Product Description
The Power to Move You
Crown’s XTi family of amplifiers defines the standard for portable PA systems with unmatched performance, technology and power-to-the-people affordability that delivers the goods night after night without even breaking a sweat. There’s no debate — when you choose Crown’s XTi Series, you’re choosing one of the most powerful and efficient amplifiers on the market today.
How do we do it? With innovations designed to simplify your life and rock their world. Innovations like integrated DSP that allows you to quickly and easily configure crossovers, EQ, limiting and delay, along with tools like a pink noise generator, subharmonic synthesizer, and universal tracking switch-mode power supply, which reduces power draw and waste heat. And as the first Crown amps to use Icepak™ thermal modeling software, they are at the top of their class when it comes to thermal efficiency and lightweight portability.
The XTi Series demands respect without making demands on you. With this kind of freedom and reliability, the XTi family is one you’ll always want to be a part of. XTi. The power to move you — and the world

The new Wharfedale Pro Titan™ Sub-A15, a powerful active subwoofer system designed to produce high quality audio in any performance application. The Titan™ Sub-A15 combines the newest technologies, materials and design topology to ensure absolute accuracy and high output.
The TITAN™ Sub-A15 is powerful 15 inch band pass active subwoofer. A built-in 400 watt (continuous) 600 watt (peak) amplifier conveniently accepts stereo or mono line level inputs via dual, balanced, XLR-¼" "combo" connectors as well as a unique single channel 4Ω speaker level input via a ¼" phone jack which allows for use with a standard sound reinforcement amplifier (when the internal amplifier is not used).
A custom designed, down-firing, aluminium cast frame 15" woofer, with a 3" voice coil, is utilized as the heart of the Titan™ Sub-A15's complementary low frequency enhancement system. Integral signal processing includes a dynamic AGC (Automatic Gain Control) circuit, a stereo crossover and signal limiting for the prevention of a distorted signal to the internal amplifier. A convenient and an essential PHASE switch is included to allow for proper subwoofer signal polarity to be selected.
A pair of balanced XLR male output connections, with switchable "High-Pass" mode are available for the stereo line level outputs and may be used to pass through mono or stereo signals from the inputs to another system or to send a high-pass, line-level stereo signal to a pair of powered, full-range speakers such as the popular Wharfedale Pro Titan™ ACTIVE models.
| Applications: Because of its functional cabinet design, the Titan™ Sub-A15 is versatile and applicable in a variety of configurations. At home indoors or outdoors, on stage, in clubs, at rehearsals, in theaters and houses of worship, the Titan™ Sub-A15 will provide the high standards of low frequency audio reproduction that you require | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
