Frequently Asked Questions - AXIR Audac

How do I determine the correct mounting height for the AXIR?

The mounting height is determined by aiming the 0° axis of the speaker just above the ear level of the farthest listener. Refer to the table in the manual for distance and height relations when using a 5° angle.

Can I use the AXIR in low impedance mode?

Yes, the speaker can be switched from 100V to 6Ω low impedance mode by changing internal switches. Both switches must be set to the same position.

How do I adjust the power taps for each speaker section?

Remove the front cover plate carefully with a flat tool. Two rotary switches are visible; use a screwdriver to set each to 20W, 10W, 5W, or 2.5W.

What is the purpose of two individual power tap selectors?

They allow creating specific polar patterns by setting different power levels for the upper and lower speaker sections, adapting sound coverage to the room.

What are the wiring connections for 100V and low impedance modes?

For 100V, use pins 1 and 3 (outer pins). For low impedance (6Ω), use pins 1 and 2 (center and one outer pin). Observe polarity markings.

How do I ensure high-frequency audibility?

Mount the speaker so that it is clearly visible to all listeners. High frequencies are directional and can be blocked by obstacles, creating a 'sound shadow'.

What is the recommended mounting angle for a large listening area?

For maximum listening area, use an angle of about 3°. For minimal variation in sound pressure level, use an angle of 5°.

Can the AXIR be mounted outdoors?

The manual does not specify outdoor use, but the aluminum construction may allow indoor or sheltered outdoor use. Avoid constant vibrations and moisture.

How do I clean the AXIR speaker?

Use a soft, dry cloth. Do not use water or cleaning agents. Avoid dust buildup on the grille to maintain sound quality.

What accessories are included with the AXIR?

A wall bracket is included. The speaker is available in white or black and comes with a 3-pole Euro terminal block connector.

Chapter 1

Warning

• Only use the correct amplifier output voltage and impedance, exceeding these limits could cause damage, fire or other failures.
• Only install the speaker on surfaces that can accommodate the weight of the speaker and the mounting bracket.
• Don't use any other mounting method than specified.
• Attach a safety wire to the speaker when it's mounted high up. This ensures that the speaker can't fall down in any case.
• Avoid mounting the speaker in locations exposed to constant vibrations. The mounting bracket can be damaged by excessive vibration, potentially causing the speaker to fall down.

Caution

• Avoid electric shocks: turn off the amplifier when connecting the speaker.
• Don't operate the speaker for an extended period of time at distorted sound. This can cause irreparable damage to the speaker.
• Don't stand or sit on it, nor hang down from the speaker as this may cause it to fall down or drop.

Chapter 2

Installation

To achieve the best possible intelligibility and sound quality with a column speaker, there has to be paid extra attention to the proper mounting of the speaker.

The dimensions of the desired listening area has to be determined where out the correct mounting height and angle can be derived.

A step by step installation procedure describes the method to determine the mounting height and angle for the AXIR.

DETERMINING LISTENING AREA AND MOUNTING HEIGHT

STEP 1:

Determine the dimensions of the desired Listening Area. This is a horizontal plane at the level of the listeners cars. Refer to the dashed line in following figure.

STEP 2:

After the listening area, determine at which angle the loudspeaker array has to be mounted. The AXIR column speaker was designed to aim the sound just above the heads of the listeners, and it is recommended not to exceed an angle of 6^ . There are two different approaches to determine the mounting angle, each with specific advantages and disadvantages. Which approach you choose, depends on what you want to achieve: a maximum listening area or a minimal variation in sound pressure level.

- Approach 1: Maximum listening area

When a large listening area is desired, an angle of around 3^ is recommended. When you move away from the loudspeaker, the sound pressure level will be decreased. This decrease depends on the reverberation of the room in which the speaker is placed. If you want the high tones to be clearly audible, make sure the listener is able to see the loudspeaker array.

- Approach 2: Minimal variation in sound pressure level

When a minimal variation in sound pressure level is desired, an angle of 5^ is ideal for this purpose. The size of the total listening area becomes in comparison with the previous approach, smaller. The space nearby the loudspeaker ‘A’ does not belong to the listening area.

(Diagram 1 shows the relationship between ‘Λ’ and the mounting height of the loudspeaker when using an angle of 5°)

STEP 3:

When you've chosen one of the above approaches to determine your mounting angle, you proceed by determining the mounting height. This height is determined by aiming the 0^ axis of the AXIR in the desired position, precisely above the ear level of the listener who's the furthest away from the speaker. This can be adjusted by mounting the loudspeaker higher and lower on the wall.

STEP 4:

When you've determined the mounting angle and height, you can start installing the speaker.

OTHER POINTS TO PAY ATTENTION TO:

While mounting a column speaker, there are still some other points where has to be paid attention to.

- Make sure that the loudspeaker array is always visible for everyone in the listening area, to ensure a good audibility of the high tones. High tones can be compared with light. When something is between the observer and the light source, the observer can't see the light source at it's full power, this is what we call shadow.

For high tones, this is the same issue. When someone is standing between the listener and the loudspeaker, the listener is located in the sound shadow. The sound shadow will be experienced as a reduction of high tones.

- When the loudspeaker is installed at a very small angle, a large listening area can be reached. Depending on the amount of reverberation in the room and the sound shadow, the speech intelligibility on a far position may be low. In this situation, it is recommended to use more loudspeaker arrays to split the listening area.

- When you move further than the maximum position of the listening area (further than the maximum distance of the loudspeaker array), only the sound pressure level will decrease. There will be almost no tone height variation. The decreasing factor of the sound pressure level depends strongly on the reverberation of the room.

- When you are located too close to the loudspeaker array (closer than the minimum distance) a decline of the high tones will occur very soon.

- Because the loudspeakers are designed to beam the sound just above the listeners ears, it's better to mount the speakers not to high above the listening area.

- When you want to determine where exactly the edges of the listening area are located in your situation, you have to do a practical test at this location. This is a job for an experienced listener with well-trained ears. Put pink noise through the loudspeaker array, and reduce the lower tones for this test because they do not contribute to speech intelligibility. Walk around in the listening area and pay attention to the high tones. The places where the high tones decrease rapidly are the edges of the listening area.

CREATE SPECIFIC POLAR PATTERNS

The AXIR contains two individual speaker sections whose power can be individually set between 20W, 10W, 5W and 2.5W. The desired power taps can be selected by a recessed adjuster screw behind the speakers cover.

This allows us to set the total speaker power between 5W and 40W, but it also gives the possibility to create a specific polar pattern.

By adjusting the upper and lower power taps independent from each other, the sound transfer length can be adapted to each specific situation.

Following figure shows an example of a situation where by means of the two individual power tap selectors a specific polar pattern can be realized. The lower speaker section is set to a lower power than the upper speaker section. By correct focusing of the speaker the sound transfer length of the speaker can be adapted to each specific situation.

Connecting the AXIR

CONNECTIONS:

At the back of the AXIR is a 3 pole euro terminal block connector provided to connect the amplifier with the AXIR column speaker.

Depending of the speaker is used in 100V applications or low impedance applications, the wiring diagram is different. (This is done for protection reasons of the speaker) For 100V applications are the two outer pins used (Pin 1 & Pin 3) and for low impedance applications is the centre pin and one outer pin used (Pin 1 & Pin 2).

Warning: Notice the polarity markings when wiring the loudspeaker cables.

PIN	100V	6 Ω
1	-	-
2	N.C.	+
3	+	N.C.

Warning: The AXIR is default set for use in 100V applications, for use in low dance applications, the internal switches of the speaker must be switched.

LINE TRANSFORMER POWER TAPS:

To adjust the power taps of the speaker, the front cover plate with the AUDAC logo should be removed very carefully. This is best done by carefully sticking a flat object under the cover plate (e.g. a small flat screwdriver). The cover plate is coming loose, without performing large forces.

After the cover plate is removed, the two power tap selector switches are visible.

The power taps can be set to 4 different powers for each individual speaker section. Adjust the power taps by using a screwdriver to turn the rotary switch.

1. 20W
2. 10W
3. 5W
4. 25W

CONVERT FOR USE IN LOW IMPEDANCE APPLICATIONS:

⚠️Notice: Only perform this procedure if the speaker should be used in low impedance applications.

For use in low impedance applications, the internal switches of the speaker must be switched.

To reach the internal switches, the front cover plate with the AUDAC logo should be removed very carefully. This is best done by carefully sticking a flat object under the cover plate (e.g. a small flat screwdriver). The cover plate is coming loose, without performing large forces.

After the cover plate is removed, the two power tap selector switches are visible.

To reach the internal switches, the plate with the two power tap selector switches should be removed. This can be done by loosening the 6 Phillips screws whereby it is attached.

Once these screws are loose, the plate can be carefully removed out of the speaker. (Be careful with the wiring inside the speaker)

Then you will see that there are two switches provided at the side of this plate. These switches are meant to convert the speaker for use in 100V or low impedance applications.

Set the switch to 100V for 100V applications, and set the switch to 6Ω for low impedance applications.

Warning: Make sure that the two switches are always both in the same position. Make sure that it never occurs that one of them is on 100V and the other is in 6Ω position.
