30 Watt Stereo Audio Amplifier

30 Watt Stereo Audio Amplifier Kit

by Galak Electronics
Part No. VG-501A
Shipping Weight: 0.9 ounces (26 grams)

Enhance your audio projects with this compact and economical audio amplifier solution. Incorporating state-of-the-art bridged technology, this amp delivers up to 30 watts and a wide dynamic range with booming lows and crystal clear highs. Comes standard with a 3.5 mm stereo jack and DC input jack.

The unassembled kit includes instructions (including schematic and parts placement) and all the components to build one complete 30 Watt Stereo Audio Amplifier. A soldering iron, solder and a pair of cutters are required for assembly. Power source and audio cables are not included.

FEATURES:

  • 15 Watts x 2 RMS power at 8 Ohms with a effective frequency response of 25 Hz-25 kHz.
  • Bridged outputs means higher power with lower supply voltages - will operate down to 6 VDC*.
  • High efficiency amplifier with an average power loss of only 35% at full output power.
  • Wide input supply voltage from 6 VDC to 18 VDC with a maximum supply current of 2.5A at 18 VDC.
  • Automatic "soft on" avoids damaging pops and clicks to speakers during power up.
  • Fully connectorized with speaker screw terminals, DC power input and stereo audio input.
      * To achieve maximum output power of 15W x 2 channels, a minumum of 16.5 VDC supply voltage is required. Current limited to 2 Amps per channel max.
        Total output power @ 6 VDC is 1.5 watts x 2 channels; Total output power @ 12 VDC is 8 watts x 2 channels.

       ** Included heatsink will dissipate 4W at 80C and allow 8W x 2 channels RMS. Higher output power achievable with larger heatsink or air circulation.

SPECIFICATIONS:

  • Supply Voltage: 6VDC to 18VDC @ 4 amps max
  • RMS Power: 15 watts x 2 @ 8 ohms with 16.5V supply (current limited to 2 amps per channel)
  • Frequency Response: 25 Hz - 25 kHz with less than 0.3% THD @ 5 watts per channel (< 1.5% THD @ 10 watts)
  • Input Connectors: Power In - 2.1mm barrel tip-positive and 2 solder pads; Audio in - 3.5mm stereo jack
  • Output Connectors: Left and right speakers out - screw terminals; 3.5mm spacing
  • Board Dimensions: 1.50" x 1.95" (3.8 cm x 5.0 cm)
  • Board Material: 0.062" (1.6 mm) FR-4, with green solder mask and top layer silk screen
  • Finished Weight: 0.9 ounces (26 grams)
