SMa Connects, No audio

[ColinHart]

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?

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.

You're getting a carrier frequency but no audio is being carried. Look to the tx for the source of the problem.

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?

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?

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.

Peter - Tx booting up as IFB - can you instruct on how to change to 400 mode?

[atheisticmystic]

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.

Got it! Thanks all!

One of those features I never used and actually didn't realize existed!

Cheers for getting and answer within a short period of time using an iPhone and a knowledge collective!!

Thanks Steven.....

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

" 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...
