Sharp HT-SB400 - Features and Operation

By Danny Phillips



Our Score:


Inside the soundbar is an array of eight speaker drivers – two full-range for the front, two midrange drivers for the centre and four neodymium woofers. The 32W total power output includes 2 x 5W for the front pair, 2 x 3.5W for the centre channels and 4 x 3.75W for the woofers. The pre-out socket allows you to compliment these with deeper bass from an active subwoofer.

Another of the HT-SB400’s features is SRS WOW HD sound processing designed to boost the clarity and dynamism of the sound output as well as adding a surround sound effect. The drivers use High Definition Sound Standard technology, which is supposed to eliminate distortion and deliver what its creators describe as a 'smooth, layered sound with a pure tone'.

There’s a range of TruSurround HD sound modes designed for different types of TV programme – News, which places a little more emphasis on the speech frequencies; Cinema/Game, which adds extra bass depth; Sport, which appears to widen out the sound to bring out the atmosphere of crowd noises; plus a Standard mode.

These are complemented by a surprisingly flexible range of audio adjustments, allowing you to tailor the sound to your liking. There are bass and treble settings (-5 up to +5 in both cases) as well as subwoofer level and centre speaker level settings.

All of these tweaks are controlled using a credit card remote, which sports some rather small buttons but it’s fairly simple to use. A single button lets you switch between the two inputs and there are individual controls for the subwoofer/centre volume levels, plus each listening mode has its own button and you can control certain Sharp TVs using the bank of buttons at the bottom.

Good review, but a couple of questions hopefully someone can help me with.

1. Will the system auto standby or similar, ie can i leave it on all the time and it will only wake up when it detects audio from the TV.

2. How is this a 3.1 system when it only has a stereo input. I accept that it can filter out the sub frequencies but without more inputs / decoding it can only really be described as 2.1.

@GearGeek - I would imagine that the TrueSurround SRS tech includes some processing for a centre channel, as described in the review. There must be three physical speaker channels? Unsure on the .1, but either they can claim this as there are some sort of drivers outputting bass, or it's pointing towards the sub pre-out.

@GearGeek As an owner of the original soundbar, which does have auto standby, I would assume the new one does.
