Rowland Synergy IIi, Cadence and BPS-1

There are three ways you can operate the bps. There is a power button on the battery unit. You can run the synergy with the power cord on the bps, with the power button off, with the power button on and with the power button on and the power cord pulled off the wall outlet. It sounds alot better with the power cord pulled off. It sound cleaner, more natural, with more detail and greater dynamics. I noticed this with both vinyl and digital. If you are going to listen to your system seriously, this is the only way to go. As a side note, I had to send the charger unit back to Rowlands for repair. It kept on overheating and shutting down. Also, you should check if the battery needs to be changed or not.

Thanks for the further info. I'm excited to try it out. Another quick question - when you were going on exclusive battery power with the unit unplugged from AC, how many hours did it stay adequately charged for listening? When it was plugged in but you were using battery power, did the batteries stay charged while listening, or did the listening sessions surpass its charge (even though plugged in)?

My listening sessions usually last for about a maximum of 3.5 hrs.This is both with the power plug and unplugged. I think Rowland said if you run the bps totally off the battery (ie unpluged), you should be at least be able to play it for 2 hrs or it is time to change the battery. I recently had a technician change all the batteries in my unit and it cost me about $260. My unit had 4 batteries. The single chassis may have different type or number of batteries.

Thanks again for all the info. The BPS-1 should arrive today. I'll charge it today and try to set it up tomorrow. I'll let you know how it goes. Thanks again!

Well the unit arrived. I have the unit hooked up to AC power and have it correctly hooked up to the Synergy IIi and the Cadence phone pre. Both are powered up and running with AC.

With the BPS-1 getting AC power, both the 'full' green light is on and the blue 'AC' light is on. It says in the manual, that when the green light is on it
means that the batteries are at least 50% charged. After about two hours of
charging I pushed the mode button to the battery selection and the unit quickly powered off. I followed the manual instructions and pushed the mode button down for five seconds to reset the supply and power handling, and the unit powered back up on AC. Again after a couple of hours I tried to switch to battery mode and the unit immediately powered off and then went back to AC.

I'm guessed the batteries were fully discharged and needed more time to charge up, but with the green light saying 'full', the manual states that the
batteries are at least 50% charged. Il let it set overnight and charge, but
the same thing will happened again this morning and the battery
mode won't function.

The seller said the unit had new batteries. I'm confused even older batteries won't even hold a few minutes of charge after an all night charge-a-thon.

Thanks in advance for any info or ideas out there....
