The ACV-NOS Edition is 100% analog and utilizes over 350 carefully selected components including premium audio-grade op amps and high-tolerance, non-microphonic capacitors to guarantee high performance, temperature & voltage stability, low noise, and maximum headroom. <\/p>\n
Asheville began with a classic chorus architecture using a 1024 stage New Old Stock Matsushita (Panasonic) BBD and a step-up boost power supply for maximum headroom. They then implemented a vintage-style compander with emphasis\/de-emphasis coupled with discrete transistor, 5th-order, anti-aliasing and reconstruction filters to maximize the range of delay times without undesirable artifacts. The feedback circuit uses a synthesizer-style VCA to provide a classic, warm regeneration tone while offering an accurate method of dialing in the perfect amount of musical peaks and notches. <\/p>\n
The input preamplifier includes a discrete, high impedance, JFET stage that can also be used as an always-on buffer. Asheville also included some soft limiting to provide character with hot signals and prevent transients from overloading the delay section. <\/p>\n
The clock, modulation, oscillator, and even the switch logic are all fully analog. The clock VCO includes a temperature-compensated exponential converter for a wide, even range modulation. The clock drives the BBD at extremely high current to eliminate artifacts and provide a clear, tight sound with consistent gain. An assignable expression input increases the flexibility and control available to the user. <\/p>\n
Power and grounding deserve special attention. The ACV-NOS is designed using a multi-layer PCB with dedicated split power and ground planes for low noise and crosstalk. The power input is fully protected from reverse polarity, over-voltage conditions, and ESD spikes. Our custom-designed 9V to 15V power supply works conveniently with standard 9V pedal power supplies, and eliminates sources of noise and radio frequency interference (RFI\/EMI). Its boost technology runs at MHz frequencies to eliminate artifacts usually associated with simpler charge pump or older style converters. <\/p>\n","protected":false},"excerpt":{"rendered":"
