CRESTAUDIO PRO5200 2X525W POWER AMPLIFIER

Pro 5200

Application
Designed with touring sound professionals in mind, the Crest Pro 200 Series power amplifiers
faithfully produce high power with low distortion in an extremely lightweight economical package.
Rock stable in stereo or bridged mode operation this series is engineered to exceed expectations,
when powering multiple or single loudspeaker enclosures down to a 2 ohm load.
The Pro 200 Series offer the protection that ensures safe & trouble free shows night after night.
Design Focus
The Pro 200 Series professional power amplifiers offer Crest's renowned sonic integrity while providing
exceptionally high power ratings (6500 W bridged on the Pro 9200) in a compact, lightweight 2U
package.
The Pro 200 Series amps feature Automatic Clip Limiting (ACL) to protect connected drivers; IGM
Impedance Sensing to accommodate varying impedance outputs; tunnel-cooled, high efficiency
heat sinksl and veriable-speed DC fans to limit the operating temperature and extend amplifier life.

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.

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.

A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling.  The integral soft clip limiter protects against damage to the connected loudspeakers.  The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.

A full model revision takes Yamaha's high-end PC-N power amplifiers to the next level - the PC-1N
Series. The new PC-1N Series amplifiers feature an extraordinarily solid low end, rich midrange,
and superbly defined highs. They also deliver fast response and exceptional stability even in the face
of serious power supply limitations. Refinements throughout this expanded five-model lineup make
these amplifiers the new benchmarks for quality, reliability, and versatility in professional applications.
Frequency Response: 10 Hz – 40 KHz. Output Power: 2 x 400 Watt / 8Ω RMS, 2 x 700 Watt / 4Ω RMS,
1400 Watt / 8Ω bridge RMS. Weight: 13 Kg.

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!
