Commentary

An MD deck equipped with a sampling converter that enables digital recording from devices with different sampling frequencies.

20-bit processing is used to ensure a high level of sound quality throughout recording and playback.
20-bit A/D converter digital processing is used for recording analog signals such as FM broadcasts and records, and all 16-bit digital signals such as CDs are recorded in 20-bit data format.
In addition, a 20-bit D/A converter is used for playback to ensure micro-level reproduction and dynamic range.
In addition, a 32 x oversampling digital filter is incorporated to transmit quantization noise outside the audible range and to achieve clean sound reproduction.

In the power supply section, analog and digital circuits are wound separately to solve the problem of digital noise flowing into the audio circuit.

A damping insulator is used to suppress unwanted external vibration.
In addition, side panels and bottom plates of the chassis are provided with ribs (dents) to increase rigidity while suppressing resonance.

Equipped with digital input of the total Route 3 of 2 optical input systems and 1 coaxial input system.

It is equipped with a sampling rate converter to dub digital signals from sources with different sampling frequencies, such as CS-PCM and DAT.
In addition, ATRAC with 24-bit arithmetic processing is adopted in order to perform high-precision signal compression and expansion.

Recording or playback is possible with an external timer.

Synchronized recording function is possible in combination with Onkyo CD player with RI mark.

Equipped with functions such as title input, editing function, music selection function, timer standby function, synchronous recording function, AMCS dial function, etc.

Wireless remote control is included.
