AFS Filter LEDs: The AFS 224 offers 24 filter LEDs per channel, which are used to indicate the
number of fixed and set filters within each channel.
This section of the manual is provided to give the user step-by-step instructions for setting up
and optimizing the performance of the AFS 224.
A - Setting Gain Structure
The four basic ways to hookup the AFS 224 to your system are as follows:
1) Connected to the insert jack(s) on a microphone channel of a mixer.
2) Connected to the insert jack(s) on the main outputs of a mixer.
3) Connected to the subgroup insert jack(s) of a mixer.
4) Connected inline w/outputs of a mixer (output of mixer to input of 224, output of 224 to amplifiers).
For maximum performance and proper operation, the average input signal should consistently
light the 0 dBu LED, with the +10 dBu LED occasionally lighting. Hookup methods 1, 2 & 3
above are the preferred way to connect the AFS 224 since the insert points on most mixers are
pre output fader. This allows the proper signal level to be fed to the AFS 224 without the chan-
nel or output fader affecting the level as the fader is moved up or down. Be sure to check the
mixer's manual for the nominal operating point for the insert jacks, and then select the +4dBu
or -10dBV switch on the back of the AFS 224 accordingly.
