BAB414 Posted October 25, 2016 Report Share Posted October 25, 2016 Hard-wired, my two 50s behave normally. Going into the UH400 transmitter, there is significant gain loss. Using the CMIT with the same wireless setup yields normal results. Any ideas? Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tomer Posted October 25, 2016 Report Share Posted October 25, 2016 Check if you have correct 48v output on your tx Some mikes could work normaly from 12 to 48 with internal dc to dc converor. The 50 need 45v at least Quote Link to comment Share on other sites More sharing options...
RPSharman Posted October 25, 2016 Report Share Posted October 25, 2016 Strange. I find the UH400a and the 50 gives ample gain. I use that all the time. Actually, I sometimes need the pad on the 50 to keep horror movie screams and shouty scenes from hitting the limiter. Once you turn the gain down to 9 o'clock it's either too loud or off. Actually it's the reason I am buying an HMa for the next show. UH400 or 400a? BTW, there is more gain with the 8060 on the same transmitter, so you might just be dealing with the mics being different in terms of output. Do you experience noise if you crank transmitter to compensate? I usually run an ordinary scene at 1 o'clock. Quote Link to comment Share on other sites More sharing options...
jonathan chiles Posted October 25, 2016 Report Share Posted October 25, 2016 I use a 50 with a UH400a regularly and gain on the tx is usually about 2 o'clock if I recall correctly. I think the 50 has a decent output level though not as hot as my MKH8060. Quote Link to comment Share on other sites More sharing options...

Going to try with an HM and report back.Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tomer Posted October 25, 2016 Report Share Posted October 25, 2016 Did you messure it with voltmeter or you tell me where is the switch is ?:) Quote Link to comment Share on other sites More sharing options...
BAB414 Posted October 25, 2016 Author Report Share Posted October 25, 2016 I played with the switch in all three positions.Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tomer Posted October 25, 2016 Report Share Posted October 25, 2016 If your dc to dc converter fucked up on your uh you dont get the 48 v . if you dont have 48 the mkh wont work normaly. The cmit can work from 12 v Thats why you need the voltmeter Quote Link to comment Share on other sites More sharing options...
RPSharman Posted October 25, 2016 Report Share Posted October 25, 2016 It might be worth checking voltage with a meter. I don't know if 400 vs 400a is same as with UM400 vs 400a - there is significant gain difference between those transmitters, so much so that I needed padded cables to use wireless boom.

Tomer Posted October 25, 2016 Report Share Posted October 25, 2016 Same Thevonly other thing may happend you have switch failiur and it stacked on 18 v Try to play with the switch and see if the mike doesnt work at all when you goes to 5v position Quote Link to comment Share on other sites More sharing options...

Tomer Posted October 25, 2016 Report Share Posted October 25, 2016 Place a cable between these 2 and check how much it read under load ) unscrew the xlr plug ) Quote Link to comment Share on other sites More sharing options...
BAB414 Posted October 25, 2016 Author Report Share Posted October 25, 2016 Update: got my hands on another UH400 (41.7 volts) and an HM (46 volts) and had seemingly no issues. I'm dumbfounded.

RPSharman Posted October 25, 2016 Report Share Posted October 25, 2016 These are pretty old items. Might be worth a trip to Lectro, if they still service the 400. Sometimes things just expire :-( Quote Link to comment Share on other sites More sharing options...
Gordonmoore1 Posted October 25, 2016 Report Share Posted October 25, 2016 It may be as simple as the voltage selection switch or the Phantom power switch has failed - make sure they are both in the middle position. Rapid switching may clear some corrosion and restore functionality - exercise the switches a few times to "polish" the internal contacts. If that doesn't clear it up, the UH400 is still supported - you can have JayCee Communications there on the east coats check it or pop it back to the mother-ship here and get it checked out. If your serial number on the UH400 is below 213, the volume knob behaves differently than later units with most of the gain concentrated in the first half of the pot. The last UH400 was built in June of 2004. The difference between the UH400 and the UH400a was a larger microprocessor that allowed us to load the emulation modes. The UH400 just didn't have enough memory. Otherwise, they were the same. Quote Link to comment Share on other sites More sharing options...
BAB414 Posted October 26, 2016 Author Report Share Posted October 26, 2016 Thanks everyone for the advice. I'm just relieved it's not the mics. Definitely the transmitter and since we use the cmit 98% of the time, I'm happy. Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
