Spectra Gold User Manual
Lencore’s Spectra Gold unit is an out of the box, stand-alone system incorporating amplifiers,
equalizers, zone modification and total control in one unit. The Spectra Gold unit is a 1RU rack
mount unit that offers two OP’s and a head-end in one unit. The system maintains the easy to
use full one third octave band equalizer that can be adjusted to either individual zones or all
zones and provides exceptional fine- tuning capabilities. Groupings of sound sources and
channels let you customize an almost limitless number of zones for masking and music, while
maintaining the advantages of complete networked operation and control.
The Spectra Gold unit replaces all the bulky headend equipment that is associated with sound
masking systems. With the Spectra Gold unit there is no need for amplifiers, separate
equalizers, special switching equipment or matching vendors for compatible product interfaces.
The Spectra Gold unit’s technology is so sophisticated that it can allow zone additions,
modifications, deletions and other changes to the system on the fly without rewiring. This
eliminates the need for running multiple home runs back to the electrical closet or through
building risers to create separate or additional zones.
The Spectra Gold unit allows the ability to use up to 255 individual zones for masking and
music. The system’s easy to use full one-third octave band equalizer can be adjusted to either
individual zones or all zones and provides exceptional fine-tuning capabilities.
The creation, modification, addition and deletion of zones for sound masking and music can be
easily controlled using the included Lencore System Manager or through the on-board
switches. No proprietary software needs to be installed on the client’s side, eliminating security
and migration issues. The Lencore Spectra Gold unit is an open platform system. In addition,
volume and equalizer settings for sound masking and music can be programmed through
System Manager offering tremendous adjustment and control capabilities with unprecedented
flexibility.

Features and Capabilities:
The Spectra Gold unit includes many built-in features that used to require separately purchased
components.
•Data Entry Switches. The data entry switches allow the user to make a number of adjustments to
the system without using a computer.
•LCD display. The front panel display is used for displaying a variety of information.
•Two independent OPs in one unit for a total of 64 speakers on one unit.
•Two IR input ports to control each OP separately with IR wall plates.
•Protocessor. The Protocessor is used to control the networked system. The P r o t o c e s s o r
offers exceptional features, plus the flexibility to monitor and control the s y s t e m from virtually
anywhere.
•A single device for operation and maintenance.
•Ability to play background music.
•Eight independent speaker channels for a total of 64 speakers.
•An audio source input.
•Internal monitoring of system performance including the operation of the network, program,
memory, power, and characteristics of sound masking.
•Multiple, random sound masking sources, coupled with Lenore’s technology, produce a sound
quality that is random, making it exceptionally comfortable environment.
•Independent equalizers for unprecedented tuning where every channel of the system has a
separate and independent 1/3rd octave band equalizer or parametric equalizer.
•Sound frequencies and contour can be adjusted and set to any point on the acoustical curve, from
20 Hz to 20 kHz, making the first networked sound masking system to make fine-tuning the entire
spectrum of sound possible.
Installing the Spectra Gold
The Spectra Gold unit is designed to be installed in s standard 19” rack.
Use four of the appropriate screws designed for the rack to mount the unit.
Important. A 1RU of empty space is required immediately above the Spectra Gold unit for heat
dissipation. 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.

Wiring
Power and Network connections:
1. Plug the unit into a standard 115VAC power outlet. The system will be usable in approximately
two minutes. The AUX LED will flash while the system is booting-up and be solid when the
system is ready.
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).
Ground connection:
1. For future use in expandable interface solutions.
3

IR connections:
1. Connect an IR unit to the IR port.
IR1 for OP1 speakers.
IR2 for OP2 speakers.
Speaker connections:
1. Connect the external speakers to the appropriate channel using cat 5 RJ45 cables.
4

Auxiliary Connection
Connect an external device’s fault input to Aux “Fault Out” Relay R1 - NC and C. Relay R1 is energized
(closed) when no fault exists and de-energized (open) when a fault is active.
Input 1A and 1B are for future use.
Input 2A and 2B are for future use.
Configuring the System
The system must be configured before any paging or music functions are used. The switches can be
used to configure and adjust the system for many functions. System Manager must be used to create
any zones or to make more detailed adjustments such as equalizer settings. See below for switches
usage and the System Manager manual for using System Manager.
Front Panel Switches:
The switches allow the user to make a number of adjustments to the system without using a computer,
although, a computer and System Manager are still required for full control of all functions. A selection
can be made by continually pressing and releasing the switch.

Using the System
Front Panel Indicators
Audio Level
The Audio Level LEDs indicate the audio level input for the RCA music input. Low (yellow) indicates an
audio signal that is too low, Good (green) indicates a good audio level, and Clip (red) indicates a signal
that is too high, and clipping will occur.
PWR/SPL
A green PWR (Power) LED indicates that the internal power supplies are operating.
The SPL LED will be off for normal operation.
ERR/RUN
A red ERR indicates the Protocessor is in a fault condition while RUN indicates that the Protocessor is
functioning normally.
9

FLT
The FLT LEDs are indicators for system faults. The CPU LED indicates that the internal CPU
(microprocessor) is in a fault condition. The GEN LED indicates a general fault condition. When either of
these LEDs is on, a system fault has occurred.
Relays
Relay RL1 LED indicates a general fault. When the LED is on, no fault exists and Relay RL1 is energized.
When the LED is off, a fault has occurred and Relay RL1 is de-energized. AUX LED is for future use.
FTR1/FTR2
The FTR1/FTR2 LEDs are indicators for system inputs. FTR1 and FTR2 represent auxiliary inputs.
10

Neuron activity
The Neuron is a specialized internal microprocessor. The LEDs labeled TX and RX indicate Neuron
activity. These LEDs will be flickering under normal operation.
System Faults
Any system fault will be shown on the display by its fault code as shown below.

A fault can be muted or cleared. Muting the fault only silences the warning tone for 24 hours. Clearing
the fault can only be accomplished after the fault is rectified. See “Operation Examples” for more
information.
