Ayre manufactures both adapters and dedicated cables. These high-performance custom designs are available from your authorized Ayre dealer. In addition, termination instructions are available if you wish to reterminate your current cables. Please contact the factory for further details.

Gain and Loading

It is recommended that the loading not be changed from 50 kΩ when using a moving-magnet cartridge.

The gain of the phono stage is set at the factory to 50 dB, which is well suited to most modern phono cartridges. In addition, the gain is adjustable in 10 dB steps from 40 dB to 60 dB, accommodating virtually any cartridge made.

Recommended gain settings are as follows:

Cartridge Output	Phono Gain		Gain Resistor
Less than 1.0 mV . .	. . . 60 dB . . . . . . . 10Ω
1.0 mV to 3.0 mV .	. . .	50 dB . . . . . . . 75Ω
Greater than 3.0 mV	. . .	40 dB . . . . . . 249Ω

These are guidelines only. Variations from these settings are perfectly acceptable.

The default cartridge load is 50 kΩ , which is suitable for almost all cartridges. However, many moving-coil cartridges yield better 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 value must be chosen by ear to give the best sound in your particular system.
