The Front Panel - Crate CA15 User Manual

The Front Panel:

1
1,3: Input 1, Input 2. The signal output from your acoustic instrument, tape
player, rhythm machine, high-Z microphone or other source may be con-
nected to either or both of these jacks by means of a shielded signal cable.
Each of the input jacks is governed by its corresponding gain control (#2
for Input 1, #4 for Input 2). The signals from these two jacks are summed
together after their input gain stages.
2,4: Gain 1, Gain 2. Use these controls to set the input gain level for the cor-
responding input jack. These controls set the level of the input signal and
serve as the amplifier's volume controls.
5: Low. This serves as the bass control for both channels. Adjust this control
to get the best sounding bass response for your instrument. Excessive
boost of the low control can cause an unnatural howling (acoustic feed-
back from your instrument) and should be avoided.
6: Mid. This serves as the midrange control for both channels. Adjust this
control to get the best projection and midrange tones for your instru-
ment.
7: High. This serves as the treble control for both channels. Adjust this con-
trol so your high notes and harmonic overtones are lively but not over-
powering.
8: Reverb Level: Use this control to adjust the amount of reverberation
added to the signal. In the fully counter clockwise position, the signal is
dry (no reverb added). As you rotate the control clockwise the amount of
reverb increases.
