Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption key which is shared with the transmitter during an IR
sync. Transmitters and receivers that share an encryption key form a protected audio path, preventing unauthorized access
from other receivers.
Enable encryption using Wireless Workbench or the receiver front panel. For more details, see the user guide for your receiver.
Encrypting a Single Transmitter to a Single Receiver
From the receiver menu: DEVICE UTILITIES > ENCRYPTION > ON (Auto)
1.
2.
Press ENTER.
3.
Perform an IR Sync to share the encryption key with the selected transmitter.
Removing Encryption
1.
From the receiver menu: DEVICE UTILITIES > ENCRYPTION > OFF
2.
Press ENTER.
3.
IR Sync the transmitter and receiver to clear the encryption key.
Note: If multiple transmitters are encrypted to a single receiver, each transmitter must be IR synced to clear the encryption key.
BN and GN OFFSET
BN OFFSET and GN OFFSET compensate for signal level differences between transmitters that share the same receiver
channel. For normal gain adjustments, use the receiver gain buttons.
Set the offset gain on a low signal level transmitter to match a louder transmitter: IR PRESETS > GOOSENECK / BOUNDARY >
BN OFFSET
IR PRESETS > GOOSENECK / BOUNDARY > GN OFFSET
