The 16 channel 4 independent IEM Mamba Mix extension system enables a customer to expand 8, 12, 16 or more IEMs as the need grows. The input 16 channels from Main Mamba Mix system (Mic level or Line level) are passed to the Mix extension system via short cat5 cable. If you have more than one extension system then you can use a simple Ethernet switch to connect as many as extension system. All extension systems would receive the same inputs (16 channels) from the main Mamba Mix system. The 4 stereo mixes are available as balanced Mix out on a DB25 that is compliant to Tascam analog pin out as well as unbalanced TRS (direct headphone) for different application scenarios described. The key difference between Mix Extension system and Mic or Line Level Mix system is the absence of analog inputs as these are via cat5. Otherwise, all functionalities are identical to Mic Level Mix System. On the Mamba MIX16/4 App, you will be notified that there are multiple systems and you can select the unit that your Mix out is associated with. You can also name these Mix units so they are 1-4 and 5-8 Mix.

Each of the 4 stereo IEM mixes are output through a DB-25 break-out cable to a balanced XLR stereo pair for use with wireless IEM earphone systems, and headphones can also be connected directly to the TRS jacks on the front of the box. The Mamba Mix 16/4X extension box has no analog inputs, because all audio channels are input via CAT-5. When opening the Mamba Mix 16 App, you will be notified that there are multiple systems running, and you should select the unit that is outputting your personal IEM mix. Click on each tab for more information, and visit the Mamba MIX App page for a demonstration of the touch-screen App that performers use to control their IEM mix.
