Frequently Asked Questions - Ai41 -Ai81 Outline

What is the difference between the Outline Ai41 and Ai81?

The Ai81 has eight 1.3" drivers instead of four, providing higher power handling and SPL. Both are ultra-slim columns with identical 160° horizontal dispersion.

What amplifier should I use with the Ai41/Ai81?

Use a high-quality amplifier with appropriate power. The Ai41 can handle 10W continuous (160W peak), while the Ai81 handles 20W continuous (320W peak). Always use the suggested Outline amplifiers and DSP presets for optimal performance.

Can I install the Ai41/Ai81 outdoors?

The cabinet features hydrophobic HCDF and polyurethane paint, making it suitable for tough environments. For outdoor use, ensure proper weatherproofing and follow local regulations.

How do I connect the loudspeaker to the amplifier?

Use a 2-pin Euroblock connector, feeding the amplified signal with correct polarity. Use cables with max 4 mm² cross-section (AWG 11).

Can I mount the speaker on a wall or ceiling?

Yes, the Ai41 has two through holes and two M4 rear points; the Ai81 has two through holes and three M4 rear points. You can also use the optional AIWALL01 tiltable bracket.

What is the maximum sound pressure level?

The Ai41 reaches 107.5 dB, and the Ai81 reaches 112 dB (calculated with AES2-2012 test signal, half space).

What type of drivers are used?

Both models use 1.3" neodymium magnet full-range drivers and a 0.7" treated silk dome tweeter, delivering wide nominal dispersion and high output.

What is the frequency response?

The Ai41 responds from 280 Hz to 20 kHz (-10 dB), while the Ai81 responds from 300 Hz to 20 kHz (-10 dB).

Does the speaker require a special crossover?

No, the Ai41 and Ai81 include a passive crossover with top-grade miniature components that splits LF and HF and protects the drivers. Only one amplifier channel is needed.

How do I clean and maintain the speaker?

Use a dry cloth for the cabinet; avoid solvents. Periodically check transducers impedance, cabinet, grills and screws. For internal repairs, contact qualified service personnel.

SAFETY REGULATIONS

In order to avoid risks for the user's and other people's safety, as well as annulling the warranty, it is advisable to read the suggestions in this section for correct use of the product.

The user must assume the responsibility for making sure that the use of any rigging system and its components in any particular circumstance or venue conform to all applicable laws and regulations in force at the time.

This unit was designed as part of a sound reinforcement or audio recording system.

Any use other than that foreseen by the manufacturer is carried out under the sole responsibility of the user.

- The unit must ONLY be connected to the amplified output of an amplifier, a powered mixer or another unit with this type of output (e.g. a self-powered loudspeaker enclosure with an amplified auxiliary output). A suitable power cable in compliance with current safety norms must be used to connect the unit.

• The amplifier connected to the unit must only

be switched on after having connected and switched on all the other components of the sound reinforcement/recording system, to avoid annoying noises that can sometimes damage the loudspeakers.

• The unit must only be moved when the cables are disconnected.
• Only dedicated accessories, specifically designed for the system, or any standard accessories foreseen may be used when installing.
• The mechanical operation of the product and the accessories used must be checked periodically.
• This unit produces high sound pressure levels that can damage hearing if listened to under incorrect conditions.
• The unit must only be opened and/or repaired by specialist staff.
• For any requirements of a technical nature, contact OUTLINE or authorized staff.

The CE declaration of conformity is attached to the product warranty certificate and is shipped with the product.

SYSTEM DESCRIPTION

The Ai41 and Ai81 are 2-way passive ultra-slim column loudspeakers specifically designed to ensure a minimal-discreet visual impact and an elegant design for an easy and seamlessly layout integration while ensuring the sound quality for which Outline has always been recognized.

These tiny, modular, externally powered loudspeakers provide the best performance when installed on a flat surface. Ai41 and Ai81 feature four and eight 1.3" neodymium magnet driver respectively and one 0.7" treated silk dome tweeter producing a wide nominal dispersion and impressive maximum SPL.

Also, a passive crossover (manufactured with top-grade miniature components) takes care to split the LF and HF and provides protection for the drivers.

All the above enclosed in a compact, refined and elegant design.

The cabinet, in HCDF (Hydrophobic Compact Density Fiber), is coated with polyurethane paint ensuring the correct operation even in the toughest places; while the grill, made of galvanized steel, features an epoxy powder coating. Custom RAL colour options are available to perfectly match any architectural layout.

AMPLIFIER CONNECTION

Ai column loudspeakers have a passive crossover, therefore the unit requires just one amplifier channel.

The connections are available on a 2-pin Euroblock socket. The amplified signal shall be fed following the polarity sign on the connector (+/-). Use cables with a maximum cross-section of 4 mm ² (AWG 11).

The system shall be used with the suggested Outline amplifier and presets DSP.

MOUNTING INSTRUCTIONS

This system offers more than one way to install the loudspeaker as needed.

To install the column either on wall or on a flat surface there are two through holes dedicated as

shown in the figure below.

For this application, do not use screws with diameter greater than 4 mm.

Proceed as follows:

• Remove the grill, held by magnets,
  • mark the points on the affected surface,
  • create the fixing points,
• fix the cabinet,
• reposition the grill.

The Ai 41 and Ai 81 feature also two and three M4 fixing points on the rear panel respectively, that allow to use proper accessories to mount the column.

The AIWALL01 is a tiltable bracket for applications where a specific aiming is required or the surface does not allow wall mounting.

To mount the bracket follow this procedure:

• Unscrew the two parts removing the pin,
• mount the wall plate (using the guides to make the fixing points),
• attach the cabinet to the other plate using the two screws provided,
• join the two parts together with the pin, positioning the column in the desired position.
