8.2 | Microphone/line controls |
| Use the volume controls (9) to individually control the sound level of microphone/line inputs 1 |
| through 4. |
8.3 | Music controls |
8.3.1 | Volume control |
| Use the music source volume control (8) to control the sound level of the selected music |
| source. |
8.3.2 | Tone control |
| The tone controls are not standard bass and treble controls: they can be used as a traditional |
| tone control with high and low control. |
| The tone control for the low frequencies boosts deep bass first without making the sound |
| boomy, and cuts rumble without loosing warmth in the low frequencies. |
| Use the Hi (high) and Lo (low) tone controls (see Figure 8.1, numbers 3 and 7) to change the |
| tone. |
8.4 | Output controls |
8.4.1 | Master volume control |
| Use the master volume control dial (4) to collectively control the sound level of all outputs, |
| except the emergency announcement/signal. |
