Introduction
The Unity™ U15P is a premium quality
The nature of the Unity™ horn required a cre- ative power amp solution to ensure optimum performance and efficiency. An integrated DSP drives the
The U15P uses a combination of optimal ampli- fier topographies to ensure reliability and superior loudspeaker performance. A
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
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
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.
