I thought I would post this as it's an issue that I have in buying the new Model 950 preamp. Maybe someone knows how the Marantz BUS system works. Hi Gary, I looked over the faxes you sent me. I can see how the Marantz Mono blocks are "daisy chained" together and triggered by a Marantz remote control signal. I am going to email Marantz and ask them if their remote control signal is a digital bit stream, a logic signal (on-off) or a trigger (12V) or something else. Once I get a response, I'll let you know. Just so you know, I do think we can come up with either a wiring solution or black box solution so you can use your Marantz power blocks with our new Model 950. This stuff isn't rocket science. I just don't know how Marantz does their switching (yet!). Best Regards, Tom Thomas E.

I will look at this further this weekend and contact you on Monday. Best Regards, Tom Hi Tom: Many audiophiles use the Marantz MA-500, MA-6100 or the MA-700 monoblocks in their systems. Some use a 12V trigger arrangement for turning them on/off, some just manually press the ON/OFF buttons. I was going to rewrite the Function & Operation info from the Marantz users manual, but I will fax it to you instead. This is basically a convenience feature that puts the monoblocks in a Standby mode, and permits remote ON/OFF functions of the amps when turning on your preamp. If the OUTLAW 950 could perform the same way as the Marantz products, (by providing a RCA IN/OUT type jack) it would be a nice selling feature.
