Sell HIGHT TO LOW ADAPTOR TD-22 CAR STEREO AUDIO RCA LINE-OUT SPEAKER LEVEL CONVERTER best price

Product Name: With delay active high to low converter High to low: Used to convert the high-level audio voltage output from the speaker into a low-level audio signal for input by other power amplifiers. Common "high-to-low" converters are broadly classified into passive and active. Passive high turn low does not need to receive the battery, high signal recently low signal out, in the middle is a few resistors. So to be precise, the passive high turn low should be called the attenuator. Active high to low requires battery power supply, through the amplifier circuit, the high signal into a low signal, it is a reduction of the audio amplifier, some active high turn down with volume adjustment is actually the principle of the power amplifier. In the sound system, it is not necessary to use high to low, only when the original car has no low frequency output, this time you can consider adding a high to low to solve this problem, but the ordinary high turn will lose a part. audio signal. This high-to-low with delay device, the role of the delay is to solve the sound of the boot "beep". With it, you don't have to buy a delay.           Features: Ordinary high-to-low and no delay function, so when installing the power amplifier or subwoofer, the control line of the power amplifier is usually connected to the ACC line, so that when the key is turned on, the amplifier will be opened regardless of whether the player is turned on or not. Power-on, and sometimes it will cause the power amplifier to produce a turbulent current impact sound. This product is operated by the player when the car horn has a signal, and the delay is 1 second to control the power amplifier to start. Not only can work with the host at the same time, but also eliminate current surge With this product, the power switch or subwoofer can be controlled by this product, that is, the player is turned on, and the amplifier is also turned on. If the player is turned off, the amplifier is also turned off. However, some of the original car players, in the off state, the player also displays the time, the product is recognized as the player's power-on state, can not play the player control switch, but by the key ACC control switch!
