Announcing Stock of our QTB DB-25 to RJ-45 Adapters!
Both genders of ‘Tascam’ D-Sub are available, with 4-40 Captive Screws and Nuts.
AES72-Type 4E follows the wiring method originally used with WBS and QTP development.
Quickly convert a ‘Tascam’ AES-59 D-Sub connector to 2x RJ-45 and Cat5e/6 cabling.
Double PCB Base shrouds all exposed solder connections, eliminating any potential shorts when not used on Racked Components.
Available through Catherine North Electronics – one of the original testing spaces where QTP was used.

We need a Chemist to tell them apart…
Some more Quad Twisted Pair results are in using custom wound transformers found in the renown Ward-Beck Systems IMP series.
We’re finding an insignificant Jitter of less that 200 pico seconds across the spectrum at a clock speed of 192Khz, making QTP perfect for the transmission of digital AES signals up to 192Khz. More to come!
We were lucky enough to have Tristan Miller of Catherine North Audio over for the day to give Quad Twisted Pair an examination. Tristan is an Electronics Technician with a comprehensive background in Electrical systems being a licensed Electrician. Having implemented over a thousand channels of QuadTwisted Pair in his recording studio(s), he has been a great influence of the ideas surrounding implementation and execution. His understanding of Electrical and audio systems is like no other. He came armed with a brand new 1000 foot box of CAT5e Quad Twisted Pair cable to play with. Along with repeating our original tests, some new tests were conducted to compliment our original findings.
We let Tristan drive the Audio Precision 2700 so all tests results were independently confirmed:
