Working with vocals using external effects devices

Often, vocalists use external effects such as Echo, Reverb and Key Control. While enhancing vocals, these effects can also limit the signal’s sound quality. The DA-8909RV’s Vocal Enhancer can help “clean up” the vocal signal after effects have been applied.

The frequency bandwidth of most vocals is approximately 300Hz - 6kHz. The DA-8909RV can improve the sound quality of frequencies across this range so that microphone input has a more natural and clean sound. Nuances of your vocals can be emphasized without affecting the overall sound. Since every voice is different, we recommend that you experiment with different settings to find the sound which best suits your preferences.

Using the Vocal Enhancer

Use of the Vocal Enhancer will increase your speaker system’s acoustic performance and its audible level in a room. This is particularly effective in environments with difficult acoustics. When using the DA- 8909RV’s Vocal Enhancer, MIC MASTER VOLUME level may need to be adjusted as perceived

volume increases.

1.Connect a microphone with a 1/4” cable to MIC INPUT 1, 2 or 3.

2.Select the VOCAL ENHANCER to the ON (in) position.

3.Start with the HIGH, PROCESS, TUNE and LOW controls at their center positions.

4.Adjust the HIGH and LOW clockwise or counterclockwise until you find a comfortable balance where they are both equally audible while neither is causing feedback or distortion of the signal.

5.Now adjust the TUNE controls until you reach the desired cutoff frequency for the high-pass filter. Ultimately, you should be able to settle on a “sweet spot” frequency setting that improves the overall tone of your treble and bass without leaving either sounding harsh or dominant in the mix.

6.For further fine tuning, think of the PROCESS control as an overall balance between HIGH, or treble (TOP) and LOW, or bass (BOTTOM). This is a largely a matter of preference, so you should experiment to find the PROCESS setting that best suits your ears.

7.Try an ON/OFF comparison with the VOCAL ENHANCER to get a better idea for how it is improving your tone and to better acquaint yourself with the result of adjusting the controls .
