Room A
Room A is located just outside the Council Chamber on the second floor to the south
of the Chambers vestibule. Room A has an existing AVC system in place. This, in
simple terms, consists of:
 Audio system – switched microphones on the Commission and staff desks,
DSP system, amplifiers, ceiling speakers.
 Video system – analog composite and RGBHV switching and distribution with
tie-lines to the control room, large LCD/Plasma displays, Video projector and
screen.
 Control system – AMX (older Axcess system)
 Wireless microphone and Assisted Listening systems
The intent is to replace the analog system components with a new digital system. A
new networkable DSP system shall replace the Shure audio mixers, and a digital video
matrix shall replace the analog switching. Current video displays shall be replaced with
new displays featuring LED backlighting and digital video inputs. Current video
projector and screen shall be removed. Current ceiling speakers, which are no longer
providing quality audio, shall be replaced with new models.
This room also requires a new pan/tilt remote camera system for Television Production
use. The new camera system shall be capable of both SDI and HD-SDI operation
(switchable). Four pan/tilt cameras shall be installed in the ceiling, with the remote
camera control unit located in the Control room. Cameras will require new AC power
supplies installed in the ceiling, as well as digital coaxial and UTP control cables run
back to the Control room. The AV design drawings show provisional locations for these
four cameras.
At the time of this design, no current As Built drawings for the Room A system were
available. It would be in the best interest of the AV Contractor to investigate this
further.
AV Rack Room
The AV rack room currently contains one AV rack. As very few items are to remain
from the current system, notably the Assisted Listening system, it is assumed that the
AV Contractor shall provide a new AV rack, with all the new components pre-installed
at their shop beforehand.
Audio
The existing cabling for speakers and microphones shall be reused. The Shure audio
mixer system shall be replaced with a QSC Qsys system. All audio channels shall be
connected to this, first passing through new audio patch bays, similar to the current
system in the Main Chamber. The Qsys Core shall be located in the Control Room
downstairs, with networked Qsys I/O Frames used for connections in the Room A AV
rack. All Qsys audio input cards shall be CIML4-HP – High Performance versions.
