## Description

Home Theater Amplifier

Review: 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.
Review: Great price, Amazing amplifier. I'm using it to power my Polk Reserve R700 speakers and it's incredible! I'm using the bridging option which pumps 400 watts into 8 Ohms and it really improved my system. I love OSD. If they keep making amps like this, I'll be a customer for life.
