Mitsubishi Electronics XL21, XL50 installation manual AMP. Gain for S.ANALOG input

Page 59

1.7.4.3. AMP. GAIN (for S.ANALOG input)

Used to adjust the gain level of an analog signal in the input board. Due to uneven AD converting levels of analog input, colors in each screen look different even if the CSC adjustment is appropriate. It is effective in each input memory. It cannot be adjusted when the input signal is YUV signal.

[Procedure]

1.Display a full-white signal through an actual input route.

2.Select AMP GAIN in the input memory menu (on the 4th menu sheet).

3.Select AUTO GAIN and press [ENTER] button in reply to “AUTO GAIN START?” message.

4.The optimum value is automatically set. The adjustment will finish when “CALCULATE…”

indication disappears. [When “ERROR” is displayed]

An error message is displayed if the input signal level exceeds the adjustment range i.e. the level is too low or too high, or a full-white signal is not input. In such cases, it is necessary to input a signal with the optimum level.

[Manual adjustment]

Normally the AUTO GAIN adjustment is recommended. In special case such as a full-white signal cannot be input, the manual adjustment may be helpful.

1.Select AMP GAIN in the input memory menu (on the 4th menu sheet).

2.Select MANUAL GAIN.

3.Adjust R/G/B-GAIN or R/G/B-LEVEL respectively.

[NORMAL] button can reset it to the values in SCALER AMP GAIN in the system memory (chapter 1.5.3.3, on page 49). If it has not been set, it restores the factory setting values.

1.7.4.4. H.SIZE, V.SIZE

This adjustment is normally unnecessary. The optimum value is automatically set in automatic input signal scanning.

Used to adjust an incorrect size of an effective input image area after H.TOTAL (in S.ANALOG input) and H.POSITION, V.POSITION adjustment.

[Procedure]

1.Select H.SIZE in the input memory menu (on the 1st menu sheet).

2.Adjust the horizontal size of the input signal.

3.Select V.SIZE in the input memory menu (on the 1st menu sheet).

4.Adjust the vertical size of the input signal.

Note: when you change the H.SIZE or V.SIZE, H.DISPLAY POS and V.DISPLAY POS in the display memory should be 1/1 in advance (chapter 1.7.2, on page 57).
