2-Channel vs 4-Channel Mixer Specs
channel count
The Numark M2 is a 2-channel scratch mixer. It handles two audio sources simultaneously. This setup is standard for basic turntable or CDJ pairs. The W In-mix TC-4 offers four distinct input channels. You can connect twice as many sources at once. This allows for more complex live arrangements or multi-source mixing. If you need to blend four separate inputs without external switching, the W In-mix provides the physical capacity. The Numark limits you to two main decks.
equalizer control
Both units provide 3-band equalizers for each individual channel. The Numark M2 sticks to this standard per-channel control. The W In-mix TC-4 adds a 7-band stereo graphic equalizer for the master output. This master EQ lets you shape the overall room sound or correct frequency issues globally. It offers more surgical precision for the final mix. The Numark lacks this global graphic EQ layer. If you need detailed master channel tuning, the W In-mix gives you more tools.
connectivity options
The Numark M2 relies on wired connections. It includes RCA phono/line inputs and RCA outputs. It also has a 1/4-inch mic input and headphone jack. There is no wireless capability listed.

The Numark lacks effects and phantom power. If you need mic preamps or sound effects, the W In-mix is superior. If you only need scratch controls, the Numark is specialized.
form factor
The Numark M2 is ultra-portable. It weighs 6 pounds and measures 13.5 by 14.5 inches. It includes rackmount facilities for easy transport. The W In-mix TC-4 is a tabletop unit.
