In addition to the mic/line inputs, the NX Audio-1601 also has four stereo line inputs, which can be used for connecting instruments, playback devices, or other audio sources. This makes it a versatile mixer that can accommodate a range of performance needs. It also has balanced XLR and 1/4-inch TRS outputs, ensuring a clean and noise-free output signal. The channel faders are smooth and responsive, making it easy to create a balanced mix.
