System Connection & 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 subgroup insert jack(s) of a mixer.
3. Connected to the insert jack(s) on the master outputs 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 to the AFS 224 should
consistently light the 0dBu LED, with the +10dBu LED occasionally lighting. Hookup methods 1, 2,
and 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 channel 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 level of the insert jacks, and then select the +4dBu or -10dBV switch on the back of
the AFS 224 accordingly.
If no insert points are available, then method 4 would be utilized. In this situation, be sure that the AFS
224 input level allows the 0 and +10dBu LEDs to light as indicated above. The input level to the amplifiers
may have to be reduced in this situation so that they are not overdriven by the signal from the AFS 224.
