Atlasied Tsd-zdc 4x4 Impedance Divider Combiner
- Product Code: eq175485
-
The AtlasIED TSD-ZDC 4x4 Impedance Divider Combineris a universal impedance divider/combiner for passively summing or splitting mic or line level signals. Features include four balanced 10K and four balanced 150Ω inputs and outputs that may be passively split or combined in any arrangement.
Typical applications for the TSD-ZDC include passive summation of multiple 150Ω mics or stereo 10K sources and passive splitting of 150Ω or 10K input sources to multiple outputs. To ease contractor use and installation the TSD-ZDC includes individual ground connectors for each input/output. The unit's compact footprint allows standalone mounting or an optional rack mount adapter may be used to facilitate up to 4 TSD devices.

Related Questions and Answers
Q: 1. When you use this as a combiner (for example, use two microphones and mix the audio signals from the microphones in this device) can you still split the output signal into two? I just need to use two mics but amplify the sound in a monitor as well as record it in my audio recording device.
A: Thank you for your email. Once the signal is combined you are unable to split the signal output of the combiner.
Q: 2. Is this really a transformer, or a simple adapter. If a transformer, what is the ratio?
A: It is a transformer designed to work with DSLRs and consumer grade camcorders. The impedance match specs are not available.
Q: 3. can you recommend a longer cable to work with this adapter?
A: Since this is an impedance matching transformer, it would be recommended to use an XLR cable of the length of your choice to connect to the XLR female side in order to extend.
Q: 4. Can this be used to split one phantom-powered mic into 2 tracks on an audio recorder for a low safety track?
A: Yes, you can use the ART SPLITCom Pro Microphone Splitter/Combiner to split the power on a phantom powered mic.
Q: 5. Is there a way to add phantom power device to use my audio Technica shotgun mic that I used to use with a DAT recorder that had phantom power, but now all my cables do not work with 1/8in cameras or devices. Thanks for any advice?
A: A device such as the Denecke PS-1A Portable Single Channel 48V Phantom Power Supply (BH #DEPS1A) could be used in between a phantom-powered shotgun microphone and the Kopul LMT100 Low to High Impedance Matching Transformer for proper connection to 3.5mm camera inputs: https://bhpho.to/3rPrNa4
Q: 6. I have a shotgun mic without phantom power so how can I use these cables?
A: A shotgun microphone that powers itself/does not require phantom power is a great candidate for connection of the microphone to a 3.5mm input such as those found on DSLR cameras using the Kopul LMT100 Low to High Impedance Matching Transformer.
Q: 7. How to connect to laptop for USB power?
A: I am not aware of an option to provide this with USB power. This comes with a power supply for use with wall plugin power only.
Q: 8. I got this cable with the Senn 600 and when plugged into my Canon 80D it only registers on the LEFT channel, is this because of the cable or because the Senn is a mono mic? Do I need to do something else to have it record bother left and right channels, there are no options on the 80D for that, thanks.
A: The LMT-100 is specifically designed for connection of a mono mic to a camera. Audio should be present on both sides using this cable and should have no issues with the Sennheiser or similar mics. We do however generally recommend the Sennheiser brand cable (KA-600). https://bhpho.to/2gPQ0Wn Please contact a Representative here for additional assistance at 800-606-6969.
Q: 9. can you recommend a longer cable to work with this adapter?
A: For a longer cable run, you may use a standard XLR cable. You may consider B&H # KOM4025 for a 25' extension.
Q: 10. if i connect my 100 ohm mic to my dslr 3.5 jack using this transformer, will the recorded sound still have around 100 ohm impedance?
A: This is an impedance matching transformer. It will convert your 100 ohm mic to approx. 2000-3000 ohms to match your cameras mic input. Recorded audio is not measured in impedance, but decibels.
