About this file
This document is an Attachment J-4 Questions & Answers for a Library of Congress solicitation, dated 08/08/2025, addressing technical specifications for audiovisual equipment. Key details include camera and lens requirements, with the government adjusting lens specifications in section C.3.3, accepting alternatives to Sony control systems, and clarifying framing preferences (tight or medium shot) for a camera positioned 70-75 feet from the stage. The RFP's due date has been extended to August 15th at 5pm ET, and the solicitation involves specific technical preferences such as EZ RJ45 connectors, unbonded CAT6 pairs, and compression BNC connectors. The document also provides guidance on plate colors for wall and floor boxes, production monitor specifications (maximum 6RU), and confirms that certain proposed lenses are not compatible with the required 2x adapter.

Attachment J-4 – Questions & Answers *REVISED* 08/08/2025
1. Please specify the distance from the rear of the auditorium to the furthest object you plan to frame on the stage.
Answer: The distance from the camera in the rear of the auditorium to the stage is about 70 - 75 feet, depending on lectern placement.
2. Please specify what framing you expect relative to question #1. Is it a tight shot
(head and shoulders), medium shot (torso) or wide shot (head to foot).
Answer: Preferred framing is for a tight shot, but a medium shot including some of the torso is acceptable.
3. The 200 - 600 mm lenses specified exceed the payload capacity of the pan-tilt heads specified. The longest focal length that does not is up to 200mm. Is the government willing to accept this?
Answer: We are adjusting the requirement for the 200-600mm lens in C.3.3.
4. If the answer is no for question #3, is the government willing to accept a different manufacturer's control panel that may be outside of the Sony control system?
Answer: Yes. The control panel does not have to be a Sony control system but must meet all the requirements listed in C.3.6.
5. If the answer is no for question #3, is the government willing to accept a lens that is within the payload limits of the PTZ but under the zoom specifications of 200- 600mm?
Answer: Please see the adjusted lens requirement in C.3.3.
6. Are there any color requirements for the blank or custom engraved plates, i.e. black face plate with steel/aluminum reveal?
Answer: We would like the plates engraved. For the wall plates, these should closely match the current plate or the color of the wall since these will be visible to attendees. We can provide a paint code from the Architect of the Capitol (AOC). For the floor boxes, the custom plates can be black with steel/aluminum reveal, or another color scheme – since these will not be visible to attendees.
7. Production monitor - do you want the physical width of the monitor to be 19" or a monitor that is able to rack mount, i,e. Chief makes a rack mount for monitor bezels that are wider than 19".
Answer: We require a monitor that is takes up a maximum of 6RU, viewing area can be less than 19”.
8. BNC connectors - do you prefer compression or crimp and do you need tools
(stripers and crimpers/compression)?
Answer: Currently we have strippers and crimpers for 12G cable and would not require any tools. Compression connectors are preferred and would require a compression tool for 12G cable.
9. RJ45 connectors - do you prefer EZ connectors or non-EZ?
Answer: EZ connectors are preferred.
10. CAT6 - bonded or unbonded pairs?
Answer: Unbonded pairs.
11. Given that we don’t have the answers to these questions yet, can you please push back the due date of the RFP by one week, to August 15th at 5pm ET?
Answer: Yes, the Library will extend the due date.
12. Section J references past performance, brand name justification and photographs.
We are not sure what you are asking for, as these are usually associated with a integration project, and this is a box sale.
Answer: Section J is the list of attachments to the solicitation. These documents are provided to Offerors by the Library and are uploaded alongside the solicitation to SAM.gov.
13. Same for Section L, L.4 specifically, speaks to Volumes. There are no SOW's, as this is a box sale.
Answer: Volumes refer to the quote contents Offerors must submit to the Library as part of their quote. SOW refers to the Library’s SOW, which is Section C of the solicitation.
14. It is currently listed that the team needs Sony 70-200 lenses SEL70200GM2. The 70-200mm does not have power zoom, so you cannot control it through the camera. You can use external motors only. Other thing to note is if you use photo lenses and you put focus ring adapters on it, which is needed for the 70-200mm, the focus or zoom motors might slip due to the focus ring adapter.
I see that your teams would like to mount the cameras in hard to reach areas. The best lenses for the camera are these: Sony FE PZ 28-135mm f/4 G OSS Full-Frame Power Zoom Lens, Sony FE PZ 16-35mm f/4 G Lens.
Answer: The Kit lenses that this Offeror has listed are not supported with the 2x adapter, which is required. We confirmed this with a Sony specialist on these cameras and lenses.
