Nady MM141 4-Channel Mono Mini Mixer Portable

The Nady MM-141 is a no-frills 4-channel mono mini mixer built for situations where portability and simplicity matter more than feature depth. With four 1/4-inch unbalanced inputs, each equipped with its own volume knob, plus a master volume control, it lets you quickly combine up to four mono audio sources into a single output. The entire unit runs on a 9V battery, making it a practical choice for field recording setups, small rehearsal spaces, busking rigs, or any scenario where AC power is unavailable or inconvenient.

The trade-off for this simplicity is a deliberate one: there is no EQ, no effects processing, no stereo imaging, and no balanced or XLR connectivity. The MM-141 is purely a signal combiner with level control. For musicians combining multiple instrument outputs into a single amp input, audio technicians needing a quick submix, or presenters consolidating sources for a powered speaker, it does exactly what it promises without unnecessary complexity. An optional AC adapter is available for permanent installations where battery replacement would be impractical.
