Features

Quick response power supply circuit

The superior power supply circuit adopted by this unit achieves vastly improved response by employing ‘no feedback’ circuitry, toriodal transformers and low impedence parallel main capacitors characteristicly used in professional audio monitoring.

Twin-mono symmetrical construction This receiver offers a new advancement in stereo imaging with the completely independent construction of left/right power amplification units and twin transformers.

Direct construction

In addition to the improved symmetrical design, the signal path of each block is designed for shortest signal path for minimum deterioration of signal clarity.

Wide-Range Linear Circuit

Through this proprietary feedback circuit, an output signal of low impedance offering a flat, even response over the widest possible frequency range is delivered to your speakers.

Sound Retriever

The analog Sound Retriever feature employs new technology that helps remove the adverse effects of compression on audio files by restoring bandwidth and smoothing jagged artifacts left over after they have been compressed, resulting in a wider sound stage.

USB interface

The USB interface allows you to listen to two- channel audio from a PC connected to this receiver.
