1. Input Level Control: Allows adjustment of the level of the signal going into the unit. For best signal to noise ratio, adjust this control until the Peak LED (#2) flashes on strong signal peaks. The center detent position is "unity gain."

2. Peak LED: Lights when the input signal is within 6dB of clipping.

3. Bandwidth: Allows adjustment of the width of the band of frequencies affected by the unit. In the extreme counter clockwise position, the bandwidth is .05 octaves; the center detent is 1 octave and the extreme clockwise position is 3 octaves.

4. Frequency: Allows adjustment of the center frequency of the band affected by the unit. Band #1 is adjustable between 15Hz and 600Hz; band #2 between 175Hz and 5.7kHz and band #3 between 630Hz and 22kHz.

5. Level: Allows adjustment of the amount of boost or cut applied to the affected band of frequencies. The extreme counter clockwise position is 30dB of cut; the center detent is flat (unity gain – no cut or boost) and the extreme clockwise position is 15dB of boost.

6: Active Switch and LED: The unit will only affect the signal when this switch is in – the adjacent LED will light when active. This is useful when comparing the processed signal (switch in) to the original signal (switch out).

7. Power Supply Jack: Plug the small metal barrel connector of the AC power adapter here.

8. Cord Cinch: Use this clip to secure the cable of the power pack to the chassis of the SM3-PE.

9. Output Jack: This balanced 1/4" jack* carries the output signal from the SM3-PE to its destination.

10. Input Jack: This balanced 1/4" jack* receives the input signal into the SM3-PE. *tip = signal +, ring = signal –, sleeve = ground
