggle switches. Just be aware that the (+) and (-) speaker terminals are now about 4 inches apart. So far, this amp sounds almost identical to my Lexicon which cost close to 10 times the HTA4200 (and that was 20 years ago!). This amp came double boxed with handholds on the outer one, something all heavy electronics should employ. I intend to return the HTA4200 to 4-channel duty when I get the Lexicon back. This amp is a fantastic buy compared to what you'll pay for a similar "name-brand" model. One thing that drove me nuts, and it's not explained well in the online manual. If you want to use the trigger function you must set the associated toggle switch to OFF. Note: I don't know if desertcart is aware of this but I'm sure manufacturers are, new FCC rules state that power ratings for amplifiers and receivers must be given at 8-ohms (not 4 or 6) with all channels driven at multiple points in the frequency range, not just the usual 1kHz. These rules have been in effect for almost a year now but there seems to be little compliance. Update: After using this amplifier in bridged mode for over a week, I have a better feel for its characteristics. First let me say that regardless of how loud I pushed this amp, it was never hot to the touch and the sound never harsh or distorted. As with most Class-AB amps, bridging two channels increases volume by ~6dB. While the amp produces detailed music with a wide soundstage, it appears to emphasis the lower frequencies. The bass is distinct, never boomy, but definitely more pronounced than the Lexicon or Marantz. I had to reduce the bass level for my front speakers because they have powered 8-inch woofers and are rated down to 34 Hz. I followed up with the surrounds which have passive 8" woofers with similar results. Next up were the surround backs (bookshelf speakers) with 5.5" mid-bass drivers. In this case, these speakers never sounded better, with a richer bottom end than either the Lexicon or Marantz ever produced. I then took the HTA 4200 out of bridged mode and used it to power 4 ceiling speakers with 6.5" drivers with similar results. I verified my subjective listening using Audessey room correction. Normally it puts the cut-off on the surround back and ceiling speakers at 80 Hz. With the HTA 4200 the cut-off was now 60 Hz (these speakers are rated at 45 and 47 Hz, respectively). In my opinion, while the HTA 4200 might not be a great match for floor-standing speakers with large woofers, it can really make smaller speakers come alive with its clean, powerful bottom end. Some may actually prefer its sound with large speakers. It's all a matter of taste. One thing for sure, you get a great-sounding amplifier with plenty of power for your money. ## Features - 4-Channel Class AB Amplifier: Delivers 4x200W (4 ohms) or 140W (8 ohms), all channels driven, for powerful, affordable home theater audio. - Bridged Mode Capability: Supports bridged mode with 300W output at 8 ohms and 1% THD, perfect for applications that require even more power. - Balanced XLR, RCA Inputs & 12V Trigger: XLR ensures low-noise, pristine sound; RCA offers broad compatibility; 12V trigger enables remote power on/off for seamless integration. - 110 dB SNR: Exceptional 110 dB at full power, 105 dB at 1W, for outstanding dynamic range and quiet performance. - 5-Year Warranty: Comprehensive 5-year warranty ensures long-term reliability and peace of mind for your investment. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CYK5HQXR | | Brand Name | OSD Audio | | Customer Reviews | 4.5 4.5 out of 5 stars (65) | | Date First Available | 25 January 2025 | | Included Components | Quick Start Guide | | Item Dimensions LxWxH | 43.4 x 42.1 x 16 Centimeters | | Item Weight | 32 kg 200 g | | Item model number | NERO-HTA7200 | | Manufacturer | OSD Audio | | Number of Component Outputs | XLR | | Output Wattage | 210 Watts | | Product Dimensions | 43.43 x 42.09 x 16 cm; 32.2 kg | ## Images ![OSD Audio Nero HTA4200 Multi Channel (4X) 200W/Ch Home Theater Amplifier, Bridgeable 300W/Ch - Image 1](https://m.media-amazon.com/images/I/61RUahSLGeL.jpg) ![OSD Audio Nero HTA4200 Multi Channel (4X) 200W/Ch Home Theater Amplifier, Bridgeable 300W/Ch - Image 2](https://m.media-amazon.com/images/I/51G4pECdqDL.jpg) ![OSD Audio Nero HTA4200 Multi Channel (4X) 200W/Ch Home Theater Amplifier, Bridgeable 300W/Ch - Image 3](https://m.media-amazon.com/images/I/41dLU9VLBsL.jpg) ![OSD Audio Nero HTA4200 Multi Channel (4X) 200W/Ch Home Theater Amplifier, Bridgeable 300W/Ch - Image 4](https://m.media-amazon.com/images/I/71NAl3PyJEL.jpg) ![OSD Audio Nero HTA4200 Multi Channel (4X) 200W/Ch Home Theater Amplifier, Bridgeable 300W/Ch - Image 5](https://m.media-amazon.com/images/I/71hjQOY70lL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super satisfait *by C***N on 18 December 2025* Super ampli, fonctionne très bien.

I've been running a Marantz Cinema 60 for a couple of years and have burnt the amplifier section up twice now, repaired under warranty. The Cinema 60 is rated at 100w per channel into 2 channels driven, or 70 watts x 7 channels driven. Turn it up to reference levels, 105-108 dB, and the amplifier would shut off from thermal protection. Not so with the HTA 7200. It will easily and cleanly drive my speakers 9 dB higher than the Marantz receiver can. Now I use the Cinema 60 as a pre-amp and let the Nero 7200 do all of the heavy lifting. Speaking of heavy lifting, the Nero 7200 is 64.2 lbs. It is twice as heavy as the Cinema 60 receiver + amplifier. It is truly a beast and the sound quality is no less than when I was using the Cinema 60 + integrated amplifier. Lots of clean power. No perceptible distortion or SNR background noise. No hot chassis or thermal shutdown after 1+ hours of music at high listening levels, just at the verge of perceptible distortion. If this unit can keep pumping out power like this for a few more years, it is truly worth the price tag. ## Frequently Bought Together - OSD Nero HTA7200 Multi Channel (7X) 210W/Ch Home Theater Amplifier - Primeda Auidophile 2RCA Male to 2RCA Male Stereo Audio Cable,Gold Plated | 4N Oxgen-Free Copper Core (2.5 Feet (0.75M)) - FosPower Banana Plugs 12 Pairs / 24 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/753955881-osd-audio-nero-hta4200-multi-channel-4x-200w-ch-home](https://www.desertcart.gr/products/753955881-osd-audio-nero-hta4200-multi-channel-4x-200w-ch-home) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-02*
