Description
RCF TT2-A Active High Output 2-Way Speaker
The RCF TT2-A Active High Output 2-Way Speaker from RCF is compact, active and designed specifically for high-quality indoor and outdoor near field sound amplification. It is suitable for near field sound reinforcement, live sound, and corporate events.
It is equipped with 1600W digital amplification, of which 1100W are delivered from the low-frequency amplifier and 500W from the high-frequency digital module. The low-frequency transducer is a powerful 12″ hypervented neodymium woofer with a 4″ voice coil. A 3″ titanium dome compression driver loaded to a 90 x 50° dispersion constant-directivity horn provides high-frequency coverage.
With 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, equalization, or delay. Since the RDNet protocol is based on RS-485 communication protocol, it is stable and it is possible to send and receive data over a simple XLR cable.
The TT2-A features a multifunctional rear encoder to control all the speaker functions (such as gain reduction, delay, speaker presets) even without network connection. The speaker is equipped with a complete set of integrated rigging mechanics for rental or installation.
Amplification
- Class D Power
- Two independent digital amplifiers, 1100W for low frequency and 500W for the high frequency driver, deliver astonishing output power, making the TT2-A a powerful 2-way module. These class D amplifiers offer hi-fi sound, low distortion with negligible quiescent noise, and stable burst response
- Efficiency
- The amplification module is housed in a separate chamber and mechanically insulated from the cabinet vibration for reliability in long time operation. Thanks to the efficiency of the amplifiers, no fans are needed for quiet operation of the speaker
- Internal Processing
- The 32-bit, floating point digital signal processing at 96 kHz takes care of 2-way system crossover and transducer alignments, 8 programmable system equalization, programmable output time delay, input sensitivity reduction, soft limiter and gentle compressor for high signal inputs, RMS current monitoring and transducers protection, and input noise reduction.
A specially developed algorithm takes care of the frequency-dependent soft limiter, offering to the listener the same linearity of the system from very low level signals to the maximum output of the amplifiers
- AC RDNet In-Out Plug
- A dedicated processing area is available through the RDNet input board (sold separately). You have many options available on RDNet, including remote monitoring, special custom equalizations, high and low pass, single way solo and mute, and many other options
- Rear Panel
- The rear panel features a simple rotary encoder to control all speaker functions. A bright 7-segment clear display helps in changing the settings of the system. The only switch on the panel allows you to set to local or remote control. A simple command from RDNet totally disables the input panel to allow you to take exclusive remote control of the speaker
Components
- HF Design
- The HF transducer is a 3″ diaphragm compression driver with a 2″ exit throat. The pure titanium molded diaphragm offers sonic quality, extended to high audible frequencies, which ensures consistent power handling and reliability. The diaphragm and suspension are formed from 0.002″ (0.05mm) thick pure titanium. At the point where the titanium suspension is bonded to the assembly ring, a special dampening adhesive has been applied in order to further reduce and eliminate distortion creating resonances
- Direct Drive Voice Coil Assembly
- The voice coil assembly is designed using a high-strength, high-temperature Kapton voice coil former and a rectangular profile copper clad aluminum wire, and is assembled using specially formulated adhesives. Proprietary curing processes ensure assembly strength and safe operation even under extreme thermal conditions. The top of the former is bent and bonded directly to the edge of the titanium diaphragm, resulting in a Direct Drive configuration. Direct Drive ensures optimal transfer of energy between the voice coil and the dome assembly, providing extended frequency response beyond 10 kHz, reducing break up modes, and lowering distortion. This assembly delivers high power handling along with great mechanical and thermal properties that make the compression driver reliable and robust
- Woofer Design
- TT2-A’s mid bass transducer is designed to provide great frequency response linearity with very low distortion. A neodymium magnetic structure ensures precision and a 4″ voice coil design provides high power handling. The dual-forced air venting system ensures efficient voice coil ventilation to minimize the power compression and provide high power handling
- Inside/Outside Voice Coil
- The speaker uses a voice coil that combines the advantages of inside/outside technology and the quality of polyimide-imide materials (wire resins and formers resins). This inside/outside coil offers many advantages: the dissipation surface and adhesion area to the former is doubled. During thermal expansion, the former is squeezed between inside and outside layers, offering optimum mechanical resistance.
The inside/outside formers are made from polyimide-imide fiberglass and the area between the coil and the cone is a triple layer of Nomex-fiberglass-Nomex for optimum stiffness and accurate sound transfer
- Acoustic Design
- TT2-A features digital power amplifiers and a group of processing algorithms that, running at 96 kHz, take care of the speaker’s linearity and its dynamic control
Cabinet
- Water-Resistant Baltic Birch Plywood
- The cabinet is made with Baltic Birch plywood with every layer glued with special adhesive that makes the cabinet completely water-resistant even before the painting process
- Heavy-Duty Polyurea Paint
- Special polyurea paint is used to create a thick, full coating of the cabinet, making it highly resistant to scratches and bumps
- Heavily Braced Internal Structure
- The internal structure is heavily braced to survive long-term use and transportation and all the parts are assembled on metal inserts with metric screws. On the top and bottom of the cabinet, 2 large metal brackets are integrated for safe rigging day after day
- Handles
- The cabinet features 2 die-cast aluminum side handles, powder coated and with a rubber handgrip. Thanks to the internal scoop design, it is possible to use the handle in 3 different directions to facilitate transport, positioning, and loading
- Rigging
- The speaker offers many rigging possibilities: Top M20 insert; pole mount on the bottom; top and bottom fly tracks (6x); side quick lock pins (4x); side M10 rigging points (4x).
