Figure 11 Stereo Blend The AA2 allows changes in the amount of Stereo Separation via the Stereo Blend Function. When receiving weak FM Stereo Broadcasts any background noises can be reduced by blending some of the left and right channel information together, while still maintaining "The Stereo Effect". To change from the Normal Setting perform the following steps: 1. Press the MONO/SETUP Push-button until the Setup Mode is active. Then rotate the PRESET/ MENU Control to select Setup Menu item "SETUP: STEREO BLEND NORMAL". Refer to figure 9. Deemphasis The FM Transmission Standard uses Preemphasis (boosting the volume level of the high frequencies) of the audio signal before transmssion. Inside the tuner Deemphasis (cutting the volume level of the high frequencies) is used to return the audio signal to the correct high frequency volume levels. The use of Preemphasis and Deemphasis helps to reduce losses and noises during the transmission/receive process. Any preset station may be removed from memory at any time. There are times when it may be desirable to remove from memory all or some of the preset stations. To accomplish this perform the following steps: 1. Press the MONO/SETUP Push-button until the Setup Mode is active. Then rotate the PRESET/ MENU Control to select Setup Menu item "SETUP: PRESETS".
