Product description The TTL33-A Mk II from RCF is a full range, ultracompact, wide dispersion, line array module for touring and theatre sound reinforcement. It is a 3-way active system featuring with 2 x 8" neo woofers with 64 mm voice coils in a horn loaded configuration, 3 x 1" neo compression drivers with 37 mm voice coils, titanium dome, in a horn-array configuration. Each transducer has been specifically designed for the application.
The 2 woofers provide large excursion and relatively very light weight, the midrange has an incredibly high BL for best vocal presence, and the compression driver design offers the minimum spacing between throats to avoid HF cancellation. Thanks 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, and an 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.
The TTL33-A II amplifier represents an execution of thought out, 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. and is responsible for crossover activity, equalization, the soft-limiters, RMS limiters, large signals compression and customized presets for the 3 way amplification.
The TTL33-A MKII is equipped with a dedicated networking board. Using our proprietary RDNet protocol, it 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 each and every cabinet or groups of cabinets, with specific presets or modifications of parameters like gain, equalization or delay, even on the fly. The RDNet protocol is based on RS-485 communication protocol, 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 and an On/Off switch. The cabinet is in marine Baltic birch plywood, coated with high resistance epoxy paint. The mechanical suspension and orientation system is in steel, very precise, and is relatively 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. Table of Contents
