This is super flippin’ cool! I’ve had this for 7 years. It’s not being used for 3 years (don’t worry, will give it a clean and wipe down before sending) but works perfectly. I paid 1k for it in Berlin from a pretty good engineer who prized it and did some bits to it to get it better than it originally was. It’s 70s or 80s if I remember right. Upgraded capacitors and serviced / upgraded – Limiter section sounds like an SSL, can drive it nicely – very rare and very cool. It sounds amazing with everything running through it. I replaced all of the electrolytics in the power supply and the individual channels – – the brand I used was ELNA RS I think… As well, I had to upgrade part of the limiters in my recollection. 9 transformer-balanced mic/line inputs. The line inputs can be switched between balanced or unbalanced. 1 aux/send stereo return transformer balanced. 1 Stereo Master channel out transformer balanced. 1 limiter on the master channel. A beautiful 3 band eq on each channel with the possibility of bypassing. A high pass filter on each channel. Get something stunning today for your analog sounding studio, today!
