Special Speaker Connections
There may be cases where you want to install more than four speakers (e.g., the room is very large) or connect
speakers in series (e.g., to save cable length). Here’s how to do it:
standard four-speaker setup
930R speaker terminals
teacher
speaker cable hookup
(back of each speaker)

Tip
High-band EQ adjustment
In the event you experience acoustic feedback, have someone stand in the area
of maximum feedback with the mic and receiver turned on. A second person
should then adjust the Hi-band EQ control (located on the left side of the receiv-
er) in a counter-clockwise rotation using a flat blade screwdriver, until the feed-
back disappears or is significantly reduced.
Step 6:
Turn it on and test it
Estimated time for this step: 5 minutes
It’s important to confirm that everything is working before packing up your tools. Take a few moments to
test your work.
1. Use the following baseline settings to start:
All volume controls at setting 2 to 3
OptiVoice at Low
2. Put on the transmitter / microphone and turn it on
3. Turn on the receiver
4. Walk, talk, and listen to the sound quality (Find another person to
help you with this step: It’s difficult to assess your own voice)
5. Try to find any areas where the receiver is not picking up your sig-
nal (see Frequently Asked Questions if this happens)
6. Try to find any areas where you experience acoustic feedback
(squealing) (see
Tip below if this happens)
Ask another person to assess volume levels
from front and back of room while you speak
