PRE-200 PREAMP CONTROL FUNCTIONS, JACKS, & INDICATORS:

FRONT PANEL (CONTINUED)

Treble Level Adjusts the high frequency level. Clockwise (CW) boosts the level of highs,

counterclockwise (CCW) cuts the level of highs. The level is adjustable from -16
dB cut to +16 dB boost. Start at 5 (flat) and adjust to taste.

Mid Frequency Sets the frequency at which the Mid Level control has an effect. Several

frequency intervals between 250 Hz and 1000 Hz are marked.

Mid Level Sets a boost or cut in the mid range frequencies selected by the Mid Frequency

control. Level is adjustable from -20 dB cut to +5 dB boost.

Bass Level Controls low frequency response. Start at 0 (flat) and adjust to taste.

CW is boost, CCW is cut. Level is adjustable from -16 dB cut to +16 dB boost.

Blend Only set this control after you have set the others. This is to be used as a sonic

“shading” control and, like any seasoning, a little goes a long way. Start at
12 o’clock. CW yields a “Mooney” bright aggressive sound; CCW gives you a
mellow, darker tone.
