Frequently Asked Questions - Audio Link Digital Surround EBODE

What to do if the transmission light does not turn on after powering up?

Check the power adapter and outlet. If possible, measure the adapter voltage. If the transmitter remains off, disconnect and reconnect the DC power.

Why is the sound distorted?

The volume of the transmitter or receiver is too high. Lower the transmitter volume until distortion stops. Set the receiver volume to a comfortable level.

How to properly adjust volume for optimal quality?

1) Set the receiver volume low. 2) Set the audio source to maximum level. 3) Increase the transmitter volume until maximum sound without distortion. 4) Adjust the receiver volume to the desired level.

The range is very short, what to do?

Check that there are not too many obstacles between the transmitter and receiver. Try to place them in line of sight. If obstacles are unavoidable, move the devices closer.

How to reduce interference?

Move away cordless phones or 5.8 GHz Wi-Fi networks. Move or reorient the receiver. Use a surge protector to stabilize the power supply.

Can I connect two receivers with this system?

Yes, you can connect a speaker to the left output of the first receiver and another to the right output of the second receiver. Unused outputs remain free.

The receiver does not turn on, what to check?

Make sure the 24V adapter is plugged in correctly and that the power outlet works. If the problem persists, test with another compatible adapter.

Why are there crackles or audio dropouts?

This may be due to strong interference (5.8 GHz cordless phone, Wi-Fi network). Try changing the Wi-Fi channel or moving the devices. Unstable power supply can also be the cause.

How to connect speakers to the receiver?

Use standard speaker cables (not supplied). Observe polarity (+ and -). Never short-circuit the receiver audio outputs.

The sound is too weak even at maximum volume, what to do?

Increase the output level of your audio source (e.g., TV volume). If the transmitter is connected to a fixed output, use a variable output with an adapter.

2. Introduction

Make your speakers wireless with the ALDS58 and eliminate long speaker cables to your rear speakers. The wireless amplifier receives a 5.8GHz signal which is transmitted in a digital format up to 30 meters away from the transmitter. Wireless Digital Audio at full CD quality due to uncompressed technique. Volume can be adjusted with your existing remote and on both transmitter and receiver to guarantee a perfect sound between your front and rear speaker. Stereo Amplifier with 2x40 Watts RMS Output power per channel.

5. Connecting the transmitter

The transmitter connects either to a standard line-out audio interface via the supplied RCA cable or to a received speaker output via the supplied short speaker cables.

If the transmitter is connected via speaker cables, observe the polarity of the cable connection to ensure that the transmitter will be fed with a correct polarity signal. If one of the cables is switched (reversed), one speaker will receive an opposite polarity signal which will degrade sound performance.

The transmitter can also be connected to other audio outputs by using an appropriate adapter.

Connect the supplied small AC adapter's barrel-shaped plug into the DC 9V jack, and then plug the transformer into a standard AC outlet. We recommend the use of a surge protector to protect the transmitter from power surges.

Do not use both the speaker cables and RCA cable. Do not connect speakers to the transmitter. Do not connect the large AC adapter to the transmitter.

6. Connecting the receiver

Connect the DC power input of the receiver with the supplied large 24 V AC adapter (wallwart). The use of a surge protector is recommended to protect the receiver from power surges which may damage the receiver and connected speakers or may cause audio dropouts.

The receiver connects to regular passive loudspeakers via regular speaker cables (not included). Observe the correct polarity when connecting the speakers.

It is also possible to connect both speakers to separate receivers by using an additional receiver. In this case connect one speaker to the left audio output of the first receiver and the second speaker to the right audio output of the second receiver. One audio output of each receiver will not be used in this case.

Never short circuit any receiver audio output since this may damage the receiver. A clicking noise may be generated during receiver power up. Therefore, it is recommended to connect power to the receiver prior to connecting the speakers.

7. Placing the transmitter and receiver

For optimum reception, the receiver should be placed within the line of sight from the transmitter. If possible, the receiver should be placed right side up with its front toward the transmitter.

The transmitter should be placed at an elevation such that there are no obstacles between the transmitter and receiver (line of sight) in an area where there will be the least amount of traffic. We suggest that you place the transmitter on top of your audio source. Example 1 shows the optimum placement of the transmitter and receiver.

graph LR
    A["Transmitter"] -->|Line of Sight| B["Receiver"]
    B -->|Speaker| C["Speaker"]

Example 1

The receiver can also be placed as shown in example 2. In this case, no line of sight exists and the operating range is reduced.

graph TD
    A["Transmitter"] --> B["Indirect Connection (Reflected signal)"]
    B --> C["Receiver"]
    C --> D["Speaker"]

Example 2

You can mount the receiver vertically by using the 2 screw openings at the bottom of the receiver. If the receiver is mounted vertically, the operating range is reduced compared to mounting the receiver right side up.

The receiver incorporates a directional antenna which prefers signals transmitted toward the front of the receiver. Therefore, the front of the receiver should always be facing toward the direction of the strongest transmitter signal. By properly orienting the receiver, interference from other signal sources can be minimized.

We suggest that you experiment with placement in order to find the best location for the transmitter and receivers.

Note: This product will not work properly from within an enclosed metal cabinet.

8. Operating the transmitter

After powering up the transmitter, the transmit light will go on for approximately five seconds while the transmitter initializes.

After initialization, the transmit light will go out.

Initially, set the transmitter volume control to a middle setting.

Once audio is detected at the audio input, the transmit light will go on and the transmitter will transmit the audio signal.

When audio is no longer detected, the transmitter will go into standby mode after approximately one minute. The transmit light will go out. During standby mode, no signal is transmitted.

9. Operating the receiver

As soon as a valid transmitter signal is received by the receiver, the receiver will output the received audio signal to the speaker outputs. You can change the audio level by adjusting the receiver volume control.

In order to achieve maximum transmission quality, the transmitter volume control should be set to match the audio level of your audio source as follows:

1) Set the receiver volume control to a low level to prevent clipping inside the receiver.
2) Set your audio source to output the maximum audio level that you will encounter during normal operation.
3) Turn the transmitter level control knob to the position that yields maximum audio loudness to the speakers without any clipping (distortion). If the transmitter level is set too low, the dynamics of the transmission are not fully used. If the level is set too high, audio clipping (distortion) will occur inside the transmitter.
4) Turn the receiver volume control to a setting that yields the desired volume from the speakers.

If no audio signal is received for more than 20 minutes, the receiver will go into standby mode (power-down mode).

Either eliminate the interference, locate the base unit of the cordless phone in another room, set the wireless network to use the 5.1 GHz frequency band rather than 5.8 GHz, relocate the transmitter, relocate or reorient the amplifier.Ensure that the power outlet delivers a stable voltage. Very strong surges or voltage fluctuations may cause audio dropouts. Try using a surge protector.
Audio is noisy	Strong interference	See under “Strong Interference” on previous page.
	Transmitter volume control set too low	Adjust the transmitter volume control.
	Audio signal too weak	See under “Audio signal too weak” on previous page.
Transmitter range is extremely short	Strong interference	See under “Strong Interference” on previous page.
