This product does not contain the power supply, the shop has the power of 120W can be another shot, the following instructions. Power can also buy other stores can also be.
Direct control version: suitable for HIFI appreciation, simple and easy to use, performance
Full remote version Except forSuitable for HIFI appreciation, inDirect control version, the increase of the full remote control function, with a liquid crystal display interface, adding a front amplifier and a high bass adjustment function, an increase of 2 input options
24V 5A power ( can use the computer notebook power )
Speaking of many buyers in the evaluation, actual it is normal, the buyers reacted to the connected joints, joints spark, this is the wrong operation, normal use is connected joints, and re energized, thus avoiding the physical effects of the charge and discharge of a capacitor.
Chassis full aluminum alloy wire drawing process, not a number of thin aluminum skin of the box can be compared
TDA7498EPower is 160WX2 (limit state power supply =DC36V measurement) power is very strong (heat dissipation is not to enhance the case is not recommended to use). Can drive double 8 inch big box without pressure, the price isPrice is 178
The effect is better than the TPA3123 and 3120 of the BTL way better, more than TA2024 small power amplifier and the like 10W
Product is the whole machine, does not contain the power supply, the store has an independent power supply can be used to buy
Power amplifier outline size: 90 wide and 108 long 35 mm (direct control version)
Supply voltage: DC 16V to DC 32V (limit 36V, not recommended)
Amplifier gain 30 times can be removed from the front stage, because the high magnification, suggested equipped with ground good point of signal lines such that open big also very quiet, those 2-3 yuan AV cable with words, the influence of signal to noise than

TDA7498 a double bridge is connected with a load (BTL) class D audio amplifier chip, using a single power supply has the characteristics of small volume, high efficiency, high power, such as. TDA7498 chip with our board reasonable exquisite layout, and the collocation of all kinds of high-quality components. For example: custom digital power amplifier special high current inductor, Philips, Vishay, Sanyo high frequency and high temperature resistance and low fever capacitance, original SMD devices and so on. This power amplifier board circuit is simple and reliable. The power supply voltage (15V36VVoltage is recommended not to exceed 36V(peak), the maximum output 80Wx2 (peak), the calorific value is small, the efficiency can reach above 90%. Portable electronic products, which can be used for switching power supply, are suitable for battery or battery powered. TDA7498 amplifier board has the advantages of small volume, use and installation are very flexible and convenient, the components all use genuine parts, Curzon Ren work stably for a long time. Do household power amplifier and car amplifier is very suitable 
Working voltage: 15V-36V(suggested 18--30VSingle supply is not recommended for long-term use of 32-36V, because the switching power supply 36V, many are subject to municipal fluctuations, 220V jump to 230V, the power may rise to 40V, beyond the safe range, Regarding==========First introduced under theDirect control version======================    |
===========================The following is the full remote version=============
* front stage using the MITSUBISHI M62446 sound chip, can carry out the full remote control digital volume control, input selection control,High bass adjustmentcontrol
* equipped with liquid crystal display, easy to operate and observe
* the front for the OP275 amplification, with Jack, you can upgrade other OP, play better.
Use matters needing attention:
* power supply interface is 5.5 outside diameter, 2.1 in diameter, if the shell is installed, the proposed power supply plug connection
* input power input, 1 input, 2 is through the road, without the tone circuit, the 1 way is through the tone circuit, by the remote control of the high bass control
Infrared remote control function preservation and storage volume and the input gear, such as your boot is boot -30DB, you can remote control to 30dB where, press the buttons on the remote control to save, is can save, high bass state not memory function.
* remote control is compatible with other models used, some key press is invalid, such as MUTE and 6 channel control keys
The large knob is a compound knob, the left and right rotation control volume, press down can choose the input channel, very convenient
Very intuitive LCD display, man-machine conversation
Huge cooling period is the following is the TDA7498E chip, 4 red ring inductance standing aside
Here is the PCB picture of the machine, drying materials:
Input signal 2 is CD high fidelity stateinput, do not pass to the high bass circuit, high bass remote control to it is not controlled
Input signal 1 is AV home theater state input, over to the high bass circuit, high bass remote control on it
INPUT:Input selection, switch CD or AUX input
SAVE:Boot volume memory button, to be set to the volume of the value of the boot, press 1 SAVE can be
VOL- VOL+:Volume control
BASS:Bass control, press BASS, and then pressVOL- VOL+ can switch to high bass
TRE:highAudio control, pressTRE, and then pressVOL- VOL+ can switch to high bass
Other buttons for blank keys, no use, only to do backup
Dedicated audio input capacitor
