[. . . ] Press the SETUP Push-button to exit the Setup Mode. Tuning Method TUNE - 4. Rotate the INPUT Control clockwise until the display indicates "INPUT 1 PH". Press the SETUP Push-button to exit the Setup Mode. Level Adjustment Various Source Components can have slightly different volume levels. This could result in the constant need to readjust the C45 Volume Control when switching between different Input Sources. The Level Input Trim Feature on the C45 allows the adjustment of levels for each of the Source Inputs, so that they have the same relative volume. Refer to figure 3 on page 15. Notes: The possible range of adjustment in volume level is ± 6dB. The Tape/Record Output Levels are unaffected by any changes in the Level Trim Settings. Any LEVEL Trim adjustments made are retained in permanent memory and can be changed only by performing a new Level Trim Procedure. The Tuner Input Volume Level can serve as a reference or choose another Input Source that is frequently listened to as the reference. The reference Input Source should be set to a Level of 00. Re-Title Inputs The C45 has nine Audio Inputs, which include the optional TM1 AM/FM Tuner Module. These inputs already have assigned titles that will allow for immediate hookup, operation and enjoyment. In addition, there are two 6 channel inputs and a balanced input that are assignable as replacement for each one of the inputs. If these starting assignments do not match up with components in your system, they may be reassigned from the default settings. The following example will illustrate how to rename the AUX Input to PHONO. When the Input Selector is rotated to select what was originally the AUX Input, PHONO will now appear on the Front Panel Alphanumeric Display. Unused Inputs may be switched Off so they will not appear when rotating through the input source choices using the Input Selector and also will not be available when using the Remote Control or Keypad. The New Input Titles that are available for all the Inputs include TAPE 2, LV, TV, and VCR2. The AUX Input (INPUT 1) Titles also includes PHONO. Figure 12 1.
