ST-MX3 3 Channel Audio Mixer - Line input and output

Radio Design Labs - 3 Channel Audio Mixer - Line input and output



  • Mix Line‑Level Signals
  • Three Individually Adjustable Inputs
  • Add Additional Line Level Inputs to an Existing Mixer
  • Combine Signals of Different Level, Impedance or Balanced /Unbalanced Configuration
  • Isolation Between Input Signals
  • Low‑Noise and Low‑Distortion Performance
  • RDL® SupplyFlex™ Power Input Configuration

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.

Typical Performance:

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
