Wideband Digital Hybrid
®
Plug-On Transmitter

The HMa improves on those functions and is able to use
less power from the battery by using constant current
sources and current limiters. With this dynamic arrange-
ment the HMa can also supply more than twice the cur-
rent of competing 48 Volt plug on units and provide four
times the current for some very high end 15 Volt micro-
phones.
FREQ Button Settings
Press the FREQ button on the Control Panel to enter
this setup screen. The display will vary depending upon
which StepSize setting is selected. See Selecting Step
Size on page 9.
Note: The default display is in MHz. Pressing
the FREQ button again displays the operating
frequency as a two-digit hexadecimal number
that corresponds to legacy Lectrosonics
products that used two 16-position switches to
set the frequency.
While holding the FREQ button, use the UP or DOWN
arrow buttons to change the frequency.
Note: The operating frequency displayed on the
LCD wraps as it reaches the upper or lower end
of its range.
Block 470/19 Frequency Overlap
Frequencies 486.400 - 495.600 Overlap in Blocks 470 and 19
Block 470 and block 19 overlap each other in the fre-
quency range from 486.400 to 495.600 MHz. Since block
470 starts at a lower frequency than block 19, the hex
codes (and pilot tones) will not match even though the
frequencies are the same in the overlap zone. When
using a transmitter on the A1 band with a block 19
receiver, be sure the transmitter is set to block 19 and
check the hex code on the receiver to make sure it
matches the transmitter.
Call the factory for further questions on this issue.

number
Frequency displayed
in MHz
The operating frequency can be
displayed either in MHz or as a
two-digit hexadecimal number.
The example of the two-digit
display shown here indicates CH
(channel) and 2C as the frequen-
cy.
The frequency can be set with
the unit in standby mode or
when powered up for normal
operation.
Set Up in 25kHz Step Size
Frequency expressed in MHz
The hexadecimal display in the 25 kHz mode will ap-
pear with a decimal sux to indicate the 25 kHz steps.

Lock/Unlock Screen
Simultaneously pressing and holding both the UP and
DOWN arrow buttons during normal operation starts
the LOCK timer. The timer starts at three and counts
down to zero. When the timer reaches zero, the keypad
controls are locked.
The LCD will display the locked condition as long as
the arrow buttons are held, then revert back to the pre-
vious screen when either button is released.
With the controls locked, the AUDIO and FREQ but-
tons can still be used to display current settings. Any
attempt to change a setting by pressing either the UP
or DOWN arrow button will result in an on-screen Loc
reminder that the controls are locked.
NOTE: The control panel can be unlocked by
removing the batteries or using the “dweedle”
tone remote control.
Remote Control with “Dweedle Tones”
Various settings on the transmitter can be adjusted
with special audio tones (“dweedle tones”) delivered to
the microphone. The tones are generated by a smart
phone using the LectroRM app.
LectroRM is a third party application written by New
Endian for iOS and Android smart phones that gener-
ates the control tones for the remote control functions.
The app is available for purchase from the App Store or
Google Play for about $20.
