The elysia xfilter Dual-Channel 4-Band Analog Stereo Equalizer is a powerful, true stereo linked EQ capable of providing professional and advanced home studio engineers with versatile, Class-A performance in a package that far surpasses its price point. With a precise stereo image based on computer-selected 41-step pots and the heart and soul of elysia's flagship museq EQ processor, the xfilter is engineered to deliver maximum creative potential and high-quality sound via its handcrafted, discrete circuitry and intuitive design.

The xfilter sports special low tolerance capacitors that ensure every layer of each pot performs to exacting standards across both channels, and Q factor can be switched between narrow and wide for ultra-precise filtering. An additional passive high-band EQ gives you the ability to polish your signals top end with the push of a button, and the true stereo link enables quick and easy equalization by allowing processing of both channels with just a single set of controllers. Flexibility, excellent sound quality, and a robust range of filtering options make the xfilter a great choice for anyone looking for pro quality without a premium price tag.

Unlike most equalizers, the xfilter not only possess dual-channels but full stereo link as well, allowing you to process both of its channels with just one set of controllers. You can either process a single signal in mono operation, or use both inputs for left and right stereo operation, with your choice of what channel becomes which end of the stereo field. No more tedious fiddling around with knobs to try and get the EQ channels to match each other; the xfilter does this automatically and the computer-selected dual and quad layer pots, as well as special low tolerance FKS-type film capacitors, ensure identical performance for both channels, regardless of settings.

The outer bands of the xfilter provide a great amount of flexibility by enabling the ability to switch between shelving or peak cut filters. In standard mode, the filters function as sweet sounding high- and low-shelf filters for quickly and efficiently tailoring the fundamentals and airiness of your tracks. You can also independently switch these to become high- and low-cut filters with 12 dB per octave, with an additional resonance peak at the knee frequency. The resulting filter curves can provide a clean and punchy character by cutting the low frequencies or a stretching of the bass range by causing a longer post-oscillation time. In the the high range, the resonance filter can put an accent on a selected frequency without boosting the whole spectrum, avoiding harshness or an unwanted shift of the whole signal into the treble.

In addition to it's four flexible active bands, the xfilter features a switchable fixed LC filter for polishing the high-frequency range. This filter mainly consists of a single capacitor and coil per channel, but unlike traditional shelving designs, it has a slight resonance peak at 12 kHz and starts to fall off at 17 kHz. In this way, the coil's saturation-like storage effect focuses on the peak without pushing the whole high-frequency spectrum. The use of shielded inductors eliminates unwanted hum and noise that would otherwise plague the highly charged coils.

The xfilter allows you to switch between two Q factors for each of the three parametric bands: Wide (Q 0.5) and Narrow (Q 1.0). These Q factors are based upon the proportional Q principle and provide very musical processing.

Q: 1. What is the communication distance between two Motorola CP200d?

A: The Motorola CP200D Portable 4W 16-Channel Analog/Digital Two-Way Radios can communicate indoors within a range of up to approximately 350,000 square feet or within 30 floors. When used outdoors, they can communicate within approximately 1 to 3 miles.

Q: 2. can this also be used to stop the will this stop the focus ring from moving? or does it only work in controlling the zoom ring?

A: This is meant to hold down the zoom ring, Whether it can hold the focus ring of your lens depends on the exactly lens you're using and whether or not the focus mode is set to manual.

Q: 3. How do I measure the size of my focus ring ? I own a Nikon 35mm 1/1.4, Nikon 24-120 and a Nikon 200-500 5.6 ?

A: You would go by the diameter of your lens. This particular Lens Band fits lenses with a diameter from 2.6-4.3".

A: This product does not have a screen.

Q: 7. Do you need an FCC license to operate these CP200s?

A: Yes, an FCC is required to operate the Motorola MOTOTRBO CP200d Portable 4W 16-Channel Analog 2-Way Radio.

Q: 8. I have a 50mm Sony 1.8 lens so I'm not worried about the size, however I was more wondering if this could be added just to help with getting a grip of the manual focus ring. Is it thin enough so it could solely lie on the focus ring? It would be nice to use when gloves are involved.

A: The LENSband Lens Band MINI (Black) can fit on the Sony FE 50mm f/1.8 Lens. It is thinner than the focusing ring on the lens and will not cover any other part of the lens.

Q: 9. Does it come with Toslink to Toslink Optical Audio Cable?

A: According to the manufacturer's item details there is a 3-foot optical cable included.
