Recording up to 192 tracks on two Protools from a DFC

As noted in a earlier blog the DFC can only arm 48 tracks on each serial port, this two ports are required to arm up 96 tracks on a single machine. In order to record up to 96 tracks on two machines 4 ports are required!

The diagram below shows how this is done and the menu settings required to achieve this at Twickenham Studios.  Note that the menu entries are for the latest version of the X4 and RM- software which were updated this week. Contact me for further details if you need them

Diagram updated to include a second remote, our new DFC-TFT as requested by Twickenham.

Detective work in Paris

Some months ago Daniel (our French representative) complained that every morning his SR-4 crashed when turned on, when reset or restarted it worked without problem. My test unit in the UK however did not suffer from the same problem even with identical software and setup.

A visit to Paris found a bug reading the EEPROM that caused the unit to crash if it could not interface with the EEPROM there remained the problem of why it was not reading the EEPROM.

This week Daniel swapped the chip used to read and write to the EEPROM, this cured the problem, but even when the old chip was put back the problem was gone!

The moral of this story is that if you are having strange problems on old equipment (the SR-4 4 was probably 15 years old) try removing any IC's on sockets and cleaning them!
