The matrix on the left displays the input channel – to – output channel mapping.
To make assignments, first dial in the output channel, then edit the input channel and other options.
1. Dial in the output channel number. Touch the field and use the adjustment knob to change
the setting.
2. Then edit the input channel. Input channel may be assigned 1-16. Output channels may
share the same input.
3. Set Low pass filter. Options are Off, 6, 12, 18, and 24 dB/octave and from 20Hz to
20KHz. Low pass filters can be used even if crossover is not selected.
4. Set High pass filter. Options are Off, 6, 12, 18, and 24 dB/octave and from 20Hz to
20KHz. High pass filters can be used even if crossover is not selected.
5. Set Output Channel Trim. The Output channel trim may be set from 0dB to -10dB in
0.5dB increments. The output trim may be used to balance the levels of crossover
channels.
Note : The output channels are assigned one of the following letter IDs ( Crossover ID ): W, L,
M, H, and 0-9. This is used for reference for the output channel and has no functional purpose
at this time.
4.3.8.4.4. Example Crossover Setup
When setting up the RS20i crossovers, you will need to identify the speaker model used and obtain its
technical specifications. Speaker technical specifications can usually be found on the manufacturer’s
web site.
In this example, we are setting up the RS20i Left channel ,
input 1
, for 3-way crossover using the
model JBL 2632-T speaker. There are three main steps to this process, as shown below. The
specification sheet for the JBL 2632-T lists its frequency range as 30Hz to 20kHz and crossover
frequencies as 350Hz and 1.2kHz.
