Welcome to Ayre Your Ayre P-5xe offers a significant advance in the musical performance of high-fidelity equipment. The warmth and immediacy of a live performance are apparent from the first listening. The combination of superb resolution and a natural, relaxed quality will draw you into the music, time and time again.
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.
connectors, there are two choices for making the proper connection: 1) Use custom phono cables with XLR connectors at the phono preamplifier end and the appropriate connector (RCA or DIN, depending on the particular installation) at the turntable end.
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.
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.
Suggested gain settings are: Cartridge Gain Gain to Out Output Setting Bal/Unbal > 3 mV Low 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.
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 ).
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.
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.
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.
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.
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: In this situation extra care must be taken to provide a flexible section to avoid interference with the turntable’s suspension.
Numbers and Specifications Input Impedance 47 k Ω, 1000 Ω , 100 Ω (adjustable) Gain 50 dB, 60 dB, 70 dB – balanced outputs 44 dB, 54 dB, 64 dB – unbalanced outputs (adjustable) Frequency Response RIAA Curve ± 0.
