The D SERIES-PA3 is a high efficiency 3.5 W power amplifier with two line inputs and an amplified output to drive a 4 or 8 ohm speaker. The -PA3 features a balanced line level input that may be connected unbalanced. The gain range will accommodate standard unbalanced levels as well as professional balanced levels.

The amplifier features a stereo Mini-Jack input on the front panel. The input is designed to receive standard -10 dBV consumer level signals from sources such as a computer or personal media player. The left and right audio signals received on the Mini-Jack are summed to mono and amplified. When a source is connected, the rear-panel input is switched off. The amplified output level is controlled by a front-panel volume control.

A recessed slide switch on the side of the chassis is set during installation. This switch determines the sensitivity of the balanced rear-panel input.

Amplification is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation.

The D SERIES-PA3 is designed to be mounted in a wall box. The front panel does not include any illuminated indicators, making the -PA3 ideally suited to installation in dark rooms or areas. Wiring is connected through a rear-panel detachable terminal block. Module operation is from a 24 Vdc ground-referenced power supply.

Don't listen to the negative reviews. There is so much to love in this story.
Format: Paperback
First off, I would like to say that this is mostly for people who either A) bought vol1 and want to finish the story, and B) fans of not only Batman, but also the "legacy" that he has left behind him. More on that later. This is the second half of the weekly 26 week story revolving around The former robins, and deals heavily around The Spoiler, Cassandra Cain (batgirl) and Harper Row (bluebird) the main thing I have to say about this story is that it more effectively does what "batman eternal" and "Robin war" we're trying to accomplish. In batman eternal, the story was over 50 issues long, and there were so many times where the story was abysmal because of filler and boring events that made it feel like such a cash grab, and with Robin war, by the end of that story there is almost nothing important that happens, leaving you to feel like you could have went without reading it. Batman and robin eternal not only tells a captivating story, but with important enough events that justify your time and money put into this story. I can whole heartedly recommend this to ANY fan of not only Azrael (very important character in the 90s when knight fall was going on) but also Cassandra Cain (new batgirl up until 2011) and they in my opinion are the highlights of this story because of the justice they are given as comic book characters. We haven't seen them since in the new earth, so it's nice that they got some recognition before rebirth. Hopefully we see them more, but this is also a solid story for the robins as well, each of Batmans pupils gets justice at some point in the story, so I can say a fan of any of them will be pleased. I can say this especially as a Red Hood fan who longs for the day that Jason Tood will finally get a good/solo ongoing series. Now with that said, the art can be inconsistent seeing as how there are more than one of them, and the "big plot twist" shown in this second half can be pretty obvious that "there's more than meets the eye" with the situation, but I rather not give spoilers. Again This book is MORE THAN WORTH YOUR TIME AND MONEY if you Like ANY robin Like Scott Snyders "bluebird" Like the old ninja looking batgirl Like Azrael Like batman stories that don't have batman as the main focus

Great story by several great storytellers

Picks up where vol1 left off but generally feels more cohesive and organized. Great story by several great storytellers. Connects heavily with Grayson if you want more context.
