KI home theatre system has plenty of power to give and the right digital sound processing to simulate multi-point surround sound. The Sony MU. It may be large to the point of excess, but this lets the MU.
KI handle any audio thrown at it.
Good virtual surround processing and an abundance of power means the MU. KI home theatre system is well suited to large rooms and blockbuster movies. KI HT-DDW has two imposing floor-standing speakers, two squat subwoofers, a centre speaker and four satellite surround speakers. Each speaker can handle a maximum W, while the two subwoofers are rated to withstand W.
Add all this up, and you get a total power output of W. To put it into perspective, the two pre-built home theatre systems we tested before the MU.
We thought that these were more than powerful enough for use in medium and large rooms, so the extra power of the Sony MU. Of course, this fits in with the MU. It does have a sense of quality to it, though. The receiver and amplifier are solidly constructed and the speakers are heavy.

Features Built for action movies and party music, the HTM7 makes a statement whether it?? With minimal controls on the receiver, all you have to do is select the source, how you want to hear it and turn it up loud. The 2 subwoofers will ensure you feel.
Built for action movies and party music, the HTM7 makes a statement whether it??When it comes to the Sony electronics you own, there are a lot of intricate parts that can break down or wear out. On Sony televisions, a blackened or fuzzy screen can be caused by a transistor or diode on the control board that has burned out, loose internal connections or a rear input line that has become loose. Audio equipment like the receiver can also suffer from internal electronics failure and frayed wires.
DVD players and video projectors can also exhibit part malfunctions. Once you have determined the issue that is affecting your piece of Sony equipment, the next step is to make repairs with certified genuine replacement parts, like those that we offer at Sears PartsDirect.
When you have diagnosed the problem with your Sony entertainment equipment and figured out what you need to repair it, you can find the part at Sears PartsDirect.

Aloha Housewares. American Harvest. American Sports. American SportWorks.The purpose of the protect error is to protect the amplifier components from damage should a short circuit occur. The most common form of short is usually user error when they short the speaker terminals, or overload it by attaching too many speakers.
The protection mechanism usually places the amplifier into protect mode when it detects a short, and during this time it prevents power to the amplifier circuitry, thereby preventing harm to the speakers and expensive amplifier components.

When you see this message, the first thing to do is to switch OFF the amplifier immediately, and disconnect the speakers from the terminals, at the amplifier end. Let the amplifier cool for 15 minutes and then switch ON to see if the message still appears. If the message goes away, then you need to make sure the speakers are not short and correct impedance.
However if the protect message keeps appearing all the time and without the speakers attached, then it is likely that there has been permanent damage to the internal components, and the unit will require repair.
How to Fix Sony Amplifier Protect Mode Error
This is a complex piece of Japanese electronic engineering and it requires a fully qualified and experienced electronic engineer to repair it, therefore do not attempt to repair it. In the following sections, we look at what sometimes goes wrong when such an error appears permanently.
If we look at one side of the push-pull stage, we see that if Q goes short between its collector and emitter junctions, the voltage rail would flow through the speaker and ground, however, there is R in the path, which will go open. When R is open and Q is short, Q will detect current through its base junction which starts the process of flagging the protect error.
Usually, a Class AB push-pull configuration has a ceramic resistor within the power path, which the Sony service manual calls non-flammable resistor that requires checking. When the transistors go short between their collector-emitter junctions, it creates a path from the positive voltage rail to ground -- or negative rail to ground, in a split voltage system -- and the only resistor in this path is this non-flammable resistor, which goes open.
In this channel example, the non-flammable power resistor is R which is a twin resistor package consisting of a pair of 0.
These are hardy transistors with collector current Ic rated at A. It would require a hard short across the speaker terminals in order to damage them. This together with a state-of-the-art Japanese electronic protection mechanism ensures that they will survive for many years. Amplifiers Donate. Author: Peter J.
