Encryption Key Management
KeyType
The DCHT has four options for encryption keys: 
• Universal: This is the most convenient encryption 
option available. All encryption-capable Lectroson-
ics transmitters and receivers contain the Universal 
Key. The key does not have to be generated by 
the DCHT. Simply set a Lectrosonics encryption-
capable receiver and the DCHT to Universal, and 
the encryption is in place. This allows for convenient 
encryption amongst multiple transmitters and re-
ceivers, but not as secure as creating a unique key.
NOTE: When the DCHT is set to Universal 
Encryption Key, Make Key, Wipe Key and Share 
Key will not appear in the menu.
• Shared: There are an unlimited number of shared 
keys available. Once generated by the DCHT and 
transferred to an encryption capable receiver, the 
encryption key is available to be shared (synced) by 
the receiver with other encryption capable transmit-
ters/receivers via the IR port. 
• Standard: Standard Keys are unique to the DCHT 
and there are only 255 key instances available to 
be transferred to a receiver. The DCHT is the sole 
source of the Standard Key, and because of this, 
the DCHT may not receive (get) any Standard Keys. 
• Volatile: This one-time only key is the highest level 
of encryption security. The Volatile Key exists only 
as long as the power in both the DCHT Transmitter 
and an encryption capable receiver remains on dur-
ing a single session. If the receiver is powered off, 
but the DCHT has remained turned on, the Volatile 
Key must be sent to the receiver again. If the power 
is turned off on the DCHT, the entire session con-
cludes and a new Volatile Key must be generated 
by the transmitter and sent to the receiver via the IR 
port. Similar to Standard Keys, there are only 255 
key instances to be transferred to a receiver.
MakeKey
When the transmitter key type is set to Volatile, Stan-
dard or Shared, use this menu item to create a key that

This menu item is only available if there is a Key Type
