DBu, DBu/E01 Features and Functions

Programmable Switch

The transmitter can also be congured as a “one button” device by

locking the ability to make changes with the keypad, and conguring

the top panel switch as either power on/o or a mute function.

Modulation Indicator LEDs

When the transmitter is set to MUTE, the -10 Modulation Indicators

LED will glow solid red. Otherwise, the -10 Modulation Indicators LED

will glow solid green when transmitter is on.

Belt Clips

The wire belt clip may be removed by pulling the ends out of the holes

in the sides of the case. Be sure to have a rm grip to avoid scratching

the surface of the housing.

An optional spring-loaded, hinged belt clip (model number BCSLEBN)

is also available. This clip is attached by removing the plastic hole cap

on the back of the housing and mounting the clip with the supplied

screw.

IR (infrared) Port

The IR port is available on the top of the transmitter for quick setup

using a receiver with this function available. IR Sync will transfer the

settings for frequency from the receiver to the transmitter.

Battery Installation

The transmitter is powered by two AA batteries. We recommend using

alkaline, lithium, or rechargeable batteries for longest life.

The battery status circuitry compensates for the dierence in voltage

drop between alkaline and lithium batteries across their usable life, so

it’s important to select the correct battery type in the menu.

Because rechargeable batteries run down quite abruptly, using the

Power LED to verify battery status will not be reliable. However, it is

possible to track battery status using the battery timer function avail-

able in the receiver.

Push outward on the battery compartment door and lift it to open.

Slide door out to release catch

Lift door to open

Insert the batteries according to the markings on the back of the hous-

ing.

If the batteries are inserted incorrectly, the door will close but the unit

will not operate.

The battery contacts can be cleaned with alcohol and a cotton swab,

or a clean pencil eraser. Be sure not to leave any remnants of the cot-

ton swab or eraser crumbs inside the compartment.

Battery Status LED Indicator

Alkaline, lithium or rechargeable batteries can be used to power the

transmitter. The type of batteries in use are selectable in a menu on the

LCD.

When alkaline or lithium batteries are being used, the LED labeled BATT

on the keypad glows green when the batteries are good. The color

changes to red when the they are nearing the end of life. When the LED

begins to blink red, there will be only a few minutes remaining.

The Power/Function LED on the top panel will mirror the keypad LED

unless the programmable switch is set to Mute, and the switch is

turned on.

The exact point at which the LEDs turn red will vary with battery brand

and condition, temperature and power consumption. The LEDs are

intended to simply catch your attention, not to be an exact indicator of

remaining time.

A weak battery will sometimes cause the Power LED to glow green im-

mediately after the transmitter is turned on, but it will soon discharge to

the point where it will turn red or the unit will turn o completely.

Rechargeable batteries give little or no warning when they are depleted.

If you wish to use these batteries in the transmitter, the most accurate

way to determine runtime status is by testing the time provided by a

particular battery brand and type, then using the BatTime function to

determine remaining runtime.

NOTE: Refer to the Main Menu and Setup Section of your

manual for BatTime details.

If the power button is released, or the top panel

switch is turned back on again before the moving bar

progresses, the unit will remain turned on and the LCD will return to the

same screen or menu that was displayed previously.

NOTE: If the programmable switch is in the OFF position, power can

still be turned on with the power button. If the programmable switch is

then turned on, a brief message will appear on the LCD.

When you release the but-

up in either the operating or the standby mode, press MENU/SEL on

the keypad to enter a menu structure on the LCD. Use the and ar-

row buttons to select the menu item. Then press the MENU/SEL button

to enter the setup screen.

Gain

Gain can be set, from -7 to +44, by using the and arrow buttons.

Adjusting the Input Gain

The two bicolor Modulation LEDs on the top panel provide a visual indi-

cation of the audio signal level entering the transmitter. The LEDs will

glow either red or green to indicate modulation levels as shown in the

following table.

Signal Level -20 LED -10 LED

Less than -20 dB O O

-20 dB to -10 dB Green O

-10 dB to +0 dB Green Green

+0 dB to +10 dB Red Green

Greater than +10 dB Red Red

NOTE: Full modulation is achieved at 0 dB, when the “-20” LED

ﬁrst turns red. The limiter can cleanly handle peaks up to 30 dB

above this point.

It is best to go through the following procedure with the transmitter

in the standby mode so that no audio will enter the sound system or

recorder during adjustment.

1) With fresh batteries in the transmitter, power the unit on in the

standby mode (see previous section Powering On in Standby

Mode).

2) Navigate to the Gain setup screen.

-40 -20 0

Gain

3) Prepare the signal source. Position a microphone the way it will

be used in actual operation and have the user speak or sing at

the loudest level that occur during use, or set the output level of

the instrument or audio device to the maximum level that will be

used.

LECTROSONICS, INC.10

4) Use the and arrow buttons to adjust the gain until the –10

dB glows green and the –20 dB LED starts to icker red during

the loudest peaks in the audio.

5) Once the audio gain has been set, the signal can be sent through

the sound system for overall level adjustments, monitor settings,

etc.

6) If the audio output level of the receiver is too high or low, use

only the controls on the receiver to make adjustments. Always

leave the transmitter gain adjustment set according to these

instructions, and do not change it to adjust the audio output level

of the receiver.

Rollo (Low Frequency Roll-o)

The low frequency audio roll-o is adjustable to optimize performance

for ambient noise conditions or personal preference.

Low frequency audio content may be desirable or distracting, so the

point at which the roll-o takes place can be set to 20, 35, 50, 70, 100,

120 or 150 Hz.
