I have to turn it up way past halfway on the Master control and channel 5 to get loud enough sound from an attached computer or smart phone that balances with the Mic channel. This might be my inexperience using such sound equipment, but it does not seem right. More use will tell. I have recommended it to others because it is compact, portable, and easily set up / broken down. It does a swell job helping me to read poetry with recorded music in a coffeehouse that does not have quality sound reinforcement equipment.
