Audio Input Jack; Battery Compartment And Thumb Screw; Modulation Leds; Up/Down Arrow Buttons - Lectrosonics SMV-941 Series Quick Start Manual

Power LED Off Feature
In normal operating mode, the UP and DOWN arrow buttons may be used to
turn the PWR LED indicators off and on. This setting does not persist through
a power cycle nor does it affect the LCD backlight.

Audio Input Jack

The Servo Bias input circuitry accommodates virtually every lavaliere, hand-
held or shotgun microphone available, plus line level signals.

Battery Compartment and Thumb Screw

The large knurled thumbscrew is used to release or secure the Battery Com-
partment Cover Plate.

Modulation LEDs

Proper input gain adjustment is critical to ensure the best audio quality. Two
bicolor LEDs will glow either red or green to accurately indicate modulation
levels. The input circuitry includes a wide range DSP controlled limiter to pre-
vent distortion at high input levels.
It is important to set the gain (audio level) high enough to achieve full modu-
lation during louder peaks in the audio. The limiter can handle over 30 dB of
level above full modulation, so with an optimum setting, the LEDs will flash red
during use. If the LEDs never flash red, the gain is too low. In the table below,
+0 dB indicates full modulation (-20 LED just turns red).
Signal Level
Less than -20 dB
-20 dB to -10 dB
-10 dB to +0 dB
+0 dB to +10 dB
Greater than +10 db
AUDIO and FREQ Buttons
The AUDIO button is used to display the audio level and low frequency roll-off
settings. The UP and DOWN arrow buttons adjust the values.
The FREQ Button displays the selected operating frequency and toggles the
LCD between displaying the actual operating frequency in MHz and a two-
digit hexadecimal number that corresponds to the equivalent frequency switch
setting on legacy transmitters.
Pressing both buttons simultaneously enters the standby mode and turns the
unit on and off

UP/DOWN Arrow Buttons

The UP and DOWN arrow buttons are used to select the values on the vari-
ous setup screens and to lock out the control panel.
Antenna
The transmitter uses a whip antenna with a flexible woven, galvanized steel
mesh cable and a standard SMA connector.
