Lectrosonics UDR700, Instruction Manual

Page: 21 / 36

Encrypted Digital Wireless System
Note: Each transmitter uses a different Encryption
Cable. (See Encryption Key Cables.)
16) Press the SELECT Up button on the UDR700 to
send the encryption key to the transmitter. Depend­
ing on the transmitter, the Power LED on the UT700
or the two Modulation LEDs on the UM700 blink to
confirm receipt of the new key.
Level 1: 1 blink
Level 2: 2 blinks
Level 3: 3 blinks
Note : In Security Levels 1 and 2, you may program
as many transmitters as you like to match the
receiver. Repeat steps 15 and 16 for each
transmitter. This will transmit the same encryption
key to each transmitter; however, once you leave
this prompt, this particular encryption key can
never again be sent out of the Security jack to a
transmitter. A new encryption key will have to be
created. In Security Level 3, each encryption key
may be sent to only one transmitter.
17) Depending on the unit, hold the microphone for the
belt pack transmitter or hold the hand held transmit­
ter in the same position that it will be used in actual
operation.
18) While speaking or singing at the same voice level
that will actually be used, observe the Audio Level
LEDs. Adjust the Audio Level control until the -20
LED occasional blinks red and the -10 LED glows
steady green.
Signal Level -20 LED -10 LED

-20 dB to -10 dB Green Off

Note: Different voices will usually require different
settings of the AUDIO LEVEL control, so check
this adjustment as each new person uses the
system. If several different people will be using the
transmitter and there is not time to make the
adjustment for each individual, adjust it for the
loudest voice.
Note: In the UT700, if you find that the Audio Level
control is set to minimum and the -20 LED still
glows green, then adjust the preamp level control
located under the microphone wind screen. (See
VARIMIC™ CONTROLS.) If you adjust the
preamp level control, you will need to repeat steps
19 and 20.
19) If you are using the UT700 hand held microphone,
replace the Battery Compartment Cover.
20) Once the transmitter gain has been adjusted, the
audio levels for the rest of the system can be set.
Set the UDR700 Analog Audio Output Control to
midrange.
Notes: The transmitter Audio Level Control should
not be used to control the volume of your sound
system or recorder levels. This gain adjustment
matches the transmitter gain with the user’s voice
level and microphone positioning.
Note: The UDR700 receiver needs at least 5 uV of
RF signal to begin operating - this is the
approximate squelch threshold. Between 5 uV
and 10 uV, reception will be marginal and brief
gaps in the audio may occur if the receiver
squelches. Check to see that at least the lowest
four RF LEVEL LEDs stay lit when the transmitter
is turned on.
21) Operate the wireless system and fine tune the
receiver analog audio output level as required by
your equipment. The input levels on different
equipment vary. Try different settings of the Analog
Audio Output Control to listen to the results. If the
output of the receiver is too high, you may hear
distortion or a loss of the natural dynamics of the
audio signal. If the output is too low, you may hear
steady noise (hiss) along with the audio.
