Building upon the legend of the seminal UREI 1176 compressor, the 576 FET Compressor from Quagliardi Pro Audio is a versatile compression module ideal for recording or mixing. With enhanced controls for modern versatility and Link control support for stereo processing (requires two 576 FET Compressors), the 576 is a vital tool for any 500 Series rack.

Basic controls include independent input and output gain, attack and release, and ratio control (between 20:1 and 4:1). A Mix control allows for onboard parallel compression, an extremely useful modern feature. Further special controls include an XREL switch for selecting between two different transformer coil configurations, and thus two different colorations, two selectable high-pass filters on the detection circuit (80 and 120 Hz), and a BOOM button which activates the famous all buttons in mode (also known as British mode) of the original 1176, altering the performance of the entire circuit for a trademark overdriven tone.

Inspired by the legendary UREI 1176, the 576 FET Compressor is a unit that honors the classic sound of compression that marked a turning point in the history of music. The 1176 is one of the most celebrated and widely used hardware compressors ever made. Rather than offering a sterile digital emulation, Quagliardi Pro Audio presents a true analog recreation, now with improved controls and a convenient 500 Series rack form factor.

In the original 1176, a special mode, often referred to as All Buttons In, or British mode, was possible by pushing in all the ratio buttons at once. This mode is legendary for its distinctive overdriven tone and changes in performance, with the ratio shifting to somewhere between 12:1 and 20:1 and changes in the bias points all over the circuit.

The attack and release times also change and, when combined with compression curve, result in the trademark sound. Now, this mode can be activated with a simple press of a dedicated BOOM button. This mode is particularly useful for creating explosive drum overheads and causes low frequencies to seem more distorted.

• Attack: 20 to 800 µs
• Release: 50 to 100 ms
• Ratio: 20:1 to 4:1
• Meter: up to 21 dB of compression (gain reduction)

Q: 8. Is 85 supposed to be a high CRI?

A: While it is subjective, it is often considered that a CRI (Color Rendering Index) of 85 or higher is recommended as a good CRI measurement for photography usage needs, while those shooting video and broadcast may recommend a CRI of 90 or higher for their usage needs. A higher CRI is recommended when it is necessary or mandatory to display colors accurately, such as with product photography and video (think make-up products, textiles, paints, or fashion, where accurate display of colors is crucial for the brand in question). My recommendation would be to test the light you wish to use and post process your image/video, comparing it to the actual scene to see if the colors that are rendered in your output work is satisfactory for your usage needs. If you like the results, awesome. If not, then I would recommend finding a light fixture with a higher CRI. As 100 is considered the perfect standard (think tungsten lighting or daylight), the higher the CRI you can obtain, the better the light fixture's color rendition.

Q: 9. This softbox comes with the tools to take out the panel of the lights?

A: This needs no tools to assemble

Q: 10. How to keep the Modeling Light on continuously for the Elinchrom ELC Pro HD 500?

A: To turn on the modeling lamp, you would press the button that looks like an image of the sun on the right-hand side of the back of the light fixture. By pressing the button, you can scroll through the options OFF, FREE, which would allow you to to set the modeling lamp output to whichever setting you prefer, and PROP, which would set the output of the modeling lamp proportional to the output of the flash tube. The modeling lamp is designed to shut off momentarily when you trigger the strobe. However, it can be set to also dim temporarily when the flash is triggered, then return to full output power if you have VFC (Visual Flash Confirmation) set on the monolight. Also note that the modeling lamp is designed to switch off automatically at high internal temperatures due to the modeling light's overheat protection function. After cooling off, the halogen modeling lamp will switch back on automatically. Do note that this is a strobe unit, not a continuous light fixture
