The SR-2A-1 Fiber Transmission System (Receiver) from Meridian Technologies incorporates an all-digital encoding technology that supports two unidirectional audio channels over one optical fiber. This model uses multimode fiber. It is well suited for use in intelligent transportation systems, security & surveillance work, access control, among many other applications and settings.

Local indicators provide a visual indication of the status of each audio channel. 3-pin terminal blocks are used for connection of the audio channel interfaces. This series is also compatible with Meridian's SpectraSmart Network management and diagnostic PC-based system.

The DigiSlim product family is available as rack mount cards and modules that can be installed in any of Meridian's desk chassis or in 19" racking frames. This system can be configured in either star (module to rack) or trunking (rack to rack) configurations. These systems can be transformed in to a standalone module by using SR-500/S (standard configuration) or SR-1000/S frames.

Related Questions and Answers

Q: 1. This rescale the inputs? (Like input 4k and scale it to hd?)

A: no this will not scale the input signal

Q: 2. Can it cross convert , i.e. SDI input to HDMI output or vice versa ?

A: Yes it does as the receiver supports simultaneous output of HDMI and SDI.

Q: 3. Can any headphones with a built-in mic work with this system, or is a certain kind of headset required? For instance, can I plug in some old apple EarPods that have a mic on the wire and use that, or does it require something more substantial?

A: It is likely that the FeelWorld W1000S audio output is a TS or TRS jack. Since ear buds with mic have a TRRS plug, you would need a TRRS to TRS adapter. Comica Audio TRRS 3.5mm/Female to TRS/Male Adapter Cable for Camera - 4" BH #COMCPXTRRSTR • MFR #CVM-CPX (TRRS-TRS)

Q: 4. What has to be 1 meter apart to avoid interference when using multiple units? The transmitters, the receivers, or both?

A: Optimal range between transmitter and receiver is between 1 meter and 30 meters with in line of sight indoor

Q: 5. can i power it of a v-mount battery through the barrel connector via d-tap?

A: Yes, of course.

Q: 6. Is it possible to connect this device with Video Switcher Sony MCS 8M

A: Yes it is. The MCS 8M has both SDI and HDMI inputs.

Q: 7. What kind of battery life can I expect from say a NP-550? And is there a chance for interference with wireless mics?

A: Hi Nathan, for a NP-550, battery life is about 2 hours.There's no interference with wireless mics which usually is 600-900 MHz.

Q: 8. can you use multiple sets in close proximity?

A: As long as you keep them about 3 and a half feet apart, you should be able to use multiple sets without interference.

Q: 9. Can Dessqueze the image in an Os Device?

A: While the Hollyland Mars 400 doesn't have desqueezing features, it can send an anamorphic image that can be desqueezed on the receiver end with a functional recorder/monitor or capture device.

Q: 10. What is the latency?

A: The manufacturer rates the latency at "less than 70 ms".
