(Silicon Chip Magazine April ’95) Designed by Altronics. This kit will amplify a microphone (low level signal) to a line level to connect into an amplifier. It features high performance with a balanced mic input as well as two auxiliary inputs which are all mixed. It can be configured to operate from either a single ended power supply (12V to 30V DC), or a split rail power supply (±15V to ±30V DC), making it ideal to build into any existing amplifier.
Important Note For Kit Buyers:
