Read Instructions:

The Owner’s Manual should be read and
understood before operation of your unit. Please, save these instruc­tions for future reference and heed all warnings.

Clean only with dry cloth.

Packaging: Keep the box and packaging materials, in case the unit

needs to be returned for service.

Warning: To reduce the risk or fire or electric shock, do not expose

this apparatus to rain or moisture.

Do not use this apparatus near water!

Warning: When using electric products, basic precautions should

always be followed, including the following:

Power Sources

Your unit should be connected to a power source only of the voltage specified in the
owners manual or as marked on the unit. This unit has a polarized plug. Do not use
with an extension cord or receptacle unless the plug can be fully inserted. Precau­tions should be taken so that the grounding scheme on the unit is not defeated.

Hazards

Do not place this product on an unstable cart, stand, tripod, bracket or table. The
product may fall, causing serious personal injury and serious damage to the product.
Use only with cart, stand, tripod, bracket, or table recommended by the manufacturer
or sold with the product. Follow the manufacturer’s instructions when installing the
product and use mounting accessories recommended by the manufacturer.

The apparatus should not be exposed to dripping or splashing water; no objects

filled with liquids should be placed on the apparatus.

Te rminals marked with the “lightning bolt” are hazardous live; the external wiring
connected to these terminals require installation by an instructed person or the use of
ready made leads or cords.

Ensure that proper ventilation is provided around the appliance. Do not install near
any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.

No naked flame sources, such as lighted candles, should be placed on the apparatus.

Power Cord

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong. The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet. The AC supply cord should be routed so that it is unlikely that it will be
damaged. If the AC supply cord is damaged DO NOT OPERAT E THE UNIT.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Service

The unit should be serviced only by qualified service personnel.

Introduction

The Unity™ U15P is a premium quality 3-way, tri-amped, pow­ered 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 cre­ative 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 ac­curate 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 ampli­fier 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 mod­ules 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 technolo­gies. 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 func­tion with speaker level signals.

1. U15P Level Control

The Level control on the U15P adjusts the
amount of volume added to the sound sys­tem. 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 there­fore 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 cor­rect 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.

Delay Settings

High pass frequency response (100 Hz – 20
kHz). Use when the delay of the subwoofer
is 2 ms. The UCS1P and UCS1 use this setting.
A 2ms delay is roughly the same as pushing
the U15P back by roughly 27 inches (68 cm).

Setting 3 – 3 ms Delay

High pass frequency response (100 Hz – 20
kHz). Use when the delay of the subwoofer
is 3 ms. The LS800P, LS808, LS1004 and TX9S
use this setting. A 3 ms delay is roughly the
same as pushing the U15P back by roughly

40.5 inches (102 cm).

Setting 4 – 8ms Delay

High pass frequency response (100 Hz – 20
kHz). Use when the delay of the subwoofer
is 8ms. The LS1208 uses this setting. An 8 ms
delay is roughly the same as pushing the
U15P back by roughly 107 inches (273cm).

3. LINK Jacks

The Link jacks are set up to make it easy to
hook up the Unity™ U15P to any audio sys­tem with a minimum of hassles. All of the Link

jacks are connected in parallel, so you can
use any of them to daisy-chain other U15Ps
or powered subwoofers. For normal operation
connect the Unity™ U15P just like an ordinary
powered speaker.

The Unity™ U15P may be plugged in be­fore or after other enclosures, such as pow­ered subwoofers. The U15P does not alter
the signal to the daisy-chained enclosures
and will not draw any power from the host
mixer/processor driving them. Also, note that
an external crossover is not necessary when
using the Unity™ U15P.

As well as accommodating full range
enclosures, the Link jacks allow many U15Ps
to be connected in a string (parallel). There is
no practical limit to the number of U15Ps that
may be connected together.

4. Protection

The U15P has circuitry to prevent clipping,
over current from the power amplifier and
over excursion of the speaker. At high levels,
the limiter will limit the gain of the Unity™
U15P and hence, if the user attempts to set
the level control at a higher level than origi­nally set; the resulting setting will be incorrect.
The level control should be set while operat­ing at low levels (under 10 watts).

If the level control is set too high due to set­ting it at high operating levels the input circuit
will clip and the dynamics of the bass will be
lost. The Red Clip indicator will signify when this
occurs. This can happen without audible distor­tion since the filters will filter out the distortion.
