Aphex Model 124A Amplifier Accessory by Aphex. $249.00. The Aphex Model 124A Audio Level Interface is designed to allow use of -10dBV consumer hi-fi equipment with +4 or +8dBm professional / industrial / broadcast audio systems. It provides an extremely clean, reliable two-way buffer so both systems can operate at maximum performance levels, matching impedances and operating levels. INPUT Servo-balancing means that high common mode voltages, such as induced hum fro...

Mic pre-amp circuit using ic 4558 is a series of mic amplifier based on ic 4558 and also could use other op-amp ic ie TL072 / TL082 / NE5532. And a transistor C945 as a buffer circuit and other components of resistors and capacitors. See circuit schematic of mic pre amplifier :
