Alfa Rpar - AS3365D - Multi functional VCA blocks (Fader/Panner)
Product number:
103129SO16
Product information "Alfa Rpar - AS3365D - Multi functional VCA blocks (Fader/Panner)"
AS3365 contains three VCA blocks, which are intended for use in musical synthesizer applications (VCA blocks, faders, panners, multiplexers, ring modulators etc.). VCA1 and VCA2 implement function of controlling amplification. A direct signal CVMix1 is supplied to the VCA1 control, an inverted CVMix2 signal is supplied to the VCA2 control. Using two amplifiers VCA1 and VCA2 together, you can implement the function of stereo panning of the input signal. Additional control input Vcntrl controls attenuation of output current - thus realizing function of double multiplication input signal on two control signals. VCA3 block has additional feature – possibility of control/mixing of two input signals.
Vast opportunities in designing new synth solutions:
♦ panner and crossfader designs can use the same single CV signal, because the CV input on VCA2 works in the inverse direction of the CV input on VCA1;
♦ possibility to use the four-quadrant VCA3 to generate a correction curve for equal loudness (RMS) panning and fading;
♦ voltage controlled processing and inversion of control voltage signals, like envelope and LFO signals;
♦ when signal inputs are DC-coupled then both audio signals and low frequency modulation CV signals can be processed with the same circuit;
♦ normalization on audio input and output connectors can switch between a panning or a crossfading function, depending on how signals are plugged in.
Features:
• “Linear replacement” – “pin compatible” to AS2164
• Exceptionally low control feedthrough without trimming: 10mV maximum out of 10 V.P.P. output
• Low noise: -110 dB typical
• Summing node signal Inputs
• Current outputs capable of swinging to within 1,5V of each supply
• Control voltages referenced to ground
• Wide supply range: ±3 to ±12V or +15, - 3 to - 9 V
Applications:
• Voltage controlled mixing for audio mixers and music synthesizers: crossfading, panning, ring modulation, stereo panning, audio switching, control signal processing, audio compression with side-chain function, etc.
• for electronic music

Safety Instructions for Electronic and Mechanical Components
Intended Use:
• Electronic components, including potentiometers, knobs, switches, connectors, resistors, capacitors or integrated circuits (ICs), are designed for use in electronic circuits and devices.
• Use these components only for their intended purposes in electrical and electronic applications, according to their specified voltage, current, and environmental conditions.
• Any use outside the intended applications may result in malfunction or safety risks.
Handling and Installation
Installation:
• Handle electronic components with appropriate tools, such as tweezers, to avoid physical damage or exposure to electric shock.
• Ensure that the components are installed in the correct orientation and according to manufacturer specifications to avoid malfunction or damage to the circuit.
Storage:
• Store components in a dry, cool, and static-free environment to avoid damage from moisture, extreme temperatures, or electrostatic discharge (ESD).
• Avoid direct exposure to sunlight, which could affect component stability and performance.
Protection from Static Electricity:
• Use antistatic equipment (e.g., wrist straps, ESD mats) when handling electronic components to prevent electrostatic discharge, which can damage sensitive devices like ICs.
Compatibility:
• Make sure electronic components are compatible with the circuit in terms of voltage, current, and other technical specifications.
Warnings
Electrical Shock Hazard:
• Some components can retain charge even when disconnected. Use appropriate tools and take precautions when handling components to minimize the risk of electric shock.
Burn or Fire Risk:
• Overloading or misusing electronic components may result in overheating, which could lead to burning or fires. Ensure that components are used within their specified voltage and current ratings.
Danger from Misuse:
• Incorrect handling or use outside specified limits can damage the components or affect the performance and functionality of connected devices. Only use components within their specified tolerances and conditions.
Choking Hazard:
• Small electronic components can pose a choking hazard if swallowed. Keep components out of reach of children.
