The WMS-300L Wall Mount User Station w/ A4F Headset Connector from Telex is designed to work with the TW Intercom System. The WMS-300L can operate in an open listening mode with the panel mounted loudspeaker as well as with a headset or a handset. In this mode, almost any headset or handset can be used while the loudspeaker is turned off. This method can be extended by using the loudspeaker for monitoring and the headset or handset for conversation.

The WMS-300L is perfect for permanent installations and includes the following features: a speaker on-off switch, two-channel selection, headphone/loudspeaker volume control, a sidetone control and latching and momentary-action microphone on-off switches.

The WMS-300L wall mount speaker station is designed to work within the TW Intercom System

It fits directly into a standard 4-gang electrical conduit box (2.25" (57.2mm) deep)

The rear section is not enclosed and sets the back-box to provide a housing when installed

This user station is perfect for permanent installations where a wall mounted station can provide an unobtrusive operating position

Most often it is located where the operator can conveniently attend to on-going operations while wearing a headset or listening to the loudspeaker

Typically, the WMS-300L is a very practical user station since it can operate in an open-listening mode with the panel-mounted loudspeaker as well as privately with a headset or a handset. In the open-listening operating mode, with both the loudspeaker and an external microphone turned on, acoustic feedback is suppressed by adjustment of a front panel sidetone (balance) control. This control cancels the originating microphone signal in the local loudspeaker

Most any type of microphone can be used, a hand held push-to-talk microphone, a headset or handset microphone

In the private operating mode, almost any headset or handset can be used while the loudspeaker is turned off. This method can be extended by using the loudspeaker for monitoring and the headset or handset for conversation

Practical operating features include two-channel selection, latching and momentary-action microphone on-off switches, a speaker on-off switch, a sidetone control and a headphone/loudspeaker volume control

Screw terminals counted on the circuit card are provided for user station interconnection to line. A two pair shielded cable such as Belden 8723 or equivalent is recommended since it allows each channel to be carried over a shielded pair, reducing the possibility of crosstalk between channels

Q: 4. Will this lens be compatible with Sony A6000, title says E-Mount full frame, just curious to know what will happen if I attempt to use it on a sony a6000?

A: It will work on the A6300 and the A6000 but your camera has a crop sensor. The field of view will change do to the crop factor of the sensor. Focal Length remains the same. Its like taking a full frame image and cropping to a smaller size. Focal Length remains 50mm. This lens is designed for a full 35mm sized sensor but will be just as happy on your camera as well.

Q: 5. How can I assure that I get a one with the Newest version firmware. A lot of people having a hard time upgrading since it is done through a dock that is apparently not sold in the USA?

A: If this is a Rokinon lens, I can't help you because I returned mine. I have a number Rokinon manual focus lenses, and although the AF lens is outstanding the motor noise while focusing is to prominent for shooting close up video, which is what I needed it for.

Q: 6. for mount Nikon F does focus work well on Nikon z6ii with adapter?

A: Yes this lens would function well with the Nikon Z6II and FTZ adapter.

Q: 7. What is the throw of the focus ring from infinity to minimum focus distance? And does the lens focus linearly without any acceleration?

A: We are not able to measure this and the information is not listed by the manufacturer. We would assume the throw is typical of such entry level auto focus lenses and be no more than 40. No, it would not be linear either. We do not recall any photo or cinema lens that is.

Q: 8. Has anyone used this lens for video? How is the auto focus. We'll be using an a7riii.

A: I used this lens on both the A6500 and the A7iii for video, it makes a clicking sound during video, kind of like the sigma 18-35mm just not as loud. The auto focus is good, I had no issues with it. Overall a great lens.

A: No me. No China. South Korea made this lens.

Q: 10. how to do up the new fireware for this lens?

A: There is a seperate lens “station” that docks the lens and allows to attach to computer for firmware upgrades. The dock needs to be purchased seperately.
