2. Característiques del producte

The SANSUI SMC-300BT system integrates advanced audio technologies to deliver a superior listening experience:

• Híbrid AmpDisseny de lifier: Features a vacuum tube in the pre-amplifier's first stage, generating even-order harmonic distortion for a rich, warm, and natural sound. The second stage incorporates a digital power amplifier for dynamic, delicate, and powerful audio reproduction.
• Advanced Speaker Cone Technology: Utilizes a unique "double papermaking method" inspired by traditional Japanese paper. The speaker cone surface uses "Mitsumata" Japanese paper for clear mid-high frequencies, while the reverse side employs highly elastic pulp material for rich low frequencies.
• Múltiples opcions de reproducció: Supports CD, CD-R, CD-RW, CD-DA, MP3, and WMA formats.
• Connectivitat sense fils: Built-in Bluetooth for seamless streaming from compatible devices.
• Sintonitzador FM: Integrated FM tuner (76-108MHz) for radio reception.
• Reproducció USB: USB port for playing audio files de dispositius d'emmagatzematge USB.
• External Audio Input: Two auxiliary input systems for connecting external audio sources.
• Potència de sortida: 60 watts total audio output.
