• a PVS 305SA
• 4 PVT Wallplates
• 2 or 4 speakers (see "Speaker Configuration" in appendix B for details)
• an MLC 104 IP Plus with an IRCM DV+
• VoiceLift microphone system
• If an SCP 104 is used in the system, the MLC 104 Plus MUST have its
own power supply.
• The PVS 305SA provides sufficient power to run an MLC 104 IP Plus or
MLC 226 IP model.
