Trouble Shooting

Video Picture
◆Trouble: None image or vague picture on display.
●Possible Cause:
○The set video output mode of DVD player different from the video signal mode from Receiver, for example, DVD player showing ordinary output while the display using mode of line-by-line;
○The less quality of connecting cables will result as “no image” on display;
○Improper video signal input channel for display.

◆Trouble: No sound coming after Power-on or a sudden soundless during playing.
●Possible Cause:
○Audio input channel for amplifier’s is improperly selected, for example, an audio signal outputs from DVD player to amplifier, but the input channel on amplifier is DVD while it is CD selected on amplifier’s;
○Problem with signal cables, for example, an improper connection upon jacks between the DVD player and amplifier, and as a kind reminder that the an Output-area is for DVD player while an Input-area is for amplifier, or, problem with the signal cables’ connection because of badly connected between DVD player and amplifier;
○Problem with speaker cables, just like loosened or ruptured;
○The speaker anode connected with cathode and during a normal working or dynamical status of the speaker system, the amplifier will go an auto-stop because of the safe protection for speakers relatively reacted, so as to ensure no damage to the whole audio system.

◆Trouble: No surround sound while home theater system in working status.
●Possible Cause:
○The CD disc has no multi-channel format (please make sure that the DVD disc you are using is in an indeed format of DTS and DOLBY, for to make sure the sound effect you will get);
○Improper audio format selected (please be sure that you know clearly if the preset audio output of the DVD player wrongly chosen for to play your target stereo performance in the surround system);
○Play mode for amplifier incorrect (please take a note at the switch between CD playing performance and DVD home theater status, to make sure that you need different condition for to listen to HIFI music or enjoy movie scene);
d.Wrong cable connection (such as the loosened condition might take play upon speaker cables or audio cables).

Quality Differentiation regarding Speakers

Technical data such as frequency range, handling power, impedance and sensibility are always frequent items provided to end users.

1) Frequency range determines the re-production ability for speaker.

2) Handling power stands for the possible output energy and this is one of the important parameters when you plan to purchase amplifier. Usually a power of 200-watt already good enough for home use and no more necessity for too higher.

3) Impedance appears to be another important data while matching up with amplifier. It is recommended the same impedance for amplifier and speaker, so that while during the best loading level of amplifier, there will be a maximum non-distortion power provided; otherwise, the exact output power will be smaller than the named one and at that condition, there will be danger of over-load.

4) Sensibility counts a lot for your selection for amplifier. A bigger sensibility, a better pushing force but a harder and colder timbre gets as well as a louder noise gets; otherwise, a smaller one will be more difficult to push with but a relative more precise timbre and lower distortion in stead. Most of the monitor speaker for home use range between 86dB – 92dB.

1. Traditional experience of distinguishing a good quality or not through steps of “See by eyes, Weigh in hands, Knuckle by fingers and Discriminate from badge” will help.

1) To see by eyes regarding handicraft This being said, we can tell the grade and quality upper or lower directly from the first impression upon the appearance of speaker. Those which made from natural fine timber are the best of best, however the cost are relatively very expensive because the concept of environment-protection and lack-of-resources, high demand for technics and a long-term of production and etc.. Commonly talking, those good quality speakers are using a veneer layer as decorating and to be adhesive onto the MDF board, for example: those rare veneer categories such as rosewood, walnut and cheery wood and etc. are of quite a natural texture which appearing to be nice from vision and a smooth and comfortable feeling you can feel of. Especially the butterfly-texture veneered through the procedure of several times of the fine piano painting and such kind of speakers are to be respected as the refinement of mid-higher level speakers. Those using PVC adhesive can only be considered as medium level or even less, no matter most of them made with 18mm-25mm good quality MDF board.

2) To weigh in hands As a common sense within the audio field, connoisseur focus on quality while laypeople care weight relatively. Namely it is to be considered that good speaker uses fine MDF board in 18mm-25mm thick while high class flagship speaker uses super solid wood or multi-ply veneered and that is why it weighs heavier and usually about 40kg to 50kg per piece. But most of those mid-lower types are using some floppy flakeboard and undoubtedly those mimics and counterfeits even made with cheesy flakeboard, and that is why they weighing more lighter.

3) To knuckle by fingers Here we would like to introduce a simple way by knuckling. When you knuckle on each side the baffleplate of speaker cabinet, for kind of good there will be a deep and slight clear response from each side as well as a feeling of hardness and thickness from the timbers and that means there is one or several strengthened-block constructed inside for a better support, plus a reasonable and burly cabinet build and, quite some useful methods applied for preventing from a sound insulation and standing wave, all these clearly explain for the good quality of speaker cabinet, otherwise, the less quality for the above mentioned will occur for an unwelcome sound effect.

4) To discriminate from badge A well-known speaker brand pays high attention to its own image as well as its enterprise influence, that is why relatively a very normative and delicate standard for each item of specifications, enterprise name and place of origin and etc. Some upper-level models even use 24K golden plate with concavo-convex letters for to reject a sense of artwork. What’s more, you may also tell the fine quality by the matching paper of birth, production serial number and even the pair serial number and ID number etc. You can select freely and satisfactorily from products with the above mentioned items if the cost reasonable for you.
