  • Page 4 Overview The Qt Room Control (QtRC) can be used to adjust the sound masking level for an individual room or a space with 2-8 emitters. This wall mounted volume control unit is designed to work with any of the Cambridge Sound Manage- ment sound masking systems.
  • Page 5 Qt Room Control Volume Settings The QtRC features a six position switch that adjusts the sound masking volume in approximately 2.5 dB increments. The volume will increase as the knob is rotated clockwise, with the maximum level at the 5 position as shown in Figure 5.1.

  • Page 7 masking level. In this situation, a cable can be brought to the room's QtRC and then connected to the emitters in the room, as discussed below. The QtRC will be able to decrease the power supplied to the emitters in the room, thus decreasing the perceived volume.
  • Page 8 another cable (shown RED) is run from the first QtRC's output jack, labeled "Out," to "In" on the QtRC to the next room. After installation, each room will have the same maximum volume while the emitters in each room can be turned down by each room's QtRC.
  • Page 9 (these cables shown in green). ( Figure 9.1 ) The cable that was extended down the hallway reaches a splitter that is used in the same way. A cable from splitter #2 goes to the next room, connects to QtRC #2 while another cable continues down the hallway.
  • Page 10 A Single Room: A QtRC from a cable run to an open area In the diagram shown below, the maximum volume for the room with an QtRC is the same as the volume of the emitters in the open area. The power supplied to all of the emitters in the open area is the same as the power supplied to the QtRC.
  • Page 11 The warrantor will, for a period of one (1) year, starting with the date of purchase, warrant that the Qt room control (the “device”) will be free of defects in materials and workmanship that interfere with its proper operation as a sound masking, paging and music distribution control system. During that period, the warrantor will, at its option, either (a) repair the device, with new or refurbished parts, or (b) replace the device with a new or refurbished device of equal functionality at no charge.
