 Channel Strips

N-Trophy is a fully discrete, modular analog in-line console designed to become the heart of a modern analog or hybrid studio, where sound quality and fast, creative work is a key. Where you don’t want to be overwhelmed by increasingly complex technology, but focus on the art itself. That is the way it should be. And all that you will experience with N-Trophy is just that.
And that is exactly what you will experience with N‑closure channel strips.

nclosure-main

Back to The Nature of Sound. Carefully handcrafted in Poland.

A beautiful and inspiring classic look is combined with an innovative approach to working on analog console. N‑Trophy is an exceptional console in so many aspects, like never before. It removes digital ’junk’, and brings life, vitality, air, space and depth back to your tracks. It brings back the pleasant feeling of communing with what is close to every human being by nature꞉ the beauty of analogue sound. Truly, the N‑closure channel strips give you a ’Back to The Nature of Sound’ experience.

How did we do it? The secret behind the N‑Trophy

We designed High‑End discrete class A mic preamps, custom audio transformers and discrete opamps, as well as unique six‑band passive EQ, THD Stage, and the Tube Optical Compressor / Limiter with innovative detection and compression circuits that work differently than ones found in other studio equipment. At the same time, we eliminated all points where classic analog consoles used to be weak or overcomplicated. The signal path is also as short as it can be, despite the plenty of N‑Trophy’s and N‑closure’s sound shaping tools.

To complete the N‑Trophy and N‑closure design, we have also taken special care to develop the classic linear power supply with a custom double‑shielded toroidal transformer and the best Linear Technology voltage regulators. The transformer here is acting as a power conditioner, ensuring large headroom and very low noise performance.

N‑closure2 

N‑closure2 is a 4U device housing a maximum of two N‑Trophy console channel strips mounted horizontally, and N‑closure6 is an 11U

 

N‑closure6

N-closure6 is the perfect solution if you wish to expand your setup with more than two channel strips and have a console‑like furniture. With channels mounted in a similar way to the N‑Trophy channel strips, you will have a great console‑like experience. You can order N‑closure6 with any number of channel strips installed, and then expand your system as your studio grows. Empty spaces without installed channel strips are filled with blank panels.

 

Connections and studio integration

On the rear panel of the N‑closure, you will find an AC power socket and balanced XLR and Combo sockets – identical to the sockets on the rear panel of the N‑Trophy channel section. The only difference is the number of connector sections, depending on whether it is the N‑closure2 or the N‑closure6 housing. The sockets are꞉

KEY1,
KEY2꞉

Global line inputs for an external sidechain compressor/limiter circuit. All installed channel strips have a switch to select which KEY input they use.

INS SEND,
INS RET꞉

Line inputs/outputs for each channel’s external insert loop.

DIR OUT꞉

Channel line output. Output point can be selected individually, on each channel strip꞉ after the preamp or after all processing in the channel.

LINE IN꞉

Input for processing line‑level signals. A typical scenario is that you use it when the N‑closure in connected to other analog equipment in the chain.

TAPE IN꞉

Channel’s second line level input. Selectable with a dedicated switch. This input is intended for use as a DAW audio signal input, without the necessity of switching cables between LINE and TAPE inputs.

MIC IN꞉

Mic‑level input to the channel mic preamplifier.

Creative tools you will find in N‑closure channel strips꞉

N‑closure channel strips are taken directly from our N‑Trophy All Discrete Analog Console. Sound quality and all features are identical,
except those related to the N‑Trophy Centre Section꞉ Auxes, signal routing to Groups, Panning and MixB section.

HIGH ‑END DISCRETE CLASS A Mic/Line/Instrument PREAMPS

They are based on legendary Jensen JE990 opamps. It’s a similar topology to the preamps found in our flagship RP‑2 preamp, and in practice one of the best sounds you can get from a mic preamp anywhere꞉ big, vital, pushed forward, full of life and with a lot of details. Perfectly balanced, bringing out the nuances of the sound beautifully, yet not exaggerated in any way. It is equally good for clean, beautiful‑sounding classic recordings, as well as providing a solid foundation for colouring and tweaking the sound with N‑closure tools when working with other musical genres.

CUSTOM MADE BEAUTIFULLY SOUNDING AUDIO TRANSFORMER

It adds class and size to the sound, enriching it, filling the space and giving even more analog taste. The same transformer is used in the N‑Trophy Mastering Console.

THD SATURATION / DISTORTION STAGE

With level knob and plenty of colours and various harmonic additions꞉ German, Silicon (ASYMETRICAL) and Soft, Mid, Hard (SYMETRICAL). Soft mode is especially great for analog tape simulation.

TUBE OPTICAL COMPRESSOR / LIMITER

Our original design of a very creative and extremely effective dynamics section, is equally good for keeping vocals in place and for ’crushing’ drums and even for special effects purposes. It works great on everything, thanks to its continuously adjustable characteristics꞉ from compressor (slower, gluey sound, LA‑2A type) to limiter (fast, FET‑like type 1176). All possible sidechain options are at your disposal, along with a High Pass Filter, external KEY inputs and stereo link for detection circuits. Attack and Release are automatically changed along with the compression level, so the compressor is very quick and intuitive to use, and you will achieve the desired sound in seconds. The ECC88 (6N23P) tube is placed in the Gain Makeup stage, and you have the option to bypass the compressor, but still use the tube to add a beautiful tone to your track.

SIX ‑BAND PASSIVE EQ WITH WIDE SLOPES AND LPF/HPF FILTERS

Our original design of an amazingly musical‑sounding mastering grade equalizer. We have spent a great deal of time on the perfect selection of frequencies and how the bands overlap. The idea behind the equalizer is to find the right balance of your sound quickly and creatively. Once you start using it, you’ll see how fast and intuitive it is, and how beautifully it brings out the ’life’ and three‑dimensional space of your recordings. N‑closure equalizer uses rotary switches just like all mastering equalizers. Its phase and characteristics are perfectly matched, so you can use it with confidence on multiple channels with the same settings, achieving identical sound.

ROUTING WITH VARIABLE ORDER OF BLOCKS꞉ INSERT, COMPRESSOR, EQ

All audio signal routing is lossless, passive, based on relays with gold‑plated contacts.

Modularity. Easy user expandable per channel.

Well-thought-out and simple studio integration with onboard or remote patchbay.

One console for all recording, mixing and mastering tasks

Moving Fader automation, controllable by DAW.

Easy installation, expansion and service maintenance.

Power efficiency and silence.

Wide installation options.

Group Channels:

N-Trophy has 8 mono Group Busses, which is more useful than ordinary stereo ones. By hard panning Left / Right, you have perfectly matched stereo groups.

All groups are the same quality as the Main MIX Bus and are based on our proprietary design of Summing Matrix, with discrete Jensen JE990 opamps.

Groups have also external XLR inputs straight to the fader, so you can use them for summing external sources, instead of routing signals from channels.

8 mono AUX RETURNS with Pan pot and routing to MAIN Mix or to Groups 7-8. Each Return is equipped with a PAN MODE switch (L<PAN>R) similar to that available in all channels, allowing for perfect stereo separation when needed.
All AUX Returns have identical quality like input channels, so they are perfect for stem summing / mastering applications when you order N-Trophy in a form of a Center Section alone. SOLO SAFE switch protects AUX RETURN from muting, similar to the channel’s SOLO PROTECT.

8 mono AUX MASTERS.
Each is equipped with HPF and LPF filters, identical to filters found in channel strips. You can independently switch on / off each AUX MASTER.

8 mono pre or post-fader AUX SENDS for each mono Group bus. This feature is unusual in analog studio consoles but opens many new possibilities.

When you use AUX 7 or AUX 8 as internal sidechain busses, you can also send key signals from groups. You can even freely mix different portions of keying signals from different groups and channels for unlimited creative compression. Each N-Trophy’s compressor has access to these sidechain signals.

Group inserts with Dry / Wet Blend feature. Blending is done using rotary switches. It is easily recallable and ensures perfect stereo matching of adjacent groups.

Group PAN knobs with PAN MODE switches, similar to that found in channels and AUX RETURNS.

Stereo WIDTH adjustment on each stereo group, with fantastic results. It is our proprietary design module, that works in a different way than the typical width adjustment found in some studio processors. It preserves low-end energy and has no influence on the centre of the stereo image when adding dimension to tracks. It is a similar design to one found in our LAAL – Analog Look Ahead Mastering Limiter.

Space for the current standard full-size wireless MAC or PC keyboard. For PC users we recommend using Logitech MX wireless keys.

Classic scribble strip for group tracks and earphone outs description with a dry marker.

Highly reliable MUTE and 0dB buttons. 0 dB button for bypassing fader, and setting channel output level at fader unity gain for straight summing purposes. Fader itself can control the DAW fader level if this option is selected in Center Section’s Automation Setup.

100mm high precision stepped motorized faders based on fixed resistors.

This is an absolutely unique HUM Audio Devices design of ultra-precise, high-resolution stepped analog fader. Up to now, it was impossible to achieve this level of accuracy in analog consoles, using standard analog faders. Our design ensures fader position settings are ideally matched and repeatable through all console channels. It is a fantastic feature for precise stem summing and/or mastering applications.

Classic Flying Fader design is the best quality solution. We do not use any VCA, which could lead to sound loss. High resolution of DAW automation. N-Trophy’s fader scale exactly matches the Pro Tools fader scale, for user convenience.

Freely change the order of EQ, Compressor, and MIX Insert Matrix and put built-in M/S encoder and decoder between them wherever you like. You can mix M/S and Stereo processing modes. Use our exceptional LAAL analog brickwall limiter for completing your work with the best sound reachable in analog domain. Ideal solution for today’s artists / producers who more and more often master their work on their own. When quality and fast creative work is a key, our N-Trophy console is the go-to solution.

TUBE OPTICAL Master Compressor / Limiter: B a s ed on NOS Mullards, considered the best-sounding tubes ever. Works in L/R on M/S modes according to the M/S chain setting. All compressor settings are on easily recallable rotary switches.

Innovative detection and compression circuits. Variable transition between compression and limiting with a dedicated knob. You can switch off compression, but still use tube sound, or turn off the tube as well.

– BLEND knob for dry/wet processing. – L/R link for both channels. – Side Chain filter and external KEY input. – AUX 7 & AUX 8 can serve as Compressor sidechain buses, for modern creative compression techniques.

Passive Master EQ with separate Boost and Cut frequency knobs. Total of 6 bands: HI, MID and LOW. HI and LOW bands can be switched between shelf / peak characteristics. Works in L/R or M/S modes. This is an original design of EQ, impossible to find anywhere else, and with a special purpose. With gentle overlapping curves for fast and creative sound shaping with a lot of musicality. EQ, HPF, and LPF filters use rotary switches, so they are easily recallable, and multiple channels are perfectly matched to have the same characteristics.
Both EQ and Tube Compressor are additionally available on N-Trophy’s patchbay for external use. It is selectable by toggle switch independently for each one of them – INT(MIX) / EXT(XLR).
