Technical specifications for the K688 list a dual-output topology consisting of XLR and USB-C interfaces. The dynamic capsule provides a frequency response range of 70Hz to 15kHz, while the digital path supports 16-bit resolution at sample rates of 44.1kHz to 48kHz. Material analysis confirms a zinc alloy chassis, marketed as the "Amplitank" construction.
Performance metrics demonstrate high off-axis rejection via a cardioid pickup pattern, suitable for environments with high ambient noise. The internal circuit features a capacitive touch mute sensor and a 3.5mm latency-free monitoring jack that draws signal directly from the DSP. The analog XLR path bypasses internal conversion, allowing for integration with high-fidelity 24-bit external interfaces.
Integrating this unit with smart docking stations can ensure stable power delivery for the internal monitoring circuit.
This hybrid device serves as a versatile component within the studio USB microphones landscape.
