This amplier allows to build a cost-eective multi-zone installation and mix music from analog
inputs with voice announcements.
A variety of features and wired connections makes this amplier a very versatile device with ability
to work in dierent applications:
• Multi-zone mono amplication for 100V speaker lines to deliver sound to many rooms (zones);
with an independent volume level.
• Multiple analog LINE inputs mixing.
• Compatibility with low-impedance speakers (selected models).
• Microphone input(s) with mixing for voice paging and broadcasting.
• Microphone input with priority (selected models).
• Chime to notify that a voice announcement is to be broadcasted (selected models).
• Treble / Bass regulation (one for all zones).
• Mono output to connect additional power amplier, subwoofer or powered speakers (selected
models).
• Signal and overload indicators.
• Cooling fan allows long time operation.
• Screw-in Speaker Connectors.
IMPORTANT REMARKS
Please read this instruction manual carefully before installation and keep it for future
reference.
• This amplier is intended for indoor use only.
• Because the 70V/100V technology requires adequate technical knowledge we
recommend having a licensed professional engineer or designer reviewed the design
and installation of the system focusing on safety and performance of the application.
• Model name coding TCA-###V.
◊ TCA - is the series name
◊ ### - is a number representing amplier total output power in watts
◊ V – means high voltage technology
For instance: TCA-240V is a high-voltage amplier with the total output power of 240
watts.
• This amplier is equipped in a ventilation fan which can generate noise – this is
normal operation.
• When switching on and o your audio equipment, turn down the volume to avoid
strong electrical impact to be delivered to the speaker.
Cleaning
Do not use strong or abrasive cleaners. Use a dry, soft cloth for cleaning.

Rack installation
This amplier is designed for installation in a 482mm (19”) width rack unit as well as can be used
as a tabletop amplier.
In the rack the amplier requires a space of 2 RS (2 rack spaces = 89mm).
• Hold the amplier by the handles in position and secure it in the rack with the four mounting
bolts (insert them in the rack mount holes).
• The mounting bolts alone may be not sucient for xing the amplier safely. We recommend to
use additional lateral rails or a bottom plate to secure the amplier in the rack.
Note! To prevent the rack from becoming top-heavy insert the amplier into the lower section
of the rack.
Note! Make sure that the hot air is dissipated from the rack – otherwise you may damage the
amplier and/or other equipment installed in the rack – this will void your warranty.

Speaker Connection
The Speaker Connectors can accommodate up to 10AWG speaker cables. A 10AWG
cable is recommended for longer connections (longer than 20 meters / 66 feet). For
shorter lengths you can use 12/14 or 18 AWG cables. It is recommended to leave
about 150 cm (5 feet) of extra cable at the amplier end to facilitate positioning and
installation of the amplier. Do not use staples, nails or other metal objects to secure
the cables. You will get the best sound quality and least amount of hum by keeping the
cables away from other electrical wires and cables.
WARNING!
• Before connecting the speaker make sure that the amplier is switched o -
otherwise you may damage the amplier and/or the speakers and void your warranty.
• Avoid to short-circuit of cables – it may damage the amplier and/or the speakers
and void your warranty.

This amplier can be connected to 100V or 70V speakers [100V or 70V mode] or low-
impedance speakers [low-impedance mode].
WARNING!
Never connect 100V and 70V and low-impedance speakers simultaneously - it may
damage the amplier and/or the speakers and void your warranty. Connect and use
only one type of speakers (100V or 70V or low-impedance speakers) at the same time.
100V or 70V mode – connection
WARNING!
• Make sure to use a 100V or 70V speaker for this mode - otherwise it may damage
the amplier and/or the speakers and void your warranty.
• Make sure that the total wattage of all connected speakers will not exceed the output
power of this amplier [check technical specications on the
www.tagaharmony.com website] - otherwise you may damage the amplier and/or
the speakers and void your warranty.
• 70V connection is not available for the ZONE OUTPUTS.
100V connection - using speaker cables connect 100V amplier speaker connector to
the 100V power input speaker terminal of your speaker (usually marked as 100V or
in RED color or +) and COM amplier speaker connector to the common input of your
speaker (usually marked as COM or in BLACK color or -).
70V connection - using speaker cables connect 70V amplier speaker connector to
the 70V power input speaker terminal of your speaker (usually marked as 70V or in
RED color) and COM amplier speaker connector to the common input of your speaker
(usually marked as COM or in BLACK color).
Speaker Connection
Low-impedance mode – connection
WARNING! Make sure that your speaker is suitable to work and is compatible with
the amplier working impedance - otherwise you may damage the amplier and/or the
speakers and void your warranty.
The low-impedance output is marked with Ω sign (usually 8Ω or 6Ω or 4Ω). Choose this
output if you intend to use a low-impedance speaker.
Pay attention to connecting the polarity of the speaker wire terminals correctly with the
amplier speakers connectors (RED + in the speaker with the output marked with Ω
sign in the amplier ; BLACK – in the speaker with the output marked with COM sign in
the amplier).
