3. Setup

3.1 Rack Mounting

The Stanton RM-50 is designed for standard 19-inch rack mounting. Secure the mixer using appropriate rack screws (not included) into a stable equipment rack. Ensure adequate ventilation around the unit to prevent overheating.

3.2 Audio Connections

  1. Input Sources: Connect your turntables to the PHONO inputs and CD players, media players, or other line-level devices to the LINE inputs on the rear panel. Ensure the corresponding LINE/PHONO switch on the front panel is set correctly for each channel.
  2. Microphones: Connect dynamic microphones to the MIC 1 (XLR) or MIC 2 (1/4" jack) inputs on the front panel.
  3. Master Output: Connect the balanced XLR MASTER OUT to your main amplifier or powered speakers.
  4. Booth Output: Connect the BOOTH OUT to your monitor speakers or a separate amplifier for booth monitoring.
  5. Headphones: Plug your headphones into the 1/4" HEADPHONE jack on the front panel.

3.3 Power Connection

Connect the provided power cord to the AC input on the rear of the mixer and then to a suitable power outlet. Ensure all connections are secure before powering on the unit.

4. Operating Instructions

4.1 Powering On/Off

Always ensure all volume controls (Master, Booth, Channel Faders) are set to their minimum position before powering on or off the mixer to prevent sudden loud noises or potential damage to speakers.

  • To Power On: Press the POWER switch located on the rear panel.
  • To Power Off: Press the POWER switch again.

4.2 Basic Mixing

  1. Input Selection: For each channel, select LINE or PHONO using the switch above the GAIN knob, corresponding to your connected source.
  2. Gain Adjustment: Adjust the GAIN knob for each active channel until the signal level is strong but not clipping (indicated by the channel's peak LED).
  3. Channel Faders: Slowly raise the channel fader for the desired audio source.
  4. Master Output: Adjust the MASTER LEVEL knob to control the overall output volume to your main sound system.
  5. Booth Output: Adjust the BOOTH LEVEL knob for your monitor speakers.
  6. Headphone Monitoring: Press the CUE button on any channel to pre-listen to its audio through your headphones. Adjust the HEADPHONE LEVEL knob for comfortable listening.

4.3 Equalization (EQ)

  • Channel EQ: Use the HIGH, MID, and LOW knobs on each channel to adjust the tonal characteristics of individual audio sources.
  • Master EQ: The 3-band master EQ allows for overall tonal adjustment of the mixed output. The kill switches provide a complete cut (-60 dB) for dramatic effects.

4.4 Crossfader Operation

The crossfader allows for smooth transitions between channels assigned to either side A or B. Use the assign switches above each channel fader to route the channel to A, B, or bypass the crossfader entirely.

  • Move the crossfader to the left to hear channels assigned to A.
  • Move the crossfader to the right to hear channels assigned to B.
  • Center position blends both A and B channels.

4.5 Microphone Usage

Connect your microphone, then press the MIC ON/OFF switch to activate the microphone channel. Adjust the MIC LEVEL knob and the HIGH, MID, LOW EQ controls for the desired sound. Be mindful of feedback when using microphones.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Stanton RM-50 DJ Mixer.

  • Cleaning: Regularly wipe the exterior of the mixer with a soft, dry, lint-free cloth. Avoid using abrasive cleaners, solvents, or waxes. Do not spray liquids directly onto the unit.
  • Ventilation: Ensure that the ventilation openings are not blocked. Dust accumulation can lead to overheating.
  • Storage: When not in use for extended periods, store the mixer in a cool, dry place, protected from dust and extreme temperatures.
