Iowa Public TV upgrades to SSL consoles
January 12, 2009
Iowa Public Television (IPTV), a statewide public broadcasting network with nine analog and digital channels, recently installed three Solid State Logic C100 HD digital consoles tied together through an SSL MORSE system as part of the station’s upgrade to high-definition video and surround-sound audio production.
The consoles service Control Room One (C124), Control Room Three in the Maytag Auditorium (C148), and a newly commissioned remote truck (C124), providing a uniform interface for the engineering staff and a seamless path for audio production from the station’s server.
The C100 in Control Room One is the primary production console for streaming audio to and from the server and producing the live in-studio programming like “The Iowa Journal,” “Iowa Press,” and a nationally syndicated show, “Market to Market.” The recently installed C100 in Control Room Three will service the station’s 300-seat auditorium with SSL’s Delta Link MADI HD, for Pro Tools capture and the house audio mix. The C100 in the remote truck is used for local sporting events and live broadcasts of concerts and events.
The MORSE (MOdular Resource Sharing Engine) pulls the entire audio strategy together by providing a central router in the facilities machine room that addresses signals from the remote stage boxes located throughout the station. Two remote mic/line preamps service the auditorium with 48 channels on one side of the stage and 16 on the other. Two remote boxes service the live rooms for show production, while three stage boxes exist in the machine room itself for additional patching capabilities.
The comprehensive display screens for monitoring and channel EQ and dynamics offered by the C100 allow the engineering staff to clearly understand the signal flow of a particular channel in the surround field, while providing an excellent visual verification of changes in EQ and dynamics. This capability helps IPTV as all audio production for surround broadcast is captured as discrete AES digital audio rather than through Dolby E or other matrix surround audio formats.
