Vision SLR Preamplifier

The Vision SLR preamplifier has our best-ever solid-state preamp circuits in a stunning fully remote controlled chassis. The Vision SLR preamplifier takes solid-state preamplifiers to a new level of musicality and user convenience. It has remote controlled power, volume, mute, input switching, and panel dimming. A lovely silver faceplate is standard, along with premium RCA jacks and a low-distortion headphone amplifier. The Vision SLR preamp has all of the transparency, dynamic range, linearity and pure music for which Audio by Van Alstine is known. Listen to all of your recordings again and you will hear acoustic space and musical nuance in a much more real and involving way. Line Stage At the heart of the Vision SLR's line stage are discrete, solid-state class A audio circuits. These circuits are crazy fast, enormously linear, and outrageously musical. They employ matched JFET input transistors driving a class A output stage, using a "simple as possible but no simpler" design philosophy. The result is a level of resolution throughout the audio spectrum that we have not been able to achieve with any IC opamp, regardless of price. Even with the extra effort to provide true discrete audio circuits to achieve our musical goals, the cost is much lower than you would expect, especially given the level of performance. Power Supply The Vision SLR's linear power supply features a toroid power transformer feeding a full wave bridge rectifier and large smoothing capacitors. This is actively regulated down to plus and minus 15 volts and followed by more large smoothing capacitors and extensive RF decoupling. SLR Chassis Design The SLR chassis features a precision remote control volume control along with five sets of remote switchable inputs and two sets of line audio outputs. Additional functions include: A precision balance control. Mono/Stereo - to get mono audio sources (such as older TV and other video sources) to both left and right channels and to quiet noisy FM broadcast and old records. Low Gain - to allow better volume control use with the high-efficiency speakers and high gain amplifiers. High Filter - to tame excess brightness from low quality sources. Low Filter - to deal with warped records and turntable rumble. Support for tape monitoring. A built-in high quality headphone amplifier. The 1/4" sculpted aluminum face plate is finished with our incredibly durable double-anodized process is standard. All RCA jacks are premium quality, gold plated, heavy duty parts. A removable IEC power cord is standard as well. Dimensions: 17" wide x 12" deep x 3.5" high. Shipping weight is 17 pounds.
