3 Line Input Mixer - Line Out

Radio Design Labs ST-MX3, 3 Line Input Mixer - Line Out   The ST-MX3 is a line-level mixer module in the STICK-ON Series of products. It provides audio mixing of three line-level inputs with individual input gain adjustments. The line-level output is capable of driving either high or low impedance, balanced or unbalanced loads. The ST-MX3 operates from floating or bipolar dc power. For installations with microphone level inputs, use the ST-UMX3 Universal Audio Mixer.   Inputs (3): 30 kΩ balanced or unbalanced bridging Input Level: -20 dBu to +18 dBu (for +4 dBu output) -24 dBu to +14 dBu (for 0 dBu output) Output: 400 Ω to drive low or high impedance balanced or unbalanced lines Output Level: +4 dBu nominal, (adjustable; unbalanced output 6 dB below balanced line level) THD+N: < 0.03% (10 Hz to 20 kHz) Frequency Response: 10 Hz to 20 kHz (+/- 0.5 dB) Noise : < -80 dB (all inputs @ 10 dB gain, referenced to +4 dBu) Headroom: 18 dB Gain (each input): -14 dB to +24 dB (adjustable) CMRR: > 50 dB (50 to 120 Hz) Power Requirement: GROUND-REFERENCED or FLOATING, 24 to 33 Vdc @ 55 mA Ambient Operating Environment: 0° C to 55° C
