AA1723 Frequently Asked Questions

Is there a maximum length for a Toslink cable, as I need a 20m cable from dvd player to amp.?
Yes, to save cost manufacture build down to a minimum standard. Your only option is to buy a cable and see if it works, unfortunately we do not stock 20m Toslink cables. We have found that 10m tends to be the upper limit.

To ensure the maximum chance of it working remember

Obtain the largest diameter optical cable
Ensure that there are no "tight" bends in the fibre optic (i.e. do not bend it into the corners of your room!)

I am looking at the Toslink to Toslink connectors. Can you tell me what the (2.2mm OD) (6mm OD) mean. What is the difference?
The difference is in the diameter of the fibre cable. The larger the diameter the less attenuation (i.e. signal will travel further). But you can not bend a larger diameter cable as tightly as s smaller diameter cable.

Is wiring your dvd player to your AV amp using optic leads better then using high quality phono leads. If so please can you explain the advantages?
These optical links have a number of advantages compared to phono connectors

Signal is immune from electrical interference
No cross talk between audio signals
Digital signal is preserved to amplifier

The only disadvantage could be the digital-to-analogue convertor in the amplifier.
