monaural source to one channel of the SE20, the SE20 input should be shunted with a 47,000 ohm resistor or the high frequency trimmer should be readjusted for proper high frequency equalization. Outputs: Output terminals appear on the rear panel as shown in Figure C. Outputs are balanced and designed to feed a 150 ohm or 600 ohm line. REAR PANEL FIGURE C Channel Level Controls: These controls are located on the front panel designated as Channel A Level and Channel B Level. They are used to adjust the overall operating level of the SE20 and to balance the individual levels of the two channels. Response Trimmers: To allow for balancing the response of the two channels of a stereo cartridge, or of two monaural cartridges, high and low frequency response trimmers are provided for each channel. Figure D shows the location of these controls and Figure E shows the range and character of the response change obtainable.
