Crown CTS 600 Crown CTS 600 Description: The power amplifi er shall be a solid-state two-channel model employing Multi-Mode® (AB+B) output circuitry. The amplifier shall contain protection circuitry which limits the drive level placed on the output devices before their SOA (Safe Operating Area) is exceeded. This protection circuitry shall calculate the instantaneous voltage across and current through the output devices while factoring in their simulated junction temperatures to predict how close they are to their operating limits. This protection shall be called "JTS." The amplifier shall contain protection from shorted, open and mismatched loads, general overheating, DC, high-frequency overloads, under/over voltage,and internal faults. If an amplifier channel starts to overheat, the Thermal Level Control (TLC) circuit shall engage that channel's input compressor in an amount proportional to the amount of overheating, in order to generate less heat. If the channel becomes too hot for safe operation, the channel shall shut off,and the Thermal Indicator for that channel shall illuminate brightly to alert the user that a state of thermal stress or overload has caused the channel to shut down. The front-panel control shall be a power switch. Crown CTS 600 Features: Rear-mounted controls shall include Channel Level Controls, High Pass Filter Switches (one per channel), and a Mode Switch. The High Pass Filter Switch shall select between fl at and two positions of rolloff. The twoposition Mode Switch selects between Dual or Bridge-Mono operation. The recommended load impedance in Dual mode shall be 2/4/8 ohms and 70V. The load impedance in Bridge-Mono mode shall be 4/8/16 ohms and 140V. The amplifi er shall be safe when driving any kind of load, including highly reactive ones.Rear-mounted output connectors shall be one four-pole touch-proof terminal strip. Rear-mounted input connectors shall be 3-pin balanced barrier connectors on the standard PIP2-BBY module. The module shall include a "Y" Input Switch which combines the input signals. The amplifi er shall be fully compatible with and shall provide appropriate input cables and connectors for Crown® PIP2 modules. The amplifier shall be fully compatible with Harman Pro System Architect and the Crown IQ System®. Front panel indicators shall include a yellow Bridge-Mode Indicator that illuminates when the Mode Switch is set to the "Bridge" position (and flashes if the Mode Switch is changed while the amplifier is powered up, indicating that the amplifi er must be powered off and on to reset the Mode), a green Ready Indicator (one per channel) that illuminates when the channel is initialized and ready to produce audio output, a green Signal Indicator (one per channel) that illuminates to indicate the presence of input signals above -40 dBu, a red Clip Indicator that illuminates when the THD of the channel's output signal rises to a level typically considered as the onset of audible clipping

Behringer REFERENCE AMPLIFIER A500 Behringer Reference Amplifier A500 Description: This ultra-linear power amplifier is the top choice for recording studios and post-production work, yet its amazing price is just the beginning. You get true audiophile-grade performance that delivers 2 x 230 Watts into 4 Ohms or 500 Watts into 8 Ohms bridged, with enough overhead to always keep you on the safe side. The A500's advanced convection-type cooling system guarantees stable, noise-free operation, while its servo-controlled design can drive virtually all passive speakers. A precise level meter and clip indicators are provided for accurate performance monitoring. Input connections are laid out on balanced XLR, 1/4'' TRS and RCA connectors, making sure you never run out of connectivity options. Plus, the speaker outputs give you a choice between professional ''touch-proof'' binding posts and 1/4'' TS connectors. To assure years of trouble-free operation, we only use the ultra-reliable Toshiba® or Fairchild® high-power transistors that are known for their rock-solid reputation. In addition to all these features, an independent thermal overload protection system with LED indicators for each channel automatically protects both your amplifier and your speakers. Last but not least, we have relied on a tough high-current toroidal transformer for absolute reliability and lowest noise interference possible. You and your clients deserve the very best in studio power amplification. Get the A500 and it will be love at first sight: it is super affordable, super effective and super flexible!

Current-feedback operational amplifier - The current feedback operational amplifier or CFB op-amp is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback (VFB) operational amplifier. The CFB op-amp was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.

Operational amplifier - An operational amplifier or op-amp is a very high-gain amplifier which has two inputs, one inverting (âˆ’) and one non-inverting (+). The output voltage is the difference between the + and âˆ’ inputs, multiplied by the open-loop gain:

Operational amplifier applications - This article illustrates some typical applications of solid-state integrated circuit operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown.

Differential amplifier - A differential amplifier is a type of an electronic amplifier that multiplies the difference between two inputs by some constant factor (the differential gain). A differential amplifier is the input stage of most operational amplifiers, or op-amps.
