Terminal 4 by Klavis is a quad-channel essential module that consolidates four independent signal paths, each housing a VCA, a low-pass gate (LPG), and an envelope generator.
Each VCA is DC-coupled, handling both audio and CV with precision, offering flexible amplitude shaping and modulation. They feature linear/logarithmic curve options, offset setting, and zero-crossing switching for clean transitions.
Stereo linking with manual balance and CV control allows for seamless handling of dual-mono or spatialized stereo content.
The LPG section adds a distinct analog character with four dedicated low-pass gates, each offering curated presets of typical warmth and organic sound. This provides tonal flexibility and creative coloration without extra patching.
Clipping LEDs on each channel offer instant visual feedback for level control.
What truly elevates Terminal 4 is its integrated envelope section. Each channel features its own envelope generator with eight distinct templates, adjustable through proportional timing and tailored by linear to logarithmic curvature.
These envelopes can control the internal VCA or LPG directly or be routed out as CV sources for use elsewhere.
This layered architecture allows Terminal 4 to serve as both a dynamic processor and a modulation hub. Whether deployed as a quad VCA, LPG, envelope bank—or all three simultaneously—it offers a powerful, space-conscious solution for nuanced control over amplitude, tone, and timing within a single Eurorack module.
