Minijack / AUX issues
Simple but we can not recommend AUX for tv use. Only for record and CD players or alike.
Poor audio quality
Our amps AUX input is set to volume 100 from the manufacturer. If you need to use the AUX we recommend buying our Lemus HOME remote, and set volume level to something between 30-50. This will improve audio experience by a lot. The TV output can also be of a very poor quality due to bad built-in DAC (Digital Audio Converter) and they are often made for headphones, not large stereo setups.
Also use a cable that is shielded. An unshielded cables are able to receive electrical interference that will be picked up by the amp SM450
High pitched tone when not in use
This is kind of an real issue that is being investigated. It has something to do with the fact that the amps AUX port is set to 100% from the manufacturer. Then it picks up some noise generated from the cable or AUX port, what then will not let the amp go to standby mode. We are aware. The issue can be solved by selecting another input on the remote.
How to adjust volume?
The Lemus HOME remote is neccesary in order to be able to adjust the volume.
Buzzing sound / noise
Use a cable that is shielded. An unshielded cables are able to receive electrical interference that will be picked up by the amp SM450
