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 |
