    Connections and Installation The Ayre P-5xe is easy to connect and use. The following guidelines will ensure that the installation goes smoothly. Location A good location for your phono preamplifier is in a cabinet or on a shelf. Please note that the high-gain circuitry required to amplify the low-level signal from a phono cartridge may be sensitive to the magnetic fields from transformers in other...

  • Page 7 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.

  • Page 8: Controls And

    Controls and Operation The Ayre P-5xe offers the ultimate in flexibility and performance for all types of phono cartridges. Low-noise FET circuitry provides ultra-quiet operation even with the lowest output cartridges. Both gain and loading are easily adjustable to accommodate both moving coil and moving magnet designs.
  • Page 9 Suggested gain settings are: Cartridge Gain Gain to Out Output Setting Bal/Unbal > 3 mV 50/44 dB 1 – 3 mV Med* 60/54 dB < 1 mV High 70/64 dB These settings are guidelines only, and variations are perfectly acceptable. Note that the gain does not depend on which input is selected (balanced or unbalanced), but only on which output is connected.
  • Page 10 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 , 1000 , and 100 . There is a bank of two switches for each channel. When both switches are in the “Up”...

  • Page 12 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”...
  • Page 13 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: Male RCA Shield Male XLR To Phono Preamplifier Turntable Spade Lug Spade Lug Ground Wire This configuration has two separate cables plus a ground wire, and requires balanced cabling with at least two conductors plus a shield.
  • Page 14 turntable, the custom cables must be made flexible to allow proper motion of the suspended sub-chassis. This is normally done by removing a section of the cable’s outer jacket near the turntable. A custom phono cable using a single cable may also be used as shown below: Male RCA Male XLR...
  • Page 15 mini-DIN connector is nearly always on a suspended part of the turntable, and care must be taken to provide a flexible section of the custom phono cable so that the turntable’s suspension can have free motion. It is usually easier to create the required flexibility by using a single cable with four conductors plus a shield, instead of using a separate cable for each channel.
  • Page 16 In the event that a four conductor cable is not available, a pair of cables with at least two conductors each may be used as shown in the following diagram, with the DIN connector shown from the rear (solder) side: Female DIN Shield Male XLR...
