When you need a versatile line mixer, the new SM10 from Samson is sure to fit the bill. It features 10 channels with 1/4″ stereo line inputs (switchable +4 or -10). Each channel includes a balance control, and two of the channels also offer XLR mic preamps. There are two aux sends as well as main stereo XLR and 1/4″ line outputs, making it easy to patch in outboard gear and connect the SM10 to your main system. The rackmountable SM10 fits in a single rackspace and has an internal power supply.
