Thank you for viewing. This is a compact mixer from neu. It has a built-in AC power supply and operates with only a power cable. It's compact and lightweight, with vertical faders for each channel. In addition to input gain and pan, it features a 3-band equalizer for sound quality correction and a delay for creating reverb effects, allowing for high-quality mixing as desired. It also has necessary functions such as AUX SEND for monitor output, TAPE IN/OUT for input/output with external recording/playback devices like audio players and recorders, and a headphone output. It has a built-in +48V phantom power supply, supporting high-quality recording with condenser microphones that require power. It's ideal for locations that require a compact mixer, such as shops, as well as for recording at home or in a studio. ◆ Features ・4CH mixer in total: 2 mono channels, 1 stereo channel ・Built-in +48V phantom power ・Gain, pan, and 3-band EQ on each input ・Effect send/return, AUX send output ・Built-in digital delay It's a beautiful item with little use, having been used only a few times.
