Key Type

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 (IR SYNC OK) if the transfer is success-
ful. The transmitted audio will then be encrypted and
can only be listened to if the receiver has the matching
encryption key.
The DBu has four options for encryption keys:
• Universal: This is the most convenient and basic
option available, and the default setting on all Lec-
trosonics D2 digital units. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal key. The key does not have to be
generated in the Dhu. Simply set the Lectrosonics
encryption-capable transmitters and receivers to
Universal key type, and the encryption is in place.
This allows for convenient encryption amongst
multiple transmitters and receivers, but is not as
secure as creating a unique key.
• Shared: This key policy is designed for sports
coverage and similar applications where a unique
key provides enhanced security, but multiple
transmitters and receivers can share the same
key. Once generated by the receiver, the key can
be transferred via IR to transmitters or additional
receivers.
• Standard: This key policy provides excellent
security, second only to the Volatile key policy.
Once a unique key is created in the receiver, it can
be transferred via IR only to transmitters, but not
to other receivers. The receiver tracks the number
of times the key is transferred. Once a Standard
key has been transferred 256 times, an alert will
indicate that a new key must be created.
• Volatile: This is the most robust key policy avail-
able. After a unique key is created, it can be trans-
ferred only to transmitters, not other receivers. If
a transmitter is powered off, it must have the key
sent to it again from the receiver. If the receiver is
powered off, a new key must be generated and
sent to the transmitters. In encryption terms, this
is the "one time use" key management policy.

Setup

ProgSw (Programmable Switch Functions)
The programmable switch on the top panel can be con-
figured using the menu to provide several functions:
• (none) - disables the switch
• Mute - mutes the audio when switched on; LCD
will display a blinking "MUTE" and the -10 LED
will glow solid red.
• Power - turns the power on and off
• TalkBk - switches the audio output on the receiv-
er to a different channel for communication with
the production crew. Requires a receiver with this
function enabled.

NOTE: The programmable switch will continue
to operate whether or not settings are locked.
