5. Modes de funcionament i característiques

5.1 NOS/OS Modes

The BR15 R2R offers two distinct decoding modes:

• NOS (Non-Oversampling) Mode: This mode maintains the original sampling rate for decoding, preserving the authentic sound and offering an organic musical experience.
• OS (Oversampling) Mode: This mode upsamples globally to a high sampling rate of 384kHz, providing superior audio performance and a more refined, clear sound. The factory default upsampling rate is 192kHz.

The perceived difference between these modes is subjective. Users are encouraged to experiment to find their preferred listening experience.

5.2 Global 10-band PEQ & AUTO EQ

The BR15 R2R features a Global 10-band Parametric Equalizer (PEQ) and AUTO EQ functionality, accessible through FiiO's proprietary tuning algorithm and dedicated app. This allows users to:

• Access multiple preset sound signatures (e.g., retro, pop).
• Simulate or correct the frequency response of their gear.
• Export, import, share, and save EQ curves.

AUTO EQ simplifies the process by allowing you to upload or select your headphone's original data and desired target curve. Note that PEQ is enabled, the maximum supported sampling rate is PCM 192kHz/24bit. AUTO EQ is currently unavailable under Bluetooth decoding mode.

6. Controls

The BR15 R2R offers flexible control options:

• Front Panel Knobs: For direct control of volume and input selection.
• Comandament a distància per infrarojos: Inclòs per a un funcionament còmode des de la distància.
• Aplicació de control FiiO: A dedicated smartphone application provides comprehensive control over settings, EQ, and other features.

7. Consells d'usuari

• Experiment with NOS/OS Modes: The difference in sound signature between Non-Oversampling (NOS) and Oversampling (OS) modes can be subtle but significant to some listeners. Take time to listen to your favorite tracks in both modes to determine your preference.
• Utilize the FiiO Control App: For advanced customization, such as the 10-band PEQ and other settings, download and use the FiiO Control app on your smartphone. This unlocks the full potential of the BR15 R2R.
• Ensure Proper Cable Connections: Always use high-quality cables and ensure they are securely connected to prevent signal loss or interference, which can degrade audio quality.
• DSD Playback Volume: When playing DSD tracks, a slightly lower volume compared to PCM tracks is normal. Adjust the volume to your usual listening level. The OS menu is bypassed when using DSD mode.
