    1 volt RMS. Basses with really “hot” pickups may be more compatible with this input. If you are using a KEYBOARD or BASS PEDAL, etc. with the SM-500, we have found the best choice to be the Active input.

    Equalizer to +15 (the Frequency control should be set at 40Hz, which is the fundamental that the open “E” string produces). The change in sound and pressure levels is a result of the fundamental “E” note being increased by approximately 15db. SM-500 USER GUIDE • 5...

  • Page 7: Speaker On/Off Switch

    Stereo Master Volume control is a dual-concentric knob that offers individual volume control over both the right side (outer knob) and left side (inner knob) when the SM-500 is being run in the Stereo Mode. When the SM-500 is being run in the Bridge/Mono Mode, the inner knob controls the overall volume (the outer knob is disabled and will have no effect in Bridge/Mono Mode).

    SM-500 REAR PANEL FEATURES AC CORD RECEPTACLE The SM-500 accepts a standard AC power cable (supplied with the SM-500), used with almost all cur- rent musical, professional and household electronic devices. If it becomes misplaced, a replacement can be purchased at almost any computer, electronics, or pro audio store.
  • Page 9 There are two 1/4" jacks and one Speakon SM-500. The Left and Right speaker jacks are provided for use in the Stereo Mode only. DO NOT use these jacks when the SM-500’s Power Amp Assign switch is in the “Bridge” position. You can bal- ance the Left and Right channels by using the Stereo Master Volume control located on the front panel.

  • Page 10: Effects Section

    If you wish to use just the internal power amps in the SM-500, the Effects Return jacks will serve as the “inputs.” Insert your MONO signal source in the mono Effects Return jack. This will send the source to both power amps.

  • Page 12: Rack Mounting Instructions

    The SM-500 takes up two full rack spaces (3 1/2"). If the rack in which you mount the SM-500 requires that the rubber feet on the bottom of the chassis be removed, please remember to REPLACE the screws, as they help to reinforce the chassis.
  • Page 13 You should be aware of the possibility of the power amp in your SM-500 becoming “over biased.” This condition can be recognized by turning your amplifier on and letting it sit without speakers plugged in and without playing it.
