DPA 6060 or 6061 into Lectrosonics

[Mark]

Hi all. 
anyone using DPA 6060 or 6061 into Lectrosonics smqv or ssm?

thoughts?

Around where are you setting tx gain?

cheers

[Derek H]

Try 25-30 on a 6061. 15-20 for a 6060. 

[Mark]

Thanks Derek.

obviously it is different fo different voices.

trying to get some feedback before a purchase as there may not be the opportunity to test before then.

As a happy DPA user for many years, (4060/4061), just trying to get some real world feedback.

[LarryF]

IMHO, I think the 4060 is the better choice. On loud signals, you can use "0" with no transmitter preamp problems. Make sure whoever builds the connector, uses the Lectrosonics recommended 1k resistor. Ignore the DPA recommendation of no resistor on the 4061. Set the gain according to the transmitter manual.

Best Regards,

Larry Fisher

I would say, the 60xx are essentially the same in terms of sound and settings, so if you are used to the 40xx, you'll probably won't need to make any changes. The main difference is they are smaller in size. I use both 4061and 6061, and to me they are interchangeable.

Thanks Larry and Johnny.

Microdot to Ta5f would be a DPA adapter.

all input most appreciated.

cheers

[Mark]

Just reread your reply properly Larry.

1k resistor it is!

[Derek H]

I thought the recommendation for DPA’s with Lectro was a 3-4k resistor?

[Matthew Steel]

I see 4k on my older printed copy of the wiring recommendations, with a note that it can be 3k-4k.

I also have a note that the DPA DAD3056 microdot adapter uses a 3.9k resistor.

 

I think mine are wired with 3.3k because I had them on hand from olden times when I followed the DAD6012 adapter schematic.

[LarryF]

Any value from 2K to 4K is just fine with the lower value giving 6 dB more output. 3.9k is a standard resistor value.

Thanks Larry. Does the choice of resistor value have any influence on the capsules max SPL handling? For example if I put a 2k with a 4061 do I lose 6dB of SPL handling or does it only mean I need less gain on the transmitter to reach the same output?

 

The question behind the question is could I wire my 4061s with 2k and 4060s with 4k with the goal of balancing the gain needed on the transmitter to be similar for each mic. It’s a common problem in the field that they get mixed up and suddenly I have an actor on a 4060 gained for a 61 and it overloads for a take or two before we figure it out and adjust.

Hello
Why do so many colleagues use the DPA 4061 for dialogue recordings? I compared it, and the 4060 has significantly less self-noise, and with speech, I never reach the max SPL.

You can certainly do that. The transmitter has enough gain range to handle a minor 6dB change in level. As you asked, you just need less gain in the transmitter. You won't lose 6 dB of SPL handling in the mic since the servo circuit in the transmitter will compensate for the decreased or increased current draw of the mic as you vary the resistance.

I think it’s because of our fear of unexpected overloads. Actors have been known to suddenly change their performance level without warning. 
 

Though I think it’s a fair point though and the 4060, especially the core versions have just about as much headroom as most traditional lavs if not more. 
 

I think generally though we like knowing the capsule can handle anything the performer could throw at it and prefer to gain up the quiet stuff if needed. Also Lectro’s Smart Noise Reduction has many of us never hearing the added noise floor.

Thanks Larry, I might experiment with this.

Is there a simple wiring for a 6060? All I see is this one, which says 3k - 4k.

 

I have had clipping on yelling with both 6060s and 6061, in fact it seems there's hardly any difference between the two. But that could be because the resistors are different!

All my 4061 have a 1.8k resistor and al my 4060 have 3.3k resistor, all work perfectly gain wise never had a clip on 4061 with that 1.8k even when used in racing cars etc.. 

[Derek H]

Thanks, and can I ask what gain setting do you typically end up using with each?

On Lectro smdb  4061 is about 26 gain.. And 4060 is about 18- 20 gain

[Derek H]

That’s about what I do now with everything wired with 3.9k.

[Derek H]

I don’t think so. I think a resistor is a requirement. Larry would know better than I thought. 

[LarryF]

Yes, the resistor is a requirement. Newer digital Lectro units have the resistor in the transmitter and switch it into circuit when DPA  is menu selected.

Thank you! I appreciate the info.
