RUMBLE FRONT PANEL FUNCTIONS
A. A VOLUME - Adjusts the volume of Channel A.
B. TREBLE - Adjusts the level of high frequencies in Channel A.
C. BASS - Adjusts the level of low frequencies in Channel A.
D. MIDDLE - Adjusts the level of mid frequencies in Channel A.
E. MID - Selects whether pre-set mid frequencies are to be attenuated in Channel A.
F. SELECT - Selects Channel A or Channel B to be sent to the speaker jack. SELECT only
operates when CHANNEL (see item J) is in “switch” mode.
G. A INPUT - A high impedance, high sensitivity plug-in connection for Channel A.
H. A/B INPUT - A high impedance, high sensitivity plug-in connection for Channel A and/or
Channel B. If CHANNEL is in “switch” then Channel A or Channel B (depending on SELECT set
ing) is sent to the speaker jacks. If CHANNEL is in “combine” then Channel A and Channel B are
mixed and sent to the speaker jacks. The two channels are mixed after all tone shaping sections
of the pre-amplifier.
I. B INPUT - A high impedance, high sensitivity plug-in connection for Channel B.
