Quick Start Guide

This step by step tutorial is based on a basic configuration

(AFS224 in line between mixer and amplifier) as shown below.

1. Go into the Setup mode by pressing and holding the channel 1 MODE button.

2. Hold this MODE button until the filter LEDs flash all the way across.

3. The Mode buttons should be lit a yellow or amber color. If they are not press each

MODE button until they are both yellow. The filter LEDs will indicate how many

total filters will be active.

4. Select how many total filters that you want active. The default of 24 is a good

place to start. However, if you want to change the total # of filters, press the

LIVE FILTER LIFT button to increase the # of total filters for each channel or

the TYPE button to decrease the total # of filters for each channel.

5. Press the Mode buttons. They should now be lit green. The filter LEDS will

indicate how many of these total filters will be allocated as “Fixed” filters.

Press the LIVE FILTER LIFT buttons to increase the # of “Fixed” filters for each

channel. Press the TYPE buttons to decrease the # of “Fixed” filters for each channel.

The default of 12 Fixed and 12 Live is a good place to start.

Note: The difference between total filters (step 4) and fixed filters (this step) will

indicate how many “Live” filters are available.

6. To exit the setup mode, press and hold the channel 1 MODE button. Hold this

button until the filter LEDs flash all the way across.

7. Press the BYPASS buttons so that they are both lit red (bypassed).

8. Press and hold the channel 1 TYPE button to select between dual mono or stereo

mode.

Note: You can tell which mode you are in by pressing any of the buttons. If the other

channel changes as well, the two channels are working in conjunction (stereo mode).

If not, the unit is in dual mono mode.
