CROWN XLS-2502 Power amplifier 2Χ775W/4Ω-2X440W/8Ω

Meet the new XLS DriveCore™ 2 Series

The next generation of XLS got a makeover with a sleek new look, a LCD display that is three times larger, and more DSP with higher capabilities. Like its predecessor, the new XLS is ultra-efficient with Crownʼs patented DriveCore technology and can drive 2400W at 4Ω bridged with tons of headroom guaranteeing a clean, undistorted signal straight to your speakers. The XLS DriveCore 2 assures that you will be heard as you deliver a powerful, pure sound experience for any venue.

• Class D amp with Crown's ultra-efficient DriveCore technology weighs less than 11 lb 
• Higher DSP capabilities: More control; has band pass filter per channel 
• Increased lighting functionality; turn off all LED indicators except clip and thermal to reduce distraction in dark venues
• Selectable input sensitivity; 1.4Vrms and .775Vrms options so that amp can be driven at full power
• Set sleep mode after specified time without having to press a button
• Security setting disables menu buttons; menu locked/unlocked by entering combination
• System reset allows factory settings to be restored
• Remote power trigger
• Peakx™ Limiters provide maximum output while protecting your speakers
• XLR, 1/4“, RCA inputs provide flexibility
• Integrated PureBand™ Crossover System for better performance and control
• Efficient forced-air fans prevent excessive thermal buildup

Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps.

BASIC Series - Intelligent Power

BASIC - that's meeting the tightest budgets and professional requirements
in reliability, flexibility and sound. Alone or in combination with the other
products of the Bittner portfolio.
The consequent realisation of the Bittner quality standards indicates once
more our understanding of the contracting business. It underlines our philosophy
that cost consciousness has nothing to do with giving up standards. Compromise
is a word unknown to Bittner Audio!
The incorporation of detent potentiometers, clip limiter, protection circuits for
any imaginable situation, as well as a first-class production process using only
highest-quality components made the BASIC series the choice of most contractors.

Certainly more than basic!

High Tech SMT design
Excellent sound and superior impulse response
