High-end channel strip with a discrete preamp with 0dB to +66dB gain based on the Jensen JE990 opamp, a custom HUM Audio Devices input transformer, tweakable Saturation/THD stage with ASYMMETRICAL and SYMMETRICAL modes, a DRY/WET blend knob for parallel processing, a channel direct output with source selector and level control, an innovative TUBE OPTICAL compressor with variable compression/limiting, tube bypass, and L/R stereo linking, advanced side-chain filtering and external key input with AUX 7/8 as side-chain busses, a six-band passive EQ with separate boost/cut controls and switchable shelf/peak modes, and rotary switches for precise settings across EQ, filters, and processing orders, all designed for professional-grade audio flexibility and sonic excellence.

The HUM Audio N-Closure 2 is an advanced channel strip featuring a high-end discrete Mic/Line/Instrument preamp, innovative TUBE OPTICAL compression, an exceptional EQ section with rotary switches for precision, and unparalleled sound-shaping capabilities, designed for professional audio engineers seeking ultimate sonic performance and creative flexibility.

High-End Preamp for Superior Audio Quality

The N-Closure 2 incorporates a discrete Mic/Line/Instrument preamp based on the renowned Jensen JE990, widely considered one of the finest discrete opamps ever designed. This preamp draws inspiration from HUM Audio's flagship RP-2 preamp, celebrated for its rich, musical sound and extraordinary detail. With a gain range of 0dB to +66dB, it delivers pristine audio quality suitable for the most demanding instruments and applications. A custom-made HUM Audio Devices input transformer adds a distinctive sonic character, while a tweakable saturation/THD stage allows users to shape sound creatively by selecting between ASYMMETRICAL (Germanium/Silicon) and SYMMETRICAL (Soft/Medium/Hard) modes.

Parallel Signal Processing for Greater Control

The DRY/WET blend knob enables seamless parallel processing, providing greater control over the tonal balance of signals. A channel direct output with a source selector and adjustable output level facilitates the recording of processed or unprocessed sound. The channel processing order rotary switch allows users to rearrange the sequence of the built-in EQ, compressor, and insert for optimal signal routing. Additionally, the channel meter source rotary switch offers monitoring options for preamp output, tape input, channel output, EQ, compressor, and gain reduction levels.

Innovative TUBE OPTICAL Compressor

The N-Closure 2 features a state-of-the-art TUBE OPTICAL compressor/limiter that combines innovative detection and compression circuits with remarkable sonic transparency. Users can fine-tune the transition between compression and limiting with a dedicated control, or disable compression while driving the tube for warmth and harmonic richness. To preserve the tube’s lifespan, its circuit can be bypassed when not required. A blend knob provides further flexibility for dry/wet processing, while L/R stereo linking ensures cohesive dynamics across adjacent channels. Side-chain filtering and external key input enable advanced compression techniques, and AUX 7 and AUX 8 function as side-chain busses for modern audio workflows.

Versatile and Original EQ Design

The passive EQ section is meticulously designed for creative sound shaping with six bands: HI, MID, and LOW. Separate boost and cut frequency knobs for each band provide unparalleled control. The HI and LOW bands can switch between shelf and peak characteristics, while gentle overlapping curves enhance musicality and ease of use. Independent high-pass and low-pass filters with rotary switches ensure precise recallability, making the N-Closure 2 ideal for multi-channel setups. Its unique EQ design offers a distinctive approach to audio processing rarely found elsewhere.

Precision Engineering for Seamless Integration

Every aspect of the N-Closure 2 demonstrates attention to detail and professional-grade performance. Rotary switches for EQ, HPF, and LPF ensure consistent settings and channel matching, making it a versatile tool for both studio and live environments. This robust design allows audio professionals to achieve consistent results across multiple channels while maintaining the highest audio fidelity.

The HUM Audio N-Closure 2 embodies cutting-edge technology and expert craftsmanship, offering unmatched sonic capabilities for professionals who demand excellence in their audio production tools.
