32 Audios model description

32 Unbalanced Audios over 1 fiber Transmitter and Receiver kit - Single mode / Multimode: F-32A-TxRx ST/PC optical connector, 19" rack mountable

Description

Analog Audio over one fiber Transmitter and Receiver kit helps solve sending unbalanced audio over long distances using Fiber.

We have several diferent models supporting 2, 4, 8,16 and 32 analog XLR Audio.

The audio fiber optic Transmitter, converts analog Audio 20hz to 20Khz fiber optic modulated digital stream so it could be transported over single mode or multimode fiber. (long haul available) - XLR to Optical

The Optical Receiver with XLR outputs converts the optical signal back to its orginal Analog Wave form - Optical to XLR

Offers very low latency 1ms so it's perfect for live events, shows, concerts, auditoriums, etc

The small and compact form factor means it could be used for any applications where copper has a limited distance or noise issues.

Question and Answers

Question:

Do you have a Line Level Audio (analog) over Multimode Fiber in your product line? We need unbalanced audio mostly with terminal block interface. What options do we have for number of channels? The fiber distance is mostly less than a mile

Answer:

So in unidirectional format we have options from 2 Audio all the way up to 32 Audio.

We also have some bidirectional options as well.

The larger issue here is that multimode should be run anywhere near a mile.

Maybe It could work for very short distances.

Maximum I think multimode could carry the signal about 2000ft; but that would be in ideal conditions with almost no loss.

Keep in mind this generally has nothing to do with the units themselves, its the fiber. The same unit that can send a signal about 2000ft on multimode can send the same signal 20km on singlemode.

We do have a 30 day return policy, should you proceed with the purchase, and after installation realize this is not something that can be remedied with hardware, but actually needs to be re-pulled with new fiber.

Question:

What is the diference between Line level and Mic Level on the XLR fiber units

Answer:

The key differences between line level and mic level audio are related to signal strength, impedance, and the types of devices they are typically associated with:

Signal Strength:
- Line Level: Line-level audio signals are relatively strong and have higher voltage levels, typically ranging from around 0.3 to 2 volts. They are pre-amplified to a level suitable for processing or further amplification.
- Mic Level: Mic-level audio signals are much weaker in comparison. They are generated by microphones and have very low voltage levels, often in the range of a few millivolts. Mic-level signals are not pre-amplified and require external preamplification to reach line level.
Impedance:
- Line Level: Line-level signals have a low output impedance, typically ranging from 150 ohms to 600 ohms. This low impedance allows them to be transmitted over cables without significant signal loss.
- Mic Level: Mic-level signals have a high output impedance, usually in the range of 150 ohms to 250 ohms. This higher impedance requires a balanced microphone cable and a preamplifier with a matching input impedance to preserve signal quality.
Devices and Applications:
- Line Level: Line-level signals are commonly used to connect audio sources like CD players, DVD players, synthesizers, and audio interfaces to mixers, amplifiers, and recording devices. They are suitable for transmitting audio over relatively long cable runs.
- Mic Level: Mic-level signals are generated by microphones and are used for capturing audio from sources such as voices or acoustic instruments. These signals are typically sent to microphone preamplifiers to bring them up to line level before further processing or recording.

In summary, the primary difference lies in signal strength and the source of the signal. Line-level signals are strong and pre-amplified, suitable for connecting various audio sources to other equipment. Mic-level signals are very weak and require preamplification before they can be used effectively, typically for capturing audio from microphones. Matching the correct signal level and impedance is essential for ensuring optimal audio quality in professional audio setups.

Question:

I am wonder if somebody can help to cross match or provide an equivalent product for this analog to fiber device.

Item no. A1990031

Transmission system (transceiver) for analog and digital audio signals

Answer:

Yes, we have a whole line of products dedicated to audio over fiber.

https://thorbroadcast.com/products/analog-audio-video

We don't have an exact duplicate, but we do have very similar units that are definitely suitable as a substitute.

There is bidirectional XLR we have

https://thorbroadcast.com/product/xlr-audio-over-fiber-1.html/89

We also have bidirectional analog audio

https://thorbroadcast.com/product/analog-audio-over-fiber-1.html/66

Both of those should be good fits to replace the unit you have sent us.

Question:

If I need 2 channels of balanced audio, how do I wire the connector? Which pin is negative and which is shield?

on a 4 channel unit for 2 channels of balanced audio it’s –

Audio 1 + to pin 1

Audio 1 – to pin 2

Audio 1 Shield to Grd

Audio 2 + to pin 3

Audio 2 – to pin 4

Audio 2 Shield to Grd

Shared Ground Pin for the 2 Shields. Do I have this correct? Just wanting to be sure as my customer will be installing himself.

Balanced is always 3 wires. The shield (pin 1 of an XLR) would go where – to the ground (G) on the terminal block? That would make sense. Positive (pin 2 of an XLR) would go to in 1 of the terminal block, and Negative (pin 3 of an XLR) would go to in 2 of the terminal block.

For channel 2 we would use inputs 3 and 4 with the shield also being attached to the G on the terminal block.

I apologize for not comprehending something that may just be semantics, but in my almost 33 years of installing systems I have spent too many late nights troubleshooting. I will always ask until I have total clarity. I still have a very expensive piece of Thor gear that doesn’t work from 3 years ago because of such a circumstance.

Answer:

Now if you look at the terminal block there are 4 numbers + GND.

So you'll use 1 +2 for the first balanced audio

Then you'll use 3+4 for the second balanced audio

Finally use the GND to ground the unit. Same thing goes on the receiver.

I think looking at the picture makes it much easier to explain than verbalizing.

We do have also Balanced XLR Analog Audio Over fiber
