INTRODUCTION AND OPTIONS

The Gold Note PH-1 is a high performance convenient MM & MC phono preamplifier featuring Ultra Linear Power Supply. The design developed for the PH-1 allows matching easily any kind of MM and MC cartridge with a wide option of set up with easy access impedance setting.The PH-1 enables superior audio purity with any audio system featuring an optional external super Power Supply (PSU).

OPERATING CONDITIONS

Once the PH-1 has been correctly wired and positioned on a solid shelf it is ready to play.
The PH-1 has been designed for use in Hi-Fi systems in sheltered locations. It ought therefore to be protected from any eventual variations in temperature and humidity. Avoid to use the unit close to radiators or other strong heat sources, electrical and electronic motors, switched on mobile phones etc.
The location in proximity of other audio components is not theoretically critical, but you should nevertheless pay attention to this. In any case, take care to unplug completely the unit every time you need to move it, or to move the turntable on which it is matched.

PH-1 GAIN AND LOAD

The PH-1 should be purchased set up already as per user needs concerning both Gain and Load. It is anyway possible vary the PH-1 Gain from MM to MC.
It is also possible vary the load impedance on this unit.
Because to do that is necessary to remove the cover of the unit we suggest to contact the local Gold Note® distributor to avoid of warranty invalidity.
Once the cover is removed it is possible to access the DIP SWITCH with 4 Micro-Switches underneath two black Chokes.
The Micro-Switches 1 and 4 can vary the Gain of the unit: setting the Micro- Switches towards the NUMBERS SIDE the PH-1 operates in MM mode; while setting the Micro-Switches towards the ON SIDE the PH-1 operates in MC mode.
The Micro-Switches 2 and 3 are able to vary the load impedance of the unit: with the Micro-Switches towards the NUMBERS SIDE the PH-1 operates with a fix 47KΩ (right for all MM cartridges); with Micro-Switches towards the ON SIDE the PH-1 operates with a 470Ω (default) or changing the resistors (optional) with the unit with a specific load as requested by the user.

The Phono stage Input Interconnect are not plugged.| The “open” input of the Phono Stage may strongly hum. Always connect the Input Interconnect to test the Phono Stage.
The listening volume is very high.| Any phono stage designed to achieve good sonic performances hums a bit when the volume of the amplifier is high. That is normal and strongly noticeable especially without music and with MC gain unit selection.
The tone arm and cartridge are not properly installed| Install them well. Eventually a tone arm cable problem can occur; please check other ways out
The interconnect input and/or output cables are not shielded.| Be sure to always use shielded cables for Phono Stage connections.
PHONO STAGE (THE) DOES NOT WORK WHEN THE PHONO STAGE IS SWITCHED ON| | The AC Phono Stage plug is disconnected from the AC wall plug| Connect it being sure that the AC wall plug works
