Adjust the gain by dialing the rotary encoder. The gain is adjusted in steps of 0.25dB.

The DS20 inputs are fixed. Input 1 is routed from the analog XLR-input of channel 1,

Smaller steps (0.01dB) can be set via the PC or MAC interface.

channel 2 is routed from the analog XLR-input of channel 2, channel 3 and 4 are routed
from the digital AES/EBU XLR-input on the backside of the DS20.

Adjust the Low Pass Filter frequency by turning the rotary encoder. You can switch the low
pass filter off by turning the rotary encoder up (clockwise) until the frequency passes 20kHz.
Press the rotary encoder to change the filter type. Selct the type by turning the rotary encoder.
You can choose from: Butterworth 6dB, Bessel 6dB, Butterworth 12dB, Bessel 12dB, Linkwitz
Riley 12dB, Butterworth 18dB, Bessel 18dB, Butterworth 24dB, Bessel 24dB. Higher order
filters may be set by adding filter sections in the PEQ blocks (see below).
Enable or disable the Low Pass filter by rotating the encoder between on and off.

controlling the DS20 with Stage Control the displayed unit can be changed between ms or s,
mm or m, feet, inches, or mils.
