    "hum" can be injected onto the cable by AC lines, stray field from electric motors or other sources. Balancing the input signal has the result of cancelling this extraneous hum. The net effect results in the lowest possible noise from long cable runs. The result is low impedance (allowing for long

    MX641 MASTER CONTROL SECTION 1. MAIN LEVEL CONTROL- The main level control adjusts the overall volume level of the mix. The "channel" volume levels will set the relative levels of each channel with respect to each other. The Main Level Control will then adjust the "overall" level of the entire mix,

    C. RVB/RTN - or Reverb Return Level adjusts the level of the internal reverb system for your mix. The EFF/RVB send controls simultaneously adjust the level of the internal reverb system (per channel) along with the effects send level. So, it is best to use ambience-type effects to best compliment
