FRONT PANEL CONTROLS: (Continued)
BASS: (Continued) This type of broad band, active rotary control makes it possible to achieve bass characteristics far beyond that of a conventional passive type control. It can increase the low end to an almost absurd level and with a flick of the wrist, dip it to near transitor radio skinniness. Needless to say, with any control this powerful a certain amount of finesse must be applied to achieve musical results. Be especially mindful of this when using the 5 Band Parametric in conjunction with the BASS control.
PASSIVE MID: This is the only passive style control in the string of rotary tone controls. This scheme was chosen for its inherently musical blend and for the way the passive style midrange control, with its wide spread and smooth taper, fills in the holes.
Unlike the BASS, this control is a boost only, and while it can competently remove this broad spectrum of midrange from the mix, it cannot provide the extreme attenuation of an active style

For radical and specific scooping of the midrange frequencies for modern R&B and Funk styles, there is plenty of notching power that is infinitely more accurate to be found in the ACTIVE MID. Because of this, we opted for the tried and true passive style midrange control that has been working great in all of our amplifiers for decades. It’s hard to improve on a classic.
ACTIVE MID: In addition to the passive style MID control, the BIG BLOCK features an ACTIVE MID circuit that allows further accentuation of specific midrange frequencies across a wide band. This wider band covers the spectrum from high bass/low mid all
the way through to high mid/low treble frequencies.

GAIN | BASS |
As you can see, this active circuit is made up of two controls; a GAIN control which is labeled ACTIVE MID that boosts and cuts the selected region, and a FREQUENCY control that allows selection of a specific range to manipulate. The ACTIVE MID is the gain or “amount” control. It provides 15db of gain in both plus (boost) and minus (cut) directions at the specific range selected on the FREQUENCY control.
Remember that this is a powerful control and that certain frequencies cut through (high mid/low treble) or seem especially loud (low mid/bass) so it is advisable to add gain with the ACTIVE MID control sparingly.
Set unwisely, this circuit is capable of creating sounds that are harsh, tubby or just simply unbalanced. This combined with the massive power available in the output section can spell real danger to speakers. We urge you to use this ACTIVE MID circuit with care and most of all taste, to avoid damage to your ears and speakers.
These two simple controls offer an incredible amount of shaping power in a simple to use format. When combined with the other tone controls, virtually any sound you desire is available to you quickly and with far less searching than when using
