Built-in mixer
At the very heart of the Mackie SRM150 PA System is a Mackie mixer, with all the versatility and features you’ve come to expect from the company. Channels 1 and 2 can be used for mic/line sources, thanks to the handy Neutrik Combo jack, which accepts either 1/4″ TRS or XLR connections. True 48V phantom power is supplied, so you can use even the most finicky condenser mics with confidence. You can also plug in your guitar, bass (or any other hi-Z instrument) into Channel 1, press the CH1 Instrument switch and you get all the benefits of a DI box, without the hassle and added expense. Channel 3 is reserved for stereo devices, such as MP3, CD, or tape players – a great feature for performers working with backing tracks.
