B types: two - channel
Descriptions:
100%Brand New and High Quality
Using BB company "DRV134 chip design of Unbalance to Balance board, can match the differential input (balance input) of power amplifier board used, can also be used as a Dual channel power amplifier plate change BTL output using .The power part adopts the LM317 + LM337 adjustable regulated power supply, using 4PC only imported 3300 uf filter capacitor to ensure stable performance.
Working voltage: AC Dual 5v-16v
DC Dual 7v-24 v
The board size: 90 mm * 50 mm
Note: the board delivery has been debugged, the default Dual work around 12 v voltage, suitable for using double power supply 12 v transformer, if use other voltage transformer can be appropriate to adjust the output voltage of plate (to make positive and negative power regulating jumper cap off, lest voltage asymmetry burn DRV134 chips), generally use how many volt transformer, voltage into just how many volts is ok, adjust the test point: a pens connect GND, another pens connect jump line row needles.
Capacitor case changes, color is black
Packaging
1pcs*DRV134 Dual channel Unbalance to Balance Board For the Differential input amplifier board and BTL output Use
