Does anyone own one of these?.
I bought one, but cannot open the darn thing!.
I emailed SP and got this reply:Congratulations on your purchase of The Sound Professionals Slimline battery module. This power supply will enable you to achieve the best possible performance from any microphone that uses 9 volts bias power, also know as ‘plug in power’.
The battery module will protect the internal components from mechanical damage.
The battery module is a self-contained power unit. To access the battery (included and already installed) for replacement, simply remove the xxxx located in the center of the battery unit and remove the cover. The 12-volt battery can now be lifted out and replaced when necessary. The battery will last between 50 and 75 hours of continuous use, depending on the microphones used. It is recommended that you change the battery at least once per year.
I cannot find the xxxx located in the center of the battery unit !
