Frequently Asked Questions - Audio Anywhere 725 MARMITEK

How to pair the transmitter and receiver?

Make sure both devices are turned off. Press and hold the power button on the transmitter for 2 seconds until the red/blue LED flashes slowly. Then briefly press the power button on the receiver. The blue LEDs stay on when pairing is successful. If the LED flashes quickly, repeat the process within 20 seconds.

What to do if there is no sound on my audio system?

Check that the audio cable is properly connected to the AUX input of your audio system and that the corresponding input is selected. Make sure the volume on the transmitter or receiver is not too low. Increase the volume on the audio source and on the receiver.

Can I connect multiple receivers to a single transmitter?

Yes, you can pair up to 16 receivers to a single transmitter. Follow the pairing procedure for each additional receiver.

The sound is not synchronized with the picture on my TV. What to do?

To avoid audio lag, connect the transmitter directly to your TV's audio output rather than to a set-top box or satellite receiver. Use the TV's headphone output to disable the built-in speakers and control the volume with the TV remote.

Can I connect passive speakers directly to the receiver?

No, the receiver can only power active speakers (with built-in amplifier) or passive headphones. For passive speakers, you need to use a separate amplifier.

How to recharge the receiver battery?

Connect the provided micro USB cable to the receiver and plug the USB power adapter into a power outlet. The red LED flashes slowly during charging. Full charging takes about 2 hours and the LED turns off when the battery is full.

What is the maximum range of the Audio Anywhere 725?

In open field, the range can reach 40 meters. Through walls and ceilings, the range is about 10 meters. You can use a signal amplifier to extend the range.

Can I use the USB cable from the adapter on my TV or amplifier?

Yes, you can plug the transmitter or receiver into a USB port of your TV or amplifier. This allows automatic power on/off with the host device (auto power on).

What to do if pairing fails?

Make sure the power adapter is plugged in and the LED is on or flashing. Check that the distance between the devices does not exceed 10 meters and there are no major obstacles. If the problem persists, put the transmitter in pairing mode (long press 2 seconds) and repeat the procedure within 20 seconds.

How to adjust the volume?

Use the + and - buttons on the transmitter to adjust the volume of all connected receivers. You can also adjust the volume individually on each receiver using its own buttons.

3 Your product

3.1 Introduction

Congratulations on your purchase of the Marmitek

Audio Anywhere 725. The Audio Anywhere 725 consists of a transmitter and a receiver. The signal is transmitted at 2.4GHz and can therefore go through walls and ceilings.

The transmitter/receiver can be used to transmit (stereo) audio signals wirelessly.

• Digital Wireless Audio sender
- Wirelessly enjoy music and TV audio.
- Wirelessly send your TV's or computer's audio to your stereo system, speakers or headphones.
- Listen to the music you are playing in the living room and in other rooms (e.g. kitchen/conservatory) simultaneously.
- Digital audio transmission in HD quality via improved 2.4GHz interference-free technology.
- Ideal as a portable solution due to the receiver's built-in battery and dedicated volume control.
- Multiple receivers can be connected to one transmitter.
- Use secured pairing to use multiple sets (up to 6) in the same surroundings.

Via the Audio Anywhere 725, you can playback TV audio or music on your audio system, without using cables to connect your audio source to the audio system. The audio source could, for example, be a PC or laptop, or a TV. You can then use the audio source to select the music and adjust the volume on the transmitter or receiver, without having to walk to your audio system.

The receiver has a built-in battery, so you can, for example, also make your wired headphones or active speakers wireless.

The Audio Anywhere 725 has a range of approx. 40 metres, enabling you to enjoy your audio in the same or adjoining room without limitations.

4 Getting started

Please take the following steps before using the product:

• Installing the transmitter.
- Installing the receiver.
- Connecting the transmitter and receiver.
- Setting the volume.
- Enjoy!

We will now explain this step by step.

4.1 First use

The Audio Anywhere 725 receiver has a built-in rechargeable battery.

Upon first use, we recommend that you fully charge the battery first. To do this, use the included USB cable and connect it to the supplied adapter. During charging, the red LED will flash slowly. It is normal for the first charge to take about 2 hours. Once the battery of the Audio Anywhere 725 receiver is fully charged, the red LED will switch off.

4.2 Installing the transmitter

Any audio source can be connected to the transmitter such as a TV, computer or audio system.

Connect the mini jack plug to, for example, the headphones jack of your TV, smartphone or radio/CD player.

1. Connect the adapter to the micro USB port and plug the adapter into the wall socket.
2. Press the on/off button. The blue LED will now start to flash slowly.
3. Let your audio source produce sound.

4.3 Installing the receiver

1. Connect the mini jack plug (jack out) to, for example, the AUX IN of an active speaker, headphones or a radio/CD player.

2. Connect the adapter to the micro USB port and plug the adapter into the wall socket. The red LED flashes slowly when the battery is charging.

3. Press the on/off button. The Audio Anywhere 725 receiver will now switch on and the blue LED will flash slowly. (The red LED flashes occasionally when the battery is still charging.)

4.4 Pairing the transmitter and receiver

Upon first use, the receiver must be paired with the transmitter.

Make sure the transmitter and receiver are switched off.

1. Press and hold the transmitter's on/off button for 2 seconds. The red/blue LED will now start to flash. The transmitter is now in pairing mode for 20 seconds.
2. Shortly press the receiver's on/off button. The red/blue LED will now start to flash, after which the blue LEDs on the transmitter and receiver will light up continuously to indicate successful pairing. (If the LEDs continue to flash rapidly, the transmitter was probably in pairing mode for more than 20 seconds, cancelling the pairing. You will then need to put the transmitter into pairing mode again and re-try pairing the transmitter and receiver.)

4.5 Setting the volume

On the transmitter, you can adjust the volume to all receivers using the + and - buttons.

On the receiver, you can adjust the volume per receiver.

5 Connection options transmitter

The transmitter features the following connection options:

5.1 Analogue input

Used to connect any analogue output such as an MP3 player, smartphone, TV or audio system.

5.2 Digital Toslink input

Used to connect the Toslink output of your audio system or TV. Make sure that the Toslink setting on your audio system or TV is set to stereo.

5.3 USB input

Used to connect your PC's USB connection, in order to use it as an audio output.

6 Additional receiver

Additional receiver for your Audio Anywhere 725.

An additional receiver allows you to receive the transmitter's signal at multiple locations in the home.

You can connect up to 16 receivers to 1 transmitter.

Follow the instructions in chapter 4.4 to add an additional receiver.

7 Signal booster

The transmitter and receiver have an indoor range of about 10 metres, through walls and ceilings.

If that is insufficient, you can purchase an additional set and connect the receiver to the transmitter to act as a signal booster. In this situation, you connect the first transmitter to the first receiver. Connect the audio output of the first receiver to the audio input of the second transmitter, and connect the second transmitter to the second receiver. You now have a range of 20 metres. You can repeat this as many times as necessary to cover the required distance.

9 Frequently asked questions (FAQs)

I cannot pair my Audio Anywhere 725.

Please check the following:

1. Ensure that the mains adapter is connected and the LED is lit or flashing.
2. Make sure that the distance between the transmitter and receiver does not exceed 10 metres and there are no major obstacles between them.

There is no sound coming from my audio system

• Make sure that the audio cable is connected properly (AUX IN), the correct input is selected on your audio system and the volume of your audio system is set to the desired level.
• Check that the volume on the transmitter or receiver is not set to low.

I have paired my TV's audio wirelessly with my audio system, but the sound is not in sync with the video.

For best results, connect the Audio Anywhere 725 transmitter to your TV's audio output, instead of the audio output of your set-top box or satellite receiver.

Connecting the transmitter to the headphone output turns off your TV speakers and allows you to continue using your TV's remote control to control the volume through the Audio Anywhere 725.

Can I connect my speakers to the receiver directly?

In order to hear sound or music, connect the receiver to an amplifier with separate (built-in) speakers or so-called active speakers (with built-in amplifier). You cannot connect passive speakers directly to the receiver. You can, however, connect passive headphones to the receiver.

Can I also connect my transmitter/receiver's USB cable to a USB connector of, for example, my amplifier or TV?

Yes, you can. The transmitter will then automatically switch on and off, in line with the amplifier or TV. (auto power on)
