Amina Protection Units – APUs

Rack Systems

Our Multi-Channel Protection Unit solution.

Compact Protection

Passive rack-mounted protection unit for Amina Invisible Loudspeakers. For use in installations with higher numbers of low-impedance speakers with a centralised AV rack. Direct-to-PCB screw terminal-blocks allow for fast and easy permanent installation. Either 8 or 16 channel options available.

 

Highly Flexible

With each channel containing a selectable HPF and self-resetting thermal fuse circuit, you can be sure that each speaker will perform safely even when pushed to its limits. Please note that each channel should be set to the appropriate protection group as per below guide.

‘C’ version APU’s include improved low frequency performance for use with Amina Edge Series Invisible Loudspeakers.

Please confirm model at point of purchase – for example APU-RS16iC for Edge7.

‘Non C’ version APU’s have a slightly higher HPF setting, appropriate for loudspeakers with limited LF extension such as iQ.

Please confirm model at point of purchase – for example APU-RS16i for Mobius5.

Single Channel Protection

One unit per speaker.

In-line

Single channel in-line protection unit for use with all low impedance Amina loudspeakers. Connected to the output terminal of the amplifier before the loudspeaker cable to allow maximum loudspeaker performance for a lifetime.

Can be easily dressed back with any cable management system.

Compatibility

Each unit contains an individual HPF and self-resetting thermal fuse specific to one particular loudspeaker model. Please ensure that the appropriate APUi is connected to each loudspeaker. See compatibility table below.

‘C’ version APU’s include improved low frequency performance for use with Amina Edge Series Invisible Loudspeakers.

Please confirm model at point of purchase for example APUi70C for Edge7

‘Non C’ version APU’s have a slightly higher HPF setting, appropriate for loudspeakers with limited LF extension such as iQ.

Please confirm model at point of purchase – for example APUi50 for Mobius5.

Backboxes

Cavity Wall

Providing mounting, enhanced performance and acoustic isolation in cavity wall and ceiling constructions.

Cavity wall backboxes  are an easy to install mounting option in plasterboard cavity walls and ceilings (drywall) for Amina Invisible Loudspeakers . They create an acoustically tuned cavity behind the speaker, ensuring both consistent loudspeaker audio quality as well as minimising rearward airborne sound transmission.

Further Mounting Options

Mounting Blocks

For use when there is insufficient cavity space for an Amina cavity backbox (less than 75mm). Allows installation of Amina loudspeakers into plasterboard with a rear cavity depth of just 30mm – Please note, rear of loudspeaker should be covered using soft insulation material where mounting blocks are used to prevent ingress of debris over time.

Mounting block options for a range of plasterboard thickness are available, please state plasterboard thickness at time of order.

Shims

Shims available to allow alignment of speaker and backbox with any thickness plasterboard other than 12.5mm (1/2″) (or multi-layered build-up), ensuring that no more than 2mm plaster is applied to the front of a plaster-over loudspeaker.

May also be used for alignment in a retrofit installation or alignment of Edge Series speakers.

Loudspeaker Shims

These should be used where plasterboard thickness is greater than 12.5mm (1/2″), these will push the speaker forward.

To calculate correct loudspeaker shim requirement:

(Total plasterboard thickness) – 12.5mm = Shim thickness required

Example:

Double skin 12.5mm board: (2 x 12.5) – 12.5 = 12.5mm speaker shim

 

Backbox Shims

These should be used where plasterboard thickness is less than 12.5mm (1/2″), these will push the backbox and speaker assembly to the rear.

To calculate correct backbox shim requirement:

“12.5mm” – (total plasterboard thickness) = Shim thickness required

Example:

Single skin 10mm board: 12.5 – (10mm) = 2.5mm  backbox shim

 

Please specify shim type, backbox size (CV345/300/200) and required shim thickness at time of order

 

 

Commercial Speakers

High Impedance 100V/70V Line Transformers

Providing a great solution for high end commercial installations, all Amina Invisible Loudspeakers can be supplied with high-quality toroidally wound transformers for both 100V and 70V line systems.

With a choice of either fixed-power or multi-tapped transformers available for all Amina Loudspeakers, the ability to specify a flexible and high performing invisible system has never been easier. Multi-tap transformer allows for adjustment to specification up to the moment of installation. Multi-tap transformer shown fitted to iQ3 (iQ3+MT).

Multi-tap Transformer (MT)

100V tappings – 5W, 10W, 15W, 20W

70V tappings – 2.5W, 5W, 7.5W, 10W

 

Fixed-value Transformer (100/70T)

Options for fixed-value 20W, 40W or 60W transformers available if required.

Note:

Transformer value must be equal to or lower than the power rating of the loudspeaker it is being used with. Custom rated transformers may be available. Please contact your distributor if you have any special requirements.

 

Ordering

Please state required amplifier voltage and power requirements at time of placing order. Please note that addition of transformers may increase lead time.

Example:

iQ3+MT, Mobius5+100/40, Edge5+MT.
