IWISTAO HIFI Digital Amplifier 2.1 Amp 2x50W + 100W TPA3116D2 Subwoofer No including Power Adapter Whole Aluminum Casing Silver White
Model No: WHFDA-TPA3116
This HIFI amplifier uses two digital amplifier chips TPA3116D2 as core amp with small size, high efficiency, high power characteristics, one is for left and right channel power amplifier, and the other one is for subwoofer with a bridge driver. Its output power is up to 2X50W (for left and right channel) + 100W (for subwoofer), and its efficiency can reach 90% or above. Suitable for using notebook switching power supplies and 12V-24V battery powered directly ordinary and it is suitable as household and automotive amplifiers, easy to use, working voltage DC 12V-25V. All components used to use genuine components, is able to work for long-term stability. With a high signal to noise ratio, hardly to heard any hums.
The power adapter isn’t included; you can use the notebook power adapter. DC output plug dimension: inner -- " +", outside -- “--”; And Outside Diameter is 5.5mm, Inner Diameter is 2.2mm
1. Using HIFI components.
1). The total capacity up to capacitance 6800UF, so you can make a better signal to noise ratio, stronger intensity low frequency, and a steady stream of energy provided.
2). Input capacitors adopted stereo dedicated AUDIO one, so that there is a richer detail for performance.
3). Also, used red ring of low loss inductors, SMD chip parts and high-quality sealed potentiometers that produced by Taiwan.
4). Op amp is NE5532 and it fixed into gold-plated jack of Op amp, you can replace the OP IC based on your personal preference.
2. Optimize the design of a low-pass filter, stronger driving force to subwoofer.
3. Full-range output for left and right channel, it can drive 3-16 ohm speakers with a very wide range at rated voltage 24V state.
4. It can drive 2-16 ohm subwoofer at rated voltage 24V state, unique.
5. Bass gain adjusted independently.
6. Potentiometer features: left one in the middle is the stereo subwoofer volume control to adjust the volume. The right one is total volume adjustment.
1. Those customers buy a separated amplifier (without a power adapter), please confirm if your own power has better quality (mainly if the performance of power supply ripple is better), if adopted pool quality power supply, the noise may occurred. And recommended to buy the 19V6.5A supply in our store as below. Supply voltage range from 12 – 24 V DC, but also if this unit is adapted with low voltage and low power output, the sound is smaller.
2. Do not use cheap audio signal cables, which are not shielded itself, and will introduce high-frequency noises, when potentiometer rotation along, the noises greater becomes larger. There is good signal cable but not too expensive, such as Chosel, when used it, the amplifier is quiet as the deep sea, without the slightest hum.
1. Output power: 2X50W + 100W Subwoofer
2. THD + N: <0.1% (1 KHz, 25W)
3. S / N Ratio :> 102dB
4. Working voltage: DC12-25V
5. Power DC plug Specifications:
DC output plug dimension: inner -- " +", outside -- “ -”; And Outside Diameter is 5.5mm, Inner Diameter is 2.2mm
6. Without external power supply, you can use the laptop power supply.
7. Dimensions (L * W * H): 120mm * 103mm x50mm
8. Weight: 0.5kg
9. Color: silver white
1. Keep this amplifier to connect the power adapter, and then plug the power adapter is connected to 220V power supply, so you can put an end to avoid the impact and power switched ignition spark. Wrong way is power adapter to connect to AC 220V first and go to connect the digital amplifier.
2. It is represent powered access when LED lamp is on.
3. DC19V power supply will be better than DC 12V one, its dynamic is better than DC12V.
