ColinHart Posted May 22, 2013 Report Share Posted May 22, 2013 Hey all, I've got an SMa on set here - connecting to UCR-411a. I'm getting levels on the transmitter (so the lav is fine) as well as full RF on the receiver, but no audio on receiver. I've checked all the settings on the receiver and can't find anything wrong. Also sent to a different receiver and had the same problem. Different freq, no change... Any thoughts? Quote Link to comment Share on other sites More sharing options...
Richard Lightstone, CAS Posted May 22, 2013 Report Share Posted May 22, 2013 There is a "standby" mode on the SMa if you do not hold down the buttons for the power on sequence long enough. Try shutting it off and re-power holding down the buttons until after you see the LCD do a count from 1 - 3. From the manual: Power - On The numerals count up from one and the boot sequence begins when the count reaches three. “LECtro” is displayed as the boot sequence begins. If either button is release prior to the screen reaching numeral three, the unit will enter the Standby Mode with no RF output. Standby Mode Pressing the AUDIO and FREQ buttons for about one second places the unit in Standby Mode. In this mode the RF output is turned off so all setup adjustments can be made without interfering with other systems operating in the same location. The screen displays “rf OFF” to remind the user that the unit is not transmitting. Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted May 22, 2013 Report Share Posted May 22, 2013 You're getting a carrier frequency but no audio is being carried. Look to the tx for the source of the problem. Eric Quote Link to comment Share on other sites More sharing options...
Gotham Sound Posted May 22, 2013 Report Share Posted May 22, 2013 Are you sure you are in the correct compatibility mode? It should say CP400 as it powers up. Also, do you get a pilot lock on the 411? Peter Quote Link to comment Share on other sites More sharing options...
ColinHart Posted May 22, 2013 Author Report Share Posted May 22, 2013 Not in RF mute - getting full RF... Tx is the problem, but can't figure out what it could be. Tx audio levels are reading fine, just not getting out. Was working fine 30 minutes previous - stopped while on break. Possibly internal malfunction?

Max Hirtenstein Posted May 22, 2013 Report Share Posted May 22, 2013 I had this happen with an SMQv after sleeping and unsleeping with the Lectro RM app. It needed a firmware update. Turning off and back on fixed the problem but I'm sure you've already tried that. Check your firmware just in case. Quote Link to comment Share on other sites More sharing options...
ColinHart Posted May 22, 2013 Author Report Share Posted May 22, 2013 Peter - Tx booting up as IFB - can you instruct on how to change to 400 mode? Quote Link to comment Share on other sites More sharing options...
atheisticmystic Posted May 22, 2013 Report Share Posted May 22, 2013 From power off position, hold down the arrow up button, and simulatneously hold down the audio and frequency buttons to enter compatibility mode, then arrow to choose 400 mode. you can then briefly hit audio/freq to enter standby mode, or hold down longer to power off.

atheisticmystic Posted May 22, 2013 Report Share Posted May 22, 2013 Sweet! I dont like that panicky feeling I get when I dont know what the problem is on set, so I've synched PDFs of the manuals of every piece of kit I own, rent, and hop to, onto my iPhone. best Quote Link to comment Share on other sites More sharing options...
studiomprd Posted May 22, 2013 Report Share Posted May 22, 2013 " Possibly internal malfunction? " if it isn't operator error. part of being a professional is knowing your gear, --and that often includes "RTFM"-- and troubleshooting...
