Setting Gain/Attenuation; Adjusting Input Attenuation - AMX DAS-M-0404 Operation/Reference Manual

Notes:

Setting Gain/Attenuation

Audio Sources tend to have varying output levels. The Mi Series Controller gives the installer the ability
to raise and lower the output gain of the audio source. The installer may attenuate the source input from
0db to -12db and may also increase output gain of the source from 0db to +18db.
Each of the source input and output adjustments are separate, allowing considerable setup flexibility.
After performing the following setup the audio level should be consistent when selecting the various
audio sources at the Keypad.

Adjusting Input Attenuation

1. From the MRC Setup Mode Options screen (FIG. 5), select Gain/Attenuation to access the MRC
Gain/Attenuation Mode screen (FIG. 10).
FIG. 10 MRC Gain/Attenuation Mode screen
Matrix on-board (Built-in) Tuner (s) have pre-established gain/attenuation settings.
You can not change the gain when the source is an on-board tuner.
2. Select Input Attenuation. This invokes the Input Attenuation Mode screen (FIG. 11):

3. Select a source (1-8) to be adjusted for input attenuation. This selection invokes the Set Input
Attenuation For Source # screen (FIG. 12):
Mi Series Audio Controllers
IR not taught – Error Code # (command was not received, was incomplete or could not be
learned)
IR OK – 99 percent sure (More than 2 commands were received)
IR OK – 75 percent sure (2 commands were received)
IR OK – 50 percent sure (1 command received)
Select [OK] to proceed to the next IR code to be learned.
Some remotes may only send 1 command, in this case the accuracy of the IR learned will
never be better than "50 percent sure", however, the IR will work correctly.
Once all IR codes have been learned, you will be returned to the Program Mode screen where
they can either select another source to program, or "Exit" program mode.
If "IR Not Taught – Error Code #" is received, try re-learning the IR. In most cases, the IR
will be re-learned correctly.
