Adjusting Audio Output - Lectrosonics UCR401 Quick Start Manual

Adjusting Audio Output

1.
Install fresh batteries or connect an external power source.
2.
Unless frequency settings have been previously assigned, scan for an
open frequency and set both the receiver and transmitter to that frequency.
3. Connect the audio cable to the receiver's Audio Out XLR jack.
4.
Set the Power ON/OFF switch to ON and verify that the LCD panel activates.
5.
Adjust the transmitter gain so that the voice peaks will cause the audio
modulation indicators on the receiver and transmitter to show full modu-
lation on the loudest peak audio levels. Refer to your transmitter manual
for details. Normal levels should cause the UCR401's audio level icon to
fluctuate fully.
6. Adjust the Audio Output level to match the type of input on your camera
or other sound equipment. Use the LEVEL setup screen and adjust the
level with the SEL Up and Down buttons.
If the output of the receiver is too high, you may hear distortion or com-
pression of the natural dynamics of the audio signal. If the output is too
low, you may hear steady noise (hiss) along with the audio.
Note: The test tone output is especially useful for an exact level match.
With the test tone running, adjust for the maximum desired peak level
using the metering on the connected device.
Locking and Unlocking the UCR401 and UCR411a
Front Panel Controls
The front panel panel controls can be "LOCKED" to prevent accidental
changes being made during operation and handling. Whether locked or
unlocked, the setting persists when the unit is off and also when the batteries
are removed.
To LOCK the Receiver
Press and hold the MENU button until a bar tracks horizontally across the
LCD screen and the word "LOCKED" appears. If the MENU button is released
before the word "LOCKED" appears, the unit will remain UNLOCKED.
In LOCKED state, the use of the MENU and SEL Up/Down buttons are limited
to "view only" and any attempts to change selections will result in a LCD
screen displaying the word "LOCKED." The unit cannot be used for RF scan-
ning when it is set in the LOCKED state. When in a LOCKED state, the pilot
tone bypass toggle is also defeated.
To UNLOCK the Receiver
Press and hold the MENU button until a bar tracks horizontally across the
screen and the word "UNLOCKED" is displayed on the LCD screen. When the
unit is UNLOCKED, all settings can be altered.
The receiver can only be LOCKED or UNLOCKED from any of the main win-
dows. (There are four of them.) Also, it cannot be switched between LOCKED
and UNLOCKED modes when it is in a scanning mode or from other subordi-
nate screens.
