The Front Panel: NOTE: Channel 1 and Channel 2 are independent of each other up to the Effects and Master sections. The text below (#1–10) applies to both channels. 1: Low-Z. The signal from a low impedance microphone may be con- nected here by means of a shielded, balanced microphone cable ter- minated with an XLR connector. -

Page 6: To Eliminate Instrument Feedback
To Eliminate Instrument Feedback: One of the most common problems encountered when amplifying acoustic instruments, especially in small environments, is feedback. Acoustic instruments typically have inherent qualities which cause reso- nant feedback at specific frequencies. Instrument tone controls and sound board equalizers are helpful in getting rid of the problem, but they typi- cally operate around relatively wide frequency bands. -
