Realistic STA-111

Send

The STA-111 (Single Tube Annunciator) is a realistic model of a vactrol-based electronic circuit designed to produce the distinctive sound of electronic annunciators present in a variety of vintage synthesizers and studio equipment. This model is highly accurate and faithful to the original circuit, resulting in a rich and warm character suitable for a variety of electronic music producers, sound engineers, and synthesizers enthusiasts who value vintage sound aesthetics.Overall, this product offers a unique sonic flavor that bridges the gap between vintage and modern synthesis techniques, making it an essential addition to any studio setup looking for that elusive, authentic sound.Some of the key features of the STA-111 include:1. Vactrol-based circuit: The STA-111 employs a vactrol, a photoconductive device that uses a light-dependent resistor (LDR) to introduce time and squash character into audio signals. This technology is essential in creating the classic electronic annunciator sound.2. Low-noise design: The STA-111 implements low-noise design techniques to minimize unwanted electrical interference (EI) and noise, making it suitable for use in high-quality audio applications where such background noise is undesirable.3. Careful component selection: The STA-111 utilizes high-quality, vintage-style components similar to those in the original equipment, such as high-quality resistors, capacitors, and vactrols, to ensure authenticity and sonic character.4. Flexible control options: The STA-111 offers multiple control options, such as input level, threshold control, and output level, allowing users to fine-tune the annunciator's sensitivity and response to different signals.5. Robust construction: The STA-111 is housed in a rugged, anodized aluminum enclosure, which ensures durability and low susceptibility to electromagnetic interference (EMI), ensuring that the module can withstand heavy usage and harsh environmental conditions.Overall, the STA-111's realistic vactrol-based circuit, low-noise design, careful component selection, flexible control options, and robust construction make it an excellent choice for anyone looking for an authentic electronic annunciator sound in their studio or synthesis setup.
