4 - Recording Adjusting the input level Before starting recording, the input level should be adjusted to prevent the recorded sounds or input signals from being distorted due to excessively loud input or from being quieter than the noise level due to excessively low input levels. In addition to manual adjustment, the unit has a limiter function that you can use as desired. (See "Using the limiter" on page 22.) TIP In addition to adjusting the INPUT level, try changing the distance and angle between the microphone and the sound source. The angle and distance of the microphone can also change the character of the recorded sound. 1. Press the MENU button to open the MENU screen. 2. Turn the DATA dial to select BASIC, and press the DATA dial. The BASIC screen opens. 3. Press the 1/8, 2/7, 3// or 4/. button to select the channel for input level adjustment. 4. Turn the DATA dial to select GAIN for the selected channel, and press the DATA dial. CH1 BASIC screen NOTE To change the channel being set, turn the data dial or press the 1/8, 2/7, 3// or 4/. button to move to a different channel screen. 5. Turn the DATA dial to set the mic input gain. Options: LOW (default), MID, HIGH, HI+PLUS NOTE The input gain is different for the LOW, MID, HIGH and HI+PLUS settings. Make a selection according to the loudness of the input. If you are not sure which setting to use, try LOW first. If the input level is too low even after adjustment, return to the INPUT screen and set it to MID. If the level is still too low, set the GAIN to HIGH or HI+PLUS and then adjust the level. 6. When finished adjusting, press the MENU button to return to the Home Screen. 7. Use the 1/L, 2/R, 3/L and 4/R knobs on the back of the unit to adjust the input levels. If an input level is too high, the PEAK indicator to the left of the knob will light red. The level meters have a b mark as a guide at −16dB. Set input level so that level changes occur near this mark without causing PEAK indicators to light red. CAUTION These also light if distortion occurs in the analog circuitry during mic input. They will not light, however, if distortion occurs in the analog circuitry during line input. NOTE To monitor the sound while adjusting the input levels or recording, connect headphones to the PHONES jack. Use the PHONES jack volume control to adjust the monitoring level. 8. Repeat steps 3 to 6 as necessary to set the mic input gain for each channel. TASCAM DR-70D 19
