The UAD 4K Channel Strip captures the iconic sound of the SSL 4000 console channel with precise circuit emulation of the 4000 G+ model. It features the renowned Type E four-band EQ, known as the "black knob" EQ, which is highly regarded for its musicality and clarity. This channel strip replicates the classic SSL filters and EQ characteristics, offering users a trusted tool for shaping their audio with authenticity and ease.

This channel strip includes a comprehensive set of dynamic processing tools such as high and low cut filters, an independent Expander/Gate, and a Compressor/Limiter section. The parametric middle EQ bands provide detailed control, while the high and low bands offer switchable bell or shelving options. The compressor offers flexible control over threshold, ratio, attack, and release times, allowing for a broad range of compression styles from subtle to aggressive. The gate includes a unique "no-chatter" mode that reduces noise artifacts, enhancing its responsiveness and usability.

Additional features include a PRE-DYN button that changes the signal flow to place EQ before dynamics for different tonal shaping possibilities. The DYN-SC function enables frequency-dependent compression by routing the EQ or filters into the dynamics sidechain, providing creative control over the compression response. A Link button allows stereo sidechain linking or unlinking, making this channel strip suitable for precise stereo processing needs. The UAD 4K Channel Strip delivers a powerful combination of classic SSL tone and modern flexibility for mixing engineers.
