Speaker Installation Instructions
780iR (see figure 4)
i. Insert the 1/4” plug into the SPEAKER OUTPUT 1 jack on the
back of the receiver/amplifier.
ii. The speaker volume knob should be left at the 12:00 position
for most applications.
iii. Make sure the corresponding speaker on/off switch on the
front panel is set to the “on” position.
C. Speaker wire should be secured to the wall and concealed if desired
with wire mold.
Step 4: Equalization
A. Each receiver/amplifier includes an 8-band equalizer that allows
users to fine-tune their classroom based on different room
characteristics. Figure 5 shows the factory recommended settings
for the NXQ speaker. Since all rooms are different, this is only
meant as a starting point and may require some adjustment.
B. The ideal sound is a crisp, clear sound with no feedback. Volume
levels should be set to a point you can barely hear your own voice.
The goal is to try to replicate the sound of your voice as if the
child is sitting directly in front of you, not to amplify your voice at
high volumes. Because of the classroom size and constant
proximity to the speaker, the system can product feedback
(squealing) if the volume level is set too high.
C. Return to “Step 4: Receiver/amplifier” of the install section of
the user manual to complete the remaining steps of the
system installation.
