4. d make sure the port is absolutely firm If it appears loose check the o ring has not dropped through the opening Top Position This port position can be useful if you need to stand the ALF4O on its end connection terminal facing Upward 03 Using the Adjustable Port System End Position gt MAX 80MM Important notes 01 ALWAYS loosen the four screws in the port 05 Ensure the rubber o ring is correctly in plate before adjusting the port position around the port and sitting within the circular rebate 02 The blanking plate MUST always be screwed down over the port opening that is not in use 06 To release the blanking plate from its position it may be necessary to push it from 035 Be sure to tighten both the port plate and the behind from within the cabinet This can be blanking plate Never over tighten the screws done via the other port opening once the port is removed 04 Use ONLY the supplied screws to fix the port and blanking plates Contact your dealer if soares are required 04 Positioning the ALF40 Free Standing The ALF40 can be positioned anywhere within a room and in any orientation location near the corner of a room will give the most bass output however it is important to allow the bass port to breathe Do not place any solid objects closer than 50mm 2 directly in front of the port Adhere the supplied rubber feet to the cabinet this will protect the product from dirt and scratches
5. ere there is more than one pair of AIWX speakers in a room decide which of the above scenarios is applicable to the system then multiply the number e g 2 1 by the number of speaker pairs Example a very large reception room requires four AlW3X speakers and the amplifier has provision for Up to six independent amplifier channels This could then be an Active 4 2 system 2 1x2 4 2 or a passive 4 4 system 2 2x2 4 4 depending on the amount of bass output required To avoid unwanted vibrations ensure the ALFAO is fixed securely to a structure or if free standing the supplied rubber feet are used 12 Specifications Dimensions 558mm x 159mm x 154mm WD Weight 5 05Kg 6 6 lbs Design Ported acoustic bandpass with built in protection circuit Compatability Optimised for Amina AlWX series speakers can also be used with other 80hm speakers Power Handling A0 W continuous Nominal Impedance 8 Ohms 4 Ohms when used in passive configurations with the AlWX speakers 100V 70V transformer option available Frequency Response 60Hz 150Hz 6dB 24dB bandpass octave slope Sensitivity 88d0B 1mM 2 85V RMS Maximum SPL Im 105 dB Port location Front or end convertible length adjustable Port diameter I D O D 59mm 1 557 45mm 1 7 Connection way binding post accepts Amm plugs Limited Warranty The ALFAO is designed to operate reliably for many years Correctly installed and in acco

8. single ALF40 to its own amplifier channel its output relative to the AIWIX AWSX pair can be set optimally In larger rooms care should be taken not to adjust the relative output of the ALF40 too high This may result in the unit reaching its mechanical limits well before that of the accompanying AlWX speakers If this is the case consider using two ALF40 s Active Stereo 2 2 Connection Options Active 2 2 Active Stereo 2 2 AIW5X pair 2x ALF40 Multi channel Amplifier For systems using a pair of AIW5X speakers two ALF40 s will be necessary In this scenario the amplifier will need four independent channels This setup will work equally well with a pair of AlWSX speakers 11 01 02 03 04 Setup Tips When setting up any of the above system scenarios it is advised to experiment with connecting the ALF40 in reverse phase with respect to the AlWX series speakers Often the reverse phase connection results in better integration and slightly higher sound pressure level through cross over region Using pink noise can be a good way of judging the difference between the in phase and reverse phase connections In scenarios 2 3 only a maximum number of two ALF40s may be connected in parallel to a single amplifier output amplifier must be 4 ohm stable This will help provide the correct low frequency sound pressure levels in large rooms without the need for additional amplifier channels Wh
9. when positioned on the floor Fixing Brackets Use the supplied brackets to secure the ALF40 to a solid structure Use only the supplied 12 5mm screws to fix the brackets to the cabinet Never use longer screws as these may damage the units internal components Ensure the brackets are not fixed over the port plate blanking plate or connection terminal Concealed Placement The ALF4O can be placed within furniture behind wall panelling or even within a ceiling cavity Whatever structure you install the ALF40 inside it is important to create a suitable hole for the port to protrude through allowing it to breathe into the listening room Use the brackets and screws provided to secure the ALF4O within the structure In Ceiling The illustration on the next page shows how the brackets supplied can be used to fix the ALF 40 toa ceiling joist Notice the port protrudes from the cabinet this allows it to then protrude through a suitable hole cut in the plasterboard ceiling layer The supplied Port Trim may be placed over the port opening to improve its appearance this is detailed on the next page Alternatively a suitable lighting fixture bezel may be used in a similar way The Port diameter dimension of 45mm is designed so it is the same dimension as a GU10 light bulb this will help when fitting a lighting fixture bezel Ensure any fixtures used are securely fitted to avoid audible vibrations Note When using a lighting fixture bezel
