Topic: 12mic-d+ feature requests (if there is ever a 2nd version)

High-Pass Filters are #1. If you want to compete with other remote controlled preamps that have HPF, make it a tri-toggle (3 frequency points)

Having some switchable impedances could be cool.

If you really want to give people some bang for their buck, have the Line Inputs via DSUB on the back which are remote switchable.

Re: 12mic-d+ feature requests (if there is ever a 2nd version)

If there were to be 3 frequency points to offer above and beyond what other companies offer with HPF...
The frequency points should achieve

-Rumble Elimination
-Low Frequency taming
added together or a 3 option
-Low/Low-Mid Frequency "removal", ie high frequency emphasis

Personally, I'd been looking for Remote Control Pre-Amp interface, and HPF was a requirement. Ended up nabbing a Focusrite MP8R for a good used deal from my local dealer.

- Rupert Neve Designs RMP-D8 8-channel Microphone Preamp - HPF@80, 
- Neve 1073OPX 8-channel - HPF@80, Impedance switch, separate Line Inputs+Switch
- Ferdenstein 2 channel Commander (no digital) - HPF@39+82, Impedance Tri-Toggle
- Focusrite MP8r - HPF@65, Impedance 10k½ or 2.4k½

It really doesn't make sense to not include a HPF especially of the pres are going straight to digital.

In other words you want Izotope Ozone embedded into the device.

I'm not sure what you mean, and what Izotope Ozone has anything to do this.

Low rumble elimination using filters has existed since 1930. 2-button/3 option filters have existed pretty much since API was founded, if not before that. If you are stacking filters, you are "stacking" frequency reduction.

This is very fundamental filter practice a high-school student could make from spare electronics, does not require complex software. It would require remote controlled switches, which the 12mic-d already has for other features.

This can be essential for optimum gain before the AD stage, so that rumble/unneeded-low freq aren't taking up headroom.


Here is an example of a 2-button/3-option filter. No fancy software required.
