This is just a simple four channel mixer. The case has wooden sides, an MDF base plate and a wrap around aluminum face plate. The picture on it was cut from an old health textbook. It’s a student taking a hearing test. Great headphones. There are three types of input jacks for each track.
- stereo 1/8″ jacks for plugging in walkmans, cd players, computers, etc. (uses two channels)
- RCA jacks for connecting old home stereo equipment
- 1/4″ jacks for guitar, mic, synth, etc.
