DEVELOPED IN PARTNERSHIP WITH SERATO
NS7FX was a collaborative development effort with Serato to develop the finest computer-DJ experience. It is a one-to-one hands-on control instrument for Serato ITCH.
Because it was designed for ITCH, NS7FX setup time is the bare minimum. No tweaking, no mapping; just plug and perform.
PERFECT FEEL
Forget your experiences with other controllers. NS7FX has two seven-inch, motorized, high-torque aluminum turntable platters. The turntable controls feature modern and classic settings that alter the feel to model the feel you prefer. Seven-inch, legit vinyl records with 45RPM adapters sit on real slipmats. There’s no simulation here – NS7 is the real deal.
Solid, rugged, rubberized buttons and knobs compliment a high precision, replaceable CP-PRO crossfader and D-TYPE line faders for an unquestionably high-quality feel. We selected the CP-PRO digital-VCA crossfader because it is outstandingly durable with low wear for a long life. It has a solid feel that is smooth and rigid. It’s only natural that our finest crossfader is a component of our finest controller. We selected high-performance, D-Type digital-VCA line faders for their rugged, long-life performance. Like the crossfader, the line faders are replaceable. The crossfader offers contour adjust and reverse adjustment, enabling you to customize its operation.
SYSTEM SIMPLICITY
Forget the mouse. Forget the keyboard. NS7FX renders ITCH software perfectly simple to operate, with its click knob and large, backlit buttons navigating though your music library. You’ll spend less time looking at the screen and more time enjoying performing thanks to the visual feedback you get from NS7FX’s more-than 100 LEDs and more-than 100 hands-on controls.
NS7FX has onboard audio outputs so it’s the only piece of gear you need to connect to the PA system or powered speakers. NS7FX outputs 24-bit, 44.1 kHz digital audio to the sound system on XLRs and RCAs. The front panel contains mic input, RCA line input, and both 1/4" and 1/8” headphone outputs with volume control.
NS7FX comes with an integrated laptop stand that supplies safe, secure mounting for your laptop. You can use an ultra-small space because NS7FX elevates your laptop off the table. The NSFX effect controller mounts conveniently on the laptop stand for integrated effects control without taking up any additional space in your setup.
PRECISION CONTROL
NS7FX sends control information over USB at more than ten times the standard MIDI rate. This innovative communication technique yields extremely high-precision, low-latency control.
There’s nothing like dropping the needle on a record for quickly locating a point in the track. We took that idea and developed our own modern take on it with Strip Search, the unique virtual-needle-drop touch strip. You can locate a point instantly within the track using the on-screen waveform and Strip Search.
Five hot-cue-assign buttons on each deck digitally mark your cues on the track. These marker points are recallable in ITCH and Scratch LIVE, and you can load Scratch LIVE cue points in ITCH.
We developed an extensive Serato-style loop section on each deck for creative remix capabilities. You can choose between manual and auto-loop functions and an automatic BPM analyzer further assists loop makers. Creating automatic smart loops of any measure length is a breeze, and you can mutilate and modify to heart’s content with a variety of controls such as Doubling, Halving, Shift, and manual controls. Multiple loop banks per deck make NS7FX a great choice for scratch and club DJs alike.
Beat matching is straight ahead with 100mm, smooth, stiff pitch sliders and plus and minus buttons, by popular request, for bending. There’s a zero-point LED, so it’s easy to know when you’re in the middle.
AUDIO QUALITY
We took extraordinary care in selecting the components of the audio signal chain. NS7FX contains a host of professional audio connectors and a multichannel, 24-bit USB digital-audio interface.
The high-definition post-mix analog audio output features a minimized circuit path with containing only one audiophile-grade bipolar capacitor. This optimized design maximizes phase coherence, ensuring that audio is tight and punchy.
PROFESSIONAL APPEARANCE
NS7FX’s dual decks flank the mixer section. Its recognizable, professional appearance is supported by clean design in matte and glossy black. The entire unit is housed in a heavy-gauge, industrial-strength metal casing that is ready for the torture of travel.
SERATO ITCH SOFTWARE
Serato ITCH is already familiar if you use Scratch LIVE. The new program builds on Scratch LIVE’s popularity and adds some key, new features. ITCH doesn’t require a timecode interface, so the system can be as simple as, say, NS7FX and your computer! Since ITCH makes timecode a thing of the past, you won’t need to worry about needles skipping or vinyl wearing out. You can load your Scratch LIVE crates, loops, presets, and cue points seamlessly in ITCH. NS7FX also works with most other MIDI DJ software and supports iTunes.
ITCH is a high-performance portable music system with internal mixing and platter-style playback control. Because it is designed specifically for use with hardware control, ITCH has a clean information display.
ITCH handles audio processing and mixing including channel fading, EQ, crossfading and track trim are processed for outstanding control and management of your tracks, ease of recording your set, clip-proof gain management, and BPM calculation using the power of your computer’s processor.
Serato's unique color waveforms provide an easy identification of sound and changes in the track. ITCH can set and store cue-points. It offers three-range pitch control: ±8%, ±16%, and ±50% with Key Lock for manipulation of pitch and tempo independently.
ITCH has library management tools for backup and restoring your music. Advanced input and mix recording capabilities include recording your mix or just the aux input for sampling. The software supports AIFF, WAV, MP3, and AAC audio files.
The History function in ITCH keeps a comprehensive record of every track played and exports sessions from your history to 'txt', 'csv', or 'm3u'. ITCH also has a Loop Roll function that provides a looping effect where the playhead jumps back to normal time when you release the loop. Built-in key support ensures that ITCH reads key tags from MP3 files and displays them in the 'key' column in your library.

élite Series Overview
Yorkville’s élite series loudspeaker systems are the result of years of research, pushing the limits of modern state-of-the-art sound reinforcement technology. Engineered for the serious pro audio user, élite systems are among the most advanced, most versatile and most efficient high powered portable P.A. boxes available.Today’s élites, from the highly efficient two-way E10 to the 1500 watt E2152 have some of the most advanced component protection and crossover technology available today. They have been carefully designed to bring you the latest in Yorkville’s advanced loudspeaker engineering.
Ideal for any small PA rental house, installer or sound company, these loudspeakers may replace a number of specific application cabinets in any inventory.
A modified trapezoidal shape and recessed input jack panel and handles mean these cabinets can function perfectly as a wedge monitor or front-of-house loudspeaker. Unlike some ‘multi-function’ loudspeakers currently in the marketplace, great care has been taken in the design process to ensure that élite cabinets will perform without compromising functionality as either a monitor or a front-of-house enclosure. Neither application was considered as an afterthought.
Several of the élite loudspeakers are loaded with 80° x 50° rotatable ABS Waveguide horn assemblies (the E10 utilizes a 100° x 25° horn). The ability to rotate the horn assembly ensures that the cabinet can provide optimum high frequency dispersion when the loudspeaker is used in either a vertical, horizontal or arrayed application.
Integrated stand mount adapters and flyware means these enclosures can be utilized in any permanent install or touring application. In addition, the modified cabinet shape means the élite series can be installed much closer to vertical surfaces and in some cases, under balconies in tight locations, and can be arrayed in a much tighter less obtrusive cluster.
Of course, the élite series has retained the features and high quality sound that have made them so popular including Yorkville's famous two year (even if you break it!) transferable warranty.*
Advanced technology
- Compact and simple to operate
- Linear, full range frequency response
- Time aligned with low distortion
- High power handling, high efficiency, high SPL
- High efficiency, high excursion, linear response drivers.
- High definition, high slope internal passive crossovers.
- Computer modeled enclosure designs to accommodate greater driver dynamics.
- Unique protection networks capable of reacting equally to power overloads and input distortion levels.
- Dual purpose electronic processors specifically designed to enhance bass response and to act as stereo crossovers when bi-amping with subwoofers.
The majority of the élite range feature seamless driver interaction through sophisticated high-slope passive networks and ingenious component protection schemes. Rugged jackplates are inset and include a combination of both Speakon™ and 1/4" phone jack inputs.
Advanced PTC™ Horn Protection makes its debut in the élite series.
PTC™ is an ingenious current sensing / self resetting breaker that offers some serious advantages over current protection schemes used in many loudspeaker cabinets. This protection scheme, while always present in the signal path, remains inaudible until it becomes necessary for it to react. It kicks in at a point where it effectively reduces output to the horn and protects that diaphragm from damage due to excessive power input or signal distortion. Unlike a breaker it does not require a physical reset to allow signal back to the horn driver, and unlike a bulb or fuse, does not need to be replaced if the circuit is tripped, and the fuse is blown.
Where PTC™ shines is in heavy feedback environments where most horn diaphragm damage occurs. In rare situations even where a microphone might be dropped in a monitor, the sustained ‘squeal’ can destroy diaphragms in seconds. PTC™ will significantly reduce output level to the horn to protect the diaphragm. When the situation has been rectified, and the feedback eliminated the horn will return to full operating level within half a second.
The E2152 features the ATP™ (Active-Transistor) protection system, which allows the horn driver to operate at levels significantly above those required for normal operation. The ATP™ brickwall element of the protection circuit uses power transistors configured to operate linearly yet have the fast attack required to protect against harmful transients. Along with ATP™, the crossover also incorporates air core coils and polypropylene capacitors to guarantee reliable and distortion free operation at extreme levels. The sonic benefit is higher output and greater transparency when operating at high levels.
élite Series Characteristics
Processor ControlledFull function stereo analog processors that are configurable for passive or bi-amp operation, as well as live or recorded music applications make sure that your élite system is always tuned and ready.
Rugged Driver Mounting System
All élite cabinets feature a specially reinforced driver mounting system that makes sure the horn drivers will still be attached to the horns when you get to the show. The ABS or composite horns are pressure fitted to the driver which is bolted to the internal driver support.
Custom Design Horns
Custom ABS plastic and composite horns are specifically designed for each cabinet and manufactured right in our factory for optimum quality control. This insures proper waveguide output for better clarity and lower distortion.
Rugged Black Carpet Covering
The stylish yet practical carpet that covers the élite cabinets keeps them looking great. The two part rubberized glue that is used to attach the carpet ensures that élite cabinets will stand up against moisture by effectively wrapping the cabinet in a rubber glove.
Curved Metal Speaker Grilles
Curved metal grilles absorb shocks evenly to resist dings and dents while eliminating frequency resonance. The trapezoidal cabinet shape allows for arrayable performance without phase cancellation.
Recessed Handles
All élite cabinets feature attractively recessed bar handles. Great care is taken to make sure that they "stay out of the way", but are easy to get at when you need them.
Flush Mounted Stand Adapters
Flush-mounted stand adapters in the top of the subs and bottom of the full-range speakers allow the use of the adjustable SW-TELETUBE option which makes setup a breeze by eliminating the need for speaker stands.
Integrated Wheels
Tilt back wheels and top-mounted handles are standard issue on the larger cabinets such as the E215, E2152, LS1208 and LS1004.
élite Series
LS1208 - Subwoofer - 1200w, 18 inch
Additional research has developed a woofer with significantly higher power handling than any other speaker that we currently use, making the LS1208 one of the highest output subwoofers available at any price. Performance, packaging, and overall value make the LS1208 a benchmark.
Features
Suitable for touring or fixed installations, the cabinets are constructed of 15mm 11-ply Baltic Birch with heavy internal bracing for reduced resonance and better durability. The enclosure is covered in a black carpet covering and incorporates metal corner protectors, rugged curved anti-resonant metal grilles, and 1/4" or Speakon™ input connectors. An optional finish of black ultrathane paint (LS1208B) is also available. Additionally, the Speakon™ connectors feature a configuration switch which allows instant reversal of Speakon™ jack pinouts for easy single wire hook-up using optional four wire Speakon™ cables. The LS1208 includes tilt-back wheels and top/rear mounted corner handles for better maneuverability and stacking (wheels don't fall in the handles!!).Specifications
