Using Tascam FR-AV2 and ca-11 mics - 1 channel of my preamp recently stopped working and not sure I need a preamp if using 32 bit float and with decent preamps in the recorder. I was looking at the SP-XLRM-MINI-2-PHANTOM but want to be sure it would power the ca-11's properly. I also have the sound pros battery box with 12v battery. Any thoughts or suggestions?
https://soundprofessionals.com/product/SP-XLRM-MINI-2-PHANTOM/"This device is an adaptor for plug-in power mics, which enables the mics to be connected to standard professional microphone preamplifiers or digital recorders with phantom powered XLR inputs. The adapter supplies the appropriate voltage to the plug-in power microphones, and provides a balanced, low impedance output to the microphone preamplifier.
The left and right channels of the adapter operate independently, so phantom power must be supplied to both channels for stereo operation. The adapter requires +9V to +48V phantom power to operate (supply voltage to microphones will be reduced with phantom power supply of less than +12V).
The adapter supplies +5V to each microphone channel."
