jawharp Posted December 14, 2014 Report Share Posted December 14, 2014 Hey Everyone, I've been powering my Cooper CS-106 from my Remote Audio Meon, which only gives out 12 volts. It's been working fine with no issues. I heard that the noise floor of the mixer is greatly reduced when you power it with 18 volts instead of 12 volts. I guess I have 2 questions: Is this true? If so, does anyone know of any reliable product that can convert the voltage from my Meon? All i've been able to find are things made for car batteries like this: http://www.powerstream.com/dc-2171.htm I wasn't sure if the conversion that a unit like this would do would introduce anything nasty power-wise into the mixer or not. Any info would be greatly appreciated. Thanks, Joe Quote Link to comment Share on other sites More sharing options...

Jeff Wexler Posted December 15, 2014 Report Share Posted December 15, 2014 The Remote Audio Juicer is the best way to do this (as Ben mentions above). I think 15 vdc is optimal for the Cooper CS-106 and the noise floor will be at its lowest. I don't believe there is any improvement if you go to 18 vdc. I ran my old Cooper at 13.8 vdc and never really felt there was any noise penalty except when using phantom power on most all inputs (which was generally not the case).

I ran my old Cooper at 13.8 vdc and never really felt there was any noise penalty except when using phantom power on most all inputs (which was generally not the case). A lot of misconceptions about power requirements the Cooper 106. The Cooper CS-106 will deliver it's full published specs with powering voltages as low a 10V, and as high as 27V. It has no change in noise specs within that voltage range. The rumors about "sounding better with 24VDC power" are because of the DC-DC converter that supplies 48V phantom for condenser microphones. A power voltage lower than 12 will cause the phantom voltage to be lower than the 48V phantom spec, which, depending on the microphone, can cause the microphone to have an increased noise floor and have clipping distortion at lower levels than the microphone's spec. Because of voltage drop in the connectors and supply cable, it's safer to have a powering voltage of 13.8 or higher. So, if powering the CS-106 with a nominal 12V battery supply, microphones can become noisier when the battery discharges below 12V. The Remote Audio 15V Juicer outputs 15 volts even the battery voltages down to 10V, so it is ideal to go between the battery supply and the CS-106+1 mixer, and has enough power for the CS-108 with 8 modules. It is so rare that a regulated output of 12V or higher is needed any more, and even less common to need more than one, I believe it's better to add a DC-DC converter cable just for the devices that needed (most will never need this) than to have the added expense and limitations of such an option built into the power supply. gt Quote Link to comment Share on other sites More sharing options...
Malcolm Davies Amps CAS Posted December 15, 2014 Report Share Posted December 15, 2014 On the advice of Coopers I've always fed my 106 with the Remote Audio 24 volt Juicer because of Phantom Power just as Glenn says. Quote Link to comment Share on other sites More sharing options...
