Lectrosonics SMWB coming soon?

Recommended Posts

So today I ran a SMDWB (w/DPA Slim pluged in) with 2 x Ikea Ladda 2450's @ 100mw. 

 

Red light started flashing at 6 hours. 

Complete shutdown at around 7.5 hours.

I just time tested some brand new, hot off the charger Ladda's in an SMQv at 100mw and got 8 hours in one transmitter and 8.5 in another for reference...

3:55 is all I can squeeze out of new Enloop pro, 2450... SMWB, 100mw, and a Sanken COS-11 wired universal...  multiple tests...  Can't believe the Ladda's provide that much better performance... weird..

I used to use Eneloop Pro Black's which were fine/OK but they were starting to give me issues after about 2 years of heavy use.  Was curious as to what else was out there in the nimh battery world and stumbled upon all these articles about the Ikea Ladda batteries.  I just got them last week so TBD on long term reliability but so far I've been very, very impressed.  I bought 40 batteries and 3 Ladda 4 bay chargers for just over $100.  The chargers come with really long cables but are just typical IEC320 C7 ones so I bought three one footers so they can charge easier on my cart.  I start a new show this coming week so I'm looking forward to how well they work... can't beat $6.99 for four 2450mah batteries!  I think the new ikea in Burbank has literally 2000+ packs on hand if any LA folks are looking to try them out.

Something strange going on there, should have equal performance. How old are they?

That Ikea is ridiculous, I've been to smaller cities. The batteries are at the end, by the checkouts, so best to try sneak in the exit to save yourself the hike.

They are brand new with about 3 charge cycles through them...  Multiple tests...

So interestingly, just finished my second test..

 

Same results with the backlight and LED's off. Complete shutdown at around 7.5 hours (happened somewhere between 7h20m and 7h30m). 

 

I guess the backlight and LED power draw is very minimal.

Remember James, I'm discussing a single battery unit test here, not one of my doubles... I'm sure you know that.. I think your surprised by the lack of draw from your switching off of the led lights..

Ah, Gotcha. Your results sound about right then?

Modern LED's pull about 1 to 2  mA for normal brightness. You can run more, but then they hurt your eyes. The back lights for LCD's only pull 3 to 5 mA's. All this to say, turning off the LED's makes very little battery life difference. We only allow them to be turned off to keep them from being seen through clothing.

The first LED's we used on the 30 MHz receivers, back when batteries were made of copper nuggets and dinosaur dung, pulled 25 to 30 mA's. That was too much current to use on a transmitter running from a 9 Volt battery. We thought we had died and gone to heaven when Hewlitt Packard started making LED's that were reasonably bright at 5 mA.

Best Regards,

Larry Fisher

Hello Larry,

 

Will there be an option to have an AES output of your SRc reciever? Thanks

 

Pat

Matt Mayer beat me. That tumbleweed is on the shelf and has been shipping for a little while. Search under AES on the Lectro site. Took me a little while to find it. It's under SRaES which looks like an ES accessory for an SRa.

Thanks Matt,

LEF

YES YES YES!!!!!! THX ;-)

Hi Larry, does the AES plate itself do the conversion from A/D? Or does it somehow grab the digital signal directly from the receiver and just SRC it to 48kHz?

 

Maybe another way to ask this: does using the AES plate actually avoid an A/D conversion or is it just moving the conversion from recorder (or camera) to the receiver plate?

 

Thanks!

Derek
