SECTION 1: INTRODUCTION
The TRI-PAK™ TS-110 is a high quality one
channel digital audio system delivering any
combination of music, paging and sound mask-
ing applications as a single zone in commercial
buildings.
The TS-110 is a low-voltage system installed directly
into the chassis of an Armstrong ESSENTIALS™or
PRIVACY™speaker panel in the ceiling plane. An
Armstrong speaker with a TS-110 installed on-board
becomes a self-amplified unit that can drive several
other speakers. (CAUTION: All wiring connections
must be made before powering up the unit.)
The DSP-based unit delivers one 10 watt channel
to selectable outputs at 25 volt, 70 volt, or 100
volt. A built-in digital noise generator provides
masking signals at either –4 dB per octave or
NC40 via switch selection. Multiple line/music
level inputs are provided. Switch selectable
equalization for the Armstrong P-25 and E-5
speakers is also built in.
Multiple TS-110 units can be linked together using
the balanced line outputs.

SECTION 4: INSTALLATION GUIDE
The TS-110 is designed for installation on the Armstrong P-25 or E-5 model speaker panels.
The set-up procedure is the same for each option. Follow these steps:
Remove cover plate from speaker and discard.
Place all input and output cables through knockouts and secure with strain relief. Leave
at least 6"-10" length for ease of connection.
Place conductors into terminal block plugs (provided). (CAUTION: Do not connect more
than two wires per contact position.) Tighten securely and place into appropriate con-
nector location on the TS-110 unit (as shown on page 3).
Connect speaker output at 100V, 70V, or 25V to main speaker and daisy chain or home
run to additional speakers. (CAUTION: Make sure that the switch-selected
voltage on the speaker matches the selection made on the TS-110.)
Turn TS-110 unit over and place enclosure into speaker panel and secure into place.
Use the mounting tab to place unit into the bridge at the center of the speaker.
Secure the unit to the speaker frame at the outer edge of the speaker with the screw
and speed nut provided.
Select the setup options desired for your application via DIP switches 1-8. (See pages
8-13 for additional information on specific masking, paging and music applications.)
Turn down the three volume control knobs on the side panel of the TS-110 (full
counterclockwise).
Wire AC power to the power supply (provided) and plug into AC power outlet.
Turn up and adjust the volume of masking, paging and/or music for your application.

SECTION 5A: SOUND MASKING APPLICATION GUIDE
The TS-110 provides sound masking via a built-in noise generator and includes a choice
of two pre-filtered noise signals: the industry recognized NC40 noise or a - 4 dB per octave
noise. Additionally, both speaker response EQs and space effect EQs are provided
to simplify the process of achieving speech privacy with a non-intrusive masking sound of
good tonal quality.
This unit can be used for either of the following masking applications:
1) One uncorrelated masking signal in a single architectural zone for open plan masking.
2) One uncorrelated masking signal in a single architectural zone for closed plan masking.
Caution: It is not appropriate to mix open and closed plan speakers for masking from the same
TS-110 unit because they are typically set at different levels and may be equalized differently.
FACTORY DEFAULT SETTINGS
The factory default settings are as folows:
•–4 dB noise pre-filter
•Normal noise level
•Armstrong P-25 speaker equlization
•Normal space equalization
OPEN PLAN SET-UP PROCEDURE
For an open plan application, the set-up process is as follows:
1) Turn the masking volume down on the side panel.
2) Set the desired masking signal with DIP switch position 1 where down is for the – 4 dB noise
signal and up is for the NC40 noise signal.
3) Set the speaker EQ for the P-25 on DIP switch position 3 by leaving it down in the default
position. (This setting provides an inverse P-25 frequency response thus making the system
flat relative to the speaker.)
4) Leave the space effects EQ at the default setting (normal) since an open plan space
probably has low space effects due to the sound at the listener being primarily direct sound
from the speakers.
5) Turn the masking volume up on the side panel. Using a sound level meter (SLM), measure
the sound in a cubicle or occupant seating area, adjusting the level until the masking is
approximately 48 dBA. Repeat this measurement in a few locations to ensure that the zone
is set properly.
6) You may choose to switch the space effect EQ to +1.5 to -1.5 or adjust the masking signal
to sound most pleasant or balanced to your ear. If either of these settings are chosen, you
will need to recheck the level in several occupant spaces and readjust the level to 48 dBA.

TS-110 Installation Manual - Page 9
SECTION 5A: SOUND MASKING APPLICATION GUIDE
CLOSED PLAN SET-UP PROCEDURE
For a closed plan application, it is usually recommended to have one P-25 model speaker
installed per room (unless it is a larger room, in which case as many as four P-25 speakers may
be used). The set-up process is as follows:
1) Turn the masking volume down on the side panel.
2) Set the desired masking signal with DIP switch position 1 where down is for the – 4 dB noise
signal and up is for the NC40 noise signal.
3) Set the speaker EQ for the P. 25 on DIP switch position 3 by leaving it down in the default
position. (This setting provides an inverse P-25 frequency response thus making the system
flat relative to the speaker.)
4) Set the space effect EQ with DIP switches 5-8, where the settings are listed in the
truth table on page 4. Choose the settings as follows:
• Normal: average sized room furnished in an average way (10x10x9ft, standard
acoustical ceiling (NRC .60), standard commercial grade carpet)
• + 3 dB: large room furnished with lots of sound treatment (20x20x9ft,
high performance ceiling (NRC .75), fiberglass wall panels (NRC .85) on 2 walls,
standard commercial grade carpet)
• +1.5 dB: large room furnished with some sound treatment (16x16x9ft,
standard acoustical ceiling (NRC .65), Mineral fiber wall panels (NRC .50) on 1 one
wall, standard commercial grade carpet)
• – 1.5 dB: small room furnished with little sound treatment (8x8x9ft,
standard acoustical ceiling (NRC .50), no wall treatment, standard commercial
grade carpet)
• – 3.0 dB: small room with no sound treatment (8x8x9ft, drywall surfaces, thin carpet)
5) Turn the masking volume up on the side panel. Using a sound level meter (SLM),
measure the sound at an occupant seating area, adjusting the level until the masking is
approximately 43 dBA.

SECTION 7: TROUBLESHOOTING GUIDE
Please follow these tips before calling Armstrong TechLine.
A. Review and follow all instructions in this manual.
B. Before terminating the speakers or speaker runs, verify the wire is clear of shorts, opens,
and cross-wires. Use appropriate equipment (i.e. a multimeter) to test.
C. If volume is too loud or too soft, check that speaker input/output voltages match.
D. If output sounds odd, check to be sure that the left and right input signals are not wired into +
and - inputs, respectively.
E. If you are still experiencing difficulty, please call TechLine at 1-877-ARMSTRONG
(1-877-276-7876).

SPEECH PRIVACY Refers to the lack of speech intelligibility from adjacent talkers. Several levels
of speech privacy are defined in the ASTM standards covering a range from
Confidential privacy meaning speech sounds can be heard but not under-
stood, to Normal privacy meaning that speech can be occasionally heard
and understood but is generally non-intrusive, to Poor privacy wherein all
adjacent speech can be heard and understood. These levels can be related
to ranges of a “Privacy Index” (PI) representing each level of speech privacy.
