STAFF REPORT TO: Mayor Keis and Members of City Council FROM: Vanessa Van Alstine, Cable Television Producer DATE: July 8, 2016 RE: Cable System Change Orders Cable Producer Vanessa Van Alstine has had email discussion with Alpha Video Project Manager Jeff Merrill about the proposed change order CO0005 aimed at resolving the audio noise and radio interference issues with our new cable set-up at City Hall. The items with some brief explanations are as follows: • Change Order #5, items 1 & 2: These items add external phantom power for the condenser microphones installed at the dais. The BSS Audio digital signal processor system installed with the main part of the project has integrated phantom power, which is what we have been using. However, Alpha Video has experienced issues with the phantom power function on the BSS Audio units. Jeff Merrill, Project Manager with Alpha Video wrote in an email, “We have recently noticed on other projects that BSS has had some issues with phantom power introducing noise into systems. BSS denies that it is their issue, but we have remedied other sites by using external phantom power supplies and not using the internal supply in the DSP. We would recommend that we add external power supplies for the mics. These power supplies also have interference suppressors in them as well to limit radio interference.” This change order is for equipment only. While this labor is outside of the original project, Alpha Video has decided internally to waive labor charges for this work in light of frustrations resolving the audio problems. The cost of the ProCo phantom power supplies and mic splitters is $1130.40. • Change Order #5, item 3: This adds one additional cable retractor with a 5’ CAT6 Ethernet cable to the cable cubby installed at the dais between the City Administrator and City Clerk. The previous Change Order #3, approved at the April 27, 2016, Council meeting covered the box itself with cable retractors for HDMI and VGA + Audio connections. Adding the retractor for the Ethernet cable cleans up the rest of the computer connections cluttering the dais and provides a clean, unified package of connectivity. This change order is for equipment only given the labor was covered in the original contract. The cost for the CAT6 cable retractor is $350.00. In addition to the items on this change order, Alpha Video has provided in-line power adapters from Clock Audio for the new lavaliere microphones. This was a separate part number from the microphones, but it was Alpha Video’s error not to indicate it on Change Order #4, and they are taking responsibility for it. They have also decided to provide the duplicate on air/ready/off air indicator lights discussed with City Administrator Joel Hanson, City Clerk Heidi Heller, Council Member Rick Montour, and myself at no cost. Staff recommends approval of Change Order #5 totaling $1,480.40. Funding would come from the Cable TV Fund (#202).
