• High headroom with +24 dB clip level
• Compatible with API 500 VPR racks and lunchboxes®.

TheAPI Audio SV14 is a 4-band parametric equalizer in 500-series format, designed closely inspired by the famous APSI 562 EQ distributed by API in the 1970s and 1980s. With its re-engineered circuitry, it offers professional performance at a competitive price, while maintaining the brand's signature warmth and musicality.

Design inspired by API history

The SV14's construction philosophy takes the strengths of historic models and combines them with modern implementation. Each band offers independent and continuous controls for frequency and gain adjustment, allowing precise and musical interventions in any mix or recording context.
