26、he middle frequen- cies, the the 4K, 8K, and 16K sliders vary the high or treble frequencies. The AGC compressor keeps transient signals like pops or feedback under control, so they wont damage your hearing. It also slightly brings up low-level signals. NOTE: Much of the signal content may not be co

To use external effects processors, connect the FX Send jack to the Input of your effects unit, connect the output(s) of the processor to the Effects Return jacks (See the connection example on Page 3).
28、If you are using a mono signal out of the processor, use the Right/Mono jack. The Effects Send controls 1 - 4 and Main adjust the amount of signal from the indicated input out the Effects Send jack and to your effects processor.
