3. setup and operation
Before plugging the processor in, always make sure that the power supply matches the product specification voltage. Install this
device on a flat, stable surface. Do not supply power before all components of the system are set up and connected properly. Make
sure to power-up your device before your power amplifiers are switched on in order to avoid transients, which could damage you.
3.1. system check
After connecting all cables, you should mute all outputs first or turn the gain/level setting on your amplifiers to minimum. Activate
the HF-outputs first. In case of wrong cabling, High Frequency (HF) audio signals will come out of bass-speakers that cannot be
harmed this way. Vice versa, the Low Frequency (LF) audio signals would destroy your HF-speakers.
3.2. input setup
Press the Channel Up or Down button to select the input channel you wish to edit. Make the first settings with the output turned low
or muted. To toggle through the different menus, press the Item Up or Item Down buttons.
3.2.1. gain
Adjust the gain by dialing the rotary encoder. The gain is adjusted in steps of 0.25dB. Smaller steps (0.01dB) can be set via the
PC or MAC IDEA DSPControl software.
3.2.2. input selection
Select the source (Analog or AES/EBU) by rotating the encoder.
3.2.3. delay
Set the delay time by turning the encoder. Select the displayed unit (ms or s, mm or m, feet, inches, or mils) by pushing the
encoder.
3.2.4. low pass filter
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. Select the type by turning the rotary encoder. You can choose from: But-
terworth 6dB, Bessel 6dB, Butterworth 12dB, Bessel 12dB, Linkwitz Riley12dB, Butterworth 18dB, Bessel 18dB, Butterworth
24dB and Bessel 24dB. Higher Order filters may be set by adding filter sections in the PEQ blocks (see below).
