Q: How to increase the volume of the Surround zones on the Auna AMP4000 DAB?

The Auna AMP4000 DAB has 4 independent zones (Z1 to Z4) with individual volume control. Zones 3 and 4 are typically used for surround speakers. Here’s how to increase their volume: Via the front panel Press the ZONE button on the front of the device to select zone 3 or zone 4 (your Surround zones) Turn the MULTI knob to increase the volume of that zone Repeat for the other surround zone if necessary Via the remote control Press the Z3/Z4 button to select the desired zone Use the +/- buttons to increase or decrease the volume Each zone has its own speaker output with 2 screw terminals (impedance 6-16 Ω). For optimal positioning of the surround speakers, place them about 2 meters above the floor, behind your listening area.

Q: How to connect external speakers to the Auna AMP4000 DAB?

The Auna AMP4000 DAB has 4 independent zones (Z1, Z2, Z3, Z4), each equipped with terminal blocks to accommodate a pair of stereo speakers. Here’s how to proceed: Wiring Steps Turn off the device before connecting the speakers Check the impedance of your speakers: they must be between 6 and 16 Ω Observe the polarity : connect the red cable (+) to the positive terminal and the black (-) to the negative terminal of each block. Reversing them causes sound distortion Connect one stereo pair per zone : the left and right speakers of the same pair must be connected to the same zone (Z1, Z2, Z3, or Z4) to maintain the stereo effect Isolate the bare wires : ensure that the exposed wires do not touch each other or contact any metal parts of the device Turn the amplifier back on You can independently manage the volume of each zone using the provided infrared remote control. Also, make sure to maintain at least 8 cm of space around the device and not block the ventilation openings.

Question 1

How to increase the volume of the Surround zones on the Auna AMP4000 DAB?

Accepted Answer

The Auna AMP4000 DAB has 4 independent zones (Z1 to Z4) with individual volume control. Zones 3 and 4 are typically used for surround speakers. Here’s how to increase their volume:

Via the front panel

Press the ZONE button on the front of the device to select zone 3 or zone 4 (your Surround zones)
Turn the MULTI knob to increase the volume of that zone
Repeat for the other surround zone if necessary

Via the remote control

Press the Z3/Z4 button to select the desired zone
Use the +/- buttons to increase or decrease the volume

Each zone has its own speaker output with 2 screw terminals (impedance 6-16 Ω). For optimal positioning of the surround speakers, place them about 2 meters above the floor, behind your listening area.

Question 2

Why is the right speaker connected to the same amplifier not producing any sound?

Accepted Answer

This problem usually occurs when the right speaker is not properly configured or connected. Here are the checks to perform on your Auna AMP4000 DAB:

1. Check the terminal connections

The Auna AMP4000 DAB has 4 zones, each with 2 terminal clips for the speakers. Make sure that:

The cables of the right speaker are properly inserted into the terminal clips (clips must be tightly secured)
The cables are not detached or partially inserted
The terminals themselves are not damaged or blocked

2. Check the polarity of the cables

The impedance must be between 6 and 16 Ω. Also check the polarity by following the color code:

Red (+) cable connected to the positive terminal
Black (-) cable connected to the negative terminal

A reversal of polarity will prevent the speaker from functioning properly.

3. Check the channel balance

Access the balance settings via the MENU button and the MULTI knob. Ensure that the balance control is not completely shifted to the left, which would prevent the right channel from producing sound.

4. Check the zone volume

Press the ZONE button (front panel) to select the zone corresponding to your right speaker (Z1 to Z4), then adjust the volume with the MULTI knob. You can also use the Z1/Z2 or Z3/Z4 buttons on the remote control with the +/- to increase the volume.

After these checks: turn off the device, leave it for 10 seconds, then turn it back on. Test the sound with a different source (DAB radio, auxiliary, or Bluetooth) to see if the problem persists.

Question 3

Should the left and right speakers of the same pair be connected to the same zone or to different zones?

Accepted Answer

No, a pair of stereo speakers (left and right) must always be connected to the same zone.

The Auna AMP4000 DAB has 4 independent zones (Z1, Z2, Z3, Z4), each equipped with its own speaker outputs with individual volume control. Each zone has speaker terminals with a required impedance of 6-16 Ω.

Correct Configuration

Connect the left speaker to the left terminals of the same zone
Connect the right speaker to the right terminals of that same zone

The 4 zones are used to connect different pairs of speakers in different rooms (for example: Zone 1 in the living room, Zone 2 in the kitchen, Zone 3 in the bedroom, Zone 4 in the office).

Why no separation

If you connected the left speaker to one zone and the right to another, you would lose the stereo effect in the first zone and the audio would be out of sync. Also, make sure that the polarity of the cables is correct (connect “+” to “+” and “-” to “-”) to avoid sound distortion.

Question 4

How to connect external speakers to the Auna AMP4000 DAB?

Accepted Answer

The Auna AMP4000 DAB has 4 independent zones (Z1, Z2, Z3, Z4), each equipped with terminal blocks to accommodate a pair of stereo speakers. Here’s how to proceed:

Wiring Steps

Turn off the device before connecting the speakers
Check the impedance of your speakers: they must be between 6 and 16 Ω
Observe the polarity: connect the red cable (+) to the positive terminal and the black (-) to the negative terminal of each block. Reversing them causes sound distortion
Connect one stereo pair per zone: the left and right speakers of the same pair must be connected to the same zone (Z1, Z2, Z3, or Z4) to maintain the stereo effect
Isolate the bare wires: ensure that the exposed wires do not touch each other or contact any metal parts of the device
Turn the amplifier back on

You can independently manage the volume of each zone using the provided infrared remote control. Also, make sure to maintain at least 8 cm of space around the device and not block the ventilation openings.
