Frequently Asked Questions - LV Sub AUDIO PRO

How to connect the LV Sub to an existing Audio Pro network?

Make sure the House Code and the zone of the LV Sub match those of your other Audio Pro speakers. Plug the subwoofer into a power outlet; the connection is established automatically.

What to do if the LV Sub LED is red?

The red LED indicates that no wireless connection is established or that the device is in standby. Check that the TX100 transmitter is turned on and that the House Code is set correctly.

How to adjust the volume of the subwoofer?

Use the Level button located on the back of the LV Sub for manual adjustment. You can also synchronize the volume with other speakers via the remote control by selecting the corresponding zone (A, B, or C).

Can I use the LV Sub with a wired stereo system?

Yes. Connect the subwoofer output of your amplifier to the line input of the LV Sub using an RCA cable. Note: in wired mode, the subwoofer is excluded from the wireless network.

How to add multiple LV Subs to the wireless network?

You can add an unlimited number of LV Subs, provided they are within range of the transmitter. Set the same House Code on all subwoofers; they will receive signals simultaneously.

Where to place the subwoofer for best sound?

For optimal bass, place the LV Sub near a wall or in a corner. Test different locations as corner placement can reinforce bass.

How to change the House Code on the LV Sub?

The House Code switch is located on the rear panel. Set it to the same value (1, 2, or 3) as your TX100 transmitter or other speakers.

How to change the zone on the LV Sub?

The zone switch is located on the back. Choose A, B, or C to assign the subwoofer to a specific zone. Each zone can have its own volume controlled by the remote.

What to do if the subwoofer sound is too weak or too loud compared to other speakers?

You can manually adjust the bass volume with the Level button on the back. To automatically synchronize levels, perform the synchronization procedure described in the manual (set the LV Sub volume to mid-range, then use the remote to adjust the zone volume).

How to clean the LV Sub?

Unplug the device and clean it with a dry cloth. Do not use liquid or abrasive products. Avoid blocking the ventilation openings.

JOIN EXISTING AUDIO PRO NETWORK

If you already have one of Audio Pro's wireless LV loudspeakers and a TX100 wireless transmitter, the LV-SUB automatically connects to your network. Simply set the same House Code and zone that your existing LV loudspeakers use and connect the LV-SUB to the power socket.

CONNECTING THE LV-SUB TO AN EXISTING NETWORK FOR THE FIRST TIME:

In order to synchronise volume levels so that the LV-SUB plays at the same level as other loudspeakers in the same zone and House Code:

1. Ensure that all the loudspeakers in the zone (A, B or C), including the LV-SUB, are switched on and set to the same zone and House Code (all LV loudspeakers are set to zone A as default).
2. Set the Level on the rear of the LV-SUB to the middle position (0).
3. Raise or lower the volume using the remote control's zone volume: A, B or C. (Point the remote control at the receiving loudspeaker, e.g. LV-2 loudspeaker)
4. The volume levels for all units in the zone should now be synchronised.

If you do not synchronise the levels, the LV-SUB may emit too little or too much bass.

(You can manually raise or lower the bass volume if you desire more or less bass.

The controls for this can be found on the rear of the LV-SUB.)

Note:

• The LV-SUB volume is controlled in the network using the same remote control as for Audio Pro's wireless LV loudspeakers.
• Manual default settings, such as subwoofer volume and crossover frequency, can be found on the rear of the LV-SUB.

ANALOGUE CONNECTION TO THE STEREO/RECEIVER

You can create an analogue connection from the LV-SUB to any stereo/receiver equipped with a sub-output. Connect with a cable from the sub-output to the Line In on the rear of the LV-SUB

Note: If LV-SUB is connected by cable, it will be excluded from wireless network.

ADD MORE LV-SUBs TO THE WIRELESS NETWORK

You can add an unlimited number of LV-SUB subwoofoers to the network, as long as they are positioned within the transmitter's range

All the LV-SUBs will receive signals from transmitters using the same House Code.

You can have multiple subwoofoers in one room or individual subwoofoers in several rooms.

PLACEMENT OF THE SUBWOOOFER

Since the LV-SUB functions wirelessly, its placement is simple. Just connect it to the power socket and place it within range of the transmitter.

For optimal bass reproduction, the subwoofer should be placed close to a wall or in a corner.

Corner placement can result in a powerful bass, so try different places until you are satisfied with the bass reproduction.

HOUSE CODE AND ZONE

An Audio Pro audio network can be extended to provide sound in several rooms, or multiple loud-speakers in the same room. But you may not always want to have the same volume in all rooms. To solve this, you can divide each House Code up into a total of 3 different zones. Each zone is allocated its own volume. This is convenient if you wish, for example, to have a certain volume level in the living room and a different volume in the kitchen. You can have as many LV-SUBs in each zone as you wish, or just the one.

The LV-SUB is integrated as a natural part of the Audio Pro network.

HOUSE CODE 1

Speakers and transmitter use same house code.

Example with Living LV2 speakers.

Zone B

HOUSE CODE 2

Note that:

1. Each House Code (1, 2 and 3) can be divided up into a maximum of 3 zones (A, B and C).
2. You can allocate an unlimited number of loudspeakers to each House Code, and as many as you wish to each zone. A zone does not need to be restricted to a single room - it can be the whole floor or a department (within range of the transmitter)

HOW TO CHANGE HOUSE CODE ON THE LV-SUB

The House Code switch is located on the rear panel of the LV-SUB.

Set the same number (1, 2 or 3) as on the TX100 transmitter.

The House Code can be likened to a channel via which wireless signals are transmitted.

Within the network, music can be sent simultaneously from 3 different audio sources.

The Zone switch is located on the rear panel of the LV-SUB.

Set the same letter (A, B or C) as the other loudspeakers you wish to have in the same zone.

A House Code (channel) can be divided up into a total of 3 zones. You can control the volume level of these zones individually using the remote control. You can, for example, have one volume level in the kitchen, another in the living room, and a third in the bedroom.
