NORTH PENN SCHOOL DISTRICT Lansdale, PA 19446 Planetarium Hardware and Software System Addendum #1 1. Bidders should bid systems that are compatible with the current audio system. Bidders should include in the cost of the bid audio connection to the current planetarium audio system.  The audio system is currently an analog, stereo system feeding four speakers located in the dome. The audio system is currently a two-channel stereo system. The audio inputs into the system are currently feeding into an audio mixer, we can take almost any type of analog audio connection; 1/4 inch, 3.5mm, XLR, or RCA. The audio mixer is located next to the equipment rack, next to the console. Cabling needs would be under 3 meters. 2. Minimum of 4.5 million pixels projected resolution must be supported by the projector. Kristin Johnson - Assistant Director of Business Administration 01/31/22 3:30 PM Page 1 of 2
