This section of your ULTRA-VOICE contains a preamplifier that allows you to determine the input
level of mic or line signals.
1
Use the LINE switch to select the type of input signal used (in = LINE; out = MIC).
2
Press the +48V switch to provide condenser microphones with the necessary phantom power supply
voltage. Dynamic microphones need no additional supply voltage.
3
The GAIN control adjusts the input level. The scale ranging from -12 to +12 dB refers to the LINE input,
the 10 through 60 dB scale to the MIC input.
4
The SIG LED above the GAIN control lights up as soon as a signal is present at the input.
5
Make sure that the CLIP LED lights up only occasionally during loud passages. If it lights permanently
or you can hear audible distortion, you should reduce the input level with the GAIN control.
6
The ULTRA-VOICE has a low-cut filter that eliminates low-frequency interference from your microphone
signals. Use the LO CUT switch to activate this function. The filter has a slope of 12 dB/oct.
7
With the FREQUENCY control you can determine the frequency below which interference signals are
suppressed (15 Hz through 360 Hz).
8
The Ø INV switch inverts the signal phase by 180°. Use this function in a multi-microphone set-up if you
detect phase cancellations in specific frequency bands.
