My son has a BasX TA2 Stereo Preamp running 2 speakers and a BasX A2 Stereo Amplifier running 2 more speakers. 1st question: When my son turns on his TA2 the A2 will turn on as well but if he listens to music under volume level of 30 on the TA2 the A2 will turn it's self off after a while and won't turn back on unless he uses a volume level above 30. Is this normal? It's almost like it does not sense enough power to stay on. If he listens to music above level 30 it will stay on like it should.

With sensitive speakers, the output could be low enough such that it's not enough to keep the amp's Auto On engaged.
The Trigger can be used instead.

Oof. For subwoofers this low level used to be a problem and they had a subwoofer "boost" device for about $20-$40. I doubt audio quality was a notable features of those devices but I think they worked.

I am using the supplied trigger that came with the unit and it is set to auto.  hmmmm . . . My BasX amp has a On-Auto-Trigger switch, so this is not going to compare with yours with a Auto-On switch. I believe you have the Auto-On Switch set correctly with Auto. So please confirm the trigger cable is connected to the Trigger Input on the amp, and Trig Out on the TA2. It's easy to plug into the wrong jack, as I have done more than a few times. |

The switch needs to be in ON while using the trigger input. AUTO is for volume sensing.

If this is the case, then the manual is very poorly written, because as written it leads one to believe that Auto is for Auto Sensing and Trigger, and On is for just powered on until the amp is shut off manually. But yes, I second brutiarti's suggestion for trying with that switch set to ON. |

I'll take this opportunity for a generic rant against the Auto feature. I think it's a ridiculous feature and made even more so in the modern era of multichannel sound where a given channel may have no signal for seconds or minutes.
I have a Monoprice amp that I use for my rear surrounds. I knew that it didn't have a trigger input, but I solved that with a power strip that is turned on when another device that is triggered from the processor turns on. That works fine. The problem is ... this Monoprice amp has the auto sensing feature always enabled and it can't be defeated! So my rear surrounds were constantly missing the first couple seconds of some audible event and then coming on quite noticeably.
My solution - until I just decide to get another amp - is to turn the rear surround channels up +10db in the processor, then turn the volume control on the amp down a corresponding amount. This keeps enough signal running to the amp to keep it on most of the time that there is multichannel or upmixed content.

Maybe a solution would be to have an auto sensing feature that turns the amp off after an hour? That way you don't have to keep the amp on all the time or have to remember to manually turn it off? Does that make any sense? |

I have never owned, an Emotiva amplifier(at least not yet) but I did have this trigger issue similarly with my Velodyne HGS18 Subwoofer that has the auto sensing feature. All too often with the subwoofer will be enough passages to have a turn off and then back on again. Not a big fan of having that occur with a class D amplifier and ended up defeating it
