Black Lion Audio AGB Compressor Limiter $1199 Black Lion Audio introduces another member of the BLA product line; the Black Lion Audio AGB Compressor Limiter . An homage to the venerable Neve 33609, the AGB is a two-channel diode compressor and limiter housed in a 2U rack mount chassis. Imagine a quick, responsive, low noise compressor with powerful control features. The AGB Compressor does everything from smooth and easy compression to weird rhythmic clicks to funky envelope tricks. It's insanely fast and doesn't choke when you really push it. Strap it across your drum bus and smash away. Give your snare a nice, dense crack. Use it for program material. The slower attack mode is great for vocals. Whatever you use it on, you'll find it does the job well, and without raising the noise floor. So where does their design differ from the original? For one, the signal path is a fully balanced, opamp-based circuit. Rotary potentiometers are used instead of stepped potentiometers, giving you more control over things like input level and attack time. Like the original, the Black Lion AGB uses input, interstage, and output transformers. |

Manley ELOP Limiter $2970 Set it and forget it! The Manley Optical ELOP Limiter makes your job easy. The principle of operation is based around using a rectified sample of the audio to shine an LED (Light Emitting Diode) onto an LDR (Light Dependent Resistor). The photo-resistor in combination with a fixed resistor simply act as a changing voltage divider to attenuate the signal &mdash like a smart volume control. A similar principle was found in the older Teletronix & Urei LA-2A, LA-3, and LA-4 units, which used a slower electro-luminescent panel-light on a conventional LDR encased in a light-tight enclosure. The Manley ELOP Limiter uses modern VACTROL technology (but with a trick!) for exact sample-to-sample tracking and no high frequency loss while digging deep into limiting &mdash problems commonly associated with older LA-series limiters and other opto-based units. The audio signal passes only through Manley's super-clean single-ended vacuum tube line amplifier. Due to its inherently quick attack, this Electro-Optical Limiter is a skilled soldier for tracking vocals or individual instruments, although now with the addition of a very useful sidechain high-pass filter that can switch between 100Hz or 200Hz (or OUT) to allow the limiter to ignore heavy bass lines, the Manley ELOP limiter is proving more useful for modern urban music where you don't want the limiter only responding to the loudest "thing" i.e., the BIG bass. If you want the bass line to leave the rest of the mix alone, then this switch is for you! |

Daking FET Compressor/Limiter $1445 The Daking FET 2 Compressor/Limiter is one of the best-sounding compressors around (because you don't hear it workingnone of the bad artifacts of compression, just the good), the Daking FET is designed to give you transparent performance along with the compression characteristics of highly sought-after vintage compressors well, stellar classics actually including the Neve 33609, Audio & Design Recording Compex*, and the venerable Fairchild 670. Note: The FET 2 is a single-channel compressor. However, for excellent stereo bus compression reminiscent of Neve, Fairchild, or ADR, two can be linked in stereo via a simple 1/4" -1/4" cable. Build quality The versatile Daking FET 2 Compressor/Limiter uses all-discrete transistor Class A circuits, the best transformers available, printed circuit board mounted switches and pots, and custom low distortion inductors. There is no audio in the mute, bypass, phase or pad switches. These functions are accomplished by relays with bifurcated gold contacts. Signal capacitors are precision polypropylene or ultra low-leakage electrolytic types. Circuit boards are assembled on a mil-spec assembly line. Only through-hole construction, not surface mount, is used to ensure long-term reliability and serviceability. The chassis are stainless steel for maximum RF and hum rejection and long-lasting finish. The faceplates are laminated with 10mil polycarbonate with the silk screening on the back so that the printing can never rub off. Every unit is hand finished, tested, burned in, and tested again. Also, Daking just couldn't stand to use plastic knobs, so they designed massive anodized, engraved aluminum knobs that give a much more precise and quality feel. * While Neve and Fairchild are more commonly known names in the recording industry, whose compressors have been used on countless classic and modern records for decades, Audio and Designs Recording is more of an insider's legend. ADR (Audio & Design Recording) is a British company that that made signal-processing gear in the '70s including compressors; one of which, the Compex F760FX, had a unique way of adding punch to drums. And of all the vintage compressors, is spoken about most highly in that regard. One version of the ADR compressor, the Vocal Stressor) was reputedly used on John Bonham's drums. Records such as the Knack's "My Sharonna," and albums by The Sweet, Pat Benatar (first album) had the Compex used in several roles. According to engineers who've used the original Compex, the Daking FET compressor does a fine job of providing the Compex punch.

Manley SLAM! Stereo Limiter and Micpre $6660 SLAM! stands for "Stereo Limiter and Micpre" and it pretty much describes what it will do to most VU meters. Manley had to put a switch on this limiter to drop its internal VU meters down 3 & 6dB to keep the poor little needles from bendingit'll get LOUD fast (hence the exclamation mark). And on top of being an amazing pair of (actually four) Limiters, and Class A tube mic preamps, it also has masters degrees in DI, AtoD and DtoA, VU and PPM but that was too much for an acronym. When it comes to classic gear, especially classic limiters, we can all agree numbers like LA2s, 1176s, 2264s, and others come to mind. What if all those sounds were to be found in one stereo tube unit. Interested? Manley combined their favorite Electro-Optical circuit (ELOP) with a fast FET based brick-wall limiter reminiscent of some cool classics. Manley added a sidechain filter that can remove low frequencies that makes it more useful for a variety of tasks, while retaining that easy, "it just works" quality that has made it a favorite for vocals everywhere. The FET-based limiter has different desirable characteristics that both optimizes the signal for digital recording, due to the brick-wall capability, and lets you dial in how clean or crunchy, or punchy, and how loud and proud you want it. Get in: The Manley SLAM! starts with tube mic preamps on both channels with switchable phantom power and phase reverse. Manley provided plenty of gain for you in this tube circuit, up to 60dB with 20dB more in the limiterplenty for soft singers using low output ribbon mics. The input attenuator is right up front, like a variable pad so your loud rock 'n' rollers won't cause a problem either. Track direct with the Direct Instrument input or bring your line level inputs into the Manley SLAM! for processing. Get it LOUD two different and distinct limiters per channel:The ELOP Limiter: Manley's beloved Electro-Optical Levelling Amplifier circuit, the ELOP, still the favorite for vocal tracking, shows up here with its switchable side-chain high pass filter making it much more useful for mixes and other tracks as well. One of the most appreciated aspects of Manley's original ELOP is the simplicity of a two knob limiter, which is optimum for demanding pro recording pressures. You can still grab two knobs and have complete control of level and dynamics and be ready to hit that record button. Intuitive controls and a straight ahead signal path through quality components simply works. The FET LIMITER: Here's a fast FET based "brick wall" limiter that spans the range of clean predictable limiting to the grunge and gravel that other FET-based limiters only dream of achieving. The FET RELEASE control allows you to dial up a variety of colors. There is even a "CLIP" setting that provides as round a shape as has ever been available. (Read more below about the CLIP setting |

Radial Engineering Komit Compressor Limiter $499.99 The Radial Komit Compressor Limiter is one of the eight modules designed to be comprise the Radial Workhorse Rack and Mixer System that combines the popular 500 series platform with an incredibly flexible patching system to let you create the ultimate studio environment. The Radial Komit is a feature-rich compressor-limiter that simplifies the process of dynamic manipulation while expanding upon creative tone shaping. At one end is a super-clean compressor that delivers amazing results with single knob control. At the other, an old-school diode bridge clipping limiter goes from 'vintage to nasty'. But don't let the minimalist approach deter; the Komit provides exceptional flexibility by integrating a series of automatic functions that are both musical and intuitive.The design begins with an auto-detecting feed-forward VCA that reads the incoming program material and reacts 'real-time' to the time constant. Set the 3-position attack-decay switch to slow for vocals, medium for instruments and fast for percussion. As you increase the ratio, the Komit FlexKnee compression dynamically adjusts the pivot point, seamlessly transitioning from soft to hard knee for more natural results. Yet unlike most limiters that are designed to be transparent, the Komit Clipper is designed to introduce personality to your recordings. The Clipper simulates the sound created by old-school diode bridge circuits from the early days of radio. These clip the input signal when they exceed the headroom. Same deal only here, you are in complete control. Ten settings are graduated from mild harmonic overload to extreme nasty. Think of Nine Inch Nails.To ensure absolute signal integrity, full size discrete electronics are employed throughout while the vintage style Hammond broadcast transformers add extra warmth to the signal path. A variable level control provides gain make-up or can be used to drive the Clipper for added distortion. Dual ballistic VU metering makes it easy to simultaneously view compression and output when making adjustments. Designed for use with all 500 series racks, the Komit can be linked for full stereo operation. When used with the Radial Workhorse, the Omniport is assigned as a key input for frequency dependent compression, de-essing, ducking or any number of dynamic manipulation effects.Applications:Channel StripThe Komit is the ideal compressor to compliment a 'gold' channel strip. Feed the mic into a PowerPre, an EQ and the Komit can keep dynamics under control for more professional results. Stereo programThe Komit can be set to stereo mode by linking two Komits together. This is great for mastering. And even though the two units will share the same time constant, independent compression retains the full stereo image. DuckingUse the key input (via the Omniport on the Workhorse) to automatically duck a guitar track (lower the level) when the vocalist begins to sing. Simply connect the TRS output from the PowerPre into the Omniport key input.Single dial |

1046 Quad Compressor Limiter $529.95 In today's recording and sound reinforcement environments, the need for multiple channels of high quality, easy to use compression is growing rapidly. The new dbx® 1046 is designed to provide the audio professional with just that: 4 channels of great sounding dbx compression for a variety of applications. Incorporating the industry standard dbx designs and the latest available manufacturing techniques, the dbx 1046 provides pristine sonic quality with that classic dbx sound. The 1046 provides 4 channels of smooth classic dbx OverEasy® or Hard Knee compression that are perfectly suited for use on individual tracks of your multitrack recorder, and in virtually all applications the separate channels can be individually interfaced and used for entirely independent purposes. Additionally the newly developed PeakStopPlus™ is ideal for protecting your system from the oppressive peaks that can take out valuable drivers in your sound reinforcement rig or studio monitors. All four channels have the following controls: Threshold - allows you to set the level at which the compressor starts affecting the gain OverEasy - allows you to select between soft compression for overall gain control or Hard Knee compression based on the characteristics of the original dbx 160. Ratio - allows you to set the slope of gain reduction affecting the signal over the threshold level. Input/Output Meter - allows you to set the meter to check the input and output levels for maximum signal-to-noise ratio and best level matching. Output Gain - allows you to add make-up gain or to adjust the output level for that channel to match the next device's input gain. Bypass - hard wire bypass allows you to hear how the compressor is affecting your signal. PeakStopPlus - allows you to set the maximum signal level you want to pass through this channel. While it's virtually impossible to eliminate distortion, the PeakStopPlus circuit does it gracefully and effectively with minimal distortion. Stereo Link - allows you to link channels 1&2 and 3&4 for two channels of true stereo compression. All four channels feature balanced gold plated XLR and 1/4" inputs and outputs, and switchable +4dBu or -10dBV operating level to interface each individual channel with any other device. So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 1046 is for you. |

Dell PA-9 adapter normally refers to the open circuit output voltage
First, the nominal voltage of power adapter Dell inspiron 1300 Adapter Dell PA-6 adapter Dell PA-9 adapter normally refers to the open circuit output voltage, that is, do not take any load, there is no current output voltage value. Therefore, that this is the power supply output voltage limit. For the internal use of the initiative power supply unit or voltage regulator components of the benchmark, in general the use of high resistance DC voltmeter can be directly measured nominal voltage (electromotive force should be a more accurate method of bridge belongs to the University of General Physics course experiment, not repeat them here), even if the mains voltage fluctuations in a certain place, is secure in its output a constant value; but for a small market, low-cost transformers, such as the Walkman and the like to the type used is basically the traditional magnetic core transformer with four rectifier diode bridge rectifier coupled with a large filter capacitor on the bin, and so if you use common dc voltage meter measured value will be greater than the nominal voltage, because the output of bridge rectifier pulsating DC, simply said to be a sinusoidal voltage signal is a half weeks of time connected chain, after going through the filter capacitor will become flat after some, but the ripple coefficient remains high (ripple coefficient is the same magnitude of voltage signal fluctuation the average voltage ratio, the smaller the closer description voltage direct current), the so-called nominal voltage refers to the time integral of this voltage divided by the integration time, simple to understand is the right time, on average, if an ordinary DC Voltage Meter , measured value is very close to the maximum value of the voltage signal, so uncertainty. At the same time, if the electricity fluctuate, the output of such power will change as well.
In general, the real average no-load voltage of the power adapter is not necessarily exactly the same nominal voltage, because the characteristics of electronic components can not be exactly the same, so it allowed a certain margin of error, civil cases according to the need to control the use of 0.1% to about 5%. The smaller errors, the consistency of demand for electronic components, the higher the cost of industrial production, the higher the price of course, the more expensive.
