Keyboard Amplifier
The Front Panel:
4
1: INPUT 1: Use this 1/4” jack to connect your keyboard, tape player or
Hi-Z microphone to the amplifier by means of a shielded instrument
cable. Use the Volume 1 control (#3) to adjust the signal at this jack.
2: INPUT 2: Use this 1/4” jack to connect your keyboard, tape player or
Hi-Z microphone to the amplifier by means of a shielded instrument
cable. Use the Volume 2 control (#4) to adjust the signal at this jack.
3: VOLUME 1: Use this control to adjust the level of the signal at the
Input 1 jack (#1).
4: VOLUME 2: Use this control to adjust the level of the signal at the
Input 2 jack (#2).
5: LOW: Use this control to adjust the bass response of the amplifier.
Rotating the control counterclockwise reduces the low frequency output.
Rotating the control clockwise increases the low frequency output. The
Low control provides a range of 15dB of boost or cut at 60Hz. It may be
necessary to reduce the Low frequency output at higher volume levels.
6: LO MID: Use this control to adjust the “thickness” or “fatness” of the
amplifier. Rotating the control counterclockwise reduces the lower mid-
dle frequency output. Rotating the control clockwise increases the lower
middle frequency output. The Low Mid control provides a range of 18dB
of boost or cut at 630Hz.
7: HI MID: Use this control to adjust the clarity and definition of the ampli-
fier. Rotating the control counterclockwise reduces the upper middle fre-
quency output. Rotating the control clockwise increases the upper mid-
dle frequency output. The High Mid control provides a range of 19dB of
boost or cut at 2kHz.
