Mesa/Boogie Walk About Bass Amplifier owner manual DI Level Master

FRONT PANEL CONTROLS: (Continued)

DI LEVEL: This rotary control determines the amount of signal present at the Rear Panel DIRECT OUT XLR jack. You will find ample gain here and should be able to dial in the appropriate amount of signal for most any live or recording console. It is a good idea to get in the habit of powering up your WalkAbout with the DI LEVEL control Zeroed out, to avoid damaging the console, speakers or an unpre- pared set of ears in the event you strike a big note or chord before the console input level has been set.

MASTER: This basic control determines the overall final output level of your WalkAbout so that you can adjust the front end GAIN control to your tonal needs and then push the SIMUL-STATEpower section to the desired listening level.

NOTE: Use the MASTER output level control with care. The WalkAbout is capable of very loud output volumes that could potentially cause damage to your hearing or the hearing of others. May we suggest always beginning your set-up by zeroing-out the MASTERoutput level control to avoid accidental volume attacks on unsuspecting bandmates, engineers or audiences.

PARAMETRIC EQUALIZER: Your WalkAbout is equipped with a powerful in-line 3 BAND SEMI-PARAMETRIC EQUAL- IZER that allows you to shape your signal to achieve virtually any sound. Anything from subtle enhancement to extreme notching or boosting is possible with the only limit being your imagination. As mentioned earlier, the EQ is an in-line type, which means that it is in the signal path at all times. If you do not wish to shape your signal with the EQ section of the preamp, simply leave all the controls set to 12:00 (straight up) and the EQ will pass the signal unaffected. This

12:00 setting would be considered “flat” or in other words, basically bypassed.

GAIN: These 3 GAIN controls adjust the amount of whatever frequency has been zeroed-in on for manipulation with the FREQUENCY control. Each of the 3 GAIN controls allows a full 30db of gain adjustment with 15db of cut and 15db of boost from the center 12:00 (0db) position. When searching for sounds it is sometimes faster to either notch or boost the respective GAIN control radically and then sweep for the desired frequency with the FREQUENCY control. This way it will be very apparent what you are doing to the sound.

This is a good place to mention that, because of the strength of the 3 GAIN controls, it is possible to very quickly go beyond the realm of balanced musical tone and blow holes in your mix. Therefor, start by building a great sound using the standard rotary TONE controls and then begin with subtle tweaking of the frequencies using the PARAMETRIC EQ. Don't start boosting everything all over
