Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.

This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.
AMPLIFIER CONTROLS
LFE Level Control: Allows you to adjust the volume of the low-frequency effects/ subwoofer channel to suit your room acoustics or tastes. However, it only affects the LFE signal. If you are not using the LFE input, the LFE level control will not operate. Configuring Your Receiver: You should choose the �Large� or �Wide� option for the left- and right-front speakers so that full lowfrequency information will be sent to the S412P speakers. Make sure that you also configure your receiver for �Subwoofer On� or �LFE On.� In this case, the LFE/Subwoofer signal will consist only of the .1 (bass) channel. The LFE signal level can be adjusted by using the LFE level on the S412P amplifier panel. For initial setup, you should set the level controls on both speakers at minimum (full counterclockwise rotation). With 5.1 source material playing, advance the level controls on each speaker slowly until the desired amount of effects channel is present. This is a rather subjective adjustment and should be made using a variety of program materials. If you choose, you can use the �Small� or �Narrow� setting on your receiver. In this case, all of the information below 80Hz will be fed to the LFE/ Subwoofer input on the S412P. Now the level control operates throughout the entire bass spectrum below 80Hz, not just within the .1 channel portion. This configuration is generally unnecessary but, in certain room-placement conditions, it allows greater bass-level control. Power Switches: The main �Power� switch is simply marked �On� and �Off.� Turn this switch on to commence operation of the powered amplifier after you have plugged the power cord into an AC outlet. The second switch is labeled �On/Off� and has two positions. Placing the switch in the �Auto� position puts the amplifier in Standby mode. In this mode the speaker will be able to automatically sense an incoming signal, which will trigger it to turn fully on. The speaker will also automatically switch itself back into Standby mode after approximately 10 to 15 minutes have passed without its sensing a signal. We recommend that you leave this switch in the �Auto� position for most applications. If you will be away from home or not using your speakers for an extended period of time, you should turn the speakers off by using the main power switch. The Manual position will bypass the auto-sensing feature and leave the amplifier on until turned off with the main switch or returned to

auto sensing by choosing the auto position. LED Indicators: When your speaker is turned on but is not receiving a signal, the LEDs glow red to let you know that your speaker is plugged in. When the speaker is receiving a signal, the LEDs glow green. We have provided a convenient �Green �On� LED� switch on the back panel to allow you to shut off the front LEDs should they interfere with your enjoyment of a movie. This switch has no effect when the LEDs are in red mode.
