## Questions & Answers

**Q: How loud is the fan for home use?**
A: I run this amp in a recording studio and it's dead silent.  Should be more than adequate for home use.  Good Luck!

**Q: Is it 110v or 220v? Or is it universal?**
A: The GXD8 has an auto-switching power supply and will work under 100-240V.

**Q: This item can work with Yorkville Elite E1152 1200 watts program?**
A: Yes, the GXD 4 would work well. I have no experience with the Yorkville enclosure but they do have a good reputation. Specs sometimes can be very misleading. Program power is a spec I question. This is a spec that was created for marketing since it always has an extremely high number that looks good on paper.

**Q: What are the power ratings?**
A: Number of Channels:	2
Power Class:	Class D
Watts/Side @ 8 ohms:	800W (Continuous, both channels driven), 1500W (Dynamic, both channels driven)
Watts/Side @ 4 ohms:	1200W (Continuous, both channels driven), 2250W (Dynamic, both channels driven)

### ⭐⭐⭐⭐⭐ These 2 Amps are completly different, and GXD 8 is the one to pick!!
*by G***S on June 7, 2019*

My adventure with these 2 amplifiers started with 40 year Phase Linear D500 developed a noise problem from leaky capacitors. Since my only local Vintage repair shop went out of business, I decided it was time to see what new innovations were available. My first foray was with the GXD 4. First impression was being blown away with the amp’s power efficiency, quiet fan and dead silent audio at idle. However, I was equally disappointed with the amp’s lack of dynamic range, and lack of Bass response and “punch” when used with full-range speakers. It almost sounded like a low pass filter was engaged, but the DSP menus assured me all filters were set to “Bypass”.Not wanting to give up, I decided to order the QSC GXD 8. What a difference!! I was completely blown away. The GXD 8 has the same quiet fan and noise floor as the GXD 4, but delivers full dynamic range and bass punch at any volume. Who would have guessed a class D amp could deliver near sub-sonic house shaking Bass that I thought was only to be found in old Vintage high-conductive transistor amps. The GXD 8 actually outperforms my old Phase Linear, in part because it delivers it’s huge Bass at nearly 85% power efficiency. Volume levels that would sag my home’s 15 amp circuit on the Phase Linear just sails by with the GXD 8. My only concern is this wonderful amp is being built in China, with circuit designs that might not last for decades (like My Phase Linear did). But for now, this aging baby boomer is in audio heaven...QSC GXD 4Pros>Whisper quiet fan when in idle. You have to be near the amp to hear it.>Residual noise is almost inaudible at idle, even with your ear right up to the speaker.>Only about 25 watts idle power consumption. Great for continuous use.>No in-rush surge current when powered on. Power up is smooth.>The DSP LPF settings include “bypass”, which removes the 20hz block filter found on other amps.>Very clean sound, but problems with Bass and Dynamic range (see below).>Useful as a side/rear channel speaker amp.Cons>Lacks both response and dynamic range in the Bass end below 100hz. You can partially restore the bass weakness with the DSP EQ, but the amp still completely lacks Bass “punch” so necessary for Home theater.>Not recommended for sub-woofer use.QSC GXD 8Pros>Whisper quiet fan when in idle, and only marginally louder when the amp is run at ½ power.>Residual noise is almost inaudible at idle, even with your ear right up to the speaker.>Consumes about 55 watts idle power consumption, and approaches 85% efficiency above ½ power.>No in-rush surge current when powered on. Power up is smooth.>Exceptional sound, dynamic range, and especially good Bass punch which the GXD 4 lacks.>The DSP LPF settings include “bypass”, which removes the 20hz block filter found on other amps.>Perfect for large power hungry front full-range speakers, or sub-woofer speakers.Cons>Power-on triggers 2 audible relays, which might become a reliable issue long term.>The entire unit is made is China.>The power supply design is like what you would find in a high-end computer. The reliability record on computer power supplies made in China is usually measured in years and not decades. Only time will tell if higher standards were used in building the GXD 8.

### ⭐⭐⭐⭐⭐ Very strong amplifier. Lightweight. Produces so very, very little heat.
*by M***N on December 27, 2023*

I am using this to power a pair of Ciare 18" subwoofers in large ported cabinets. For the past fifteen years I was using a pair of RMX850's, which were- yes- too small. Under such a load, these amplifiers ran hot, with fans running at full speed, even at moderate volume levels.This new amplifier is much more powerful, far better headroom, and the bass is much "tighter" than before. Very noticeably, this amp doesn't get hot, even with the sound level cranked up. Does it even have a fan? I don't see one. It may be fully passive-cooled.This amp has many built-in preprocessing features including a programmable crossover. A lot of amplifier for the price. QSC is putting a lot of effort into Class D amp design and it is paying off. I would buy again.
