RA16SD Tech Notes

Running a Medusa PreAmp off an external battery


Product: RA4PA, RA16PA, RA16SD
Version: All
Date Added: 2007-07-12


Customers looking for extra battery life for their Medusa PreAmp can purchase the PZ-BAT external battery pack from TDT.

Alternatively, off the shelf 6V batteries, such as a motorcycle battery or a battery for use with emergency lighting, can be adapted for this purpose. A battery/charger that has worked can be found here:"


This battery has a capacity of 12 Amp-hr, which should power an RA16PA for about160 hours.

This type of battery can be connected to the voltage inputs of the PreAmp using a Digi-Key connector (part number SC1051-ND). The connector will have to be wired to utilize the desired battery.


The SC1051-ND connector is center negative. Inverting the connection will damage the PreAmp.
