The DBu 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 receiver). Set
the matching KEY TYPE in the DBu and transfer the
key from the receiver (SYNC KEY) to the DBu via the
IR ports. A confirmation 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 encryp-
tion key.
The DBu 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 receiv-
er and transferred to the DBu, the encryption key
is available to be shared (synced) by the DBu with
other transmitters/receivers 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 encryp-
tion option available. All encryption-capable Lec-
trosonics transmitters and receivers contain the
Universal Key. The key does not have to be gener-
ated by a receiver. Simply set the DBu and a Lec-
rosonics receiver to Universal, and the encryption
is in place. This allows for convenient encryption
25
amongst multiple transmitters and receivers, but not
as secure as creating a unique key.
