User questions & answers

Question:	I have a set of speakers already installed. can this bluetooth amplifier be used to power other speakers (i.e., other than the dual speakers
Answer:	We have not but the literature suggests “yes.” You would heed an interface to transmit the signal. This thing outputs pretty impressively fir its’s size.
Question:	can you control the amplifier from the bluetooth device. ie when the auxillary is used as an input
Answer:	The manual says only a U-drive is supported. I haven't tested this on my new unit, because I don't see how you could list and choose files.
Question:	Will this run a pair of bose 251 outdoor speakers
Answer:	Hello. No, it doesn't support aptx.
Question:	Will the amp power 4 speakers? 2 on the speaker outputs, and 2 on the rca outputs
Answer:	That's correct. I have one and the volume does not control the sub out.

User questions & answers

Question:	Can you connect to 2 5 watt speakers
Answer:	hi~friend of course ,it can connect 2 * 5w speakers
Question:	Would this work well with a pair of sony sscs5 speakers
Answer:	yes, I have mine hooked up to speakers and it works very well. This little amp has lots of power and I like the Bluetooth capabilities it has.
Question:	is there any way to improve the FM reception on this unit? Every station I get has static
Answer:	It's possible, but not always practical. Radio station static is often caused by RFI/EMI, a weak signal, or a combination of the two. You can skip a lot of steps if you happen to have some spare speaker wire, a small speaker, even an old car speaker, and a long extension cord lying around. If you have those things you just take the mini-receiver outside, and see if the radio reception has cleared up. If it has, then your home and/or something in your home is causing the static. A very simple fix that worked well with mini-bookshelf systems was to simply move the system, in this case the Archeer, closer to a window. Different building materials can directly effect radio signals, including WiFi. In fact, sometimes a radio in the same room as a WiFi router can cause interference. You can just to test trying turning off all the WiFi in your home, and see if the static goes away. Another quick option is to loop the antenna wire around the AC power cord as tightly as you can with the Archeer unplugged. Plug it back in, try the radio, and see if it helped. This was a popular method of improving radio reception of clock radio's. The antenna was wrapped like a spring around the power cord on the inside of the clock radio, so no visible antenna. If the FM is actually built into the Bluetooth chip, there is a possibility that you may improve reception simply by connecting a USB cable to the Archeer, and moving the cable to see if that helps. Certain Bluetooth receiver chips, like the CSR Harmony 4.0 had FM radio built into it. Along tghose lines, sometimes simply running spare wire, even very thin, cheap speaker wirefrom the receiver to a window, or up a wall can sometimes help. You don't connect the new wire to the antenna. You tape then together so that they're physically touching, but not the conductors inside the insulation. There is a formula to determine the length and gauge of a wire to extend an antenna for, in your case better reception, but I don't know it. Before digital cable one of the best options was to connect the cable directly to a receiver. If a receiver only had a single conductor, the center of the cable would attach to the connector, and the cable's braided shield would be attached to the metal backplate of the receiver using one of the screws holding the plate in place. Now with digital cable you may need an old school 300 ohm to 75 ohm cable transformer, or a capacitor if you wanted to try connecting the coax cable to the receiver. I never was into HAM Radio, but the people who are into it know A LOT about antennas and radio reception. They know about both problems and solutions. Unfortunately if you have brick or metal siding, you may need to move the unit next to a window.
Question:	Can the remote control control the volume
Answer:	Yes the remote can control the volume, its a nice little amp but don't expect some fancy remote, it works.

User questions & answers

Question:	Can the channels be bridged
Answer:	As I understand it, yes, since they have a common ground, you should be able to bridge them, I have not attempted this, but I will when I can, and will post result as a video review.
Question:	What is the frequency response to this amplifier
Answer:	Not exactly sure, I tested it for an ultrasonic animal deterrent I built at 24kHz and it worked great, I think I ran higher frequencies as well and it worked, but opted to run at 24kHz due to the dB loss of higher frequencies over distance. If that helps you at all.
Question:	I hooked up an arduino to this, and it does not work. connecting the arduino output to a home stereo aux input works, but not from this. any ideas
Answer:	I have yet to actually use mine, but I would expect the output impedance to be set up for 3 or 4 ohm speakers. Also, the output may have one side that is "common" and this would create a condition where you MUST get both outputs polarized correctly. Otherwise one will be a short circuit for the other. This would give you zero signal input to your next stage. "Line in" expects a different impedance, so you may have distortion even if you do get it to work.
Question:	Ti spec said tpa3116d2 is 2x50w or 1x100w. with two tpa chip it can be 2x100w. how does this board get 2x120w
Answer:	I believe this is an erroneous calculation based on the fact that it can drive 2 x 30W at 8 ohms, following ohms law once could calculate 2 x 60W at 4 ohms, however, to obtain 2 x 30W at 8 ohms, a duel layer pcb is required which this may have, I wouldn't know and don't have it on me, but still the claim is not supported by datasheet. Or maybe they calculated it by the figures 100W @ 2 ohm 24V and voltage max being 26V, but that doesn't calculate and is also not backed up by data sheet. Nice amp though.
