The Circuit Slices CS030 module is a quality, low-noise, audio and CV mixer for the Eurorack synthesizer format sold at an affordable price.

Specifications for the CS030 Mixer
Five inputs with attenuators (inputs 1 – 5)
One input with a fixed, unity gain (input 6)
One line-level output (LINE)
One synthesizer-level output (OUT)
Selectable AC or DC coupled output
Able to mix AC and DC input signals up to +/- 10V
Selectable linear or logarithmic (audio) response for each attenuator
Output offset voltage factory-set to zero
Line-level output user adjustable
High-quality audio amplifier chip (OPA1662 or equivalent) with:

     Low noise level: 3.3nV/  @ 1kHz
     Ultra-low distortion: 0.00006%
LED indicates output level (Output > 2V dim green; ≥ 5V bright green; >7V to 10V orange / red)
Power: +12VDC @ 7mA, -12DC @ 5mA
Input impedances: 100K
Depth: 33 mm (1.3”) with power cable plugged in
Panel width: 8 HP

Features for the CS030 Mixer
High-quality, yet affordable Eurorack audio & CV mixer
Selectable logarithmic or linear response for each potentiometer
Zero DC offset -- critical for mixing pitch-control voltages
Low power consumption
Low noise using audio-quality amplifier chip
Reverse power protection
Modern SMT manufacture and single PCB design makes the module very affordable
Very small depth -- great for use in “skiff” cases
Includes power cable, case screws, and shorting jumpers
