The INT-1410 Audio Matrix is a PC/104-Plus audio peripheral board aimed for managing up to 8 analog input and 8 analog output channels, with programmable front-end audio CODECs, and up to 2 digital (S/PDIF) input/output channels. Other options include 2 auxiliary analog input and 2 auxiliary analog output channels with a programmable front-end audio CODEC.
The onboard PCI interface manages the 10-channel play DMA stream and the 12-channel record DMA stream of the main channels as well as the 2-channel play DMA stream and the 2-channel record DMA stream of the auxiliary channels.
The onboard features include a switch matrix that allows the user to select the driving source of each of the 8 analog output and the 2 digital output channels. A 2-channel mixer which can mix the 8 analog inputs, the 2 digital inputs and the 10-channel play DMA stream is also available as well as a 4-to-2 wire converter on an analog input/output channel pair.
Optional features include a two-way echo canceller on an analog input/output channel pair, a 1-watt power amplifier on an analog output channel and a preamplified microphone input on an analog input channel.
The board is fully compliant with the 2002/95/CE (RoHS) directives and can be qualified inside the standard (0 ~ + 60°C) and extended (-40 ~ + 85°C) temperature ranges.
