Amplification: It is designed to drive passive speakers directly, typically offering power ratings such as 2 x 300W or 2 x 350W depending on the specific impedance (usually 4 ohms).
Phantom Power: It also provides +48V phantom power on its mono channels, which is required to "activate" and power condenser microphones.
Portability: As an "all-in-one" active unit, it is much more portable for small venues or mobile DJs since it eliminates the need for extra rack-mounted amplifiers
