Exercise caution when playing at high volume levels with large amounts of low

frequency boost. When playing outdoors, it may prove beneficial to slightly cut low

frequencies to provide more headroom and louder playing volume.

6. LOW FREQUENCY CONTOUR: This switch provides 15 db boost at 40 hz. It is

especially useful when playing at lower volumes to create a "warm" sound.

7. HIGH FREQUENCY CONTOUR: This switch provides 15 db of boost a 4 khz. It is

very useful for giving you extra presence or edge.

8. BI-AMP/MONO SWITCH: Use this switch to select Bi-Amp or Dual Mono operation. In

the Bi-Amp mode, the built-in crossover is activated - low frequencies are sent through

the low channel and high frequencies are sent through the high channel. In the Mono

mode, the same signal is sent through both channels.

9. BRIDGE SWITCH: Use this switch to change amp operation into and out of the bridge

mode. Bridge mode combines the two output sections into a single one. You'll get twice

the power into twice the load (8 ohms). Using the bridge mode forces the amp into a

mono operation, i.e. you cannot run your amp in bridge mode and bi-amp mode at the

same time.

10. BRIDGE MODE INDICATOR L.E.D.: This shows you that the bridge switch is

activated and that the amp is running in Bridge mode.
