Electronically identical to the N-TROPHY console channel strip, without the console-specific Center Section functions (aux routing, group routing, panning, MixB section). Each module is a self-contained Class-A signal path with a full complement of processing tools: a discrete Mic\/Line\/Hi-Z preamp based on Jensen JE990 opamps (0–66 dB gain), a switchable input audio transformer, a THD stage with five saturation types, a tube optical compressor using an ECC88 tube, a 6-band passive EQ with HPF\/LPF, an insert loop with Dry\/Wet Blend, and an output trim with source selector. All signal routing is relay-switched with gold-plated contacts throughout. Hand-built in Poland.\u003c\/p\u003e\n\n  \u003ch3\u003ePreamp, transformer, and THD stage — three coloration layers at the input\u003c\/h3\u003e\n  \u003cp\u003eThe Mic\/Line\/Hi-Z preamp based on Jensen JE990 opamps, using a topology derived from HUM Audio's flagship RP-2 preamplifier, delivers 0–66 dB of gain in 12 stepped positions. Microphone input impedance is 3.5 kOhm, line is 10 kOhm, and Hi-Z exceeds 1 MOhm; maximum input level is +22 dBV; 48V phantom power is switchable. An optional input transformer (X-FORMER) can be engaged via relay between the preamp and EQ, adding subtle harmonic enhancement at low frequencies and a gentle analog roll-off at extreme levels without loss of detail. The THD stage offers five harmonic saturation types: ASYMMETRICAL Germanium, ASYMMETRICAL Silicon, and SYMMETRICAL Soft\/Medium\/Hard — covering the range from gentle analog warmth through deliberate germanium or silicon transistor-style drive. A Tape input with a 0\/+6\/+12 dB gain switch is included. Phase inversion is available independently per input type (Mic, Line, Tape).\u003c\/p\u003e\n\n  \u003ch3\u003eTube optical compressor, passive EQ, and configurable processor order\u003c\/h3\u003e\n  \u003cp\u003eThe tube optical compressor with an ECC88 tube offers continuously variable behavior from slow, gluey optical-style compression (LA-2A type) to fast, FET-style limiting (1176-type) on a single morphing control — no threshold selection needed. A Dry\/Wet Blend enables parallel compression at any ratio. An HPF in the internal sidechain detection circuit, two external KEY inputs (KEY1\/KEY2), stereo link, and AUX 7+8 as sidechain buses support advanced dynamic processing configurations. The tube circuit can be bypassed independently from the compressor function — allowing clean compression without tube saturation, and preserving tube life when compression is not in use. A Sifam VU meter displays Post Gain, Gain Reduction, Trim, or Input (active only when insert is engaged). The 6-band passive EQ features separate Boost and Cut controls per band; HF and LF bands switch between Peak and Shelf modes; HPF and LPF at 6 dB\/oct each with frequency selection on rotary switches for full recallability. External insert loop with balanced XLR connections and Dry\/Wet Blend for parallel external processing. Processor order in the signal chain is freely configurable via relay switching across six permutations of Preamp \/ EQ \/ Compressor \/ Insert. Output Trim with source selector and level control.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eSingle N-Strip module — electronically identical to N-TROPHY console channel (without Center Section functions)\u003c\/li\u003e\n    \u003cli\u003eDesigned for N-Closure 2 housing (up to 2 modules, 4U) or N-Closure 6 housing (up to 6 modules, 11U)\u003c\/li\u003e\n    \u003cli\u003eDiscrete Class-A Mic\/Line\/Hi-Z preamp on Jensen JE990 — 0–66 dB gain, 12 positions\u003c\/li\u003e\n    \u003cli\u003eInput impedances: Mic 3.5 kOhm \/ Line 10 kOhm \/ Hi-Z above 1 MOhm\u003c\/li\u003e\n    \u003cli\u003e48V phantom power; phase inversion per input type; Tape input with 0\/+6\/+12 dB gain switch\u003c\/li\u003e\n    \u003cli\u003eSwitchable input transformer (X-FORMER) — harmonic enhancement LF, analog HF roll-off\u003c\/li\u003e\n    \u003cli\u003eTHD Stage: 5 saturation types (Germanium, Silicon asymmetrical; Soft\/Medium\/Hard symmetrical)\u003c\/li\u003e\n    \u003cli\u003eTube optical compressor ECC88 — continuous Comp→Lim morph, Dry\/Wet Blend, stereo link\u003c\/li\u003e\n    \u003cli\u003eSidechain: internal HPF, KEY1\/KEY2 external inputs, AUX 7+8 as sidechain buses\u003c\/li\u003e\n    \u003cli\u003eIndependent tube bypass — clean compression without tube saturation; tube life preservation\u003c\/li\u003e\n    \u003cli\u003e6-band passive EQ with separate Boost\/Cut per band; switchable Peak\/Shelf on HF and LF\u003c\/li\u003e\n    \u003cli\u003eHPF and LPF 6 dB\/oct with frequency selection on rotary switches\u003c\/li\u003e\n    \u003cli\u003eExternal insert loop XLR balanced with Dry\/Wet Blend — parallel processing\u003c\/li\u003e\n    \u003cli\u003e6 freely configurable processor orders in signal chain (relay-switched)\u003c\/li\u003e\n    \u003cli\u003eSifam VU meter: Post Gain \/ Gain Reduction \/ Trim \/ Input (with active insert)\u003c\/li\u003e\n    \u003cli\u003eOutput Trim with source selector and level control\u003c\/li\u003e\n    \u003cli\u003eAll signal routing via relay switches with gold-plated contacts\u003c\/li\u003e\n    \u003cli\u003e100mm stepped motorized fader on fixed resistors (identical to N-TROPHY)\u003c\/li\u003e\n    \u003cli\u003eHand-built in Poland\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eType: single channel strip module (N-Strip) for N-Closure 2 or N-Closure 6 housing\u003c\/li\u003e\n    \u003cli\u003eSignal path: discrete, Class-A, balanced, relay-switched throughout\u003c\/li\u003e\n    \u003cli\u003ePreamp: Jensen JE990, gain 0–66 dB (12 steps)\u003c\/li\u003e\n    \u003cli\u003eInput impedance Mic: 3.5 kOhm; Line: 10 kOhm; Hi-Z: above 1 MOhm\u003c\/li\u003e\n    \u003cli\u003eMaximum input level: +22 dBV\u003c\/li\u003e\n    \u003cli\u003ePhantom power: 48V\u003c\/li\u003e\n    \u003cli\u003eInput transformer: switchable (X-FORMER, optional in signal path)\u003c\/li\u003e\n    \u003cli\u003eTHD Stage: 5 types (Germanium, Silicon, Soft, Medium, Hard)\u003c\/li\u003e\n    \u003cli\u003eCompressor: opto with ECC88 tube, continuous Comp→Lim morph, Dry\/Wet, stereo link\u003c\/li\u003e\n    \u003cli\u003eCompressor sidechain: internal HPF, KEY1\/KEY2 external, AUX 7+8\u003c\/li\u003e\n    \u003cli\u003eEQ: 6-band passive, separate Boost\/Cut per band, switchable Peak\/Shelf on HF\/LF\u003c\/li\u003e\n    \u003cli\u003eHPF\/LPF: 6 dB\/oct, frequency selectable on rotary switch\u003c\/li\u003e\n    \u003cli\u003eInsert: balanced XLR, Dry\/Wet Blend\u003c\/li\u003e\n    \u003cli\u003eProcessor order: 6 configurations (relay-switched)\u003c\/li\u003e\n    \u003cli\u003eVU meter: Sifam, modes Post Gain \/ GR \/ Trim \/ Input\u003c\/li\u003e\n    \u003cli\u003eFader: 100mm stepped motorized (fixed resistors)\u003c\/li\u003e\n    \u003cli\u003eRouting: relay switches with gold-plated contacts throughout\u003c\/li\u003e\n    \u003cli\u003eProduction: hand-built, Poland\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"HUM Audio","offers":[{"title":"Default Title","offer_id":53745438294353,"sku":"58396","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/HUMAudioN-Closure_module_1.jpg?v=1778576384","url":"https:\/\/wrdtunes.com\/fr\/products\/hum-audio-n-closure-module","provider":"Wired Tunes","version":"1.0","type":"link"}
