Ayre Acoustics P-5XE - Manual (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
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.
It is recommended that the
loading not be changed from
47 k when using a
moving-magnet cartridge.
Some moving-coil cartridges will yield better sonic
performance if they are loaded with a lower
impedance. Usually, a lower load impedance results
in a more focused soundstage, with greater image
solidity and less apparent distortion. A higher load
impedance will give a more open sound, with
greater air and life. The final loading value must be
chosen by ear to give the best sound in your
particular system.
Break-In
100 to 500 hours of music
played through the system will
ensure full break-in.
Due to the manufacturing processes used for the
circuit board and capacitors, a break-in period is
necessary for the phono preamplifier to reach its full
performance potential.
