API / SV14

The API SV14 is an EQ module that faithfully redesigns the APSI 562 EQ, which API sold from the 1970s to the 1980s and enjoyed great popularity. It achieves a high headroom of +24dB and a clean yet warm sound.

■ API 500 Module

■ 4-Band Parametric Equalizer

The SV14 is a simple 4-band EQ module compatible with the 500 series, but its circuit design is rooted in API's history.

It faithfully redesigns the APSI 562 EQ, which API sold from the 1970s to the 1980s and enjoyed great popularity, achieving a high headroom of +24dB and a clean, warm sound.

It also features an in/out switch, transformer-balanced output, boost/cut, and dual concentric knobs for continuous frequency control.
