Page 5: Typical Setup Procedure
Operating Instructions Typical Set-Up Procedure Turn the VOLUME control to the off position prior to connecting an input signal to either of the two input channels in order to prevent damage to the internal speaker or any nearby eardrums. Using the Channel Switch, select the desired input signal channel to be amplified. Determine the gain setting. -
Page 6: Theory Of Operation
Theory of Operation One of two inputs may be selected using the CHANNEL switch. The selected input is then amplified according to the setting of the GAIN switch. After amplification, the signal can be filtered at the frequency of the power line by use of the NOTCH filter. Particular narrow ranges of frequencies of the processed signal can then be boosted or attenuated using the GRAPHIC EQUALIZER. -
