has anyone tried CA-14 mics without preamp using the mic input on this?  I'm wondering just how stealth I could get with this.  Currently use a CA-9100 amp but that's bulky.  I have an UGLY too but if I could go without I might.

^just need someone to measure the voltage output with a multimeter. I’m guessing it doesn’t put out more than 3V.

^just need someone to measure the voltage output with a multimeter. I’m guessing it doesn’t put out more than 3V.

This is from the Help Guide:

MIC IN (Plug-in-power supported)

Input impedance: approx. 3.9 kΩ
Rated input level: approx. 2.5 mV
Minimum input level: approx. 1 mV

You can also "change the sensitivity level of the external microphone" in the Settings.

That speaks more to the input being overloaded. If I understand correctly the overload at high SPL would occur at the mics if they aren’t provided with adequate voltage.

Thanks!  Looks like the CA-14's really need 9V to not have distortion.

pardon my janky microdot>minijack adapter cable, need to build a real cable



recording test:
4018V > MMP-G > A10 (plug in power)
levels set at 13, handheld in front of monitors

also put both mics in calibrator with 94 and 114 dB test tone earlier on same track, in this case, the levels were peaking around 115 dB at the mics.

i see no evidence of brickwalling, and the noise floor when recording at this level (mics buried in foam in a box tucked away in a quiet place) was  very low, -89dB RMS

https://soundcloud.com/user-760596491/4018v-mmpg-a10

smallest HQ rig ever? A10 is a wee bit smaller than d:vice + the smallest iphone

tested with edirol R07, it worked fine, and while voltage to mics was a shade higher, the noise floor was about 6dB higher than the A10

schoeps, as non-electret condensors, require polarization voltage. all DPAs, small and large, are permanently polarized at several hundred volts

the solutions that provide full 60V to the schoeps caps for polarization voltage are small-ish (naiant ipa, pip squeak, tiny box, and baby nbox in that order of size)

CMRs use a lower voltage source (4-10V) to provide voltage on a third wire to the active mic body which turns it into (reportedly) 40V polarization voltage which runs the cap at a 3-4 dB less sensitivity than a 60V solution like n-bobs, cmc6, kc5, vms02IB, etc.

advantages of CMR:
-uses less power than 60V polarization solutions
-simpler tech, easy to build your own battery box, circuit is literally battery, capacitor,and resistor, less than $20 in parts and good project for entry level hackers
-battery box can be super tiny. baby-bic size if built on 2 3V cr2032 coin cells or a single 6V 4SR44 or 4LR44
-is "official schoeps part" for the snobbish

disadvantage of CMR relative to N-bobs:
-higher cost
-slightly larger (longer) on the active end
-3-4 dB penalty in sensitivity vs 60V polarized caps (nearly moot point for most live taping situations)
-high voltage capsule polarization circuit is probably above the skill level of most DIYers, so youre dropping $200-$500 on a solution to power them (prob a wash on cost of n-bobs vs cmrs in most cases, but something to be aware of)

ive been a schoeps guy for decades. CMRs since 07. However,i cant deny the versatility of the DPAs in form and function so will be trying that for awhile. The fact that the smaller 4061/4099 series is compatible with the same solution that would run full size caps is great. There is not a show i couldnt get 4061s into. with the right caps in right location, there is almost nothing schoeps can do that DPA cant. would be nice if they had vertical diaphragm caps like 4V and 41V that had that ultra smooth off-axis response but hey what can you do? both of those caps come with a significant size penalty as well. DPAs omnis and subcards are right there with the best in the world

smallest youre getting into a schoeps setup with A10 , CR2032 holder fits into the slimmer back area of A10:



youd be potting that cap and resistor into the top portion of that 2x CR2032 holder as well as input/output jacks or cables

DPA 401x w/active shown for reference. about 2/3 the size and weight, and smaller connector on the other end as a 2-wire solution. smallest you can do a pair of CMRs with is either a mini-xlr or TRRS. the factory 3-wire cables on the CMRs are considerably larger than the 2.2mm DPA 2-wire and its really tough to tie 2 cmrs into a TRRS jack without an adapter cable. Hard to see in pic, but DPAs are a mm less in diameter as well, they slide out of my usual schoeps holders

if anybody want to build that tiny bat box i can send you parts for free, i have a few of all of those

Wow... That's impressive. What would be the run time on that? Very cool! A lot of this stuff is over my head. Circuits have never been my strong suit with science.  :(

Can anyone take a screenshot of the iOS app? How accurate are the levels on the app from your experience? I am really contemplating pulling on buying one of these soon.

delivery changed to today.  excited to check it out.  Had a $50 amazon gift card so got it for $179 out of pocket.  Might be selling my R09HR

Good looks, ScottE! Doesn't look too bad. This would be amazing not to have to pull the recorder out anymore and risk of unplugging!
