here’s a layout before i drill and stamp a panel. 8 channels in 3 rack units with a headphone monitoring function. the mic amps are 3 stage neevers. the first stage is two controlled amps in series. so – given a soft instrument requiring a big gain – there’s a mile of fat juicey level with low low background noise and low low distortion.. loads of headroom. tested this neever design against other high end mic amps and reckon this one sounded the best. the most real and clear and lifelike.
