The elysia xfilter Mastering Edition 4-Band Analog Stereo Equalizer is a powerful, true stereo linked EQ designed for the exacting standards and rigors of mastering and is capable of delivering versatile, Class-A performance. 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 Mastering Edition is engineered to deliver maximum creative potential and high-quality sound via its handcrafted, discrete circuitry and intuitive design.

The xfilter Mastering Edition sports precise ±5 dB control over all four bands, and Q factor can be switched between narrow and wide for ultraprecise 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. The balanced output stage has been reconfigured for mastering purposes and provides up to +27 dBu of headroom. Flexibility, excellent sound quality, and a robust range of filtering options make the xfilter Mastering Edition a great choice for anyone looking for a pro-quality mastering EQ without the premium price tag.

Unlike most equalizers, the xfilter Mastering Edition 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 Mastering Edition 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 Mastering Edition 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 Mastering Edition 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 Mastering Edition 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. Do you need a ham radio license or something different?

A: The Motorola MOTOTRBO CP200d Portable 5W 16-Channel Analog/Digital 2-Way Radio requires a license from the FCC for legal use. For business applications, a "Business Radio Service" license is required. For private use, a "GMRS" (general mobile radio service) license is required.

Q: 2. In his instructional video, Peter Zelinka recommends removing any "plates" from telephoto lenses and attaching the lens using the lens collar foot only. Any thoughts on this?

A: In principle it is a good choice. Using the lens collar allows addition adjustments to the lens.

Q: 3. 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: 4. Samson SR350 Over-Ear Stereo Headphones Kit (Special Edition Blue, 3-Pack) BH #SASR350DB3K (B&H Kit) Do they get individual box packings? Or three in one box?

A: Each headset will come in its own box.

Q: 5. 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: 6. Does this do multitrack recording?

A: It is designed for stereo mixing and recording only.

Q: 7. does it have a microphone?

A: This Headphones doesn't have Microphone build in.

Q: 8. will this one will work with nexstar 60SLT ?

A: No, the Celestron NexStar+ EQ Hand Controller is only for EQ mounts, and can only be used with the Celestron NexStar 60 SLT 2.4"/60mm Refractor Telescope Kit if one flashes the firmware for the AZ mounts. A better option is to get the Celestron NexStar+ AZ Hand Controller, BH #CENSHCUA (https://bhpho.to/3K5P93F).

Q: 9. Can I use the Motorola CLS 1410 to communicate with these?

A: Radios operating on UHF channels such as the Motorola CLS1410 will not communicate with radios operating on VHF channels such as the Motorola MOTOTRBO CP200d Portable 5W 16-Channel Analog/Digital 2-Way Radio (VHF Band). If the UHF version of the CP200d is selected (BH #MOCP200DU) there is a possibility that the two radios could communicate if programmed to the same frequency channels.

Q: 10. Does this unit include a charger for the battery?

A: Yes, there is a battery charger included with the Motorola MOTOTRBO CP200d Portable 4W 16-Channel Analog 2-Way Radio.
