Answer: There are 16 SLXD1-G58 Transmitters in the BOM, Wireless body

pack.

The 16 channels of new wireless receivers are shown connected using

both analog and Dante on the riser diagram. How are the analog

connections intended to be landed on the sound system inputs? Please

provide a one-line diagram indicating the complete wiring schematic

and/or operational intent.

Answer: Use the existing patch panel to land the microphones as per the

drawings.

The new wireless equipment is shown being added to an existing

rack of SLXD wireless equipment. What about the four channels of existing

wireless in the Main Rack? Is the new wireless equipment intended to

replace or augment the existing equipment?

Answer: It would be augmented, but check with client.

Is this wireless rack intended to be mobile? If so, what antennas shall

be used when the rack is moved?

Answer: It is in the existing rack, not mobile. Use the existing antennas.

Would the District wish to take advantage of the new SLXD+ wireless

equipment’s optional rechargeable battery packs and drop-in charge docks

for maximum performance?

Answer: Yes, if it is being replaced by the SLXD+.

We would recommend the RF VENUE D-ARC as the best performing

wireless antenna over the specified Shure ½ waves in this situation. Is this

acceptable?

Answer: Please use the Shure since this is what the client requested, but

suggest once awarded.

Sheet AV501, Detail 5 reads: “EXISTING IO PANEL, REMOVE VIDEO,

ADD 4 NETWORK, PROVIDE NEW I/O PANEL, KEEP ALL OTHER

CONNECTORS”. Would a new brushed/ anodized aluminum sub plate,

containing (4) EtherCon RJ45 connectors attached over the old video jack

location meet this requirement?

Answer: Yes, since it’s an existing IO Panel.

Sheet AV501, Detail 6 shows plate PR001, to be installed over center

stage, but the existing projector is mounted at the sound booth. Is this new

plate intended for a new projector to be added in the future?

Answer: Yes.

10.

A new Listen Technologies LT-800 ALS transmitter is shown replacing

the old Williams Sound ALS unit, but no ALS receivers or other accessories

are specified. What quantity and model receiver is required, and what

accessories shall be included?

Answer: The accessories are in the BOM, along with the LR-4200-072 Qty 16

which are the receivers, universal eye pieces, and lanyards.

11.

The artist's representation of the new sound system on the plans

cover page shows the center speaker cluster intact, which makes sense. The

existing system is set up as LCR, and the center speaker cluster is high

quality. However, the riser diagram does not include the center cluster. Will

the center cluster be removed along with the left/right speakers, or not?

Answer: The center cluster is existing and wired to the mixer. This does not

change. The drawings only show what is being added or changed, not

necessarily the existing system.

12.

Will the schedule allow for the above stage work to be completed

prior to the stage being demoed and repaired? If not, who will be

responsible for protecting the stage?

Answer: The Contractor shall include all necessary protection of the stage

during construction. The District will consider reasonable sequencing

suggestions from the Contractor to expedite the schedule; however,

protection of existing conditions remains the Contractor’s responsibility.
