Thank you for choosing Senal.
The Senal AWS-24G Advanced Wireless Microphone System delivers accurate and
high-quality 48 kHz audio for two-person shoots, interviews, and broadcasts. Two
transmitters can be deployed with a single receiver to capture dialog and interviews
from 300 feet away. The transmitters are designed for simple, trouble-free operation,
so just turn them on and start recording. The transmitters’ tiny dimensions make them
easy to conceal, and they’re equipped with built-in omnidirectional microphones that
will capture sounds as faint as a whisper. This kit includes two omnidirectional lavalier
microphones for an even closer sound. To ensure flawless audio and to protect
against dropouts, the transmitters can record and store up to 8 GB of audio so you
can download the WAV files to your DAW and edit them individually.
The functionality of the receiver will benefit any shoot. Connect it to a camera,
smartphone, or computer with the included 3.5 mm or USB cables, and bring home
accurate sound that will add production value to any project. Use it to adjust mic gain,
select recording mode, and monitor your audio via the headphone jack.
The kit comes with its own charging case that features a Li-ion battery to charge the
devices while they’re seated, and protect them from dust, moisture, and impacts
during travel.

Charging Case
1. Place the receiver into the RX charging slot, and the transmitters into the TX
charging slots.
2. Use the 3-in-1 cable to connect the charging case’s USB-C port to a USB-A power
source.
3. The power indicator lights will blink sequentially to indicate the units are charging.
Power options include a powered computer port, USB charging hub, or an AC
adapter.
When the case is open during charging, the receiver displays the charging level of
each device. Each bar indicates approximately 25% of the unit’s power.
If the device cannot be charged, reset the device by inserting the included pin into
the reset hole.
Charging Devices Individually
Each device displays the battery level on the screen when they’re powered on.
Use the 3-in-1 cable to connect each device’s USB-C port to a USB-A power source,
like a charging hub or AC adapter.

The transmitters and receiver are paired by default. When the receiver is powered on,
the first transmitter to be powered will send its signal to channel A. The second
transmitter will send its signal to channel B.
If the transmitter is disconnected, re-pair it to the receiver by pressing and holding the Pair button.

Mic Placement
When the internal mic is active, place the
transmitter near the sound source, like a
shirt collar or jacket lapel.
When an external lavalier is active, use the
clip to keep the transmitter concealed and
out of the way.
Due to 2.4 GHz wireless characteristics,
it’s best to keep the transmitters and
receiver in line-of-sight contact. If there’s
any obstruction to the antenna or line of
sight between the transmitters and
receiver, the operating range will decrease.
The transmitters have a line-of-sight operating range of 300 feet.
By default, the internal microphone is active when the transmitter is powered on.
Plug a lavalier microphone into the external mic port to activate it and mute the
internal microphone.
To mute the internal or external microphone, press the Mute button. The mute icon
will appear on the transmitter’s screen. Press the Mute button again to unmute.

Wind Muff
When recording outdoors in a light breeze, the wind muffs will minimize wind noise for a
cleaner recording.
1. Insert the wind muff’s tabs into the transmitter’s locking buckle.
2. Turn the wind muff clockwise to lock it into place.

Recording
The recording feature on the transmitters allows you to record your vocals or speech, and
download it via the USB-C port to a computer or other device.
The transmitter saves a 48 kHz / 16-bit WAV file up to 8 GB.
For continuous recording, the transmitter will create a new WAV file every two hours. Total
recording time is 24 hours. When the 8 GB of memory is full, the transmitter will begin to
overwrite, starting with the oldest file.
To record on the transmitter, follow these steps:
1. Press and hold the Record button until the record icon blinks, and the clock begins
timing the recording.
2. Press and hold the Record button again to end the recording.
Downloading Audio Files to a Computer
Use the white data cable of the 3-in-one output cable to connect the transmitter to a
computer, tablet, or smartphone. The transmitter’s icon will appear as one of the connected
devices. The audio files are in the REC folder. Download the files to your device. Once they’re
copied, you can clear the transmitter’s memory by dragging the transmitter’s audio files to the
trash or recycle bin, and emptying the trash.

Operating Modes
Mono: Sums the signal of receiver channels A and B, and outputs the combined signal to
your recording device.
Stereo: Separates the signals on channels A and B, outputs discretely to separate channels
on your recording device.
Safety: Outputs two mono tracks. One is at the selected gain setting. The other is reduced
by 6 dB. Recording in safety mode is useful for audio with wide volume changes. If you hear
clipping in the original audio, the reduced output of the safety recording will give you clean
audio.
Adjusting the Input Signal Gain
The Output Gain Control buttons adjust the receiver’s output level from -12 to +12 dB.
Mono Mode: The Up/Down buttons change the gain on both channels.
Stereo Mode: Each button controls the gain level for its channel. Press the channel’s button
repeatedly to cycle through the gain level from -12 to +12 dB.
Safety Mode: As you adjust the gain on channel A, the B channel automatically sets its gain
to 6 dB less than channel A.
