The 5 Precision Frequency Bands Explained
SoundPlus features a dedicated 5-band hardware equalizer mapped to critical acoustic thresholds:
1. 60 Hz — Sub-Bass & Low-End Rumble
Controls deep bass drops in hip-hop, electronic music, and film scores. Increasing this band gives your earbuds and car audio physical punch without muddying mid-range instruments.
2. 230 Hz — Bass Presence & Kick Drum Warmth
Shapes the body of acoustic guitars, bass guitars, and kick drums. Fine-tuning 230 Hz prevents audio from sounding thin on budget smartphone speakers.
3. 910 Hz — Mid-Range & Vocal Definition
The core frequency of human vocals and lead instruments. Elevating 910 Hz brings recessed vocals to the front of the soundstage.
4. 3.6 kHz — Upper Mids & Presence
Responsible for clarity in snare hits, piano attacks, and speech intelligibility. Crucial for podcasts and vocal-heavy genres.
5. 14 kHz — High Treble & Air
Controls cymbal shimmer and ambient spatial resonance. Adding subtle gain at 14 kHz produces a high-end, open soundstage in premium headphones.
Bass Boost & Crossfade Features
In addition to graphic equalization, SoundPlus integrates specialized signal processing:
- Hardware Bass Booster: Dynamically amplifies sub-harmonics without clipping or distorting peak amplitudes.
- Smooth Audio Crossfade: Eliminates abrupt silence between tracks by seamlessly blending the outgoing track's fadeout with the incoming track's intro.
- Pre-Configured Audio Profiles: Instant one-tap presets for Flat, Bass Boost, Vocal Clarity, Electronic, and Rock.
