THE AUDIO LEVEL CONTROLS AND MIXING

The DRIVE control adjusts the signal level at the MIDI 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 nally 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. Using the distortion generated by the DRIVE

control in some cases can help make the MIDI MuRF’s lters sound

stronger as distortion adds harmonics to the input signal.

The MIX control is used to balance the dry and effected signals when

the MIDI MuRF is active. At full counter clockwise, the output signal is

the dry signal, as modied by the DRIVE control. At mid-position, the

balance of dry and wet signals is 50%/50%. At full clockwise position,

the output signal comes from only the MIDI MuRF’s lters.

The OUTPUT control adjusts the strength of the MuRF’s signals that

appear at the LEFT/MONO and RIGHT output jacks. Use this control to

balance the 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 MIDI MuRF has two audio outputs: LEFT/MONO and RIGHT.

When a cable is plugged into just the LEFT/MONO jack, the outputs of

all lters are sent to that jack. If a cable is inserted into the RIGHT jack,

then half of the lters are sent to the RIGHT output, and half are sent to

the LEFT/MONO output. Figure 12 shows the MIDS frequency response
