Introduction

The Unity™ U15P is a premium quality 3-way, tri-amped, pow- ered enclosure with an integrated DSP controller. An essential component of a powerful sound reinforcement system, the Unity™U15P has been designed to be easy-to-setup while providing unrivaled clarity and imaging with the least amount of complication during setup. Building on the popularity of the original Unity™ U15,Yorkville’s next logical step was to design a powered, active version. The result is a DSP-driven 900-watt U15P with a 15 inch Low frequency driver and innovative Unity™ mid / high frequency horn.

The nature of the Unity™ horn required a cre- ative power amp solution to ensure optimum performance and efficiency. An integrated DSP drives the three-way internal crossover, time alignment, component protection, limiting and the overall cabinet EQ extremely accurately. The DSP controlled time-delayed output, for ac- curate subwoofer alignment, ensures the Unity™ U15P delivers maximum impact in systems where complex external processing isn’t the preferred set-up solution.

The U15P uses a combination of optimal ampli- fier topographies to ensure reliability and superior loudspeaker performance. A three-tier designed amplifier module delivers 600-watts to the 15 inch neodymium woofer. Two class A/B amplifier mod- ules deliver 150-watts to the Unity™horn assembly, which is comprised of a single 1.75 inch throat mid driver and three 5 inch ceramic mid drivers.

Configuration

The Unity™U15P can be used in several different configurations; a pair of U15Ps used as a small P.A., multiple U15Ps used for wider coverage and U15Ps with subwoofers, which would be best in large venues. The Unity™ U15P utilizes DSP technology with selectable time delays to help time-align the U15P with different subwoofer technolo- gies. When used in a setup where only one signal is provided to an enclosure, such as a mono system or stereo with more than one U15P, you should use one of the Link jacks to daisy-chain the U15ps.

The Unity™ U15P has been intended to operate primarily with line level signals and will not func- tion with speaker level signals.

1. U15P Level Control

The Level control on the U15P adjusts the amount of volume added to the sound sys- tem. This control also adjusts for the relative sensitivity of any companion enclosures and the overall frequency response. The level control should be set by while operating and listening at a medium level. Once the setting has been established, the level on the U15P should not be changed.

It is not recommended to set this control at high levels since the limiter may be engaged and there- fore corrupting the output level unnecessarily!

A setting of 12 o’clock (0dB) on the U15P Level control is the correct starting point when setting up a sound system. From there, adjustments can be made for the best sound. The 0 dB mark refers to the setting that will give full power when the line input is used and the input signal is at a level of 0 dBVU. A clip LED is provided next the level control to guide the user.

2. Program Select

The Program Select control enables the user to vary the time delay of the Unity™ U15P. The table on the back of the U15P is a map as to which delay setting is to be used for each model of Yorkville subwoofer.

Subwoofers manufactured by other companies should have a published 100Hz group delay value or the user will have to ascertain the cor- rect setting through measurement (or by ear). A properly aligned multi-cabinet P.A. should yield a flat frequency response.

Setting 1 – Stand Alone

Full range frequency response (45 Hz – 20 kHz). Use when the U15P is the only speaker in the P.A. The time delay should be set to 0 ms.
