Here is an old school ElectroVoice 8-Channel Mixer
These were made by Mackie for ElectroVoice. It has super low noise & clean preamps, 2-jack Insert Points (separate Preamp Out and return). Has 3 Aux Sends.
I also added Mono Stacking Inputs and L/R Pre Mono Inputs.
This could make a nice mixdown mixer.
The spec sheet below has the same specs as this listed 7208, the difference being thaat the sahpe was changed and EV added Transformer Balanced Outputs.
