6. igured with specific Port Mapping or Port Forwarding rules If for some reason Port Mapping is not possible e g the user has no administration access to the network Source Connect will attempt to negotiate the network Negotiation if possible at all is often slower and can create unwelcome delays and data loss because the UDP data must traverse an unknown and possibly temporarily available path And when this negotiation attempt simply attempt fails the user cannot receive the audio stream In addition if the ports are not mapped Quality of Service rules cannot be applied Therefore we recommend to all users that in a permanent studio situation they administer the network appropriately to allow proper UDP port mapping Using other port numbers Source Connect allows the user to specify a particular set of UDP ports First the user must configure their internal network settings to connect via a static IP rather than DHCP and then configure port mapping on the router For example the user configures the router to forward all incoming UDP data on ports 6000 and 6001 to their internal IP address and enters the number 6000 in the Settings Panel of Source Connect Ports may be any even number between 1024 65534 and this number plus one How Source Connect determines its network status 1 Source Connect determines the internal private local and external public IP addresses The external IP address is determined by s
7. incoming UDP data Source Connect has a good chance of making an incoming connection however if your Connection Test comes back port not mapped then you are likely to be able to hear the remote audio and only under very rare cases will your remote studio not be able to receive you Depending on the firewall Source Connect has about an 85 chance of making an incoming connection and about a 98 chance of making an outgoing connection If it comes back failed unfortunately Source Connect is probably going to disallow both incoming and outgoing data SEE MORE INFO IN APPENDIX VO2GO Kit Inventory Computer Computer power supply CEntrance Micport Pro w USB cable Pop screen kit with mount Mic mount arm w clamp Folding Mic Stand Sennheiser 416 Microphone Mic shock mount Headphones iLok USB key w Source Connect license Mouse Quickstart Assembly Connect USB Hub to PC Connect printer and iLok to USB Hub if needed Connect MicPort Pro directly to PC USB port Connect MicPort Pro to microphone Install mic in shockmount and attach to stand Power on or restart PC to ensure drivers load properly not always needed In Windows make sure CEntrance MicPort Pro is the default audio device for recording and playback In Mac OS be sure that Audio Midi Settings in the Applications Utilities folder are set for the MicPort usually 48000 sample rate must match recording settings in your software Be sure that whatever audi
