Last chance! With the release of our new CA1 Control Amplifier, the Vision SET 120 Control Amplifier is now a legacy product. However, we still have inventory of sheet metal and other parts for this popular amplifier, and we hope to make it available for as long as we have the parts to build them. But once our current inventory of parts is gone, there will be no more.

If you're interested in owning one of these classic amplifiers, order now before it's too late!

Our classic Vision SET 120 Control Amplifier combines the award-winning Vision SET 120 Power Amplifier with a passive "preamp" section to get you closer to the music than ever before. Just plug in your sources and enjoy. No separate preamplifier is required.

The Vision SET 120 Control Amplifier delivers all of the transparency, dynamic range, linearity and pure music for which Audio by Van Alstine is known. Listen to your recordings again and you will hear acoustic space and musical nuance in a much more real and involving way. The cost is lower and the performance much higher than you would expect.

Power Amplifier section

The SET name stands for this amplifier family's unique Single Ended Transistor voltage amplifier design, which is based on a simple but amazingly effective single-ended transistor topology. This is followed by a very fast and rugged class AB power MOSFET output stage. Our SET amplifiers are uniquely DC stable, which means they will not generate speaker damaging DC drift even when driven past clipping.

The Vision SET 120 Control Amplifier handles difficult speaker loads from 4 ohms and up and provides plenty of power for any rational loudspeaker. It runs cool and is amazingly fault tolerant. Because its "preamplifier" stage is passive, it is configured for 6dB higher gain than the Vision SET 120 Power Amplifier.

Speaker outputs are provided via one set of 5-way binding post speaker connections.

Passive "preamp "control section

The Vision SET 120 Control Amplifier's input section has four sets of line level inputs, a selector switch, and a precision passive volume control. The amplifier comes with an independent high-quality headphone driver, and the speakers can be turned off to use headphones alone.

If you need a phono section, we recommend our free-standing Vision Q+  phono preamplifier. Just plug it into one of the Vision SET 120 Control Amplifier's line level input sets.

Power Supply Circuits

The Vision SET 120 Control Amplifier has an oversized, high-capacity toroidal power transformer and multiple regulated power supplies for all areas of the amplifier, including the output transistors. This helps the amplifier provide incredible dynamic range, bass extension, transient detail, and air. All of the power supply parts are selected for long life, reliability and operate well within their technical specification ratings..

The Vision SET 120 Control Amplifier operates on standard 120 volt AC power, has an IEC power jack, and includes a polarized 120V power cord.

*Effective immediately, all Vision SET 120 control amplifiers will have a 15% restocking charge under the 30 day satisfaction guarantee.
