AP-60 Product Update
Battery Update
The AP-60 pendant microphone includes rechargeable batteries and a charger. The rechargeable batteries
replace the LR6 (alkaline) batteries mentioned in the Installation Guide and User’s Guide. For best results, be
sure to use the rechargeable batteries in the pendant microphone. Refer to the instructions included with the
rechargeable batteries and charger for usage information.
Recommended Ceiling Plate Kits
The AP-60 is designed to work with the following Epson ceiling plate kits:
ELPMBP01 (adjustable suspended ceiling channel kit)
ELPMBP02 (false ceiling plate kit)
Refer to the ceiling plate kit manual for installation instructions.
Reducing Microphone Feedback
Try the following solutions to reduce microphone feedback (howling):
Move the microphone at least three to four feet away from the AP-60 speakers.
Adjust the
Gain wheel on the pendant microphone until the white line is next to Up, but still
visible. Adjust the
Microphone and Line gain control knobs on the AP-60 audio control panel
to the 12 o’clock position (approximately 50%). Then adjust the AP-60 master volume using the
remote control until you achieve the desired volume.
Note
If necessary, the Microphone gain control knobs can be adjusted to the 1 o’clock
position, and the Line gain control knobs can be set to the 2 o’clock position. Using a
higher microphone gain setting will increase the chance of microphone feedback.
If youre still experiencing feedback after trying the solutions above, turn on
the AP-60 Anti-Feedback feature (see below).
Using the AP-60 Anti-Feedback Feature
Follow the steps in the Installation Guide to remove the audio control panel from the AP-60.
1 Set the
ANTFD switch on the back of the audio control panel to one of the following positions:
LOW: Use this setting if the gain and volume settings are set properly and microphone feedback occurs
occasionally.
HIGH: Use this setting if the gain and volume settings are set properly and microphone feedback occurs
frequently. Using this setting with a Line gain set to the 3 o’clock position or higher may reduce sound
quality.
2 Follow the steps in the Installation Guide to reinstall the audio control panel.
