Ayre K-5x

Commentary

A preamplifier incorporating the latest technology while inheriting the tradition of air acoustics from the past.

Fully balanced circuit configuration is used from input to output.
In addition, the 0 feedback design is adopted following the conventional tradition, and the sound with high freshness is realized.

The volume section uses a resistance switching type volume using a metal film resistor of 1 dB and 66 steps. The volume can be changed by switching this volume with an FET switch.
This realizes smooth volume operation while maintaining the high sound quality of the resistance switching volume, and eliminates noise generation due to contact deterioration, which was a weak point of the resistance switching attenuator, by eliminating moving parts.
Remote control is also available, and the volume value is displayed on the indicator.

Two input terminals, balanced and unbalanced, are installed.
An FET switch is also used in the selector circuit to reliably shut off both the hot and cold sides, and to suppress noise generation during switching by eliminating moving parts.

The built-in microprocessor is designed to be powered off all the time except during processing, eliminating the effect on sound quality.

In consideration of both pure audio and home theater, the Processor Pass-Through mode can be set for each input. This feature allows the input from the AV processor to bypass the volume circuit.

Wireless remote control is included.
