Each of the four mixer inputs has its own independent volume control, allowing the MMA130 to serve as a simple four-channel PA mixer. The sound coming from the speaker can be shaped using the three-band EQ. The anti-feedback control helps to prevent any feedback issues. Whether the performance calls for a single singer/player or a multi-player session, the MMA130 delivers serious audio quality in a variety of scenarios and venues. In addition to master volume, the controls on the side panel include a three-band equalizer with HIGH, MIDDLE, and LOW, allowing you to optimize your tone as appropriate for the performance venue. There's also an anti-feedback control that suppresses or eliminates acoustic feedback, allowing you to use the MMA130 with a microphone, acoustic guitar pickup, or any other amplified acoustic instrument.
The MMA130's rear panel provides two balanced mic/line inputs (XLR/TRS combo jack) as well as two more unbalanced line inputs (1/4" phone jack). The AUX Inputs accept a variety of sources: RCA phono plugs (L, R), a mini-stereo plug, and 1/4" phone plugs (L, R). This makes it easy to connect an MP3 player for a jam session, or use the MMA130 as a monitor speaker for your keyboard. The line output jacks provide a mixed audio signal taken from before the onboard three-band EQ, allowing the EQ to be effectively used to control the speaker tone, while the unaffected signal can be used for recording or sent to a larger sound system.
The MMA130 powered monitor amp will bring out your best performances in any situation, indoor or outdoor. With a truly professional array of inputs and outputs, as well as a four-channel mixer, it's incredibly versatile. The MMA130 can operate on batteries, and can also provide power to your musical instrument via a 9V DC output jack. In spite of the MMA130's portable size, it boasts an astounding power amp that projects an impressive amount of volume. The MMA130's versatility allows it to excel in any situation. It's a great choice for street live performances by a keyboardist or mobile DJ, and can also be used as a stage monitor.
