User questions & answers

Question:	Why is it these listings are scared to list lumens? What are the lumens and why waste our time not listing it
Answer:	I have used it for rear projection, however it's suitability depends on the amount of ambient light in the room and the thickness of your projection surface. This projector is best in a room with little to no ambient light. If your intended use is a room with lots of light or a thick projection surface find a projector with 10x the lumens as this one at least, but expect 10x the price. Also the keystone on this is a maximum of I think 20 percent so with its resolution at max you need a cast distance of almost 1.5x your desired width so for a 20ft wide screen the projector would need to be 30ft behind the projector and that is a lot of wasted space.
Question:	Can this projector synchronize smart phone screen
Answer:	Yes, it will.
Question:	If there is no holder, how can i let the screen stand in my room? How can I hang it on plain wall
Answer:	the truth I never worked the wireless I am so sorry.
Question:	Do it have a remote control
Answer:	No

Q: Why the amplifier distortion when raising volume ?

A: Under normal circumstances, distortion is caused by the mismatch between the power of the amplifier and the speaker. Therefore, it can be reasonably matched according to the ratio of 1.2-1.5 to 1 between the power amplifier and the speaker

Q: How to match the amplifier and speakers reasonably?

A: The best match is 1.2-1.5:1 (that is, the speaker power is 50W, then the power amplifier power is 60W-75W)

Q: The power amplifier is connected correctly, why is there noise such as electric current?

A: please check whether there is current sound when no load, and whether there is no current sound when no load, please replace the audio input wire and input device. If there is current noise at no load, you can replace the power supply to test again

At the same time, confirm that the surrounding current signals will not cause interference to the equipment

User questions & answers

Question:	When i play videos directly from the projector's usb, how do i select a full screen mode
Answer:	Nope, that was one of the disappointing factor. However since it has hdmi, I would get a cheap android hdmi stick or just get the google chrome cast and you are set for Netflix and more. I use a Android tablet with hdmi and watch movies over the network via nas or xbmc.
Question:	Can i mount this mini projector on ceiling
Answer:	This projector is led based, meaning there is no replacement bulb. The led (light-emitting-diodes) serve as the light engine which is designed to last the life of the projector. According to the manufacturer the leds should last approximately 30,000 hrs. If they fail within the warranty period just replace the projector.
Question:	what is the image contrast ratio
Answer:	It is an awsome projector because it has a tv tuner, u can use almost any tv source etc. U can also put presentations or movies on a usb drive, just plug in the usb and play. You can also surf the net play YouTube, but it takes time as the input method is a slow process (No Keyboard). It has great color and at about 25 feet far away, you get maybe a 200 inch viewing. Now you have to have the room very dark as this is a low power (low cost to operate as well) the more light there is in the room, the more colors will fade from the picture.
Question:	Does this device play atmosfx sd cards on loop for projecting halloween or christmas decorations
Answer:	it is auto volt so it will accept voltages from 100 -240 Volts

User questions & answers

Question:	The appears to be 2 large capacitors - what are their temp rating and capacitance rating? What brand
Answer:	I've reverse engineered the circuit. The tubes are implemented as cathode followers post fade and feed the power amp inputs. The cathode follower implementation is a little strange in 2 ways: 1- Triodes are paralled but one plate is disconnected (pin 1) 2- Both channels are connected to B+ via a shared 220K resistor (haven't bench tested yet but CROSSTALK?!?!). Subwoofer outputs are on a separate path and not routed through the tubes.
Question:	Can i use this to power my front speakers and sub in a 5.1 through my avr that has pre-outs
Answer:	Hi Ryan J, Yes, the speaker system with 4 to 8 ohms will work with this AV Receiver. https://www.sony.com/electronics/support/res/manuals/4726/55cd375e0f9e7103f2b6baa747ed9072/47269061M.pdf (page 15 - Setting/Connecting Speakers) Regards, David
Question:	I read new stock due Oct will be sub controllable, the volume knob will control a subwoofer... has new stock arrived
Answer:	HI, Chris! Unfortunately, no. The Bluetooth feature of the receiver doesn't support connection of Bluetooth speakers. Regards, Erin
Question:	Are the tubes powering this amp, not just for show and is the sound warm when played
Answer:	Hi Allen W., The HDMI ports are actual HDMI inputs. You may refer to this link for more product information: https://docs.sony.com/release//SPECS/STRDH590_mksp.pdf ~Ralph
