[. . . ] This is a networked system using two AudiaFLEX 20x4CM units and two AudiaEXPO 8-Output Expander units (forty inputs, twenty-four outputs, CobraNet). An example system diagram is shown on the next page. Each courtroom is shown as having ten microphones. AUDIA inputs accept microphone or line-level signals equally well, so some inputs could instead be from sources such as playback of recorded evidence. Inputs from the four courtrooms are connected to the two AudiaFLEX units, which are located in a local equipment closet. Each AudiaFLEX unit accommodates inputs from two of the courtrooms, and provides four system outputs. In this case, one unit provides the outputs necessary to feed a hearing assistance system in each of the courtrooms. The other unit is providing the outputs needed for sound reinforcement. These outputs are feeding an MCA8050 multi-channel amplifier. The MCA8050 amplifier has eight channels which have been bridged in pairs, essentially creating four channels of 100 watts each. With four TDT100 transformers installed internally, the MCA8050 is prepared to drive the 70 volt distibuted speaker system in each of the four courtrooms.

This court recorder court recorder court recorder court recorder allows sharing of digital audio signals (CobraNet) and control data (Ethernet) on a network. Connected to the same Ethernet switch, and functioning as part of the same network, are two AudiaEXPO units. These two AudiaEXPO units are physically located in a central computer/recording office. The maximum distance between any AUDIA unit and an Ethernet switch is 300 feet. Therefore, this system can span up to 600 feet between the equipment closet and the computer/recording office. Additional Ethernet switches, or even fiber-optics, can further extend distances between units on the network. Each AudiaEXPO receives eight channels of digital audio via CobraNet, over a single CAT5 cable. These eight channels of digital audio are then converted to analog audio, and appear on eight separate output connections. Each AudiaEXPO provides the appropriate channels of audio for two of the four court recording systems. Mixing and processing of these signals (to achieve proper microphone/track assignment and consistent recording levels) has already be accomplished back at the AudiaFLEX units. Design example: Recording signals are not gated or equalized, but Levelers are employed to ensure consistent levels and intelligibility.
