Using the microphone
The DG 90 can use two separate microphones if an optional adapter is utilised to divide the stereo input into two microphone inputs. Input Mic
1 is the only one that can exploit the built-in Vocalizer plus it is provided with a separate audio output to allow the lead voice signal be processed
with an external mixer. To use both microphones correctly, you have to adjust the input gain using the dedicated cursor on the front panel to
reach an ideal noise signal level. To check if this level is correct, simply sing or speak into the microphone while adjusting the cursor and lis-
ten to the result. If the gain is too high, the audio signal would be unpleasantly distorted and if the gain is too low, the signal will be disturbed
in proportion with the quality of the cable and the microphone. For these reasons, it is better to spend a little bit more for a quality dynamic
and sturdy microphone and strong connection cable. Note: Some other aspects must be remembered when using a microphone:
●
Always connect the microphone with the volume of the DG 90 at zero, with the gain at zero and the amplifier turned off.
●
Keep the microphone away from the speakers as there could be Larsen/feedback effects, which could seriously damage your PA.
●
In small rooms it is preferable to use a microphone with hypercardoid diagram to avoid Larsen/feedback effects.
●
Keep the microphone on a very solid rod to avoid mechanical noises interfering with your voice.
●
Keep the microphone cable away from power supply cables and lines.
●
When you connect all your equipment remember that the speakers and the amplifier are always the last to be turned on and the first to be
turned off.
MICRO EDIT
The microphone parameters are stored in the Micro Edit menu that is called up from the main page of the display by selecting the F2 Effect
menu and then F4 Micro. The parameters relative to the microphone are correlated to the relative function push buttons and can be saved in
a Registration.
F1 Level 1: This specifies the volume of the microphone on input Mic 1. Once the parameter has been selected using the function
push button, the value is then varied using the VALUE +/- push buttons, which if pressed together at the same time reset
the value.
F2 Level 2: This specifies the volume of the microphone on input Mic 2. Once the parameter has been selected using the function
push button the value is then varied using the VALUE +/- push buttons, which if pressed together at the same time reset
the value.
F3 Pan 1: This selects the position on the stereo front of the microphone on input Mic 1. The signal of the microphone is set in the
middle when the parameter shows two dashes (- -). The value is modified using the VALUE +/- push buttons (which if
pressed together at the same time set the signal back in the middle).
F4 Pan 2: The same as F3 Pan 1 but for the microphone signal on input Mic 2.
F5 Music Vol: This balances the microphone signals with the sound generator of the DG 90. The value is modified using the VALUE +/-
push buttons which, if pressed together at the same time, set the value back at maximum. If the level of the two
microphones is not sufficient to stand out compared to the DG 90, it is useful to remember to reduce this value.
F6 Echo 1-2: A delay can be set on the two microphone signals, the intensity of which is controlled by this value. To switch between
input Mic 1 and Mic 2 press the function push button F6 cyclically. The value is entered using the VALUE +/- push but-
tons which, if pressed together at the same time, reset the value.
F7 Reverb 1-2: The same as F6 Echo 1-2, but for the reverb for each input.
F8 Pitch Shift: This only affects the signal of the microphone on input Mic 1 and is used to transpose the notes sung in the microphone
in steps of semitones. When the values are excessive the sound of the voice is distorted. This effect is one of the
Vocalizer features. The value is increased or decreased using the VALUE +/- push buttons which, if pressed together at
the same time, reset the value.
