A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Ayre Acoustics P-5XE, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

    Outputs The Ayre P-5xe offers one pair of balanced (XLR) outputs and one pair of unbalanced (RCA) outputs. Although both sets of outputs are always active regardless of which input (balanced or unbalanced) is used, it is normally recommended to only use one set of outputs at a time. Note that the level of the unbalanced outputs will be 6 dB lower t[...]

    Setting the Loading Cartridge loading can be adjusted with switches on the rear panel. The loading options built in to the Ayre P-5xe are 47 k Ω , 1000 Ω , and 100 Ω . There is a bank of two switches for each channel. When both switches are in the “Up” position the cartridge load is 47 k Ω , which is suitable for almost all cartridges. [...]

    Optimization and Customization Technically oriented users may wish to explore additional customization options that are available. Custom Loading Resistors When using custom loading resistors, leave the loading switches in the “Up” position (47 k Ω ). Should additional loading values be desired, custom loading resistors are also easily accomm[...]

    When using an unbalanced (RCA) connection to the turntable, solder the custom loading resistors between pins 2 and 3 of the additional male XLR connectors. These additional connectors are then inserted into the otherwise unused balanced inputs of the P-5xe. Custom Phono Cables As noted in the “Connections and Installation” section, a balanced c[...]

    Turntables with RCA Connectors One common turntable configuration has two RCA jacks plus a ground post. Following is a schematic diagram of a suitable custom cable: This configuration has two separate cables plus a ground wire, and requires balanced cabling with at least two conductors plus a shield. If the cabling has a third conductor (in additio[...]
