1. 1 5 to 2 mm material remove any uneven surface using light sandblock dryfit and using appropriate glue for materials used spread on both surfaces and press into place Applying pressure let dry thoroughly and secure using the synthetic mounting blocks with glue and wood screws Using proper tools crimp wire connections Properly installed the AIW speaker will propagate the vibrations through to the surface without any noticeable degradation of the sound quality If the back is open to the room it is strongly advised to create a backbox using using 1 x 1 2 strip frame glued around the perimeter of the back of the panel place a sound blanket fibreglass or acoustic absorbent material on the back of the speaker and cover with a fitting back leaving an exit for the connecting cable This way the speaker is protected and does not radiate into the space behind it 16 APU 2 Protection filters and Warranty requirements All AIW speakers come with an APU 2 protection filter which is to be calibrated to allow the maximum SPL for the unit it connects to with a current limiter and fitted with a 120Hz 20db Octave Filter This unit is to be installed actively in line with every speaker in order for the AMINA Warranty to be in effect APU channel protection provide a stable impedance with a proper 8 ohm load 6 20 DCR connected only Do not follow this device with a variable load such as an serial potentiometer for volume control as the high2. Z will interact with the filter design and alter the function and reliability of the APU 2 voiding all warranties implied or expressed by the manufacturer j Note that all APU 2 filters supplied should be considered to be set up to their highest output J1 the setting for the AIW5X unless specifically marked and one is certain that the setting has not been altered So before connecting them open the APU 2 units up by removing the four small screws in each corner using a 1 philips screwdriver and set the jumpers J1 3 and J4 6 to the appropriate selection FOR BOTH CHANNELS Failure to do so shall render the warranty on the speaker void Each Channel can be operated independently This is handy if AIWX panels of different power ratings are being controlled by the same 2 channel APU 2 I E channel 1 AIW5X setting using J1 and for channel 2 for instance an AIW1X setting using J3 or any other combination A single APU 2 is needed when using an AlW2X or AIW4X Dual input stereo versions AIW2X and 4X were designed to acoustically maintain spatial information or the room sound which is otherwise lost when electronically combining a left right signal in which out of phase information between channels is cancelled This maintains the original performance characteristics and enhances the listening pleasure The AlW2X and AIW4X are capable of providing the same efficiency and SPL output as their single input counterparts AlW3X and AIW5
3. becoming a resonant bass trap killing as much sound as possible into adjoining spaces Put in some extra drywall screws in the area adjacent to the speakers to make sure that the studs and drywall are tight to each other and the wall or ceiling will not be popping screws Often our installers use some batten or fibreglass regardless of whether a backbox is used or not just to dampen both the cavity and keep dirt from falling on the box or speakerpanel Laying a thin layer between the speaker cable and the panel especially in ceiling applications also helps to keep any connector cables away from the frame of the speaker avoiding a possible cause for unwanted sounds 3 Installation using Blocks When installing the speakers in a cavity where no sound attenuation or back box is required you shall be using the supplied synthetic blocks Hold the blocks in position with one hand behind the drywall with the appropriate side facing towards the speaker blocks are reversible for 1 2 or 5 8 application and have a specific depth adjustment With only the rubber mounting area showing overlapping the corner and as close to the studs as possible fasten with several drywall screws 2 minimal making certain the blocks are flat and tight to the back of the drywall with the screws sturdy and recessed without crunching the drywall SAFETY NOTE make sure you do not hold the block where the screws may protrude through the back as you will not like the
4. edge of the drywall and peel off the drywall paper around where the speaker goes just down to the gypsum surface Using a mall putty knife blade square to the surface or sanding block gently draw it along the edges and chamfer the gypsum to meet the required depth to hide the tape and top coat after which use a vacuum to get rid of any dust or chunks in and around the cavity This creates a slight recess in which the first paper or gause tape will disappear 9 CONNECTING THE SPEAKER Using an appropriate crimp tool do not attempt to use anything else connect the speaker wires to the speaker leads positive to RED and negative to Blue It is extremely important that speaker pairs are wired in the same manner as a reversal of polarity will have impact on sound quality and spatial reproduction When using a backbox place the speaker within the opening on top of the rubber seal of the back box flanges making sure the connecting cable cannot touch the back of the speaker nor can rattle or vibrate within the back box Often techs will use batting as in fibrefill or pink insulation between the cable speaker and back box to prevent any accidental vibration 10 Mounting the Speaker Panel into the cavity When using a backbox use four Number 8 by 3 4 stainless steel round head metal or self tapping machine screws and screw the speaker baffle through the mounting holes with the self tapping screws into the speaker mounting flange of the back

6. X respectively when driven by a mono source equally on both channels It is not recommended that these stereo units are wired from a single amp channel in parallel or series after the APU 2 as the impedance presented to the APU 2 will not be appropriate to the design of the device and render it ineffective The APU 2 provides the factory required protection and needs to be installed after the amplifier be accessible prior to the cables entering the wall Remember the APU 2 comes always preset to AIW 5 having the jumper installed at the J1 and J4 settings These are the appropriate settings for the AlW series speakers AIW1X J3 J6 20W AIW2X J3 J6 20 W per channel x 2 AIW3xX J2 J5 40W AIW4X J2 J5 40W per channel x 2 AIWSX J1 J4 80W Fig 1 Figure 1 shows the APU 2 set up for 2 x AIW3X or 1 x AIW4X using J2 and J5 After setting the APU 2 using a marker to indicate the settings on the front label 17 APU MULTI CHANNEL UNITS This June 2009 will also see the release of the first in a series of multi channel Passive HPF Protection circuits with capabilities of providing up to eight individually adjustable APU channels in a 1 U high 19 rackmount unit Further details of connections and technical specifications will be made available Figure 2 and Fig 3 provides a front and top view of the APU R 8 channel unit FIG 3 The APU 8 can replace up to 4 APU 2 units providing the installer with a slee

8. do not make the hole in both the grommet gland and sound blanket larger than the speaker wire you are going to feed through Only a sealed tight fit will provide the maximum sound absorption the back box was designed to provide Slip the top of the back box through the cavity moving it up beyond the final location so the bottom can fit through the hole and pull the box back down to the point where both locator tabs are centered in the cut out the mounting area is behind the drywall and the sides of the box are in line with the sides of the wall opening so the speaker may be installed without obtrusions onto the gasket Use eight x 1 inch drywall screws preferably fine threat used for steel studs and screw both the top and bottom flange tight through the drywall making sure the box surface is tight and even to the drywall and no debris or paper can interfere with the mounting flange and rubber seal Make sure to use at least 4 drywall screws per flange 2 left and 2 right of the popup locator lio Further secure the drywall to the studs with some extra screws up to 6 above and below the cut out just to make certain that there is no chance of the stud and drywall resonating Next dry fit the speaker making certain it fits without jamming or rubbing against the edges IMPORTANT If you are using inch drywall discard the four 1 3 thick aluminum spacer strips that came with the back box If you are using 5 3 drywall remove the back
