To ensure proper functioning of the module, a well built supply is needed. This power supply has all the functions implemented to make a perfect match with the UcD700.

DC-protection. Switches off the secondary power supply voltages until the mains is disconnected. AC-detect for a pop-free start/stop control. When the mains is disconnected the UcD700 immediately switches off avoiding pops. Protect +12V GND -12V Ground loops +90V GND -90V Power Supply Fig 1. UcD700 Power Supply connections/dimensions +15V Vdr To avoid ground loops there are two possible grounding settings. The default setting is for mono applications (Fig 3) and for stereo applications (two UcD700’s connected to one supply) user must remove two solder links (bottom of PCB) and make a solder link (bottom of PCB) like shown in Fig 4. WARNING! Before changing settings disconnect the amplifier from the mains and wait at least 5 minutes before soldering. Check the supply voltages (<45Vdc between Vee and Vcc) with a voltmeter if possible.
