The iFlex MAP-3 is a modular integrated DSP mixer. Compatible with all iFlex products and soft¬ware, and can act as an expander unit or as a stand-alone mixer. The MAP-3 accepts any three MAP modules for a total of 12 possible module channels. These channels can be audio inputs/outputs (including acoustic echo cancelling (AEC) inputs and FIR outputs), control ports, relays, or telephone interfaces. Combi¬nations of module channels includes 2x2, 2x6, 2x10, 4x4, 4x8, 8x4, 0x12, 0x8, 0x4, 4x0, 8x0, 12x0, 10x2 and 6x2 channels. The MAP-3 has a 16x12 routing matrix, and any channels not used by modules are available as network channels. This means that with network channels, the system can provide up to a full 16x12 channels. The MAP-3 is configurable through Sonatatm software, with the full suite of audio processing/routing/control functions of other iFlex mixers. The MAP-3 communicates with other iFlex products and software via Ethernet, and is powered by either PoE+ or external DC power supply.
