Frequently Asked Questions
Can I use condenser microphones with the Nady MM-14FX?
The MM-14FX is designed for use with dynamic microphones. Condenser mics may work but could introduce signal distortion at higher volume levels, and the mixer does not provide phantom power.
Does the mixer run on battery power?
Yes, it operates on a single 9V battery with up to 20 hours of life, or you can use the optional PAD-1 AC/DC adapter for continuous power.
Is this a standalone mixer I can plug speakers into directly?
No, the MM-14FX is not a standalone device. Its single 1/4" line-level output must be connected to an amplifier or powered speaker system.
What does the built-in echo effect do?
The echo DSP simulates room, hall, and stadium reverb decay. You can adjust the decay time and depth using two dedicated control knobs on the front panel.
What type of connectors does this mixer use?
It has four 1/4" mono microphone inputs and one 1/4" unbalanced line-level output.
