Mackie SRM150 Portable, Personal PA System, New
The SRM150 is a handy, easy-to-carry portable PA in a box.
It has two inputs (each input will accept a standard XLR microphone plug or 1/4" instrument plug), as well as two RCA inputs (for CD players, etc.). It also has a phantom power switch, so you can use this with condenser mics.
With an XLR in/out on the back, these can be daisy-chained or used with other devices.
Each SRM150 also has a hole in the bottom for mounting it on a standard mic stand.
