Re: Mic'ing 2 instruments to a single amp
Though the main mic input’s phantom power circuit then has to power two mics and the mini mixer. Whilst a lot probably would, there will be some that can’t.
Reliably fallible.
Re: Mic'ing 2 instruments to a single amp
Quite so.
The combiner draws 2-4mA, leaving at most 3 or 4mA per connected mic. That's enough for many, but certainly not all. This combiner is designed for AT's Unipoint conference mics, and the ones I checked pull only 2mA.

Then a transformer combiner would be fine!

Re: Mic'ing 2 instruments to a single amp
That may be so if the source levels are similar, but the balance control will be essential for the particular application I have in mind
Two M201s feeding a preamp in order to route around a pedal board - one will have the equivalent of a trumpet, the other rustling leaves - yes, I know, it’ll still be a challenge!

The balance control only has a +/-6dB range...

Re: Mic'ing 2 instruments to a single amp
?
Like many balance controls, the centre position gives 6dB of attenuation of both signals in the centre position to maintain a rough overall unity gain throughout the balance control travel (assuming both input signal levels were the same). The tech info states a maximum attenuation of 33dB (but no boost), so it would seem you can't totally silence one channel.
Reliably fallible.
Re: Mic'ing 2 instruments to a single amp
Apologies, I misread / misunderstood the brochure.
You're quite right, it looks like the balance range is about 27dB.
