About this file
This document is Addendum #1 for the Grand Ledge Public Schools Hayes Intermediate Renovations project, issued by HAV Design on April 25, 2025. The addendum addresses several product substitutions and clarifications for audio-visual equipment, including replacing specific QSC products with alternative models from RCF, Martin, and LEA. The document provides detailed guidance for bidders regarding wireless microphone packages for different school spaces such as the Gymnasium, Cafeteria, Choir, and Band rooms, and offers specific instructions on equipment placement and connectivity.
The addendum resolves technical questions about audio system requirements, including network connectivity for amplifiers, loudspeaker load considerations, and wireless receiver installation locations. Key modifications include replacing QSC E110 with RCF C 3110-96, QSC AD-C6T-LPZB with Martin C6.8T, and QSC MP-A40V with LEA CS124. The document also clarifies that the new audio systems do not need to integrate with the existing school PA system and provides specific details about wireless microphone packages for different spaces, such as using a Lightspeed wireless mic package in the Choir and Band rooms and a Shure SLX wireless mic in the Gymnasium.

Addendum # 1
General:
1. The following products from QSC included in the bid documents and specification have recently had freezes placed on orders:
a. QSC E110
b. QSC AD-C6T-LPZB
c. QSC MP-A40V
2. Please substitute the following products for those listed above:

b. Replace QSC AD-C6T-LPZB with Martin C6.8T
c. Replace QSC MP-A40V with LEA CS124
3. Other product substitutions for the above items can be considered
Questions:
1. In spaces where a feed from the school’s PA system is likely to exist currently (such as the Gymnasium and/or Cafeteria), should we be taking that into the new audio system and providing a priority ducker for that feed? Answer – The new audio systems do not need to account for an existing feed from the school PA system.
2. For the Choir and Band rooms (B108, B102 respectively), is the design calling for a Lightspeed or Shure SLXD wireless mic package? Answer – a Lightspeed wireless mic package should be provided for these spaces, one per space. See TA701 and Appendix A of specification 27 41 16 for model numbers, quantities and details.
3. For the Gymnasium and Cafeteria (B132, C113 respectively), can you clarify what wireless mic package the design calls for? Answer – In the Gymnasium, we are calling for one channel of Shure SLX wireless mic with a handheld and lapel transmitter sharing one channel. In the Cafeteria, there is an existing Sennheiser receiver and associated equipment that is to be re-used in the new system.
4. Is the Dalite Screen Controller an appropriate substitution for the Global Cache IP2CC- P? Answer – Yes, the Dalite device can replace the Global Cache device.

5. The QSC MP-A40V does not provide network connectivity for QLAN as shown in the drawings – how should we address this issue? Answer – Please provide connections from the QSC Core’s Flex channels as needed to supply line-level audio to the amplifier.
6. In the Gymnasium, there are loudspeakers wired to receive a 2.6 Ohm load. We have concerns about running into potential headroom issues there. Answer – The requirements for audio performance in the space are relatively modest, and the specified loudspeakers and loudspeaker wiring configuration should be enough to meet the needs of the space.
7. Where should the Lightspeed wireless receivers be installed? Answer – They should be installed on top of the projectors in the space and utilize the VJ-x conduit for wiring access to the main rack.
If you have any questions, please call.
