    Our XA3200 is a powerful 3-zone multi-channel amplifier that delivers enhanced power to 5.1 home theater surround sound system AVR. This beefy amp includes three separate amplifiers in a single chassis. The beauty of this design is that your front speakers (left, center, and right) receive their own dedicated power source rather than having to share your AVR's power with other speakers. It provides the power necessary to hear the difference between the high-frequency sonic nuance of an orchestral triangle or the suspension of disbelief that comes from a realistic-sounding explosion or car chase. We like to remind our customers that our XA Series of multi-channel amps does more than just amplify a signal. Each amplifier includes advanced circuitry that cleans up power to reduce noise such as hum as well as improve overall sound quality. We also designed the XA3200 with two advanced heat sinks that allow the amp to run cooler and without the need for noisy fans. Add this amp to your component chain with a great set of speakers and brace yourself for a new reality in the surround sound experience.

    Advanced Class H Hybrid Amplifier Technology

    The XA3200 is a Class H amplifier that combines the benefits of Class A/B in a more efficient package. Class H amplifiers are a variation of Class A/B amps but include high voltage and low voltage rails to modulate power consumption. When power is running high, the amp switches to the high voltage rails. When the amp is running low, it switches to the low voltage rails. Many audiophiles swear by Class H because these amps can reduce dissipation across the output devices and allow the amp to operate with an optimized efficiency—regardless of output power level. This makes Class H amps a great choice for environmentally conscious customers, using less power than class A or AB amps.

    Flexible Connection Options

    The XA3200 high current home theater amplifier includes both balanced and unbalanced inputs for more flexible installation options and cable runs. XLR inputs (balanced) include a ground wire, which makes it a good choice for long cable runs, while unbalanced (RCA) provides a more reliable signal on shorter runs.

    Michael Bavaro • 01/13/2023, 10:12:51 AM Just wondering why there is no switch between XLR and RCA inputs. Does it automatically detect what is plugged in? All the other amps have the ability to switch between the two
    Customer Service • 03/21/2023, 2:34:49 PM
    I believe 90 percent of the time, people who buy this utilize unbalanced RCA inputs. I had a customer for whom I recommended XLR for channels 1, 2, 4, and 5 with hais center channel in unbalanced. 1 and 2 were running a bi-amp to his Klipsch Towers. His AVR had XLR for his front speakers only. So it plays either Balanced or Unbalanced, not both at once. Just plug and play automatically; it senses what you have connected. We are coming out with configurable multi-channel amps 4, 6, or 8 channel unbalanced only. TimL/3-23
    Michael Oleson • 04/23/2023, 9:50:38 AM From what I can see your warranty lasts 60 days with a restocking fee. Is that correct? Secondly, this is a pretty heavy amp for my shelves. Will heat be a factor? Does it get hot to the touch when driving speakers at a nominal level? Fan necessary?
    Customer Service • 05/22/2023, 2:40:09 PM
    Hi Michael: 60 days is our performance Guarantee allowing you to return the item if you are unhappy with the product. Or if you have an issue with it being defective. Depending on the circumstances, we may cover the freight back. The basic warranty for electronics is 1 year. After that, we will fix or replace it, but you will pay for shipping back to us. Typically the freight has been covered for you, and if a replacement is issued, shipment will be covered on that as well. TimL 5/2023
    Kevin • 12/02/2023, 6:42:35 PM Hi, I was wondering if your amps have a “soft on” feature.
    Customer Service • 01/10/2024, 4:31:10 PM
    Hi Kevin: Someone described the Turn-On as no Popping or no Turn-on Thump. There is no other description regarding a soft turn-on. TL

    Hi: The XA3200, XA5180, and the XA7180 have been discontinued. The re are being upgraded toa HTA4200, HTA5200, and the HTA7200. The 5 and 7 channel versions will be available by the end of April, 2024
    Paul • 12/15/2023, 9:23:48 AM Are the 5 and 7 Chanel AMPS discontinued?
    Customer Service • 01/10/2024, 12:31:18 PM
    Hi Paul: Yes, channels 5 and 7, as well as the 3 channels, are being discontinued. They will be replaced with upgraded versions in the second quarter of 2024. First, the HTA5200 and the HTA7200. A new four-channel, HTA4200, will follow by early Summer.
