Sennheiser T-power upgrade to 48 volt phantom is here.


The Sennheiser T-Power upgrade to 48 volt phantom website is now on-line. There is now a further means to eliminate T-power barrel adaptors and T-power battery supplies from your kit. Like the Schoeps CMC4 upgrade, our service allows the Sennheiser 416T “family” of RF condenser microphones to operate directly from 48 volt phantom power.

After requesting and receiving an order form from 416Tupgrade.com, include it with your microphone and ship to the address on the form. Turn-around time is typically 5 days. Please visit the site for further details on having your 416T shotgun upgraded to 48V phantom power. Thanks to all the intrepid sound mixers who fearlessly let me take their Sennys “under the knife, ” as we hashed out a robust and reliable conversion process for upgrading T-power shotguns to phantom power.

Happy New Year!  -Pete Verrando

Sennheiser 416T upgrade to 48 volt phantom power

We’ve had many Schoeps CMC4 owners use our 48 volt phantom upgrade service to free themselves from cumbersome T-Power barrels and power supplies. This led to inquiries as to the possibility of upgrading the venerable Sennheiser 416T shotgun to 48V phantom power. After a more than a few willing 416T owners subjected their mics to our electronic musings, we’ve worked out a solid process for converting 416, 415, 815 and 816 T powered Sennheisers to 48 volt phantom. There’s business/website/details to be worked out, and we are looking to get things up and running by September’s end.  As seen in the photo above, the 416T will be branded with a thick aluminum, weather resistant PH48 label to remind users of the  48V phantom upgrade. The cost of the 416T upgrade is still being examined.   As with the Schoeps upgrade, the 416T will perform exactly as it did prior to the upgrade. Sennheiser’s proven RF design- providing immunity from RF or humidity- will remain intact.

Obviously, there will be additional circuitry added to the 416T interior that is not a part of a factory-issued 416.

An important consideration is servicing after the upgrade.  Service issues that arise on upgraded mics must be handled through us. If the issue does not rest with the phantom upgrade, further service may be required by Sennheiser, which we are prepared to facilitate.

Like the Schoeps upgrade, each 416T will be tested prior to, and after upgrading, with before/after test recordings, serial numbers and condition photos kept on file.

If you are reading this, you already know about hassle of using T-Power barrels in location sound work.  They are cumbersome and ill-fitting on the cart or in the bag. Those additional XLRs between mixer, jumpers, boompole and mic invite connection trouble and grounding issues. Accidentally connecting other mics to T-Power inputs invites disaster.  Screen Shot 2015-07-28 at 6.08.29 AM


Consider retiring your T-power barrel adaptors and power supplies.  We are looking at offering a tag-along service to convert those old T-power adaptors into  attenuators…. perhaps very useful when interfacing with the Arri Amira, which has non-standard line level inputs. ( Gawd- not more barrels!)

If you don’t own a 416, now may be the time to scan ebay or your favorite vendors used equipment listings, as 416T’s can be found for very good prices.
