The Galaxy Audio JIB/MM (Multi Mixer) is a great tool for live sound, home recording, field recording, audio/video, and many others. This audio microphone mixer unit features 4 inputs; Chan 1&2: XLR/1/4″ combo w/ 20dB pad, Chan 3: Stereo RCA and Stereo 1/8″ mini (3.5mm), Chan 4: Stereo RCA. Each channel has its own volume control. 

The JIB/MM also features numerous outputs; XLR, 1/4″, stereo RCA, and a stereo headphone output with a volume control. The “Mic/Line switch” located between the XLR and 1/4″ Balanced Mono Outputs allows for selecting either a “Mic Level” Balanced Mono Output or a “Line Level” Balanced Mono Output. 

The JIB/MM will run off of 2 AA batteries for about 5 hours or an optional DC power supply (JIB/UA4.5-14). The JIB/MM will supply +24V phantom power to microphones. 

The JIB/MM is great for: 

  • Adding inputs to an existing mixer by creating a sub-mix of two or more sources before sending the signals to the main mixer or powered speaker. 
  • Serving as a sophisticated cable adapter that not only adapts the connector type but also provides the correct impedance with adjustable level control. 
  • Serving as the main mixer for solo or duo acts as well as AV presentations. 
  • As a mixer for rehearsals when its impractical to set up the entire PA. 
  • Interfacing pro audio gear with consumer audio gear. 
  • Battery operation allows remote location use where AC power is unavailable. 
  • As an emergency back-up mixer to have along just in case. 

Great for Use in Churches, Schools, and Bands.


Universal Power Adaptor JIB/UA4.5-14

Galaxy Audio is proud to introduce a new problem solver to its Audio Solutions line, the Universal Power Adaptor. The JIB/UA4.5-14 supplies 4.5v DC, at 1A to many of the new products in our Jacks In The Box line as well as most CD and MP3 players using the common 4mm barrel plug with center positive. The UPA comes with 4 different AC plug adaptors, and will accept any input voltage from 100 to 240v AC, 50-60Hz, which means it will work in nearly every country on the planet.
