Changing Time Code Standard on SR-4/RM-6


When changing the timecode standard enter and exit the setup on the SR-4/RM-6. This will ensure that the RM-6/SR-4 sets the correct timecode standard internally and on the output port.

I will update the RM-6 to correct this in the future.

New Product - TC-5 LTC -Midi-USB Display/Converter

I started this design over a year ago but was external presures delayed the product release. Pre-production units are now available at a target price of Euro 550 with a Real Time Clock option to provide a time of day output will be available for Euro 150.

The TC-5 is a 1/2 rack timecode Reader/Generator that can display and convert  LTC, Midi and USB Midi. One of the main  features is that after setting up the required timecode conversion the display may be used to check at the different timecode inputs without disturbing the timecode output.

The TC-5 also includes a number of test functions, including difference, and reference rate measurement. We are so pleased with this product that we have one on every test bench. No doupt using them on our test benches will result in extra test functions being required!

New P2MMC-USB Software

Last week I spent several days on the sync separator software used in several of our designs. Eventually I had to change the algorithm so that the various factors involved did not interact. The result is a much more stable sync separator for the P2MMC, Euphonix TT002, and the Nuendo SyncStation.

You can download new software for the P2MMC from its product page, I have sent an update to Euphonix (Avid) and will send a update to Nuendo later this week.

AES New York Stand 746

CB Electronics will be sharing a stand with their Japanese agents TAC Systems


CB are showing three new products -

TC-5
LTC-Midi Timecode display/Converter,
A very versatile unit with LTC In/Out, Midi In/Out/Through, USB Midi IN/Out and Virtual Machine.Locking to Crystal, Video or Wordclock with simultaneous conversion between formats

UR422-USB 
A complete redesign of the UR-422, now includes USB, Video Sync input, Timecode Output and Virtual Machine. We have implemented the Odetics extensions to the Sony P2 protocol and plan to add the VDCP protocol to this product.

T-Bar 
We are showing the T-Bar control fitted to the UR422-USB but it may be fitted to any of our keyboard designs and we welcome discussing with customers and agents the optimum keyboard and port configuration.

VCube Crash in Forward Wind

Goldcrest recently reported that the VCube would crash when in forward wind. This was traced to the RM-6 converting the Forward Wind command from the DFC to a forward shuttle command. This is necessary with tape based video machines as there is often no picture in Fast Forward.

To correct change the option in the RM-6 as follows

Setup / Root / Ext/ Menu 097 - Rmt FWD/RWD Cmds to Video Mcn
Set to 0=Normal


The Default is 1=Convert to Shuttle

Dynamic Offset & Edit Offset - What are they? Why do you need them?

Dynamic Offset +/- 4 frames
An offset that is used only in play, unlike the normal offset this is removed in stop. Dynamic Offset is occasionally required to correct for errors in devices (I remember one DAW that required 4 attemps to get the LTC and RS422 in sync). Dynamic offset can also be used to correct for projector/screen delay if the video is on a different device to the audio.

Edit Offset +/- 4 frames
An offset that is only used in playback or record when one or more tracks are armed. A number of digital video devices switch to confidence mode when recording. The timecode switches to be in sync with the playback and is then several frames out of sync with the record. Edit offset is used to correct for this, if not then when you layback the audio it is out of sync..
