INTRODUCTION: PL2A OVERVIEW

Thank you for the purchase of your new POWERLIGHT 2A amplifier. To get the most out of your amplifier, review this manual carefully. The installation and operation sections provide proper connection and operation guidelines.

The POWERLIGHT 2A expands upon the features of the POWERLIGHT 2. The flexibility, user-friendliness and reliability of this amplifier will make it a valuable part of your system for years to come.

The POWERLIGHT 2A was designed to fit your system. You can adjust the input sensitivity to match the output capability of your mixing board. DataPort input signals can be summed before or after internal processing so that conflicts with external processing are avoided. The 4th order Linkwitz-Riley crossover has independent adjustment of crossover frequency and defeatable low-pass delay time. The high-pass side of the crossover includes separate binary adjustments for trim and driver EQ. The precision limiters provide separate adjustment of limiter threshold, peak mode and attack/release times. You can adjust the limiter threshold between 100% and 3% of available power. The limiters have a gentle limiting knee which preserves a sense of signal dynamics. In bi-amplified systems, a slower attack/release time can be used on the low frequency channel. The limiters can also be connected together to maintain stereo balance in full range mode or frequency balance in bi-amplified mode. A peak limiting mode with a fast attack time provides protection for fragile high frequency drivers.

The POWERLIGHT 2A is easy to use. All operating mode switches are grouped together on the rear panel. These critical switches have color-coded LED’s to positively confirm switch position. A brilliant blue LED on the front clearly indicates when the amplifier is in bi-amp mode. Limiter threshold, high-pass trim (HF ATTEN) and high-pass EQ (HORN BOOST) levels use combinations of two position switches for easy adjustment. These less used switches are located on the side panel.

The POWERLIGHT 2A is built for the long haul. Rubber-isolated XLR input connectors reduce stress on the contact pins and provide a tight, noise-free connection. All signal processing is done in side loops and then returned to the main signal path. This maintains high signal fidelity and provides a more robust system in the unlikely event a processor ceases to function.

Your new POWERLIGHT 2A amplifier will give you many years of great sound. The POWERLIGHT 2A is the most flexible, durable and best performing amplifier you can buy.
