Ampmix

4-channel mixer/attenuator with 2.0x gain and 5V offset

• 4-channel amplifying high precision mixer/attenuator.
• works as 4 channel mixer, 1 attenuator + 3 channel mixer, 2 attenuators + 2 channel mixer or 4 attenuators.
• 2.0x gain (6dB) per channel, channels can be chained for greater gain, any combination of channels in any order. (16x gain, 24dB)
• 5.0V offset per channel.
• All analogue circuitry.
• hi-fidelity signal chain with low noise opamps.
• high impedance inputs and buffered outputs.
• slim 8HP footprint.
• compact 35mm Depth (with power cable attached).
• low power draw: 22mA +12V / 22mA -12V / no +5V required.
• Works for audio as well as CV.
• Fast responding CV inputs allow for complex modulation and modulating with audio signals.
• sum mix output.
• ch1 output normalized to ch2 input for patching convenience.
