TT051-A
ULTRA COMPACT WIDE DISPERSION SPEAKER
DESCRIPTION
The TT051-A is an ultra compact, active loudspeaker designed specifically
for high quality indoor nearfield sound amplification. It provides surprisingly
high output and exceptional fidelity for foreground and background music
applications. It’s speech projection capabilities also make it very effective
as a fill or delay element in larger audio systems. Unlike many compact
loudspeakers, the TT051-A produces the high impact, high definition sound
projection expected in professional PA applications. Its wide angle projection,
110° conical, makes audience coverage easy in a variety of situations.
Special integrated side mechanics with a unique quick lock system has been
developed to provide a fast and easy set up of the speakers, offering an
outstanding application flexibility.
It is equipped with a 300 W class D digital amplifier, 150 W for the low
MAIN APPLICATIONS

frequencies and 150 W for the high frequencies. A powerful 5” neodymium
woofer and a 1” aluminium dome tweeter loaded to a wide dispersion
constant directivity horn provide an extensive coverage.
TT051-A features a 48 Khz, 28 bit DSP processing and a dedicated
networking board. Using our proprietary RDNet protocol is possible to
monitor all the system parameters, form the input to the status of each single
amplifier. Having a Dsp on board of each cabinet, it is possible to address
to single cabinets or groups of cabinets specific presets or modifications of
parameters like gain, equalisation or delay. The RDNet protocol is based on
RS-485 communication protocol, it is very stable and it is possible to send and
receive data on a simple XLR cable.
The state of the art TT051-A input board which features XLR In/Out, Volume
control, Eq. switch for wall mounting, Hi-pass filter switch, RDNet ready,
RDNet bypass, 4 status LEDs, Powercon In/Out.
Foam-backed grilles hide the drivers from view for pleasing aesthetics.
The cabinet features integrated quick lock mechanics to provide a perfect
stability during mobile events or easy assembling for permanent installation
