    Lifetime Tech Support
Designing and building an amazing surround sound system begins with the right separates and paramount to the mix is the right multi-channel amplifier. This amplifier is a 5-channel Class H amp that supplies 180W per channel of clean power, and when paired with great speakers like ours, you'll hear music and movie soundtracks with exceptional detail, accuracy and warmth. The advanced circuitry, wide bandwidth, and low distortion capabilities of this amp allow listeners to hear spine-tingling sonic nuances, and this beefy amp can be matched with even power-hungry in-wall or freestanding loudspeakers. Designed with a high-output toroidal power supply and ample heat sinks to keep things cool, this amp has a clean, brushed metal finish and front panel status indicators that add a high-tech ambiance to any equipment rack.

Includes Balanced and Unbalanced Inputs
This 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 make it a good choice for long (up to 2000 ft) cable runs, while unbalanced (RCA) provide a more reliable signal on shorter runs. 

Advanced Class H Hybrid Technology
Our amplifier 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. The result is more efficiency, cooler temperatures, and a reduction in power consumption while maintaining the warmth and accuracy of a true A/B amp without the "digital" drawbacks (like interference) of Class D amps.

27 Questions asked on XA5180 5-Channel High Power Home Theater Amplifier Balance XLR Input 5x 200W Class H Power

Ed • 12/17/2019, 2:17:43 PM Q Can you connect this to a 5.1 receiver or 2 channel receiver? If you could, how do you do it? Thanks, Ed.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ed: This a straight 5 channel power amplifier with both Balanced (XLR) and Un Balanced (RCA) inputs. Its main purpose is to provide five channels typically more and cleaner power than you get from a typical 5.1 Receiver. Here is the rub, most 5.1 Receiver are more affordable than the more popular 7.2 Receivers. And in most case they only feature speaker high level output so you can not use this or any other external 5 channel amp. When you get into the $600.00 plus range you may find pre amp out typically RCA unbalanced. These are also 7.2 models that have 7 channels, 2 sub woofer pre amp out and usually a zone 2 and possibly a zone 3 connection also RCA pre amp outputs. Most AVR feature 95 or 115 watts per channel. You can connect the 5 channel to channel 1-5, Front left, center and right channels plus two surround channels. You have the option of running channels 6 and 7 - Side surrounds L & R or Height left and right for DOLBY ATMOS or DTSX directly from the speaker outputs of the AVR or you can add an external 2 channel amp like our new XMP 200 to the pre amp out puts. As far as connecting the five channel to a 2 channel amp it would depend on your application and again it would have to have pre amp outputs. You could connect to our Pre One pre amplifier with 2 channel pre amp output.You could use Y adapters to split the 2 channels to four channels then use four of the 5 channels. We have a six channel amp that you have more control on inputs and you have the ability of combining channels for more output. See our MX1260 amplifier. I hope that helps... TL/4975
Ronald Reid • 12/17/2019, 2:17:43 PM Q Where is the amp. manufactured? Do you ship to Barbados, West Indies?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ronald: The Amplifier manufactured in China to our specs. We do have a Master Distributor in Miami who covers the Caribbean, Central, and South America. They could ship from there either directly to you or through a freight forwarder of your choice. Let me know so I can supply contact information; tim@osdaudio.com. TL/5178
Tom Connor • 12/17/2019, 2:17:43 PM Q What is the Distortion rating on this amp at 8 ohms and at 4 Ohms driven?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Tom: Here are the official Specs: Total Harmonic Distortion Less than 0.02% at rated output (THD) (120W), all frequencies, less than 0.01% at 1kHz To be more specific to your question: Power Output 120 watts RMS x 5 (all channels are driven simultaneously into 8 ohms from 20Hz–20kHz with less than 0.02% total harmonic distortion, A-weighted filter) 180 watts RMS x 5 (all channels are driven simultaneously into 4 ohms from 20Hz–20kHz with less than 0.03% total harmonic distortion, A-weighted filter) TL/5180
Ronald Reid • 12/17/2019, 2:17:43 PM Q is the power output 150 w all channels driven?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Ronald: Officially this amp is rated 120 Watts 8 ohm and 180 watts at 4 ohms RMS with all channels driven. I also have a matching two-channel integrated amp if you need to add 2 or 4 More channels. It is under the Carver Electronics Brand, model M300. Identical output, ideal if you are looking to go 7 or 9 channels. You asked before if we ship to Barbados, we have a master distributor who services the Caribbean. tim@osdaudio.com TL/5184
James • 12/17/2019, 2:17:43 PM Q Is this Class A/B or Class D amp? Is 150W rating (8ohm) while all channels driven or one channel? Do you mind posting a picture of interior?
Customer Service • 12/17/2019, 2:17:43 PM
A HI James: Good Question. The XA5180 is a Class H amplifier a variation of a Class AB. Note, the definition I found online: There is a variety of amplifier designs that enhance class-AB output stages with more efficient techniques to achieve greater efficiency with low distortion. These designs are common in large audio amplifiers since the heatsinks and power transformers would be prohibitively large (and costly) without the efficiency increases. The terms "class G" and "class H" are used interchangeably to refer to different designs, varying in definition from one manufacturer or paper to another. Class-G amplifiers (which use "rail switching" to decrease power consumption and increase efficiency) are more efficient than class-AB amplifiers. These amplifiers provide several power rails at different voltages and switch between them as the signal output approaches each level. Thus, the amplifier increases efficiency by reducing the wasted power at the output transistors. Class-G amplifiers are more efficient than class AB but less efficient when compared to class D. However, they do not have the electromagnetic interference effects of class D. Class-H amplifiers take the idea of class G one step further creating an infinitely variable supply rail. This is done by modulating the supply rails so that the rails are only a few volts larger than the output signal at any given time. The output stage operates at its maximum efficiency all the time. Switched-mode power supplies can be used to create the tracking rails. Significant efficiency gains can be achieved but with the drawback of more complicated supply design and reduced THD performance. In a similar layout, a voltage drop of about 10V is maintained over the output transistors in Class H circuits. The picture above shows a positive supply voltage of the output stage and the voltage at the speaker output. The boost of the supply voltage shows for a real music signal. There is an image on our web page of the internal layout including the High Output Toroidal Power Supply. I believe the true power is listed as 125Watts RMS and 180 Watts at 4-ohm RMS all channels are driven. TL/5186
