FAQ
Q: Will I be able to turn up the volume using my TV controller or will I need to adjust the volume manually?
A: If you use the TV variable output feed to the amp, you can control the volume using the TV tuner. Just set the amp to the desired level (and leave it there) and you are good to go.
Q: I want to drive 2 transducers, each 90 watts and 2 ohm, one on the L channel and one on the right. Will it work?
A: One can potentially use the two transducers, but they would have to be connected in series with each other. That would present an equivalent resistance seen by the Bluetooth audio amplifier as four ohms. Also, this Bluetooth audio amplifier is designed to deliver up to 200 watts RMS audio power at four ohms or 100 watts RMS audio power at eight ohms. So just place any potential desired electrical loads in series or parallel to give one at least four ohms or eight ohms, the desired potential resistance at four ohms with up to 200 watts RMS audio power at four ohms resistance or up to 100 watts RMS audio power at eight ohms resistance.
Q: My subwoofer connected to my receiver will still work?
A: You're using this and a receiver? The receiver has its own amp built-in. If that amp is dead and you're just using the preamp section of your receiver, it would depend on whether or not the sub is being powered by the same amp or if it's just using a separate powered sub output that just sends a low powered signal to the amp in the sub. Is it working from the receiver now? If so, it will probably continue to work.
Q: Is this amp stable with a 2 ohm load and if so what is the power output?
A: The Chinese manufacturers of this device have given a functional level of impedance as 2 - 8 ohms. The power adapter and/or the amplifier may get overheated because of heavy incoming current. Besides, the volume may be reduced with 2 ohm speakers. I am using 6 ohm Sony speakers without any issue.
Q: Is this device suitable for outdoor applications?
A: This device is not designed specifically for outdoor use, but it can be used outdoors as long as it is protected from moisture and extreme temperatures.
Q: I need to drive a total of 4 speakers. 2 left and 2 right. Each speaker is 4 ohms. Will this unit handle that?
A: Yes, this unit can handle up to two pairs of 4-ohm speakers connected in parallel, but keep in mind that the power output will be divided between the speakers.
Q: Are you able to turn off the bass to zero? (for listening to something like an audiobook or podcast)
A: Yes, you can adjust the bass and treble controls to zero for listening to audiobooks or podcasts.
Q: Can this be used to drive two subwoofers (the right input feeding the right sub, and the left input feeding the left sub)?
A: No, this amplifier has no subwoofer function. You can choose the M03 subwoofer amplifier instead.
Q: Can I connect my Pyramid preamp to this amp?
A: Yes, you can connect your Pyramid preamp to this amp as long as it has RCA line level output.
Q: Can this be used to gain a little volume with active/powered speakers, or is it too powerful?
A: No, this unit accepts a low-level signal and amplifies it. Active/powered speakers are already amplified and are incompatible with this unit.
Q: Is it bridgeable? If not, which model could?
A: No, this model is not bridgeable. You can order the TDA7498E mono amplifier instead.
