Shure SE22 Schematic
paralleled) as a monophonic source to one channel of the SE22, the SE22 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.

Channel Level Controls
These controls are located on the front panel designated as "A Level" and "B Level." They are used to adjust the overall operating level of the SE22 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 monophonic cartridges, highand 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.
