The DHu, DHu/E01 receives an encryption via the IR
port from a key generating receiver. Begin by selecting
a key type in the receiver and generating a new key
(key type is labeled KEY POLICY in the DSQD receiv-
er). Set the matching KEY TYPE in the DHu, DHu/E01
and transfer the key from the receiver (SYNC KEY)
to the DHu, DHu/E01 via the IR ports. A confirma-
tion message will display on the receiver display if the
transfer is successful. The transmitted audio will then
be encrypted and can only be listened to if the receiver
has the matching encryption key.
The DHu, DHu/E01 has three options for encryption
keys:
• Standard: This is the highest level of security.
The encryption keys are unique to the receiver
and there are only 256 keys available to be
transferred to a transmitter. The receiver tracks
the number of keys generated and the number of
times each key is transferred.
• Shared: There are an unlimited number of
shared keys available. Once generated by a re-
ceiver and transferred to the DHu, DHu/E01, the
encryption key is available to be shared (synced)
by the DHu, DHu/E01 with other transmitters/re-
ceivers via the IR port. When a transmitter is set
to this key type, a menu item named SEND KEY
is available to transfer the key to another device.
• Universal: This is the most convenient en-
cryption option available. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal Key. The key does not have to be
generated by a receiver. Simply set the DHu,
DHu/E01 and a Lecrosonics receiver to Univer-
sal, and the encryption is in place. This allows for
convenient encryption amongst multiple transmit-
ters and receivers, but not as secure as creating
a unique key.
