The Issue 3, 1971 edition of The Audio Amateur (Volume II, Number 3) takes you inside the cutting-edge labs of Advent and provides the blueprints for advanced quadraphonic recording. Here are the highlights to entice your inner audio engineer:
- Conversation with Henry Kloss: Step inside the mind of an audio legend. In this extensive interview, Henry Kloss discusses his "missionary zeal" for better ideas, the hidden potential of the cassette, and why he believes four-channel sound is the most exciting frontier for the home experimenter.
- The Quadpod D: Capture the "three-dimensional miracle" of live music. Build this high-performance four-channel microphone preamp and encoder, allowing you to record spatial audio and encode it for playback through standard matrixed systems .
- Kit Report: Heathkit IM-16 Voltmeter: Is it time to upgrade your workbench? This in-depth evaluation puts Heath’s solid-state voltmeter to the test, weighing the benefits of its "0.5V" extra sensitivity against the traditional reliability of tube-type meters.
- Two-tracking Trains: Join a field recording "eccentric" on a mission to preserve the vanishing sounds of steam and diesel locomotives. Learn the professional techniques required to capture high-fidelity transients in the challenging outdoors.
- Learning to Use Transistors: Master the "Diodes in Thousand." This technical installment explains the physics of the p-n junction and provides the essential theory needed to design stable, noise-free power rectifiers and reference circuits .
- Tapeniques: Quadraphonic Recording: Bring the concert hall home. James Jobson breaks down three professional methods for recording live quadraphonic sound, including how to utilize matrixed encoders for stunning "surround" realism.
- Tips & Technique: This issue is packed with DIY ingenuity, featuring a stepped tone control modification for the Dynaco PAT-4, a professional-grade record cleaning method, and essential stability fixes for AR-3a and AR-2 speakers .
