receives this command through the ground created by the phone plug making contact with the jack. The plug must be a mono plug (tip and ground). If you have a stereo plug only, it will be necessary to tie the ring and the ground together. SubWave� Activator Footswitch Your Black Beauty comes equipped with the capability for hands-free control of the SubWave� effect. To achieve this function, locate the footswitch included in your Black Beauty packaging. Connect the cable to the SubWave� Footswitch jack on the rear of your Black Beauty. Turn the effect on and off by stepping on the switch; the illuminated switch above the SubWave� Level control on the front panel should alternate on (blue) and off, and the effect should engage and disengage accordingly. Note: The type of switch contained inside the footswitch chassis is momentary, normally open. If you connect the footswitch to the unit while the unit is on, the SubWave effect may engage. This is normal. Tweeter Mode Switch This three-position switch gives you the choice of three different options for operation of the horn tweeter. In the Full Range (top) position, the tweeter will reproduce an unattenuated signal of every frequency it sees (roughly 2 kHz up to 15 kHz, within certain tolerances). The �6db (bottom) position reduces the level of the tweeter�s outputs by 6 decibels, which to the ear sounds roughly as if cut in half compared to the Full Range position. The Off (middle) position will defeat the tweeter�s output entirely. Try starting with the switch in the Full Range position. If this sounds too �treble-y� to your ear and you still want the touch of crispness that a tweeter provides, you can: a) Set the Tweeter Mode Switch to �6db; b) Adjust the Treble tone control on the front panel; c) Try a combination of both. Those users with a predisposition against a tweeter in general have the option to turn it off and leave it off, but we recommend trying it out first. Speaker Mode Switch This two-position switch controls the signal sent from the power amplifier to your speaker cabinet (and extension speaker if connected). When set to the On (top) position (default setting from the factory), the Black Beauty will operate normally and the sound of your amplified bass will be heard from the speaker cabinet. When set to the Off (bottom) position, that signal will be defeated regardless of the settings on the front panel. This can be useful for silent practicing (in conjunction with the Headphones Jack, listed below), or for defeating the audio while you re-patch cables or plug and unplug your instrument. This switch will not affect the signal present at the various audio outputs (XLR, Effects Send, Tuner Out) or the Headphones Jack. Note: If the volume on your instrument is up, and your Gain and Master Volume controls are up, and especially if you�re seeing the Preamp Clip and Limiter Active LED�s illuminate while you�re playing�and you can�t understand why you�re not getting any audible output from the Black Beauty, check the position of this switch! Headphones Jack (Stereo Only) By inserting a set of stereo headphones into this jack you can monitor your sound more closely in a studio situation, or practice silently (when the Speaker On/Off Switch is set to �Off�) so as not to completely annoy your neighbors. The headphone volume level is adjusted by the Master Volume. We suggest you begin with the Master Volume full off (counter-clockwise), then slowly bring up the volume to the desired level. If you hear some distortion in your headphones that isn�t present through your speaker system, turn down the Master Volume. You are probably overdriving your headphones and could ruin them, to say nothing of what you may be doing to your ears. Any impedance headphones will work. However, optimum impedance is 75 ohms. Combo Cabinet Jack/Plug Assembly The black cable/plug assembly that comes out of the cabinet and is connected to the rear panel (near the text marked �Combo Cabinet�) is the means by which the power amp in your Black Beauty sends its signal to the speaker complement. Both the plug and the jack it connects to are a special size, slightly
