AUDIO PERFORMANCE & FEATURES

Noise Cancellation & Echo Cancellation

Noise cancellation uses three microphones to pick up 360
degrees of audio and advanced algorithms to monitor the
sounds, adjusting the integrated noise cancellation level to
best match your environment.

In doing so, it suppresses unwanted background noises,
such as crowds, high-winds, sirens and speeding motor
vehicles.

This results in a high level of clarity with clear, natural
sounding speech in both quiet and noisy environments.

Loudness

Dual front-facing speakers provide up to 112 dBSPL of
loudness. Even at 30 cm away from the source the outgoing
audio is measured at 96 dBPhon of loudness.

The audio profile of the LEX L11 is on par with traditional
Land Mobile Radios.

PTT Audio Profile Mode

PTT audio profile mode offers unique audio profiles,
optimized for use with the Motorola Solutions Broadband
PTT application:

● PTT Enhanced Noise Suppression

● Howling Suppression

It is accessible via:
Menu Settings → Sound → LEX Audio Preferences

In addition, user can toggle the PTT Audio Profile ON/OFF
via the Quick Settings panel.

PTT Enhanced Noise Suppression (ENS)

When using the device with Motorola Solutions Broadband
PTT application in a noisy environment, users can enable
PTT Enhanced Noise Suppression (ENS) feature to enhance
the noise suppression capability to ensure clarity of voice
communications.

We have optimized and tuned the audio profile by leveraging
the audio profile used by our APX radios when used in noisy
and mission critical environments.

Note: Works with Motorola Solutions broadband PTT
solution 9.x and above.

AUDIO PERFORMANCE & FEATURES

Howling Suppression

When devices in close proximity are affiliated with the same
talkgroup, a feedback loop can occur. This screeching or howling
noise isn’t just annoying - it can disrupt critical communication
when lives are on the line.

When enabled, the LEX L11 Howling Suppression audio profile
will suppress this unwanted effect, resulting in clear and
uninterrupted conversations. This technology has been
successfully deployed on our LMR devices for many years.

Dynamic Howling Suppression with Motorola Solutions
Broadband PTT application: when enabled, the LEX L11 will
automatically adjust the audio loudness on the receiving
based on the proximity to the transmitting devices to
eliminate unwanted acoustic feedback.

Note: The Howling Suppression audio profile has been
optimised with the Motorola Solutions broadband PTT
application, and not all applications or use cases can take
advantage of the Howling Suppression profile. When used
with a third-party PTT application, Static Howling
Suppression is used.

AUDIO PERFORMANCE & FEATURES

Carry Holster

A traditional belt holster can block the phone’s external speaker
which causes a significant decrease in audio quality making it
difficult to properly hear.

When the LEX L11 is holstered
the outgoing audio is funneled
more effectively in the direction
of your ear making it easier
to hear.

Note: The holster requires purchase with separate Peter Jones
attachments (e.g. belt loop, garment fitting, belt clip). Please
refer to the LEX L11 Accessory Catalogue for more information.
