Timecode Cables

For use with MovieSlate’s optional Timecode Sync Plugin.

Sources for the required cables.
We and many MovieSlate users have had very good luck with cables from KV Connection. Here is a list of cable options:

iPhone Adapter
This essential little goody does most of the magic: a 3.5mm 4 conductor TRRS Male to 1/4in Microphone Input Jack with built-in -22db Attenuator http://www.kvconnection.com/product-p/km-iphone-mic42-a22.htm
RCA female Jack to 1/4 Mono Phone Plug
BNC to iOS Device Timecode cable
This cable is designed specifically for use with MovieSlate. http://www.kvconnection.com/product-p/km-iphone-bnc-a22.htm

BNC-to-RCA adapters.
We don't have access to equipment with BNC connections to test with, however we believe that a simple BNC-to-RCA adapter will work without problems (provided you get the signal level right, of course). If you have had success with these adapters we'd appreciate a quick note letting us know!

If your equipment uses XLR connectors
To integrate the TC over Sennheiser wireless mic receiver
Folks with RCA-style LINE OUT on their gear
MIC adapters
If your gear is outputting MIC level signal you can use one of KVConnection's MIC adapters without the built-in attenuator: http://www.kvconnection.com/iPhone-Adapters-s/8388.htm
If you live in the United Kingdom
Folks in the UK should check with MLEC (UK) Ltd. They've custom built cables for other MovieSlate users-- including those using Sound Devices recorders.

LEMO Connectors.
Sigh. We don’t have any equipment that uses LEMO connections right now so we can’t guide you to any tested solutions, and we don’t have many leads on LEMO adapters. Here’s what we’ve dug up so far, depending on your variant of LEMO:

3-pin LEMO to XLR Adapter
LEMO to XLR, then use one of the XLR adapters above. http://www.fullcompass.com/product/284060.html
5-pin LEMO to 3p XLR M/F adapter

Wireless Solutions.
Many MovieSlate users have reported success sending and receiving timecode audio wirelessly using transmitters and receivers like those from Comtek. A common workflow is to cable-connect the LTC output from a sound recorder to a wireless transmitter. Then cable-connect a wireless receiver to the iOS device(s) running MovieSlate. Trew Audio often has good deals on used Comtek gear.

Cables for sending timecode.
When sending timecode from MovieSlate, use a standard, unattenuated cable— which you can purchase just about anywhere.

Cables for receiving timecode.
When receiving timecode in MovieSlate, use a custom, attenuated cable as described below. Below are the three variables to take into account for the receiving cable:

Headphone jack at the iOS end of the cable
On the Apple iOS device end of the cable, this jack must be one with four distinct silver bands (as pictured at right). Without those four bands, an iPad/iPhone/iPod touch won't be able to accept audio input.
Denecke has also posted a PDF with the specifications for connecting LTC devices to the iPhone / iPad / iPod Touch.
Jack at other end of the cable
This jack must fit the sound source (such as your TC generator or sound recorder). Your sound source’s manual is a good place to find the type of plug required. Failing that, you could Google for that information.
is actually a way to decrease the volume of the audio that the Apple iOS device receives. Depending upon your sound source, you may not need any attenuation. However, most pro-level sound equipment outputs at LINE level (very loud). All Apple iOS devices receive audio at MIC level (very quiet). If your sound source outputs LINE level audio, then it will easily overpower the poor Apple iOS device. So the audio must be attenuated (quieted). Attenuation may require a bit of trial and error. Not all sound sources (cameras, TC generators, and sound recorders) output audio at the same volume levels. If your sound source has an output volume control, then it is easy to test from MovieSlate’s Settings > Timecode Syncing > Test Headphone Connection. While viewing MovieSlate’s test screen, simply adjust the soure source’s volume until the test screen levels are green and timecode appears in the test screen. Some sound sources don't have a way to control their output volume. In these cases, if you find that the volume is too high for the Apple iOS device, then you'll need to also purchase an attenuating cable.

Gotham Sound Timecode Roll Cable
Gotham Sound’s cable automatically rolls MovieSlate (and logs proper timecode) whenever the Sound Devices 788T rolls and cuts.
