• The EW-DX system utilizes an equidistant tuning grid that equally spaces 3200 frequencies across its wide 80 MHz bandwidth to prevent disruptive intermodulation issues that occur when multiple transmitters operate in confined spaces.
• The system can be expanded with multiple transmitters and receivers to offer up to 134 channels in equidistant tuning grid mode, and up to 269 channels in Link Density mode.
• The EW-DX SK is backward-compatible with EW-D receivers.

• The sweat-resistant, subminiature MKE 2 omnidirectional lavalier mic offers a pristine, broadcast-quality sound and is easy to conceal.
• The unobtrusive ME 2 omnidirectional lavalier mic provides a forgiving pickup pattern that captures sound equally well in every direction.
• The ME 4 cardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
• The ME 3 cardioid headset mic provides enhanced speech clarity for lectures and presentations.
• The CI 1 instrument cable lets you connect the bodypack transmitter to a guitar, bass, or keyboard.

Related Questions and Answers

Q: 1. How to get line-level into the AVX? When I use the CL440 or CL2 cable it is mic-level and so very distorted.

A: What you will have to do is. Go into the menu on the transmitter to Sensitivity. It will probably be set -6dB drop it down till about -12dB and see if that does it. Either way you have to reduce the sensitivity and then compensate from the receiver by bringing up the AF out. AF out will be the output level to the camera.

Q: 2. on the input it says line/mic. What kind of cable is the used for line input?

A: That would be the Sennheiser CL-2 cable (B&H # SECL2 ). https://www.bhphotovideo.com/c/product/217589-REG/Sennheiser_CL2_CL_2_Transmitter_Line_Cable.html

Q: 3. How much difference does 30mw vs 50 mw have on reliability, reception and range?

A: Every milliwat may count when tolerances are very close. It sometimes can be a game of inches.

Q: 4. Hi there. Will this unit supply 48 V phantom power to a shotgun mic? Cheers

A: Hi Marc - the SK 100 G4 bodypack transmitter doesn’t supply 48V phantom power, however, the SKP 500 G4 plug-on transmitter does. If you’re working with a shotgun microphone that can be powered via battery or phantom powers - such as the MKE 600 - you could also use the SKP 100 G4 plug-on transmitter as a more cost effective solution. Alternately, a CM 1 XLR Female to 3.5mm locking connector adapter cable can also be used with the MKE 600 to connect it to a bodypack transmitter. For +48V phantom power, you’ll want to be looking at the 500 Series (EW 500 G4 BOOM, EW 500 G4 FILM or SKP 500 G4).

Q: 5. I want to mic a maximum of 12 performers with EW D. Do I need a variety of frequency bands? (4 each to cover 470 -600Mhz?)

A: You will be able to have a maximum of 90 transmitters per band, so if there is not significant interference in your area it should be alright to keep the same band for all systems.

Q: 7. Does the transmitter provide phantom power for mics like MKH 8050?
