## Questions & Answers

**Q: When using Bluetooth as the input, will the audio be output to all 4 channels simultaneously?**
A: Yes. in its simplest setup, there is basically Stereo, Left and Right audio channels, times two If you want it to work that way. OR, if you want/need to something more complex, you can change the mode of operation by pressing a button in the back, and have 2 separate Stereo feeds. One Stereo feed for channel 1 and 2, and a different Stereo feed for channel 3 and 4 by using the RCA jacks on the back. Its pretty well explained in the manual, and in the details of the Item Description if you cared to read it.

**Q: At low volume levels my unit cuts in and out, with an accompanying soft hum/beep. Before I ask for a replacement, ahs anyone else experienced this?**
A: Hello. Could you please send us a message on Amazon with more details? This issue may happen if the speaker power is too high.

**Q: Does this have sufficient power to power 4 Aura ast-2b-04 shakers?**
A: I have 35 watt ceiling speakers and the volume is very sufficient. You could always try it or send it back if it didn't work. Great amp for the price and very small footprint.

**Q: Is there a way to hook up a master volume switch to this unit, any ideas???**
A: Hello. You can add a volume control before this device. For example, https://www.amazon.com/dp/B07GRLV7XG?ref=myi_title_dp

Amazing product for the price! I've been using it to connect to my living room TV via Bluetooth, and power the passive speakers I have embedded to the walls and ceilings across some rooms of my house. I'm glad I didn't have to buy those $2000 home sound systems.
