senal AWS-24G Advanced Dual 2.4GHz Wireless Microphone System User Guide

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.

Precautions

• Please read and follow these instructions, and keep this manual in a safe place.

Charging

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

Pairing the Transmitters and Receiver

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.

Operating the Transmitter (TX)

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.

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.

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 the Receiver (RX)

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.

Analog Audio Output

Use the 3.5 mm TRS to TRS cable to connect the receiver’s output jack to a camera.
Use the 3.5 mm TRS to TRRS cable to connect the receiver’s output jack to a smartphone or a computer.
Plug headphones into the headphone jack to monitor the audio.

Digital Audio Output

Use the 3-in-1 audio cable, plus the necessary plug adapters (not included), to connect the receiver to a smartphone, tablet, or computer, and record your audio
