Step 3: Connect Speakers and Wire to the Receiver/Amplifier
A. Connect the wire coming from the speaker wire to the receiver/
amplifier in the following manner based on the system type:
750iR
(see figure 4)
i. Unscrew the red and black caps on the binding
post connectors.
ii. Insert the bare red wire into the red hole that was revealed
by unscrewing the red cap and the black wire into the hole
on the black connector.
iii. Screw the caps back down onto the wires until they
are secure.
iv. Make sure the speaker on/off switch next to the jack is
switched to the “on” position.
780iR
(see figure 5)
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.
B. 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 CNXQ 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.
