## Questions & Answers

**Q: How much noise does the amp create? I'm looking for a PA amp that needs to be very quiet in a small room.**
A: The amp is very quiet, there is no hum, I must iterate that all cables have to be the right resistance value on any amplifier no matter what brand you use just to make sure that all hum causing factors are eliminated.This amp will serve you fine and for the price I don,t think you will match it anywhere>

**Q: If i connect an ipod or phone to chanel A input will it play on both outputs for the speakers? Or only one side?**
A: only one side. You need cable 3.5mm to dual 1/4", then it will play on both speakers.

**Q: I owned 3 pair of this amp. 4500 musysics my question is can i use the  "input" 1/4" jack as "output" for interconection (daisy chain) 2nd. & 3rd amp?**
A: No. This amp doesn't have signal output. 1/4" is input. You need some sound processor or crossover to hook three amp together.

**Q: Cuantas libras pesa el amp?**
A: 20lbs

*by R***. on 14 April 2023*

I have owned this for a few months now and I have no regrets about buying it but I found that it needs a hotter signal to get it to the wattage point so I added a nobsound direct e6 tube preamps which I personally use in my home theater setup because the class d amps need more analog input to give them a warm sound and not so harsh on the higher frequencies and midrange frequencies are a lot better imho so I use them in my entire system all 9.1.4 so I don’t use my Denon AVR amps at all and the sys 4500 fit my old school DCM tf350s speakers very well because they are a 88db speakers and they need power and the amp fits the need and with a good amount of power left to boot. I am not sure how much power they are using but I am not able to get the amp pass 12 o’clock and at reference volume I can’t listen to them at this volume very long. I bought this amplifier because my speakers were starving for power and boy it definitely feeds them and I wasn’t expecting this Musysic SYS 4500 to work as well as it does but it works . I don’t know if I got the better built amplifier or what but it works great. The tube preamps definitely help with the sound and I’m sure it wouldn’t be able to produce the same sound without them. My room is a partly open concept but I haven’t been able to get the sound that I wanted until now so I’m pleased with the amp and I thought I would hate the blue led lights but I never seen them light up other than the time I set it up and so far it’s been light free even at high impact moments. My speakers are around 28 to 35 hz which is the other reason I why I bought the amplifier because of its ability to reach high 50k according to the specs weather that is true or false I don’t know , what I do know is that my speakers are now awake and that’s what I have been searching for. Overall it is a very good amplifier and I have no complaints except the fans are a little loud and I may replace them if my rack stays in the room which I have been working on moving it to my garage. Finally thought about the amplifier i know that having a dedicated outlet would be a great idea and it wouldn’t have to suffer from lack of power , so buy one and you are not happy with it then you can return it. BIG PLUS in my book even though it’s not perfect.
