Setting Bass and Treble
Adjust the MPA 152 Plus bass and treble as follows:
1.Use the Bass potentiometer to increase or decrease the bass shelving ±10 dB at 80 Hz and below.
2.Use the Treble potentiometer to increase or decrease the treble shelving ±10 dB at 10 kHz and above.
NOTE: Turning the Bass or Treble potentiometers counterclockwise will decrease the output at the specified frequencies. Turning the potentiometers clockwise will increase the output. When the potentiometer is in the center, flat response is achieved.

Figure 9. Typical Application for the MPA 152 Plus, Using Remote Control
AUsing the IR remote for the projector — When using a projector with variable audio outputs, connect the projector audio output to the MPA 152 Plus audio input. Use the IR remote for the projector to control the volume of the projector, which effectively controls the volume of the MPA 152 Plus.
BExtron volume controllers — Extron provides a range of volume and mute controllers for use with a projector that lacks variable audio outputs. These options control the MPA 152 Plus volume directly (see Wiring for remote control on page 7).
CUsing a MediaLink Controller — For a projector with variable audio output, connect the projector audio output to the MPA 152 Plus audio input. Use a MediaLink controller to adjust the volume of the projector via
