Aphex Model 124A 2-Channel Audio Level Interface
Aphex Model 124A 2-Channel Audio Level Interface
The Aphex 10/4 Audio Level Interface, Model 124, is a dual, bi-directional buffer amplifier designed to provide level and impedance matching between consumer hi-fi equipment and professional, as well as industrial, audio system. Many consumer electronic devices can be very useful in the professional environment, but interconnection is difficult due to difference in operating levels, impedances, and unbalanced line operation. The Model 124 solves these problems through its simple, high-quality interface design without the added noise, distortion and instability that can result from an improper hookup.
