Assembled M3 Preamplifier Board HIFI + OPA2604 Preamp High Quality For Amplifier DIY
Product Details:
- High voltage design tailored specifically for OPA2604AP
- No regulated power supply design, AC rectifier filter for direct supply op amp
- Ultra-large capacity capacitor array filter to ensure that no power supply under the state of purity
- Positive and negative power supply using Wu-type filter, and further access to the most pure power
- Two brand-name signal output coupling capacitor (MUSE, Promise BP)
- PCB Size: 100x100mm
- Channels: 2
Package Included:
- 1 x M3 Preamplifier Board (Include OPA2604AP)
Note:
- This board is customized for the OPA2604AP (included).
- The operating voltage is relatively high, if you insert other amp without reducing the power, it will be damaged. Please note that!
- If you want to use other amps, it is suggested that transformer below dual 12v be used. Generally speaking, filter rectified DC voltage cannot be greater than the working voltage of the amplifier.
