Default AES3 distribution

Hi,

To provide balanced aes3 signal to active digital speakers, I need to split the signal from one transmitter to three receivers.

The signal is balanced from a transformer and sent over shielded twisted pair as transmission line.

At the receiver side I need a divider, preferably not another transformer, that keeps the load impedance at 110 Ohm and signal levels at their original sended values.

Is some sort of discrete buffer an idea?

Thanks, Frank

Default No one?

No answers to this?

How about feeding the balanced output (the twisted pairs) into an balanced amplifier. P fet and N fet with the shielding as 0 rail?

Rate the output at 440 ohm (4 times 110 ohm) and connect through 10nF to 4 shielded outputs?

In the video industry we used Video Distribution Amplifier (high bandwidth) to distribute AES-3 signal.
Since most of the patch, cabling and distribution equipment are based on 75 Ohms, that simplify the installation compare to a 110 Ohms installation that necessitate 110 ohms cabling and XLR connector.

OKe,

That's something. Video.

I'll have a look at that. Some similarities could be found.

Perhaps I'll have a look at them XO boys with their fast Fets
