THE AUDIO LEVEL CONTROLS AND MIXING

The DRIVE control adjusts the signal level at the Bass MuRF’s circuit input. With this control you can set the right input level for virtually any instrument or line-level signal source. Turn this control counterclockwise for strong input signals, and clockwise for weaker sound sources.

The DRIVE light tells how strong the input signal is after being adjusted by the DRIVE control. As the signal level increases, the light goes from off, to green, to yellow, and finally to red. Very weak signals do not light up this light at all. When the light is green, the signal is below the level that results in audible distortion. When the light is yellow, some low order distortion may be audible, giving the sound a subtle warm analog quality. When the signal is strong enough to drive the light into the red, the distortion at the output becomes stronger and more distinctly audible. Watch this light when you set the DRIVE control for the desired effect.

The OUTPUT control adjusts the strength of the Bass MuRF’s signals that appear at the LEFT/MONO and RIGHT output jacks. Use this control to balance the Bass MuRF’s signals with the bypassed signal. Note that neither the DRIVE nor the OUTPUT controls affect the strength of the bypassed signal.

USING BOTH AUDIO OUTPUTS TOGETHER

The Bass MuRF has two audio outputs: LEFT/MONO and RIGHT. When a cable is plugged into just the LEFT/MONO jack,

the output of all filters are sent

to that jack. If a cable is inserted

into the RIGHT jack, then half of the filters are sent to the

RIGHT output, and half are sent to the LEFT/MONO output. .

Figure 12 shows the frequency response of the left and right outputs when both the left and right output jacks are used.
