Product Detail

Specification:

IC board is brand new original authentic，This product is welded, tested good finished board. This circuit is a channel without a rectifier circuit, if you want stereo, please buy two pieces.

Power supply: 15V AC double to 28V (AC needs rectification filter) or ± 18V dc to 40V. Recommended dual 35V, 35V transformer attention not double, plus or minus 35V DC (recommended dual 26V / 200W or more toroidal transformer, the transformer output must be three lines, such as:

26V-0-26V, (referred to as dual 26V) dual DC rectified voltage of about 35V), the transformer output is two lines or four lines is not possible.

Reminder: the battery can be used! (Must be connected in series battery).

Transformer power: Minimum 200w, multi-channel power is calculated separately to note that the better must be truly full power transformer

Output Power: Maximum power output 170W, than the rated power, output power and output transformers and speaker proportional

Load: 6-8 impedance around Europe 100w-150w box is very suitable, we must choose a good speaker problem

Board dimensions: length 70mm width 35mm height 25mm <height of containing the chip installed height>

Weight: 40g (5g within error).

Audible Noise: None

The board without any noise, the premise is to deal with the ground and the level audio to the noise

Midpoint voltage: less than 5mV

BTL perfect support multiple board connection

Board are pure amplification stage

Board only supports DC input rectifier filter section without a friend in need can additionally choose

We must ensure that the positive and negative at the same time and the positive and negative supply voltage error can not exceed 1v.

Integrated chip TDA7293 must be insulated from the heat sink a hundred percent.

Package included:

1PC x TDA7293 Dual Parallel 170W Mono Power Amplifier Board Assembled
