EF500P - Powered Speaker - 800w, 15 inch / 2 inch
The EF500P redefines performance in a high-power professional active loudspeaker enclosure. Utilizing the popular Úlite EF508 as a base, and adding a total of 800 watts of bi-amped power and advanced signal processing, the EF500P is destined to set a new standard for active loudspeaker design. The woofer or low frequency amplifier uses Class D switching technology to reduce overall weight of the amplifier section. This amp delivers over 650 watts to the 15" woofer. A 150 watt two-tier linear technology class H amplifier drives the 2" titanium diaphragm horn driver. This solution allows the horn to produce loud clean transients to keep up with the high output of the woofer. The two-tier amplifier technology isn't typically seen in a product like this, however we found the advantages (lower weight, more efficiency, higher headroom and lower operating temperature) made it a perfect choice for powering the top end.

This combination of amplifier technologies keeps distortion to a minimum while reducing the heat dissipation to a level low enough to eliminate the need for heavy heatsinks for the overall power stage. As an additional advantage, our unique combination of two-tier and Class D amplification has reduced extraneous heat to the point that EF500P can easily be used in any orientation, and close to walls, floors and in close arrays with multiple cabinets. We have found that competitive active loudspeakers with large finned heatsinks need to be operated vertically and with clearance to ensure proper heat dissipation and ventilation. Since the EF500P is ideal for flying in large clusters and in point source concert sound systems, our designers took extra care making sure that in tight clusters overheating would not be an issue.

EF500P - Mixer / Amplifier Module We've also found an opportunity to tweak the electronics for maximum overall speaker performance and protection. Borrowing some ideas from our powerful and popular TX Series PA systems, the limiters used in the input and crossover stages are a complex combination of gain reduction and sweeping filters. As the EF500P is being pushed to its maximum input / output levels, it's advanced filtering begins rolling off unnecessary subsonic frequencies. In addition the processing protects the individual components ensuring failure free operation even after long term operation at close to maximum output levels. The filter has remarkable (less than 70ms) response times, allowing the system to constantly be retuning itself to make sure the output is as clean, as loud and as clear as possible at any given moment. This is achieved without negatively affecting the overall sonic quality of the cabinet. This ensures that the essential part of any mix, like the vocals or solo instruments, come out clean and clear when the cabinet is being operated at the extremes of power and woofer excursion. Extremely fast and accurate limiting is in place to protect the speaker components.

The EF500P has a built in mixer allows the loudspeaker to be used directly with a microphone and / or line source. The loop output allows additional active cabinets to be driven from one cabinet's mixer stage, or a series of cabinets to be driven from one source. If desired, the end user can combine a pair of the EF500P's using the mixer inputs on each cabinet and coupling the loop outputs. In this simple example you would have the ideal presentation system with two microphone inputs, two line inputs optimized for CD, Cassette or laptop computer audio source, complete within two speaker cabinets. Many of our active cabinets can be linked together but a maximum of three 'mixers' can be active at any one time. (Making three mic sources and six line sources available in any three or more cabinet array). The microphone input has equalization and high pass filtering appropriate for vocal applications. The trim control allows looped cabinets to be individually adjusted in level. This is invaluable in applications where large numbers of cabinets are used such as clusters or in trade show applications or when EF500P's are used as repeater cabinets or for side fill. The 100 Hz high pass filters allows the EF500P to be used more efficiently with any active subwoofer.

Úlite Series Overview
The Compact & Complete Solution Yorkville’s Úlite 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, Úlite systems are among the most advanced, most versatile and most efficient high powered portable P.A. boxes available.

New models for a new millennium
Since the mid 80’s, the Úlite series has grown from the original compact M-160, into a complete line of professional enclosures including active and passive full-range cabinets, stage monitors and subwoofers.

Today’s Úlites, 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.

A new concept in loudspeaker cabinet design first seen in Yorkville’s Pulse TM352 and TM12 is perfected in the Úlite line. Ideal for any small PA rental house, installer or sound company, these loudspeakers may replace a number of specific application cabinets in any inventory.

Modified Trapezoidal Shape 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 Úlite 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 Úlite 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 Úlite 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 Úlite 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 Crossover Networks and Protection Schemes
The majority of the Úlite 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 Úlite 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.

Under the hood of an E152 The L-Series uses our MSP™ (Multi-Sensing) protection system. This sophisticated and accurate protection network covers all the bases. Components are protected from excess subsonic energy, as well as short term (20ms) and long term (500ms) overpowering. This combination accurately protects against mechanical and thermal failure. In addition the high frequency driver is transparently and reliably protected by borrowing the light bulb from our CTL™ protection scheme and combining it with a relay (to further protect the light bulb). This self resetting protection scheme accurately senses clear abuse to any band, and shuts the band down until the potentially damaging situation is resolved. Bright indicator LED's (one for LF, one for MF/HF) are provided on the crossover dish to warn the user of impending / active shutdown. Along with the protection scheme, the L-Series crossover also incorporates 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.
Úlite Series Characteristics
Processor Controlled
Full 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 Úlite system is always tuned and ready.

Rugged Driver Mounting System
All Úlite 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.

E2152 Cutaway ImageRugged Black Carpet Covering
The stylish yet practical carpet that covers the Úlite cabinets keeps them looking great. The two part rubberized glue that is used to attach the carpet ensures that Úlite 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 Úlite 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.
