TTL33-A II

LINE ARRAY MODULE

The TTL33-A II is a full range, ultracompact, wide dispersion, line array module that
sets a new standard in the touring and theatre sound reinforcement.
TTL33-A II is a 3-way active system featuring with 2 x 8” neo woofer 64 mm voice coil
in a bandpass low frequency configuration, 1 x 8” neo midrange 64 mm voice coil in
horn loaded configuration, 3 x 1” neo compression driver 37 mm voice coil, titanium
dome, in horn-array configuration. Each transducer has been specifically designed
for the application. The 2 woofer provides large excursion and very light weight, the
midrange has an incredibly high BL for best vocal presence, the unique compression
driver design offer the minimum spacing between throats to avoid HF cancellation.
Tanks to the extensive use of neodymium and new basket designs, the total weight of
the 6 transducers is less than 8 Kg!
The amplifier section features 750 watt switching power supply module, 500 watt low
frequency digital amplifier module, 500 watt midrange digital amplifier module, 250
watt high frequency digital amplifier module, extra capacitor bus able to sustain the
voltage for 100 ms burst signals. The total available power supply power is 750 watts
and can be distributed to the 3 final amplifier sections. Each amplifier section has
a very high maximum output power capability in order to provide, when necessary,
maximum output bursts in a specific frequency range.
TTL33-A II amplifier represents a state of the art execution of a Dsp controlled multiway
digital amplification. The analog input board offers xlr input and output link, cluster size control
switches, high frequencies correction switches, pre-loaded equalizations by-pass (memory
recall) switch and 4 status LEDs. Ethercon input and output connect the system in daisy chain
on a RDNet monitoring and controlling system from the FOH. The signal processor is a 32 bit
floating point Dsp running at 96 kHz. The Dsp takes care of crossovers, equalisations, soft­limiters, rms limiters, large signals compression and customised presets for the 3
way amplification. The TTL33-A II is equipped with a dedicated networking board. Using our
proprietary RDNet protocol is possible to monitor all the system parameters, from 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 AC panel features In/Out Powercon connectors, On/Off switch. A small fan, speed
controlled, guarantee the air circulation inside the amplifier in the most demanding
situations. The cabinet is in marine baltic birch plywood, coated with high resistance
epoxy paint. The mechanical suspension and orientation system is in high quality
steel, very precise and easy to use. The suspension system is directly connected
to the aluminum sides of the cabinet. The suspension system is designed to have a
safety factor 7 up to 16 speakers per side.
