Detailed instructions for use are in the User's Guide.
[. . . ] People who still enjoy listening to their record collections have had to settle for using the often outdated phono preamp stage in their bulky older equipment. The P/HP-100 is compact and up-to-date, using modern state of the art parts and circuitry to provide precise equalization and gain for use with any "line drive" preamplifier, receiver or surround processor. Unpacking the P/PH-100 You should find the following items within the packing carton: The P/PH-100 An 18AWG audiophile-grade AC cord This manual Save your carton and packing inserts for safe transport in case you move or the unit ever requires repair. [. . . ] After making connections, make sure the plugs are inserted securely and the GND terminal is tight to prevent cables or ground wire from becoming loose and disconnected. Note: in rare instances, connecting the ground wire may increase rather than decrease hum. AC Connections Connect the supplied AC cord from the AC inlet of the P/PH-100 to a nearby AC wall outlet or other AC outlet. Your P/PH-100 is intended to be left on at all times and its power consumption is insignificant. You don't need to worry about switching it on and off with the rest of your system.

Setting Gain Levels for Your P/PH-100 The gain of your P/PH-100 is normally set for use with a moving magnet or high output moving coil cartridge. These types of cartridges typically have an output level ranging from 1 to 5 millivolts You can adjust the gain of your P/PH-100 to adequately amplify the very small signal level from moving coil cartridges that range from 0. 15 to 2. 5 millivolts. This gain adjustment is accomplished by moving an internal jumper for each channel. To set the gain for a low output (moving coil) cartridge, insert the jumper into the 2 and 3 position. To set the gain for a high output (moving magnet) cartridge, insert the jumper into the 1 and 2 position. Refer to the specifications for your phono cartridge for optimum gain setting of your P/PH-100.

Rewiring Your P/PH-100 For 220 - 240 Vac Operation Your P/PH-100 may be rewired for operation abroad. This involves changing wires on the primary side of the power transformer. Please refer this voltage conversion to a qualified electronics technician to avoid possible injury or damage to your P/PH-100. For 100-120 Vac operation, the white wire is connected to one side of the AC line and the brown wire is connected to the other; there is no connection to the red wire which is insulated for safety. For 220-240 Vac operation, the white wire is connected to one side of the AC line and the red wire is connected to the other; there is no connection to the brown wire which is insulated for safety.
