USER MANUAL GOLDMUND PH3 Phono Preamplifier... - Page 2 The guiding principle at Goldmund is to produce a precise sound with the latest possible loss of quality through the different stages. Goldmund will never adopt a technology before it is sufficiently developed to satisfy the high quality standards we set.
- Page 3 Only careful installation and use can provide the satisfaction you are expecting. The installation instructions must be carried out in full and the mentioned precautions taken to get the expected result and to avoid impairing performance. User manual – Goldmund PH3 Phono Preamplifier...
- Page 4 CHOICE OF PHONO PREAMPLIFIER LOCATION AND COOLING The Goldmund PH3 phono preamplifier does not generate a significant amount of heat. The performance of the phono preamplifier is however directly related to its thermal stability. The PH3 must therefore be located to allow adequate cooling of the heatsink without over- ventilation.

- Page 6 Note: Both inputs can be connected simultaneously if no hum is generated. In that case, the front panel selecting the inputs acts a source selector between the two cartridges or tone- arms. Plug the output interconnects from the RCA female sockets (labeled “output”) to the preamplifier. User manual – Goldmund PH3 Phono Preamplifier...
- Page 7 After this delay, the output of the preamplifier is connected to the output connectors. Note: The GOLDMUND PH3 phono preamplifier should remain connected at all times. If the power cord is accidentally disconnected, a special safety circuit switches the preamp to muting, to avoid any disturbance to reach the power amplifier and the speakers, even in case of a power failure in the building.
