  • Page 4: Introduction

    The following pages include design, installation and operation guidelines utilized to reach the best possible performance from the Lencore sound masking system. The goal of a sound masking system is to provide speech privacy by raising the ambient background noise with a comfortable sound that is uniform throughout the space.

  • Page 5: Diagram

    Sound Masking Speakers The Gold system utilizes either 4" direct-fired or 6" in-plenum speakers. Direct-fired speakers are either mounted in the ceiling (Gold Direct Fired Tangent) or attached to the ceiling / deck (Gold Decorative Pendant) and face downward for direct, unimpeded delivery of the sound.
  • Page 6 See “Using the System” for detailed information. 7. IR Inputs Connect the IR input to a Lencore’s IR 3. Buttons device using an RJ45 cable for OP1 and OP2. The switches are used to make a number of adjustments to the system without using a 8.

    2. Connect a network cable to the unit’s Ethernet input to access the Protocessor. The Protocessor is the network server. The Protocessor is pre-loaded with Lencore’s System Manager. System Manager allows adjustment to the system’s characteristics. Note: The network cable must be a standard Ethernet cable not power over Ethernet (POE).

    Flow Diagram Back View *Diagram above is for wiring purposes only and is not an exact representation of the actual unit Gold utilizes both direct fired (Gold Direct Fired Tangent and Gold Decorative Pendant) and indirect firing (Gold Universal In-Plenum) speakers. Based on the space and the layout, each channel can accommodate up to 8 speakers per channel.

  • Page 11: System Zoning

    System Zoning Note: Lencore provides design layout at no cost. Speaker placement, zones and channel assignments are all complimentary as part of the Lencore design process. Contact Lencore today at 516-682.9292. Zoning is determined by the function of the space being served by sound masking as well as ceiling height. For example, separate zones are used for open offices, private offices, and corridors due to their requirement for differing sound masking volumes.

  • Page 12: Speaker Layout

    Speaker spacing is based on ceiling / mounting height. Lencore speakers have the same minimum and maximum spacing requirements from acoustic boundaries such as walls or columns. If a device is too close or too far away from a boundary, a change in sound level may be discernible by occupants and should be avoided.
  • Page 13 In many cases it will be necessary to adjust the last row or last several rows of speakers to compensate for room dimensions. In these cases, it is important to lessen the distance between speakers to maintain adequate coverage rather than increasing it.
  • Page 14 < 144 square feet Less than 1 Hour Above 14’ Call Lencore Less than 1 Hour In cases where the time duration of exposure, the room size is exceeded in reference to ceiling height, or the speaker location is offset due to ceiling conflicts, refer to Table 3 above for multiple speaker placement.

  • Page 15: Installation

    Failure to leave a 1RU of empty space above the unit can result in the unit overheating and eventual failure. Rubber feet are available to place the unit on a shelf or desk if a rack is not available. Contact Lencore for more information at 516-682-9292 or info@lencore.com. WALL MOUNTED 1.

    Optional Infrared (IR) Wall Controls Gold is equipped with two (2) integrated infrared eye ports, one for each OP. This allows for either a wall keypad or remote control with a wall IR Eye (both sold separately) to be used to adjust the system. Adjustments to the system may be made for the masking volume or the audio channel.

  • Page 31 Clicking on an OP will bring up the Controls and Tabs for that OP.
  • Page 32 You are able to adjust the masking volume and contour by moving the slider itself up and down, clicking the “Up”, “Down”, and “Mute” buttons or by clicking on the value and keystroking in a new number. Each channel is adjusted independently. Typically your final decibel level will be arrived at by adjusting both the masking attenuation (volume) and contour (frequency) controls.
  • Page 33 Zone Tab Zones are groups of OP channels. They allow you to combine and control multiple channels at the same time. The Zone tab, when first selected, presents you with a sub-menu of tabs for each type of zone available: Masking or Audio. Selecting either of these tabs will present a list consisting of all of the zones that have been added to the system for the selected zone type as well as a button for adding a new zone of the selected type. Each individual Zone item consists of the following information: • Grey “Zn” Icon • Zone # and Friendly Name. Friendly name is assignable once the Zone has been selected and will be blank if no Friendly Name has been assigned. Selecting one of the Zones will bring you to the Zone Editing screen which will allow you to adjust several attributes of the zone.
  • Page 34 The Zone Tab defaults to the Audio Setup where you can adjust the volume and the contour for sound masking (you can adjust the volume for the audio when in the Audio tab.) Use the sliders, the Up, Down and Mute buttons, or, highlight the values themselves and type in a value to adjust the volume and contour.
  • Page 35 NOTE: In most instances, the equalizer should not be adjusted unless there is a specific curve you want to apply. Lencore sets the masking at a comfortable curve out of the box. You have the flexibility to delete zones by clicking on the Delete This Zone link.
