About the CA1 Control
The Audio by Van Alstine CA1 Control Amplifier is an all-analog integrated control amplifier using the company’s Advanced Nested Architecture (ANA). It combines a line-level preamplifier, moving-magnet phono stage, power amplifier, and headphone amplifier in one chassis. The amplifier provides three line-level stereo inputs plus one MM phono input, remote power/volume/mute control, a 12V trigger output, a 1/4-inch headphone jack, and heavy-duty 5-way speaker binding posts. It uses a linear power supply with a high-capacity toroidal transformer and is designed for nominal 4-ohm speaker loads and higher. The manufacturer’s product page and catalog listings indicate that the CA1 Control remains an active product rather than a discontinued model.
