Introduction This introduction briefly describes the possibilities of the AXIR design column speaker.. T he AXIR was designed to meet professional demands en proves its worth in auditoria, conference rooms, meeting rooms, churches,… any place that requires a great flexibility in positioning and tuning, ass well as state-of-the-art audio quality and design. Key features: - High-quality 2 inch speakers, especially designed by AUDAC, make the AXIR suitable for music and speech.
1 Chapter 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.
2 Chapter 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.
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.
Valid for an angle from 5° to 10° 5° - 10° 0°-axis X A (cm) Listening area Height X between listening area and speaker 100 80 60 40 20 0 0 0,5 1 1,5 2 2,5 Distance A between speaker and listening area 6 3 (m)
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.
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.
3 Chapter 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).
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.
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).
